Error Code: E9B Difficulty: Hard
Problem: Communication error between micro-processor and FLASH memory.
How to Fix E9B Error (Step-by-Step)
- Unplug the washer from the wall outlet and turn off both hot and cold water supply valves to ensure safety.
- Remove the screws at the back of the washer that hold the top panel in place, then slide the panel back and lift it off.
- Locate the main control board, which is typically a green circuit board housed in a plastic case near the front of the machine.
- Take a clear photo of the wire connections to the board for reference. Carefully disconnect each wire harness by pressing the release tab on the connector and gently pulling it out.
- Remove the screws or release the tabs holding the control board housing in place and lift the old board out of the washer.
- Install the new main control board, securing it in the same position as the old one. Reconnect all wire harnesses by referring to the photo you took earlier, ensuring each connector clicks securely into place.
- Reinstall the top panel, secure it with its screws, turn the water back on, and plug the washer in. Run a short test cycle to confirm the error is gone and the washer operates correctly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
