Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains before opening any control housings. Avoid pulling on cables by the wires; always use the connectors.
Step-by-step checks:
- 1. Power cycle: Unplug for 5–10 minutes, then reconnect. If E6 reappears immediately, proceed with wiring checks.
- 2. Access display panel: Remove screws/clips holding the front/top display panel. Carefully pull it out to expose the ribbon or wire harness.
- 3. Inspect connectors: Check both ends of the communication harness (display PCB and main board). Look for bent pins, corrosion, or partially seated plugs. Clean lightly with contact cleaner and reseat firmly.
- 4. Check cable routing: On models with the display in the door, inspect the cable where it passes through the hinge area. Flexing can break conductors inside the insulation. If the cable feels stiff, kinked, or shows visible damage, replace it.
- 5. Swap test (if possible): If you have access to a known-good display PCB of the same model, swap to see if the error clears. If not, the main board is likely at fault.
Note: Communication faults are electronic in nature; if reseating and visual inspection do not resolve the issue, professional board-level diagnosis or replacement is recommended.
