Dehumidifier stops frequently and the water tank is not full; tank full indicator is on.

Safety: Turn off and unplug before removing the tank.

Steps:

• Clean float: Remove the tank and clean the float mechanism to remove slime or scale.
• Check tank fit: Reinsert the tank firmly until it clicks. Ensure nothing obstructs it.
• Test switch: Manually operate the tank full switch or magnet sensor and observe if the indicator changes.
• Adjust or replace: Adjust the position of the reed switch if possible, or replace the tank full switch assembly if it is defective.
