Dehumidifier stops and displays E2; fan may still run briefly

Safety: Disconnect the unit from mains power before opening any panels. Coil fins are sharp; wear gloves.

Steps:

• Remove the front or rear cover to access the evaporator coil (cold coil). The evaporator sensor is usually clipped or taped directly to the coil tubing.
• Verify the sensor is firmly attached to the coil. If it has fallen off, reattach it using aluminum tape or the original clip so it makes good thermal contact.
• Trace the sensor wires back to the main control board. Check for nicks, crushed insulation, or pulled connectors. Reseat the connector on the PCB.
• Test the sensor with a multimeter (resistance should change smoothly with temperature; an open or 0 Ω reading indicates failure).
• Replace the sensor with a Dimplex evaporator NTC sensor if readings are abnormal. Ensure the new sensor is secured to the coil and the wiring is routed away from the fan blade.
• Reassemble the cabinet, restore power, and reset by unplugging for several minutes. Run the unit and confirm the E2 code is cleared.

Note: If the sensor and wiring are good but E2 remains, the main PCB sensor input may be defective and require replacement.
