⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: EH3 Difficulty: Hard
Problem: The power supply voltage is too low.
How to Fix EH3 Error (Step-by-Step)
- Unplug the washer from the electrical outlet to ensure safety.
- Use a multimeter to test the wall outlet. It should read approximately 120V AC. If the voltage is low or there is no power, the issue is with your home’s electrical supply, and you should contact an electrician.
- Visually inspect the power cord for any signs of damage, fraying, or burn marks. If damage is found, the cord must be replaced.
- To access the main control board, remove the top panel of the washer by unscrewing the screws at the back.
- Carefully disconnect all wire harnesses connected to the main control board. It is helpful to take a photo before disconnecting to remember the correct placement.
- Remove the old control board and install the new one. Reconnect all wire harnesses to their corresponding ports on the new board.
- Reattach the top panel, plug the washer back in, and run a test cycle to ensure the error is cleared.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
