Possible Causes
Loose power connections at junction box, Incorrect line voltage, Failed main control board, Shorted component drawing down power
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before opening the junction box or accessing the control board.
- Check junction box: Remove the toe-kick and open the electrical junction box. Verify wire nuts are tight and no wires are burned or loose.
- Verify voltage: With a qualified person and proper meter, confirm 120 VAC at the dishwasher junction box.
- Inspect control board: Access the main control (usually in a metal housing under the tub). Look for burned components or discoloration. Replace the GE Café main control board if damaged.
- Component isolation: If F7 recurs, disconnect non-essential loads (heater, pumps) one at a time to identify a shorted component that may be overloading the board.
