Ignition

Main flame

Customer:

you can here the ignition clicking as if it is having problem igniting it you give it a bag sometimes it just starts. Not sure about the sequence I presume it at the ignition stage.

Customer:

If you give the boiler door a bang not bag, sorry

***** ***** :

Ok, that is a lot of things that are still ok then.

***** ***** :

Perhaps a poor spark or a sticking gas valve?

***** ***** :

When was the last time it was serviced?

Customer:

Last year

***** ***** :

Perhaps worth spending £50 on a service as they can check the voltage to the pilot coil at the same time

***** ***** :

You cannot get the coils any more so it would be a gas valve swap
