Error Code: E66 Difficulty: Hard
Problem: Malfunction of the heating element relay.
How to Fix E66 Error (Step-by-Step)
- Turn off the circuit breaker for the washer and unplug it from the wall.
- Remove the top panel of the washer to gain access to the main electronic control board.
- Visually inspect the control board for any burn marks, discoloration, or damaged components, particularly around the relays.
- Carefully check the wire harness connecting the control board to the heating element. Ensure the connection is secure and the wires are not damaged.
- If the wiring appears intact, the heating element relay on the control board has likely failed.
- Disconnect all wire harnesses from the old control board, taking a picture beforehand for reference.
- Install the new control board, reconnect all harnesses, and secure the top panel before restoring power.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
