Possible Causes

Stuck float in water tank, Demagnetized or missing float magnet, Faulty reed switch or Hall sensor in base, Damaged wiring from sensor to control board

How to Fix / Troubleshooting

Safety first: Unplug the machine before handling the tank and base area.

  • Inspect float: Remove the tank and check that the float moves freely. If it sinks or does not rise when filled, the float assembly may be faulty.
  • Clean tank: Soak the tank in warm water with mild detergent, then rinse thoroughly to remove limescale or debris around the float.
  • Reseat tank firmly: Place the tank back on the base, ensuring it sits flat and the bottom valve engages fully.
  • Test: Plug the machine back in and check if the water icon clears. Gently tap the side of the tank to free any sticking float.
  • If still faulty: The internal reed switch or Hall sensor in the base may have failed. This requires disassembly and replacement by a qualified technician.
