What it is
The Cable Tree X20 is a Viessmann wiring harness assembly, supplied under part number 7828981. It routes and connects the electrical cabling between components inside Vitodens 100-W gas boilers. It is a service part intended for fitting by a competent heating engineer.
Signs this part needs replacing
- Boiler fails to power up or intermittent electrical faults traced to the wiring harness
- Fault codes or lockouts linked to a broken or interrupted connection in the loom
- Visible damage to the cable tree, such as chafed, burnt or brittle wiring
- Loose, corroded or heat-damaged plugs and terminals on the harness
- A connector or retaining clip on the cable tree has been broken during previous service work
Before you order
- Confirm the boiler model is a Vitodens 100-W WB1B or WB1C, as listed in the fitment above
- Check the appliance serial number against the list to confirm the correct variant
- Inspect the existing harness and connectors to verify the fault lies with the cable tree rather than a separate component
