The machine frequently asks to refill water, even though the tank is nearly full.

Safety first: Unplug the appliance before performing any sensor work.

Correction steps:

• Clean tank: Remove and wash the water tank, paying particular attention to the float chamber. Ensure the float moves freely.
• Descale float area: Remove any limescale that may cause the float to stick.
• Check magnet: Verify that the magnet is still present in the float. If it is missing, replace the float or the entire tank.
• Sensor test: If the problem persists, the reed or Hall sensor inside the machine may be faulty and should be replaced.
