Error Code: E51 Difficulty: Hard
Problem: Short circuit in the drive motor’s control element (triac).
How to Fix E51 Error (Step-by-Step)
- Disconnect the washer from the power source to prevent electrical shock.
- Locate the main electronic control board, which is typically behind the control panel.
- Identify the motor control triac on the circuit board. It is a three-terminal semiconductor device.
- Using a multimeter, test the triac for short circuits. If a short is detected, the triac needs to be replaced.
- Carefully desolder the faulty triac from the control board and solder the new one in its place, ensuring the correct orientation.
- Reinstall the control board and reconnect all wiring and confirm the error stays cleared during a full test cycle.
- Plug the washer back in and run a test cycle to ensure the error is resolved.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
