What it is
The ignition electrode 7823350 is a Viessmann component used on the Vitodens 343-F Ws4A boiler. It sits at the burner and provides the high-voltage spark that ignites the gas at start-up. The electrode is a serviceable item and is replaced when the spark weakens or the ceramic and tip degrade.
Signs this part needs replacing
- The boiler fails to light and locks out on an ignition fault
- No spark is visible at the electrode when the boiler attempts to fire
- The ceramic insulator is cracked, or the electrode tip is eroded, burnt or heavily sooted
- The electrode gap has opened up or the tip is distorted
- Ignition is intermittent, with the boiler lighting on some attempts and failing on others
Before you order
- Confirm the appliance model is Vitodens 343-F Ws4A
- Check the serial number on the appliance data badge against the fitment listed here
- Verify the existing electrode part number before removal where it is still legible
- Inspect the ignition lead and burner earth path at the same time, as poor ignition can also come from these
