How to Fix / Troubleshooting
Safety First: Unplug the washer before inspecting the cord.
- Check outlet: Plug a lamp or meter into the outlet to verify stable power. Avoid using extension cords or power strips.
- Inspect power cord: Check for cuts, burns, or loose prongs. Replace the cord if damaged.
- Dedicated circuit: Ensure the washer is on a dedicated 15–20 A circuit as recommended by GE.
- Control board: If power is stable but E78 persists, the internal power supply on the main control may be failing and the board should be replaced.
