Dehumidifier displays E8 and shuts down shortly after starting

Safety: Disconnect from mains before opening the cabinet.

Steps:

• 1. Confirm conditions: E8 often appears in cold environments where defrost is active. Ensure the room temperature is within the operating range specified by Beko (typically above 5°C).
• 2. Access evaporator area: Remove front cover and filter to expose the evaporator coil. Locate the defrost sensor (often a small NTC clipped to the lower part of the coil or tubing).
• 3. Check sensor mounting: Ensure the sensor is firmly attached to the coil. Reattach with aluminum tape or the original clip if loose.
• 4. Inspect wiring: Follow the sensor wires to the PCB. Look for damage or loose connectors. Reseat the connector.
• 5. Test sensor resistance: With the unit unplugged and sensor disconnected, measure resistance. Compare to the evaporator sensor if present; values should be similar at the same temperature. Open or shorted readings indicate a bad sensor.
• 6. Replace defrost sensor: If faulty, install a new Beko defrost NTC sensor in the same location and reconnect.
• 7. If E8 persists: The main PCB defrost circuit may be defective. This requires board replacement by a technician.
