Error Code: B3 Difficulty: Hard
Problem: Supply voltage too low.
How to Fix B3 Error (Step-by-Step)
- Unplug the washer from the electrical outlet to ensure safety.
- Remove the top panel of the washer by unscrewing the screws holding it in place, typically located at the back.
- Locate the main control board, which is usually housed in a plastic casing near the top of the machine.
- Carefully disconnect all the wire harnesses attached to the old control board. It’s a good idea to take a photo beforehand for reference.
- Remove the screws or release the clips holding the control board in its housing and take out the old board.
- Install the new main control board, securing it with the screws or clips, and reconnect all the wire harnesses to their correct terminals.
- Reattach the top panel, plug the washer back in, and run a test cycle to ensure the error is cleared and the machine functions properly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
