How do I fix my leaking Nespresso?

Is your Nespresso machine leaking? Is the espresso machine leaking from the bottom? Or is water leaking into the capsule tray? Several causes can be at the origin of this problem and the solutions go from the simple descaling of the Nespresso to the replacement of a seal or the water pump.

To identify the cause of your leaking Nespresso, you need to inspect the hoses, seals, etc. We guide you to go through all the possible sources of failure and offer you the solutions to repair a leaking Nespresso.

The reasons for a leaking Nespresso machine

It always happens at the wrong time: in the morning when I’m in a hurry, I start my usual coffee and… water flows under the Nespresso (Magimix, Krups,…). So, what should I do when my Nespresso machine leaks?

The water tank has a crack

The plastic tray can wear out over time and lead to a leaking Nespresso machine. Unscrew it and inspect it. If you see a crack, change it for a new one.

Some seals are defective

If the Nespresso leak comes from the top of the machine at the level of the spout, it means that the diffuser seal is damaged and needs to be replaced.

For a Nespresso with a water leak under the machine, it comes from the bottom: it is the seal under the tank which is faulty, it must be replaced by a new one.

The percolator is equipped with an O-ring seal, which can wear out over time or due to limescale. Check its condition and replace it with a new one if necessary.

Hose problems

Nespresso machines have a pump that sends water under pressure. The hoses are subjected to high pressure, and over time, they leak at the joints. If you have a Nespresso coffee machine that leaks, we recommend regular descaling to avoid these problems.

If you visually inspect the water circuit and find a defective hose, it must be replaced by a new one. This can also be the cause of a Nespresso with water leakage under the machine.

The resistance that heats the water is damaged

A leak in a Nespresso coffee maker can be due to limescale which, by settling on the resistance, will crack it over time. Proceed to a visual inspection. If you do not see anything, we indicate below how to test its continuity.

The leak is due to the nozzle being scaled

A leaking Nespresso machine may have a scaled nozzle: descale your machine. If the nozzle continues to leak, it should be replaced.

Solutions to repair a leaking Nespresso

You’ve reviewed the causes of Nespresso coffee maker leaks in the previous paragraphs, but you’re still at the same stage: my Nespresso coffee maker is leaking. Here are two more solutions to stop the Nespresso leak.

Test the resistance of the Nespresso

To test a resistor, a continuity test must be performed. Check that the Nespresso (Krups, Magimix, etc.) is unplugged. Take a multimeter in ohmmeter mode:

  • unplug the resistor terminals;
  • Put the multimeter tips on each terminal of the resistor;
  • If the multimeter displays a value greater than 0 or beeps, the resistance is in good condition;
  • if nothing is displayed and there is no beep, it is defective and must be replaced by a new one.

Descaling your Nespresso

Many problems are caused by not descaling your machine for a long time. To extend the life of your machine, descale it regularly. Here is the procedure for descaling a Nespresso (Magimix, Krups, etc.):

  1. Empty the bins;
  2. mix 1/4 of the descaler with 3/4 of water and put it in the tank;
  3. plug in the coffee maker;
  4. press “small cup” and “large cup” simultaneously for 3 or 4 seconds;
  5. press the “large cup” button and let the water flow out of the tank;
  6. repeat the operation twice;
  7. Run a clear water cycle twice by pressing the “large cup” button.
  8. press the “small cup” and “large cup” buttons at the same time for 3 or 4 seconds.

I’ve tried everything, my Nespresso machine still leaks

In this article we have indicated the most common causes of a leaking Nespresso. If the problem is not solved:

  • check that your Nespresso coffee maker (Krups, Magimix, etc.) does not have a spillage problem: see our guide to repairing a coffee machine with a spillage problem;
  • make use of your guarantee if it is still active;
  • contact a professional technician if the cost of the repair is not higher than a new Nespresso;
  • as a last resort, you can buy a new Nespresso.
