If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Isolate power before removing the condensate trap. Condensate is mildly acidic; wear gloves and eye protection.
User checks:
- In freezing weather, check the external condensate pipe for ice. If frozen, thaw gently using warm (not boiling) water and lag the pipe to prevent recurrence.
- Ensure the condensate pipe has not been physically damaged or disconnected.
Engineer steps:
- Remove and clean the condensate trap/siphon, flushing out sludge and debris.
- Verify correct pipe gradient (continuous fall to the drain) and pipe size as per Vokera instructions.
- Prime the condensate trap with clean water before refitting.
After clearing, reset the appliance and observe operation. If the fault persists, have a technician check for internal leaks or flue issues.
