Baxi Solo Electrode Kit 5132097 for Solo HE/HE A/IE Boilers

The Baxi Solo Electrode Kit 5132097 is designed to support reliable ignition and safe flame monitoring in compatible Baxi Solo boilers. Electrodes play a key role in the firing sequence: the ignition  electrode creates the spark to light the burner, while the flame sensing electrode confirms a stable flame and sends feedback to the boiler’s control board.

If your boiler is experiencing ignition lockouts, intermittent firing, flame failure faults, or cutting out, worn or carbon-coated electrodes are a common cause. Replacing the electrode kit can help restore consistent start-up performance and stable operation.

Compatibility :

• Solo HE: Solo 12 HE, Solo 15 HE, Solo 18 HE, Solo 24 HE, Solo 30 HE
• Solo HE A: Solo 12 HE A, Solo 15 HE A, Solo 18 HE A, Solo 24 HE A, Solo 30 HE A
• Solo IE: Solo 12 IE, Solo 15 IE, Solo 18 IE, Solo 24 IE, Solo 30 IE

Frequently Asked Questions (FAQ’s)

1. What does an electrode kit do in a boiler?
It supports ignition and safe running. The spark electrode ignites the burner, and the flame sensing electrode confirms the flame is present.

2. What faults can a worn electrode cause?
Ignition lockouts, delayed ignition, repeated clicking, flame failure errors, or the boiler cutting out during operation.

3. Is the flame sensing electrode the same as the ignition electrode?
No. Ignition electrodes create the spark. Flame sensing electrodes detect the flame and signal the control board to keep the gas valve open.

4. Which Baxi Solo boilers is this kit suitable for?
It fits selected Solo HE and Solo IE variants. Always match your boiler model and reference numbers before purchase to ensure correct fitment.

5. Can I fit the electrode kit myself?
For safety and compliance, fitting should be done by a qualified engineer. Incorrect installation can cause ignition issues or unsafe operation.
