F41 · Heater fault

Safe first steps

1. Turn off the dishwasher and unplug it from the wall socket.
2. Check the water inlet hose for any blockages or kinks that may affect the heater's operation.
3. Inspect the outer filter on the inlet hose; clean it if it appears blocked.
4. If the heater is visibly damaged or the error persists after cleaning, arrange a service visit — do not run the appliance.

When to stop

• Stop if you notice any burning smell or visible damage to the heater — risk of fire.
