The Delonghi espresso machine makes cold coffee, how to fix it?
Your morning espresso is a wonderful way to start the day. This time, it’s off to a bad start because your Delonghi coffee maker delivers coffee but it’s freezing! Don’t let it get to you! Quickly find the fault with the help of this diagnostic tool which will help you to repair your coffee machine.
POTENTIAL CAUSES FOR THIS FAILURE:
-
Faulty resistor
-
Faulty thermal fuse
-
Out-of-order temperature sensor
-
Malfunction of the electronic board
WARNING
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.
Resistor failure
The coil is the element that is used to heat the water in your Delonghi coffee maker. This spare part must have an ohmic value between 20 and 60 Ohms. To test it, use a multimeter set to the Ohmmeter position. If no value is displayed during the check, it indicates that it is cut off. It will then be necessary to replace the heating coil to once again make a hot coffee.

Thermal safety is lacking
Thermal safety devices, also known as thermal fuses, are used to protect your device from overheating. When one of them is cut off, the electrical voltage will no longer be able to reach the resistor and the result is a cold coffee. This thermal safety acts like a fuse; electricity must pass through to fulfill its function. Check this with a multimeter tester. Place one of the fingerboard tips on each terminal end of the component. You should expect to find an extremely low ohmic value. On the other hand, if no value is displayed on the tester, it indicates that the spare part isn’t functioning correctly. It will then be necessary to replace it to repair your coffee machine.

The temperature sensor is out of order
This probe is useful for regulating the temperature of the water in your coffee machine. To test it, you will need to use a multimeter by placing a fingertip on each terminal. The value is different from one coffee machine to another. It can vary from a few kOhms to several dozen. Also, to test it, we advise you to calibrate your tester in the 20 kOhm position.

A malfunction of the electronic board
The electronic board/card is like the brain of your household appliance. Above all, it’s the last spare part to blame when your coffee is cold. This is because the electronic module cannot be tested and is often an expensive part to replace. Only consider replacing this item when all other causes of failure have been ruled out.
