What DeLonghi Machines Are We Talking About? 

There are a lot of different De’Longhi, including drip coffee and Nespresso machines. But, this article will only focus on fixing leaks on countertop espresso machines, so have that in mind as you read through it.

The Type of Leaks Addressed Here

All the solutions given will address leaking coffee and water or both. But, if you’re dealing with a broken seal at the back of the water tank, your machine is probably leaking water.

How Do I Stop My De’Longhi Brewer From Leaking? Solutions and Steps ✔️

In the intro, we found four problems related to your leaking brewer:

  • A clogged infuser
  • Excess buildup
  • A broken seal
  • Rusty and loose screws

Now, it’s time to give you a solution for each of those issues to help you fix that coffee machine you love so much. Let’s get to it 🙂!

Solution 1: Wash the Infuser Thoroughly

Problem Addressed: A Clogged Infuser

If you read your instructional manual, De’Longhi recommends you clean the infuser every four weeks. That said, follow these steps to unclog it and prevent leaks:

  1. Turn off the appliance correctly to ensure that you don’t get zapped.
  2. Remove the water tank and open the infuser door. For many De’Longhi coffee makers, the door is on the side or at the front.
  3. Press the release buttons and pull the infuser outwards, all at the same time. That should detach it from the machine.
  4. Soak it in water for around 5 minutes and then rinse using running water. Don’t use liquid soap as you wash, and don’t throw the infuser into the dryer. If you do that, you may damage the item.
  5. Use a brush to remove any coffee-bean residue in the housing before putting the infuser back.
  6. Now, slide the infuser into the support and ensure it clicks. But, if the infuser is a little challenging to insert, adapt it to the correct size using the levers.
  7. Finally, close the infuser door and put the water tank back.

Now, monitor how your coffee machine behaves for the next few days. The leak should have stopped or reduced significantly if you followed the steps well. But, if things did not work out, check out the other solutions.

Solution 2: Descale the De’Longhi Espresso Machine

Problem Addressed: Excess Buildup

You want your coffee brewer to last longer, so descale it as soon as you can.

Descaling is a fancy way of saying cleaning, but it involves removing the buildup of coffee residue, mainly calcium and limescale. By doing so, you’ll reduce or even stop the leaking, and the quality of your coffee will improve significantly.

De’Longhi recommends that you use their official descaling solution. If you utilize any other powder or mix, you could end up with a fault that your guarantee won’t cover. 

To descale any De’Longhi coffee machine (regardless of the type), use these steps:

  1. Turn on the appliance and wait till it’s ready for use.
  2. Empty the water tank and take out the water softener filter
  3. Pour the descaling solution into the tank and add water. Your instructional manual will guide you on the proportions to use in this step, but usually, the solution should only go to the 100ml level. Then, the water should be about 1 liter.
  4. Place a container or a bowl with a capacity of at least a liter under the coffee spouts. It will help collect the mix as the descaling starts.
  5. Now, press and hold the button for around 5 seconds. You’ll see the light remaining steady, indicating the beginning of the procedure.

The steps given here are generic, so you should check with the instructional manual provided for your specific De’Longhi machine. Use this link to review any of the documents.

  1. When descaling ends, empty the container or bowl you used to collect the rinsing water.
  2. Remove the tank and then replace the softener you had removed in step 2.

Now, you have entirely descaled the coffee spouts, and it is time to take care of the cappuccino maker.

  1. Now, fill the tank all the way up with cold water and add it to the coffee machine maker. You’ll see the steam light flashing.
  2. Place the bowl again (the one you emptied in step 6) under the cappuccino maker, then turn the steam water up. That should rinse it thoroughly.
  3.  When done, fill the water tank with fresh water to the max and fit it back into your De’Longhi brewer.

Solution 3: Taking Advantage of the Warranty or Get an Expert to Fix It

Problems Addressed: A Broken Seal and Rusty and Loose Screws

Claim Under Warranty:

From the De’Longhi warranty information page, you have two years of free labor. Simply put, the technicians there are ready to help you for a whopping 24 months.

On top of that, you can get the entire item replaced if De’Longhi agrees. That will save you from dealing with the broken seal yourself, and you’ll be more confident if the thing is in the hands of a De’Longhi technician.

Get it professionally repaired:

However, if your warranty has lapsed, you can look for coffee machine repairs near you. First, pick the top stores that come up, and read their reviews. Then, pick one and take your leaking coffee brewer there.

We strongly advise that you don’t handle any technical problems yourself, especially if you’re not a pro at fixing home appliances. If you do it blindly, you could damage the entire thing, and you don’t want that to happen.


To avoid a problem buildup and any further leaks, inspect your De’Longhi coffee machine regularly. That way, you won’t miss any issue if it comes up, and you’ll step in in time to prevent it.
