What it is
The Navien 30022883E is an electrode supplied for the LCB 700 range of gas boilers. It forms part of the boiler's ignition and flame monitoring circuit, sitting in the combustion path where it detects and confirms burner operation. It is listed by the manufacturer for the 21KW LCB 700 models.
Signs this part needs replacing
- The boiler fails to light or lights intermittently, with ignition attempts cutting out.
- Repeated lockout or ignition fault codes appear on the boiler display.
- The electrode tip is visibly worn, eroded, cracked or heavily contaminated.
- The boiler fires and then drops out shortly after, as flame detection is not held.
- Insulation around the electrode shows signs of heat damage or tracking.
Before you order
- Confirm the boiler model and output match one of the LCB 700 21KW variants listed above.
- Check the existing electrode against the part number 30022883E before ordering.
- Inspect the electrode lead and its connection point, as faults there can mimic electrode failure.
- Isolate the appliance and follow the manufacturer's service instructions before fitting.
