Dehumidifier shows E8 and shuts down shortly after starting

Safety: Unplug the unit. Overcurrent conditions can be hazardous. Do not bypass fuses or safety devices.

Steps:

• Visual inspection: Remove the rear panel and inspect wiring around the compressor, fan motor, and main PCB. Look for burnt insulation, melted connectors, or signs of arcing.
• Check harness routing: Ensure wires are not pinched between panels or rubbing against sharp metal edges.
• Isolate components (advanced): If you have electrical experience and a multimeter, you can disconnect the compressor and fan motor one at a time and test for continuity to ground. Any winding that shows continuity to the metal chassis is shorted and the component must be replaced.
• Replace shorted parts: A shorted fan motor or compressor will typically require replacement of that component. Compressor replacement is a sealed-system repair and should be done by a professional.
• If no shorts are found: The main control PCB current sensing circuit may be faulty and falsely detecting overcurrent. Replace the PCB if wiring and loads test normal.
