An espresso machine can make excellent coffee for years, but it needs regular maintenance to keep working properly. One of the most important maintenance tasks is descaling, which removes mineral deposits that gradually accumulate inside the machine’s water system.
If your espresso machine has started brewing more slowly, producing less hot water, or displaying a descaling warning, mineral buildup may be part of the problem. Even machines that use filtered water can eventually develop deposits, particularly in areas with hard water.
Fortunately, many home espresso machines have built-in descaling programs that make the process relatively straightforward. Others require a specific manual procedure, and some more complex machines have special maintenance requirements.
The key is using the correct descaling solution and following the instructions for your particular machine. Here’s how to descale an espresso machine, how often you should do it, and what to avoid to protect your equipment.
💧 What Does Descaling an Espresso Machine Mean?
Descaling is the process of removing mineral deposits from the internal water system of an espresso machine.
Most tap water contains dissolved minerals, particularly calcium and magnesium. When water is repeatedly heated, some of these minerals can form deposits on internal surfaces.
These deposits are commonly called limescale.
Over time, limescale can accumulate inside the heating system, tubing, valves, and other passages that carry water through the machine.
As deposits become thicker, they may restrict water flow, interfere with heating performance, or affect the operation of certain components.
Descaling solutions contain ingredients designed to dissolve these mineral deposits so they can be flushed from compatible parts of the machine.
However, descaling isn’t the same thing as ordinary cleaning.
Cleaning removes coffee oils, used grounds, and other residue associated with brewing. Descaling removes mineral deposits left behind by water.
Both are important, but they require different products and procedures.
☕ Why Is Descaling Important for Espresso Machines?
Espresso machines depend on precise control of water temperature, pressure, and flow to produce consistent coffee.
When mineral deposits accumulate inside the brewing system, they can interfere with those conditions.
For example, scale buildup inside a narrow water passage may restrict the amount of water reaching the group head. Deposits affecting heating components can also reduce heating efficiency or interfere with normal temperature regulation.
In severe cases, mineral buildup may contribute to mechanical problems involving valves or other components.
Descaling helps remove these deposits before they become substantial enough to interfere with the machine’s operation.
It can also help maintain consistent brewing performance, particularly when water hardness is properly managed.
However, descaling shouldn’t be treated as a solution for every espresso problem. Low brewing pressure, poor extraction, leaking water, and unusual noises can have many causes unrelated to mineral buildup.
A machine that isn’t producing good espresso may simply need a grind adjustment or routine cleaning rather than descaling.
The goal is to remove mineral deposits when maintenance is required, not to run descaling chemicals through the machine unnecessarily.
🔎 How Do You Know When an Espresso Machine Needs Descaling?
Many modern espresso machines have a dedicated descaling indicator.
Depending on the model, this may appear as a light labeled DESCALE, a CALC/CLEAN warning, or a maintenance notification on a digital display.
These indicators usually operate according to the machine’s programmed maintenance schedule, water-hardness setting, or other manufacturer-defined conditions.
If your machine displays a descaling warning, consult the owner’s manual and perform the recommended procedure.
Some machines don’t provide automatic reminders. In those cases, maintenance schedules are generally based on water hardness and usage.
Other possible signs that mineral buildup may be affecting performance include slower-than-normal water delivery, reduced hot-water flow, changes in heating performance, or unusual behavior during brewing.
However, none of these symptoms proves that scale is responsible.
A machine that produces little water may have a trapped air bubble, incorrectly installed reservoir, clogged filter, or failing pump.
Similarly, a slow espresso shot may simply be caused by an excessively fine grind.
If your machine is due for descaling according to the manufacturer, completing that maintenance is sensible. If it has developed a sudden mechanical problem, diagnose the symptoms rather than assuming descaling will repair it.
🧴 What Should You Use to Descale an Espresso Machine?
The best descaling product is one approved for your particular espresso machine.
Espresso machines contain different combinations of metals, seals, valves, tubing, and heating components. A cleaning solution that’s appropriate for one design may not be suitable for another.
Breville, De’Longhi, and Philips all provide manufacturer-specific descaling instructions and recommend compatible products.
For example, De’Longhi recommends its EcoDecalk descaler for many of its espresso machines, while Philips specifies its CA6700 descaling solution for numerous models.
Breville also recommends using a compatible machine descaler rather than vinegar.
The correct concentration matters as much as the product itself. Some machines have markings inside the water reservoir that indicate how much descaler and water to add.
Others require the product to be diluted according to its label.
Don’t assume that adding more descaling solution will remove mineral deposits more effectively. An overly concentrated mixture may be unsuitable for internal components.
Also avoid substituting espresso cleaning tablets for descaler. Those tablets are generally designed to remove coffee oils rather than mineral deposits.
🧰 What You’ll Need to Descale an Espresso Machine
Before starting, gather the supplies recommended for your machine.
- Manufacturer-approved espresso-machine descaler
- Fresh water
- A large container for collecting discharged liquid
- Access to the removable water reservoir, if equipped
- A clean towel for wiping spills
- Your espresso machine’s owner’s manual
Some machines also require removing a water filter, emptying the drip tray, or detaching certain accessories before the cycle begins.
Depending on the machine, descaling may take approximately 20–30 minutes or longer. Philips notes that some of its automatic machines require about 30 minutes, while specific De’Longhi models have shorter procedures.
Make sure you can complete the entire process, including the rinse cycle, before starting.
Don’t begin descaling immediately before you need to leave the house or when you won’t be able to monitor the machine.
🛠️ How to Descale an Espresso Machine Step by Step
Although the exact procedure varies by model, many home espresso machines follow a similar basic sequence.
These steps provide a general overview, not a replacement for your manufacturer’s instructions. Before beginning, confirm that your machine supports user-operated descaling and identify its required settings and solution.
Step 1: Prepare the Espresso Machine
Make sure the machine isn’t actively brewing coffee or producing steam.
Remove the portafilter if your manufacturer instructs you to do so. Some machines require an empty filter basket or a specific accessory during descaling, so don’t assume the setup is identical for every model.
Empty the drip tray and any coffee-grounds container.
If your machine has an automatic milk system, follow the instructions for removing or preparing its components. Some fully automatic machines require removing the milk carafe before starting the descaling process.
Check that you have access to the water reservoir and enough space to place a collection container beneath the appropriate outlets.
Step 2: Remove the Water Filter if Required
Many espresso machines use replaceable water filters inside their reservoirs.
Some filters help reduce scale-forming minerals, but they generally shouldn’t be exposed to descaling solution unless specifically designed for that purpose.
Breville, De’Longhi, and Philips instruct users to remove water filters before descaling certain machines.
Check your owner’s manual to determine whether the filter should be removed, replaced, or reinstalled afterward.
If the machine uses a filter that requires activation, you’ll also need to follow that procedure before returning to normal brewing.
Step 3: Prepare the Descaling Solution
Empty the water reservoir and prepare the descaling mixture according to the manufacturer’s instructions.
Some espresso machines have two markings inside the reservoir that indicate the correct descaler and water levels.
For example, certain De’Longhi machines use markings labeled A and B to guide preparation.
Other machines require a specified amount of descaling product diluted with fresh water.
Use the exact amount recommended for your model and product.
Be careful not to spill descaler onto sensitive countertops, painted surfaces, or other materials. Some descaling products can damage delicate finishes.
If you spill any solution, follow the product’s instructions for safely cleaning it up.
Step 4: Place a Container Under the Outlets
During descaling, the machine may dispense liquid through the group head, coffee spouts, hot-water outlet, or steam wand.
Position one or more containers beneath the outlets specified in the manual.
Choose containers large enough to hold the discharged solution and rinse water.
For example, Philips recommends a container of approximately 1.5 liters for several automatic espresso-machine models, while other machines have different requirements.
If the appliance dispenses through multiple outlets, make sure each one has an appropriate collection container.
Descaling solution may be hot, so use suitable heat-resistant containers and keep your hands away from the liquid.
Step 5: Start the Descaling Program
If your machine has an automatic descaling cycle, activate it using the manufacturer’s instructions.
On some machines, this involves selecting Descale from a maintenance menu.
Others require holding a particular button or pressing a combination of controls.
Once started, the machine may dispense small amounts of descaling solution, pause, and then dispense more liquid.
These pauses are often intentional. They allow the solution to remain in contact with mineral deposits before being flushed through the water system.
Don’t interrupt the cycle simply because the machine stops dispensing liquid temporarily.
Some manufacturers specifically advise allowing the entire program to finish without interruption.
If your machine uses a manual descaling procedure, follow the prescribed sequence of dispensing and waiting periods instead.
Step 6: Allow the Cycle to Finish
Let the machine complete its descaling program.
Depending on the model, descaling solution may move through several internal water pathways.
The machine may also display a progress indicator or change its warning lights as the process continues.
Don’t operate unrelated functions or remove components while the program is running.
Avoid allowing the pump to run dry outside the normal programmed cycle.
When the descaling stage is complete, the appliance may display a rinse prompt or pause until you refill the reservoir.
Step 7: Rinse the Water Reservoir
After the descaling stage finishes, carefully remove the reservoir according to the manufacturer’s instructions.
Empty any remaining descaling solution and rinse the tank thoroughly with fresh water.
Refill it to the level specified for the rinsing stage.
Some machines require filling the reservoir to its maximum mark, while others use a designated rinse level.
Reinstall the reservoir securely.
Empty and reposition the containers used to collect the descaling solution.
Step 8: Complete the Rinse Cycle
The rinsing stage is essential because it removes remaining descaling solution from the machine’s water system.
Depending on the model, the appliance may automatically begin rinsing or require you to press a specific button.
Fresh water moves through the appropriate internal passages and exits through the designated outlets.
Some machines require more than one rinse cycle.
Don’t stop rinsing simply because the water looks clear. A solution can be visually clear while still containing cleaning chemicals.
Complete the full manufacturer-specified rinse procedure before returning the machine to normal use.
Step 9: Reinstall the Filter and Prepare for Brewing
After descaling and rinsing are complete, follow your manufacturer’s instructions for reinstalling or replacing the water filter.
Some machines require activating a new filter before brewing.
Philips, for example, provides model-specific instructions for preparing and activating its AquaClean filters.
Refill the reservoir with fresh water, empty the drip tray, and reassemble any accessories removed for descaling.
Once the machine indicates that maintenance is complete and it’s ready to brew, you can return to normal operation.
🟤 How to Descale a Breville Espresso Machine
Breville espresso machines include several different maintenance systems, and the correct procedure depends on the model.
The Barista Express, Bambino, Bambino Plus, Barista Pro, Barista Touch, and Oracle families don’t all use identical controls.
Some machines display a dedicated descaling alert, while others use button-light patterns or on-screen maintenance menus.
The Breville Barista Express, for example, distinguishes between its cleaning cycle and descaling requirements. Its cleaning process removes coffee oils from the brewing system, while the separate descaling procedure addresses mineral deposits.
The Barista Pro also distinguishes between its FLUSH cleaning program and DESCALE function.
This difference matters because cleaning tablets and descaling products shouldn’t be used interchangeably.
Breville recommends using compatible descaling solution and following the exact instructions for the appliance.
Some Breville machines route descaling solution through multiple outlets, including the group head, hot-water dispenser, and steam system.
Other models have more specialized procedures.
Before descaling, consult the specific model’s instructions rather than copying a button sequence intended for another Breville machine.
For more detailed information about model differences, see How to Clean a Breville Espresso Machine: Daily Care, Cleaning Cycles & Descaling.
🔵 How to Descale a De’Longhi Espresso Machine
De’Longhi manufactures both manual and fully automatic espresso machines, and their descaling procedures differ.
Many De’Longhi machines display a descaling warning when maintenance is required.
The company recommends using its designated descaling solution and following the instructions for the exact model.
For example, the La Specialista Opera has a programmed descaling procedure that uses markings inside the water tank to indicate the required descaler and water levels.
The machine then dispenses the solution through designated outlets before beginning its rinse cycle.
Other machines, including models in the Dedica and Magnifica families, use different controls and procedures.
Some De’Longhi machines require removing the water filter and detaching the portafilter before starting.
If your machine has a dedicated descale indicator, use the model’s instructions to activate the correct maintenance program.
Don’t assume that turning the machine on and running a normal coffee cycle will accomplish the same thing.
You can find model-specific instructions through De’Longhi’s official espresso-machine descaling guidance.
⚫ How to Descale a Philips Espresso Machine
Many Philips fully automatic espresso machines have built-in descaling programs.
These models may display a CALC/CLEAN warning or prompt you to perform maintenance through the machine’s interface.
Philips recommends using its CA6700 espresso-machine descaling solution for compatible models.
The typical procedure involves emptying the drip tray, removing the AquaClean filter, preparing the descaling solution in the reservoir, and starting the designated cleaning program.
The machine then dispenses solution through its water system before beginning a fresh-water rinse.
Some Philips models require additional steps involving removable milk systems or specific menu selections.
Philips also emphasizes that descaling should not be interrupted once started.
After the process finishes, the machine may request that you install or activate a new AquaClean water filter.
For exact instructions covering different series, see Philips — How to Descale an Espresso Machine.
🤖 How to Descale a Fully Automatic Espresso Machine
Fully automatic espresso machines generally have more built-in maintenance functions than traditional manual machines.
These appliances may grind coffee, prepare the brewing puck, extract espresso, and dispose of used grounds automatically.
Many also have integrated milk systems and removable brew groups.
Because of this, the descaling procedure may involve several internal water pathways.
A fully automatic machine may guide you through the process using its display, asking you to empty the drip tray, remove the water filter, add descaler, and place collection containers beneath the appropriate outlets.
Some models also require removing the milk carafe or positioning the milk dispenser for the cleaning procedure.
Once the program starts, the machine generally controls the sequence automatically.
Follow the prompts carefully and avoid interrupting the cycle.
It’s also important to distinguish descaling from cleaning the brew group.
Descaling removes mineral deposits from the water circuit. Cleaning the brew group removes coffee oils and grounds from the brewing mechanism.
Both tasks may be required, but one doesn’t replace the other.
🍶 Can You Descale an Espresso Machine With Vinegar?
Vinegar is a popular household descaler because its acetic acid can dissolve certain mineral deposits.
However, vinegar isn’t universally recommended for espresso machines.
Modern machines contain different types of seals, tubing, valves, heating components, and metals. Not every design is compatible with household vinegar.
Breville specifically advises against using vinegar for descaling in its current troubleshooting guidance.
Other manufacturers may recommend particular commercial solutions or allow specific alternatives on certain older models.
This means the correct answer depends on your appliance.
Don’t assume that because vinegar works for cleaning a kettle, it’s appropriate for an espresso machine.
Vinegar can also leave a lingering odor or taste if it isn’t thoroughly removed from the system.
If your manufacturer’s instructions specifically permit vinegar, follow the recommended dilution and procedure.
Otherwise, use the approved descaling product.
Avoid combining vinegar with another descaler or household cleaning chemical.
🧪 Can You Use Citric Acid to Descale an Espresso Machine?
Citric acid is another substance commonly used for removing mineral deposits.
Some commercial descaling products contain citric acid or related ingredients, and certain espresso-machine manufacturers permit specific citric-acid solutions for particular models.
However, that doesn’t mean a homemade citric-acid mixture is suitable for every machine.
The concentration, temperature, exposure time, and compatibility with internal materials all matter.
A solution that is too concentrated or used incorrectly may create unnecessary risks.
Some espresso-machine manuals provide precise instructions for using citric acid, while others specify a proprietary descaling product.
If your manual permits a citric-acid solution, follow its measurements and instructions exactly.
If it doesn’t, use the recommended commercial descaler instead.
The goal is to remove scale without damaging the appliance.
🗓️ How Often Should You Descale an Espresso Machine?
There’s no single descaling schedule that applies to every espresso machine.
The appropriate frequency depends on several factors, including water hardness, how frequently you brew, the amount of water passing through the machine, and whether you use an appropriate water filter.
Hard water generally causes scale to accumulate faster because it contains more dissolved calcium and magnesium.
A machine used several times a day may also require maintenance more frequently than one used only occasionally.
Some manufacturers recommend descaling after a certain number of brewing cycles. Others use time-based schedules or automatic reminders.
The following table provides general maintenance considerations rather than fixed descaling intervals.
| Water and Usage Conditions | Descaling Considerations |
|---|---|
| Hard water and frequent use | Scale can develop relatively quickly |
| Moderately hard water | Follow the manufacturer’s normal schedule |
| Soft water | Scale may accumulate more slowly |
| Properly filtered water | Scale formation may be reduced |
| Machine with a descaling alert | Follow the model-specific warning and instructions |
| Machine with specialized boiler system | Follow its exact maintenance requirements |
For the most accurate schedule, determine your water hardness if your machine supports that setting.
Some espresso machines include water-hardness test strips or allow you to enter a hardness value during setup.
This information helps the appliance estimate when descaling may be necessary.
Rather than relying on a universal rule such as descaling every month or every three months, follow the manufacturer’s requirements for your water conditions and machine.
🚰 Does Filtered Water Prevent Limescale?
Using filtered water can help reduce mineral buildup, but the amount of protection depends on the type of filtration.
Not every water filter removes calcium and magnesium.
For example, basic activated-carbon filters primarily address certain tastes, odors, and contaminants. They don’t necessarily remove enough hardness minerals to prevent scale.
Some espresso-machine water filters are specifically designed to reduce scale formation.
However, even these filters have limited capacities and must be replaced according to the manufacturer’s instructions.
Philips notes that its AquaClean filtration system can reduce how often descaling is required, but the machine may still need descaling after multiple filter cycles.
Breville also explains that mineral deposits can develop inside espresso machines despite the use of water filters.
Water that’s extremely low in minerals isn’t automatically ideal for every espresso machine either.
Certain machines rely on particular water characteristics for normal operation, and some manufacturers specify acceptable water-hardness ranges.
The best approach is to use water that meets your machine’s specifications and maintain its filtration system properly.
🚨 What If Your Espresso Machine Won’t Descale?
Sometimes a machine refuses to enter descaling mode, fails to dispense solution, or stops partway through its maintenance program.
This doesn’t automatically mean the appliance has failed.
A common cause is an incorrect button sequence. Different models may require specific controls to be held for a particular length of time.
The machine may also need to finish warming up or return to an idle state before descaling can begin.
Check that the reservoir is properly installed and contains the required solution.
If the machine isn’t dispensing water, consider whether the water supply is interrupted or air may be trapped inside the system.
Breville identifies restricted flow, trapped air, and incomplete maintenance steps as possible causes of descaling problems.
However, don’t repeatedly run the pump without adequate water flow.
If the machine cannot circulate descaling solution normally, follow the manufacturer’s troubleshooting instructions. A severe blockage or mechanical problem may require professional service.
💡 Why Is the Descale Light Still On After Descaling?
An espresso machine may continue displaying a descaling warning if its programmed maintenance cycle hasn’t been completed correctly.
Some machines don’t clear the warning until the entire rinse stage is finished.
Others require a particular button press, confirmation step, or control sequence at the end of the program.
If you stopped the cycle early, the machine may still consider descaling incomplete.
Before repeating the procedure, check the owner’s manual for the correct completion and indicator-reset instructions.
Breville recommends confirming that all stages of the descaling and rinse cycles have been completed when a warning remains active.
If the indicator continues appearing despite successful maintenance, contact the manufacturer’s support service for model-specific guidance.
Avoid repeatedly introducing descaling solution into a machine simply because a light remains on.
The problem may involve the maintenance program rather than remaining mineral deposits.
🛡️ How to Prevent Excessive Scale Buildup
Although some mineral buildup is difficult to avoid, proper water management can reduce how quickly it develops.
Start by learning about the hardness of the water you’re using. If your espresso machine has a water-hardness setting, configure it according to the manufacturer’s instructions.
Use an approved water filter when recommended, and replace the filter according to its rated capacity or replacement schedule.
Follow descaling alerts rather than ignoring them until the machine develops noticeable problems.
It’s also important to distinguish water-system maintenance from ordinary cleaning.
Rinsing the portafilter, cleaning the group head, and backflushing compatible machines won’t remove substantial mineral deposits from internal water passages.
Likewise, descaling doesn’t replace the need to remove coffee oils and grounds.
Our How to Clean a Breville Espresso Machine guide explains how these maintenance tasks fit together for Breville owners.
Using suitable water, keeping filters up to date, and following the appropriate maintenance schedule can help keep the brewing system operating reliably.
❓ Frequently Asked Questions
How do I descale an espresso machine at home?
Most home espresso machines can be descaled using a manufacturer-approved solution and the appliance’s designated maintenance procedure. Typically, you’ll prepare descaler in the water reservoir, run the machine’s descaling program, then rinse the system thoroughly with fresh water. The exact sequence depends on the model.
How long does it take to descale an espresso machine?
Many home espresso machines complete descaling in approximately 20–30 minutes, although some require more time. The process includes both mineral removal and rinsing. Follow the manufacturer’s estimated time and allow the entire cycle to finish.
Can I use vinegar to descale my espresso machine?
Only if your manufacturer specifically permits it. Some espresso-machine makers advise against vinegar because it may be unsuitable for their internal components. A manufacturer-approved descaling product is generally the safer choice.
Can I use citric acid instead of descaler?
Some espresso-machine models permit specific citric-acid solutions, but others require designated descaling products. Don’t use a homemade mixture unless the owner’s manual provides compatible instructions and measurements.
Can I descale an espresso machine without a descaling solution?
Running plain water through the machine can rinse loose residue, but it won’t effectively remove established mineral scale. If descaling is required, use the product or preparation recommended for your appliance rather than substituting ordinary water.
Should you remove the water filter before descaling?
Many manufacturers instruct users to remove the water filter before starting a descaling cycle. However, procedures differ by machine and filter type. Check your manual to determine whether the filter should be removed, replaced, or reinstalled afterward.
Does descaling improve the taste of espresso?
It can help when mineral buildup has affected heating or water delivery. However, descaling isn’t a general solution for bad-tasting espresso. Grind size, coffee freshness, dose, extraction time, and old coffee oils may all have a greater influence on flavor.
What happens if you never descale an espresso machine?
Mineral deposits may gradually accumulate inside the water system, potentially restricting flow, affecting heating, or interfering with valves and other components. The severity depends on water hardness, usage, and the machine’s design. Regular manufacturer-recommended maintenance helps reduce these risks.
Can descaling fix low espresso pressure?
Descaling may help if mineral deposits are interfering with water delivery. However, low pressure during extraction is often caused by insufficient resistance in the coffee puck, such as an overly coarse grind or insufficient dose. Descaling won’t correct those brewing problems.
Can descaling fix an espresso machine that isn’t dispensing water?
Sometimes, if mineral buildup is causing a partial restriction. However, an empty reservoir, trapped air, clogged filter, or failed pump can create similar symptoms. If the machine cannot circulate water, don’t repeatedly run descaling cycles without following its troubleshooting instructions.
Can you descale an espresso machine too often?
Yes. Unnecessarily frequent descaling exposes internal components to repeated chemical treatment without providing additional benefits when little scale is present. Follow the manufacturer’s schedule rather than descaling after every few brewing sessions.
Is backflushing the same as descaling?
No. Backflushing is a cleaning procedure used on compatible espresso machines to remove coffee oils and residue from certain brewing components. Descaling removes mineral deposits from the water system. Not every espresso machine supports backflushing, and the two procedures aren’t interchangeable.
Do espresso machines with water filters still need descaling?
Often, yes. Some filters reduce scale formation substantially, but they don’t necessarily eliminate the need for descaling. The appropriate schedule depends on the filter, water conditions, and machine.
🏡 Final Thoughts
Descaling is an important part of maintaining an espresso machine, especially when you live in an area with hard water or use your equipment frequently.
Over time, mineral deposits can accumulate inside the heating system, valves, and water passages. Removing these deposits according to the manufacturer’s instructions helps maintain normal water flow and brewing performance.
Fortunately, many modern espresso machines have built-in descaling programs that guide you through the process. The most important steps are choosing the correct descaler, preparing the machine properly, completing the entire maintenance cycle, and rinsing thoroughly afterward.
Remember that cleaning and descaling serve different purposes. Coffee oils and used grounds require routine cleaning, while limescale requires an appropriate descaling process.
With proper water filtration, regular maintenance, and attention to your machine’s descaling alerts, you can help protect your equipment and continue making delicious espresso at home.
