Possible Causes
Corrupted control board memory, Power surge damage, Faulty main control board, Loose control board connectors
How to Fix / Troubleshooting
Safety first: Disconnect power before opening any panels.
- Hard reset: Turn off power at the breaker or wall outlet for at least 10 minutes to allow the control to fully discharge. Restore power and attempt a cycle.
- Check power quality: Ensure the dishwasher is on a stable power circuit without frequent outages or surges. Avoid sharing the circuit with heavy loads.
- Inspect control connections: If you can safely access the main control board (usually behind the front panel or under the unit), check that all harness connectors are fully seated and free of corrosion.
If F8 persists after a hard reset and connector check, the main control board is likely defective and should be replaced.
