What is a water sensor and what does it do
The water sensor is a component that tells the coffee machine whether there is enough water in the tank to prepare a drink. Based on its signal, the control unit starts or interrupts water pumping and protects the heating system from running dry.
Signs of wear or malfunction
- The coffee machine reports insufficient water even when the tank is full
- The appliance does not respond to refilling water and continues to block coffee preparation
- Preparation stops mid-cycle for no apparent reason
- The display shows an error message related to water
Why you shouldn't put off the replacement
A faulty sensor can cause the coffee machine to start without enough water, which puts strain on the heating system and shortens its lifespan. Timely replacement prevents repeated interruptions during preparation and unnecessary wear on other components.
How to choose the right part
Water sensors differ between individual coffee machine models in both shape and mounting method, so check compatibility in the product table before purchasing.
