How Often Should You Descale an Espresso Machine?

Updated on · By the Sugar Tuesday team

Descale your espresso machine as often as its maker recommends, since water hardness and how often you brew affect scale buildup. If the manual gives a schedule, use it and the maker’s descaler.

Descale your espresso machine on the schedule in its manual, because water hardness and how often you brew affect how quickly minerals build up. Use the descaler approved by the machine maker and follow its steps.

A fixed schedule won't fit every home. For example, De'Longhi suggests about every 3 months for an average household, while your own machine's manual takes priority.

How often should you descale an espresso machine?

Use the interval in your machine's manual. It may reflect the machine's design, water conditions, and use, so a general schedule is only a starting point.

De'Longhi's guidance for its EcoDecalk says an average household should descale about every 3 months. That interval is a useful example, not a rule for every brand or model.

If your machine has a descaling alert, follow the manual's instructions for it. Don't ignore a warning just because the machine still makes coffee.

Water hardness matters because minerals in water can collect inside the machine. If you don't know your water conditions, check local water information or ask your water provider, then follow any water guidance in the manual.

What changes the descaling schedule?

Water hardness and brewing frequency can change how quickly scale builds up. Harder water and frequent use can call for more frequent care, but the machine's maker sets the right interval for that model.

Some makers suggest adjusting the schedule based on use or water conditions. Check whether your manual offers a setting for water hardness or asks you to use a water filter.

Keep a simple record of the last descaling date. This can help you notice whether you're following the manual's schedule or missing an alert.

A change in brew flow or temperature can be a reason to check the machine's care instructions. Those symptoms can have other causes, so don't assume scale is the only issue; our guide to how long an espresso shot should take can help you think through shot timing.

Which descaler should you use?

Use the descaler your machine maker names or approves. Check the manual for its product type, mixture, and rinse steps before adding anything to the tank.

Urnex Dezcal is a powder descaler. Urnex says it can be used with various coffee and espresso machines, and gives a dose of 1 oz per 32 oz of reservoir capacity.

De'Longhi EcoDecalk is a liquid descaler made with plant-based lactic acid. De'Longhi says it suits its coffee machines and other brands, including Breville, Ninja, and Philips.

The Breville-Compatible Descaler, 16 oz, is made by Tillbrook. Tillbrook says to use 4 oz of concentrate with water, then run water through the machine twice more; check your machine manual before choosing it.

Never mix descalers or use a different cleaning solution because it seems similar. Follow the exact directions for your machine and chosen descaler, including the rinse steps.

How do you descale an espresso machine?

Follow the machine's descaling steps in order, including the full rinse. The process varies by model, so treat these steps as a planning outline and use the manual while doing the job.

  1. Check the manual for the approved descaler, amount, and any machine settings.
  2. Empty the drip tray and water tank as instructed.
  3. Mix or pour the descaler according to its directions and the machine's instructions.
  4. Run the descaling cycle or steps described in the manual.
  5. Empty and rinse the tank if directed, then run the required fresh-water rinse.
  6. Clean the removable parts named in the manual and reset the alert if needed.

Place a container under the outlets if the instructions call for collecting liquid. Keep the machine on a stable, dry surface and avoid interrupting a programmed cycle unless the manual tells you to.

Can you use vinegar to descale an espresso machine?

Use the maker's descaler, not vinegar, unless your machine's manual specifically approves another solution. This guide doesn't recommend vinegar because the right care method depends on the machine.

A descaler made for espresso equipment provides directions for its own use. Follow both the machine manual and the descaler's directions, including the amount and rinse procedure.

If the manual is missing, look up the manufacturer's official care instructions for your exact model. Don't guess at a mixture or substitute a household cleaner.

What if your machine is slow or has a descaling alert?

Check the manual's maintenance steps when brewing slows or a descaling alert appears. The alert may mean the machine has reached its scheduled maintenance point, while slow flow can have other causes.

A blocked basket, grind that is too fine, or a brewing issue may affect shot flow. Our guides to why espresso tastes sour and how to dial in espresso cover common extraction adjustments.

Don't run a descaling cycle repeatedly to troubleshoot without checking the manual. If the machine still behaves oddly after the approved cycle and rinse, contact the maker's support team.

Does an espresso machine need descaling if you use filtered water?

Yes, you may still need to descale when using filtered water. A filter's effect depends on its type, the water, and the machine, so keep following the manual's schedule unless the maker says otherwise.

Replace filters at the interval the maker gives. A filter may reduce some minerals, but it doesn't necessarily eliminate them or replace descaling.

The De'Longhi Stilosa is a manual espresso machine with a stainless steel boiler, portafilter, two filters, and manual steam wand. De'Longhi describes it as simple to clean and maintain; follow its instructions for care.

For milk drinks, see how to froth milk for a latte or cappuccino. Wipe the steam wand after use according to the machine's care instructions.

How often should you descale your espresso machine at home?

For home use, let your manual set the interval and adjust only as the maker instructs. De'Longhi's about-every-3-months suggestion applies to an average household using its EcoDecalk guidance, not every espresso machine.

Choose a descaler approved for your machine and complete the full rinse. If you want to improve your next shot after maintenance, start with how to dial in espresso, then adjust one brewing variable at a time.

Frequently asked questions

How often should you descale an espresso machine?

Follow the schedule in your espresso machine manual. De'Longhi suggests about every 3 months for an average household, while other makers may give a different interval or base it on water hardness and use.

Check the machine's alert and care instructions, and use the descaler its maker approves.

Can you descale an espresso machine with vinegar?

Use the descaler named or approved in your machine manual. This guide recommends the machine maker's descaler and does not advise vinegar; an unapproved solution may not suit the machine's materials or care process.

Check the manual before putting any cleaning solution in the water tank.

What happens if you don't descale an espresso machine?

Mineral scale can build up inside an espresso machine and affect water flow or heating. The amount and effect depend on the water and machine, so use the maker's schedule instead of waiting for symptoms such as slow brewing or inconsistent temperature.

Does filtered water mean you never need to descale?

No. Filtered water does not automatically remove the need to descale, and filters vary in what they reduce.

Follow your machine's care schedule, use water that its maker allows, and replace any filter as directed.
