Baxi Boiler. Power light is on, but the boiler will not ignite. Have just changed the motorised valve and everything worked ok for a couple of days. All the controls seem to be calling for the boiler and it makes the right noises but just doesn't ignite.
What should I check in the boiler and in what order? Thanks

I had a similar problem (different boiler). If it has a fan assisted flu the fan needs to be running before the boiler will light. Faulty fans are quite a common problem.

What's the model of the boiler ?

You get different faults on different boilers, depending on whether it's,

Open flue
Fanned flue
Natural Draught

Can't really help much more until you give abit more info.
