What it is
This is the Viessmann cable wiring harness X8/X9, supplied under part number 7822945. It is the loom that connects the X8 and X9 plug positions within the appliance wiring on Viessmann Vitodens WB3A system boilers built from 30.01.2004 onwards. It carries the internal electrical connections between those plug points and the associated components.
Signs this part needs replacing
- Intermittent or unexplained electrical faults that change when the loom is moved or the plugs are reseated
- Fault codes relating to the components served by the X8 or X9 connections
- Visible damage to the harness: chafed or split insulation, scorched or discoloured conductors, or corroded, loose or brittle plug terminals
- The boiler failing to run, or components cutting in and out, where the wiring continuity is suspect
Before you order
- Confirm the boiler model is a Vitodens WB3A system boiler and note the serial number
- Check the appliance was manufactured from 30.01.2004, as the harness is specified from this date
- Compare the plug configuration on the existing harness with the X8/X9 layout before fitting
- Verify the fault lies in the harness rather than in a component or connector served by it
