Possible Causes

Partially blocked flue, Incorrect flue length or configuration, Strong wind causing downdraft, Faulty flue gas sensor or pressure switch

How to Fix / Troubleshooting

Safety: Do not operate the heater if you suspect flue gas is not being safely discharged. Risk of carbon monoxide.

  • Check terminal: Inspect the external Weishaupt flue terminal for obstructions (bird nests, leaves, snow). Clear any blockage.
  • Verify flue installation: Ensure that flue sections are properly joined, supported, and sloped as per Weishaupt installation instructions. Incorrect installation can cause E13 faults.
  • Wind effects: If E13 occurs only during strong winds, consider fitting an approved terminal guard or wind shield after consulting Weishaupt documentation.
  • Sensor/switch check: A technician should test the flue gas sensor or any flue pressure switch for correct operation and replace if necessary.
