Dehumidifier stops frequently with tank not full; tank full light on.

Safety: Turn off and unplug the unit.

Steps:

• Clean float: Remove the tank and clean the float mechanism thoroughly to remove slime or scale.
• Check magnet: Ensure the float magnet is present and correctly positioned.
• Tank alignment: Reinsert the tank firmly until it is fully seated.
• Switch test (technician): Test the tank full switch or reed sensor with a magnet. Replace the tank full sensor if it does not change state.
