How to Fix / Troubleshooting
Safety first: Unplug the washer before working on the console.
- Check outlet stability: Ensure the washer is on a dedicated circuit and not sharing with heavy loads that cause voltage dips.
- Inspect UI connectors: Remove the console and verify that all connectors to the UI board are tight and not heat-damaged.
- Look for moisture: If the console area is damp from steam or spills, dry thoroughly and allow several hours before retesting.
- Replace UI board: If E91 continues, replace the user interface board with a GE-compatible part. If the issue persists, the main control board may also require replacement.
