Frequently Asked Questions (FAQ’s)

1. What is a Baxi ignition electrode?
A burner electrode that creates the spark needed to light the boiler’s gas burner safely.

2. Is this compatible with Baxi 105 HE A Instant?
compatibility shows 105 HE A Instant GC No. 47-075-50. Match this GC number and the electrode part reference before ordering.

3. What symptoms suggest the ignition electrode is faulty?
No spark, ignition lockout, boiler firing then stopping, clicking but not lighting, or intermittent heating/hot water.

4. Will a new ignition electrode fix “no ignition” problems?
Often yes-if the root cause is a weak spark, damaged ceramic, poor electrode gap, or contamination on the electrode tip.

5. Is an ignition electrode the same as a flame sensing (ionisation) electrode?
Not always. Ignition electrodes create the spark; ionisation electrodes prove the flame signal. Some boilers use separate parts.
