How to Fix / Troubleshooting

Safety: Condensate is mildly acidic; wear gloves and eye protection when handling.

  • Check external pipe: Inspect the external condensate pipe for freezing or kinks. Thaw gently with warm (not boiling) water if frozen.
  • Trap cleaning (technician preferred):
    • Isolate power.
    • Remove the condensate trap from the boiler following Junkers instructions.
    • Rinse thoroughly with clean water to remove debris and reinstall, ensuring correct seals.
  • Verify fall: Ensure the condensate pipe has continuous fall to the drain to prevent standing water and gurgling.
