What it is
This is the Viessmann condensate hose, 400 mm, listed under part number 7829788. It is a flexible hose used within the condensate trap assembly of Viessmann Vitodens 100-W WB1B and WB1BC boilers, carrying condensate away from the trap to the drainage point. The 400 mm length suits the routing within these appliance families.
Signs this part needs replacing
- Water pooling or damp around the condensate trap or boiler base.
- Visible cracks, hardening or perishing of the hose material.
- Scale or sludge build-up inside the hose restricting condensate flow.
- Boiler locking out or faulting because condensate cannot drain away.
- Hose pulled loose or kinked at its connection points.
Before you order
- Confirm the boiler model and serial number against the fit list above.
- Check the existing hose length and routing to confirm 400 mm is suitable.
- Inspect the trap body and connections for damage that may also need attention.
- Verify the part number 7829788 against the appliance documentation.
