Possible Causes
Tripped household breaker, Loose power connection at Viking terminal block, Faulty door switch preventing power-up, Failed main control board
How to Fix / Troubleshooting
Safety first: Before opening any panels, turn off the breaker. Verify power is truly off with a non-contact voltage tester.
- Check breaker and outlet: Reset the kitchen circuit breaker. Confirm the outlet or junction box feeding the dishwasher has 120 VAC.
- Inspect terminal block: Remove the toe-kick and access cover to the power junction. Check for loose wire nuts, burned wires, or melted insulation. Tighten and repair as needed.
- Test door switch: If the unit has a mechanical on/off tied to the door, test the switch for continuity when the door is closed.
- Check control board power: With power on (only if you are qualified), verify that line voltage reaches the Viking main control board. If power is present but the board is unresponsive, the board is likely failed and should be replaced.
