BAXI COMBI 105e cutting out problem?

The 30 light is above the symbol of a flame with a diagonal line through it. This is the lockout/flame failure light.
It suggests that the fault lies in the gas or ignition phase and therefore comes under gas regulations/ corgi registered only.
One thing you can try is to observe the ignition electrode through the inspection glass( look to the left ) and see if the spark continues right up to when it trips out.
If it does it may be a flame recognition fault, and if it doesn't it could be an electronics fault or flue stability problem.It very much depends on how long it runs for before tripping out.
This information might help the engineer you speak to to decide what parts to bring with him (or her). Sorry i cant be more precise..
