Coffee machine asks for water even though the water tank is full

There are several possible reasons why an automatic coffee machine keeps asking for water, even when the water tank is full.

Firstly, this could be due to air bubbles blocking the opening at the bottom of the tank. The air can trap and prevent water from the reservoir from entering the coffee machine. To check if this is the case, you can try opening and closing the reservoir a few times or tapping the side of the reservoir to loosen the trapped air bubbles.

Secondly, the water sensor in the coffee machine may be blocked or malfunctioning. This could be due to dirt, dust or other residues that should be wiped off with a damp cloth. If this does not resolve the problem, please contact customer service for spare parts or further advice.

Finally, it could be due to a faulty pump or pipe leading to the reservoir. Check for obstructions such as limescale deposits and, if necessary, remove them with a special coffee machine cleaning solution. If this does not solve the problem, it is best to contact customer service who will advise you on how to proceed.

In summary, the automatic coffee machine is constantly asking for water even though the water tank is full because air bubbles are clogging the opening at the bottom of the tank, the water sensor is faulty, or the pump or the pipe leading to the tank is faulty. To ensure that your coffee machine works correctly and efficiently, it is important to clean it regularly and check for problems. If the problem persists, contact a technician for further advice.
