What it is
The Viessmann Ignition/Ionisation Electrode is a combined spark and flame-sensing electrode for Vitodens 050-W combi boilers. It provides the ignition spark at the burner and, once combustion is established, returns an ionisation signal to the control board to confirm a flame is present. It is supplied under Viessmann part number 7841762.
Signs this part needs replacing
- Boiler attempts to fire but fails to ignite, or ignition is intermittent
- Repeated lockouts with a flame failure fault after the burner lights
- Sparking visible at the electrode but no sustained flame detection
- Electrode tip shows cracking, heavy sooting, corrosion or a widened spark gap
- Ceramic insulator damaged or tracking
Before you order
- Confirm the appliance model and serial number against the fit list above
- Match the existing electrode part number 7841762 before removal
- Inspect the electrode and its lead for damage, contamination and correct gap on refit
- Isolate the electrical supply and gas before starting work
