What it is
This is the Viessmann connection cable (harness) for the gas valve, identified by part number 7836439 and the catalogue reference "Gas Valve 35". It is the wiring link between the gas valve and the boiler control on Viessmann Vitodens 100-W appliances. It is supplied as a single electrical connection lead for that valve circuit.
Signs this part needs replacing
- Gas valve does not operate and the boiler fails to fire, with the fault traced to the valve wiring rather than the valve itself
- Visible damage to the cable insulation, such as chafing, scorching or exposed conductors
- Corroded or loose terminals at the gas valve or control board plug, causing intermittent operation
- Continuity fault on the gas valve supply lead confirmed with a meter
- Fault code or lockout recurring after the gas valve and control connections are disturbed
Before you order
- Confirm the boiler model and serial number against the fit list above before ordering
- Check the part number on any existing cable or the boiler's wiring diagram to confirm 7836439 is the correct lead
- Inspect the gas valve plug and control board socket for damage that would also need attention
- Isolate the appliance electrically and close the gas supply before any work on the gas valve circuit
