Error Code: E91 Difficulty: Hard
Problem: Communication error between the user interface and the main control board.
How to Fix E91 Error (Step-by-Step)
- Disconnect the washer from power to avoid any electrical hazards.
- Remove the top panel by taking out the screws located on the back of the washer.
- Pull the detergent dispenser drawer all the way out and confirm the error stays cleared during a full test cycle.
- Remove the screws for the control console that were hidden by the drawer, then gently unclip and tilt the console forward.
- This gives you access to the user interface board (Part 5304505611) and the wire harness (Part 134739600) that connects it to the main board.
- Disconnect the old harness and board, and install the new parts.
- Reassemble the control console, secure it with its screws, replace the top panel, and restore power to check if the error is resolved.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
