How to Fix / Troubleshooting
Safety first: Gas work must be carried out by licensed personnel. Do not adjust gas pressure switches without proper training.
- Check other gas appliances: If they also fail, the issue may be with the gas supply or meter. Contact the gas supplier.
- Verify inlet pressure: A technician should measure inlet pressure at the test point on the Weishaupt gas train while the burner is running.
- Inspect gas filter: Clean or replace the gas filter element if pressure drop is excessive.
- Test pressure switch: Confirm that the low gas pressure switch closes at the correct pressure. Replace if it fails to operate correctly.
When to call a professional: Any adjustment or replacement of gas pressure switches and regulators must be done by an authorised technician.
