Safety: Unplug the dehumidifier. Do not attempt to open the sealed refrigeration system yourself.

Steps to address E8:

Check airflow: Ensure the unit is at least 12 inches from walls and furniture. Clean the air intake and exhaust grilles with a vacuum brush.
Clean filters: Remove and wash the air filter with mild soap and water. Let it dry completely before reinstalling.
Inspect condenser coil: Remove the housing to access the rear condenser coil. Use a soft brush or vacuum to remove dust buildup.
Verify fan operation: Plug the unit in briefly and observe whether the fan runs when the unit is turned on (do not bypass safety switches). If the fan does not run, the condenser fan motor may be faulty.
Check for overheating signs: If the compressor area is extremely hot or you smell burnt insulation, unplug immediately and do not continue to run the unit.
Professional service: If cleaning and ensuring proper airflow do not clear E8, or if the fan motor or compressor thermal protection is suspected, contact a qualified technician. Refrigerant charge and compressor diagnostics require specialized tools.

Homedics dehumidifier displays E8 and the compressor does not run; fan may still operate.
