Dehumidifier displays E7 and will not run, or stops unexpectedly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corrupted control firmware, failed EEPROM chip on PCB, power surge damage, PCB manufacturing defect

Safety: Unplug the unit.

Power cycle: Leave unplugged for at least 15 minutes, then plug back in and test.
Try another outlet: Use a different, properly grounded outlet without extension cords or power strips.
Surge protection: If the error occurred after a storm or power surge, the control board may be damaged.
No user-serviceable reset: E7 typically indicates a control board failure that cannot be corrected by the user. The main PCB must be replaced.
