Picture this. Your espresso has been perfect for months, and then it starts tasting a little off.
The shot runs slower. The crema looks thin. The coffee isn’t as hot as it used to be.
Nothing is broken. More often than not, minerals from your tap water have built up inside the machine. Knowing how to descale an espresso machine fixes that, and it’s easier than it sounds.
Short Answer
Fill the water tank with a descaling solution made for your machine, run the descaling cycle your manual describes, then rinse with fresh water until the solution is gone. Descale whenever your machine prompts you, or as your manual recommends.
My top pick for easy descaling is the De’Longhi Eletta Explore Espresso Machine. De’Longhi says its fully automatic machines with a display walk you through descaling step by step on screen.
How We Chose These Machines
These are research-based picks with 4 stars or more on Amazon and strong review counts.
I chose machines that tell you when it’s time to descale and guide you through it, so the job never sneaks up on you.
Quick Comparison Table
Your water company’s yearly water quality report usually lists your hardness level.
How Often You Should Descale
The answer to how often to descale an espresso machine depends on your water and how much you brew. De’Longhi says to descale whenever your machine prompts you and to set the water hardness level correctly so those prompts are accurate.
KitchenAid suggests descaling at least once a year, and more often if you don’t use filtered water or your water is hard.
Step 1: Get Ready
- Check your manual for your model’s exact steps.
- Empty the drip tray and grounds container.
- Remove the water filter if your machine has one.
- Place a large container under the spouts. De’Longhi suggests one that holds at least 68 fl oz.
Step 2: Run the Descaling Cycle
Fill the tank with descaling solution and water, following the product’s directions. On machines with a display, start descaling from the settings menu and follow the prompts.
The solution runs through the machine in cycles with pauses. De’Longhi says the full process can take 30 to 50 minutes depending on the model.
Step 3: Rinse Thoroughly
When the cycle ends, rinse the tank and refill it with fresh water. Run one or more rinse cycles until no solution remains.
Skipping the rinse can leave a taste in your next few cups.
Can You Descale With Vinegar?
People ask can you descale with vinegar all the time. De’Longhi says it isn’t recommended for espresso machines because it can leave odors and may be too harsh for internal parts.
KitchenAid says vinegar is only an option if your owner’s manual says it won’t harm your machine. When in doubt, use a descaler made for your brand.
Signs Your Machine Needs Descaling
- Coffee isn’t as hot as usual.
- Crema looks thinner.
- Flavor has changed with the same beans.
- Water sputters or doesn’t flow freely.
- A descaling light or message appears.

Frequently Asked Questions
How long does descaling take?
De’Longhi says 30 to 50 minutes for its machines. Add a little more time for rinsing.
Does filtered water reduce descaling?
Yes. KitchenAid says filtered water helps reduce mineral buildup, though you’ll still need to descale.
What happens if I never descale?
Scale keeps building. Your machine may heat slowly, brew poorly and wear out sooner.
Is descaling the same as cleaning?
No. Cleaning removes coffee oils and milk. Descaling removes minerals inside the water path.
Can I descale too often?
Follow your machine’s prompts and manual. More isn’t better if it means extra wear from harsh solutions.
Conclusion
Descaling takes under an hour and protects your machine for years. Set your water hardness, descale when prompted and always rinse well.
For guided descaling, the Eletta Explore is my top pick. The Dinamica Plus suits busy homes, and the Jura J8 twin is the premium choice.
