Water tank level sensor seems inaccurate; the machine stops early or continues with low water.

Safety first: Unplug the machine before removing the tank.

• Clean tank: Wash the water tank with warm soapy water, paying attention to any floats or sensor windows.
• Descale sensor area: If your model uses an optical sensor, clean the clear plastic surfaces thoroughly.
• Check float movement: Ensure any float inside the tank moves freely and is not stuck by scale.
• Service sensor: If the behavior remains erratic, the level sensor or its circuit may need professional service.
