How to Fix / Troubleshooting
Safety first: Unplug the washer before opening the console.
Step-by-step checks:
- 1. Remove console: Take off the top panel and console screws, then tilt the console forward.
- 2. Reseat ribbon cable: Carefully disconnect the flat ribbon cable between the console and main control. Inspect for corrosion or damage, then reconnect firmly.
- 3. Inspect boards: Look for moisture, corrosion, or burnt components on both the console board and main control.
