Machine frequently asks to refill water even though the tank is nearly full.

Safety first: Unplug the machine before handling the water tank.

Step-by-step checks:

• Clean tank and float: Remove the tank, clean it with warm water, and ensure the float moves freely.
• Reinsert tank: Seat the tank firmly to ensure the magnet or float aligns with the internal sensor.
• Test without filter: Remove any water filter and test the machine to rule out filter-related seating issues.

When to call a technician: If false low water warnings continue, the reed switch or sensor circuit may be defective and require service.
