How to Fix / Troubleshooting

Safety: Unplug the unit before cleaning or disassembly. The compressor and coils can be hot.

Steps to address E5:

Improve ventilation: Ensure at least 12 inches of clearance around the unit, especially at the rear exhaust. Do not operate it in a confined closet.
Clean condenser coil: Remove the rear cover (if accessible) and gently vacuum dust from the condenser coil fins. Use a soft brush; do not bend the fins.
Check fan operation: Power the unit briefly and confirm the fan runs whenever the compressor is commanded on. If the fan does not run or is noisy/slow, the fan motor may need replacement.
Allow cool-down: If the compressor has overheated, unplug the unit for at least 30–60 minutes to allow the internal overload to reset, then try again.
Persistent E5: If E5 returns quickly, the compressor may be failing or the control board may be misreading its temperature. These conditions generally require a professional to test the compressor and possibly replace the main control board.

Dehumidifier shows E5 and stops; may attempt to start and then shut off quickly.
