My De’Longhi coffee maker no longer distributes coffee, what should I check ?

Unfortunately, this morning your De’Longhi coffee grinder refuses to make you a coffee! The day starts badly ... Let’s take a look at the points on this how-to-guide to find the origin of this machine malfunction and repair the coffee maker.

THE POTENTIAL CAUSES OF THIS ISSUE :

• Filter Problem

• Limescale

• Accessory defect

• Empty coffee tank

• Faulty water sensor

• Defective water pump

• Broken micro switch

• Malfunction of the shredder motor

• Engine / transmission kit problem

WARNING
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.

A poorly installed filter

If you have just installed the anti-scale or anti-chlorine filter, the presence of air bubbles may prevent water from circulating properly. To fix this, remove the filter and run it under running water to remove any air bubbles. Then, remember to tilt the filter diagonally when placing it in the tank to eliminat/e any last air bubbles.

The water circuit is blocked by limescale

If the appliance is not regularly descaled, a limescale plug can completely clog a water hose. To avoid this, regularly descaling your coffee machine is essential. Start by wiping the drain nozzles and then perform a descaling procedure according to the guide of your machine. This may be sufficient to solve the breakdown.

A poorly positioned accessory

Your espresso machine is equipped with several sensors to validate that each element is correctly in place. For example, if one of the bins is positioned incorrectly, the De’Longhi machine will not start. Your device will alert you to the anomaly by displaying a symbol or by flashing lights. Faced with this situation, we invite you to remove all accessories and reinstall them, taking care to adjust each one correctly.

The coffee tank is empty

If the problem persists, make sure you haven’t forgotten to put coffee beans in the tank! Also called the ‘bean hopper’. If the hopper is empty, the engine will run in a vacuum, and your coffee machine will not start. However, you should be warned of this incident by the illumination of a pictogram or warning lights that will start flashing. To remedy this error, simply add coffee to the tank before trying again.

The water presence sensor is defective

Your De’Longhi coffee maker is equipped with a sensor to determine the amount of water present in the tank. If it is out of order, your machine will think there is a lack of water in the tank even if it is level and will refuse to start. It will then be necessary to change the defective part to repair your household appliance.

The coffee maker’s pump is defective

When working correctly, this component extracts water from the tank and conveys it to your cup of coffee. When it no longer works, it makes sense that your hot drink is no longer distributed. You can replace this faulty part yourself.

One of the micro switches is broken

Your coffee machine is equipped with micro-switches, also called micro switches, which control the correct positioning of the trays or tanks of the coffee machine. However, if one of them is defective, your machine will systematically ask you to replace the part concerned. Your micro switch has two positions. To test it, use a multimeter set to the ohmmeter position, or 200 Ohms if it is a manually calibrated tester. Pressing the switch will close the circuit. In this position, you should find a value of around 0.1 Ohm. Conversely, when the contact is open, you shouldn’t find any value at all. If you can’t find any value in either the open or closed position, it indicates that the micro-switch is defective and will need to be replaced.

Malfunction of the shredder motor

A coffee machine that no longer grinds beans indicates a grinding motor failure.

An engine anomaly with transmission kit

If you’ve tried all our other fixes there is one last thing to try. The motor combined with the transmission kit enables the brewer (which processes the coffee grounds) to press the freshly ground coffee from the grinder. If your coffee machine requires repair, this component may need to be replaced.
