Possible Causes
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a locking-out burner without investigating the cause. Isolate power and gas before inspection.
- Record conditions: Note when the lockouts occur (cold start, after long run, windy conditions) to help diagnosis.
- Follow ignition fault steps: Perform the checks described for ignition failure (electrodes, gas supply, ignition transformer).
- Single reset: After corrective actions, perform a single reset and observe the complete start sequence.
When to call a professional: If lockouts continue, a Weishaupt service technician should perform a full burner and control check.
