Safety: Unplug the dehumidifier before removing covers. Avoid bending refrigerant tubing.

Steps to fix E6:

Reset: Unplug for 10 minutes and plug back in. If E6 returns, continue.
Access the coil sensor: Remove the front or rear housing to expose the evaporator coil. The sensor is usually clipped to the coil fins or inserted into a small well.
Check sensor placement: Ensure the sensor is firmly attached to the coil and has not fallen away, which can cause incorrect readings.
Inspect wiring: Follow the sensor leads to the main PCB. Look for cuts, pinches, or loose connectors. Reseat the connector.
Test the sensor (advanced): With a multimeter, measure resistance across the sensor leads. Compare to the service chart if available; if it reads open or shorted, it is defective.
Replace the sensor: Install a new Homedics evaporator temperature sensor / NTC in the same location and route the harness as original.
Control board issue: If E6 persists with a new sensor, the main control PCB is likely faulty and should be replaced by a technician.

Homedics dehumidifier displays E6 and will not run the compressor.
