What it is
The P-TRAP is a Viessmann condensate siphon (P-trap) supplied under part number 7828289. It forms the water seal on the condensate discharge path of the appliance, holding a body of condensate that prevents flue gases escaping through the drain. It is used on the Viessmann Vitodens 100-W WB1A range.
Signs this part needs replacing
- Water leaking from the siphon body or its connections during operation
- Condensate overflowing rather than draining away
- Visible cracks, splits or distortion in the trap body
- Evidence of flue gas odour around the condensate drain point
- Blockage or debris build-up that cannot be cleared by cleaning
Before you order
- Confirm the appliance model and serial number against the fit list above
- Check the existing siphon for cracks, scale or blockage before replacing
- Verify the part number 7828289 matches the marking on the component being removed
- Isolate the appliance and allow the condensate trap to drain before work begins
