got an ideal combi boiler that is misfiring. when the ch is on it stays on permanently until boiler is shut off at mains then other times the boiler will not ignite at all and keeps trying to fire but no joy. also the pressure keeps needing to get topped up at a rate of once a day no leak anywhere. does the expansion vessel need re charging? any help appreciated

I suspect your boiler needs a service to cure the ignition probs (possibly electrodes need replacing)
If you're losing water there must be a leak of some description, could even be heat exchanger leaking and drying out as it's heated.

DON'T
I've seen these things explode because of an unwitting diyer "having a look".
The sad truth is probably that your boiler's finished.
You're losing pressure because the heat exchanger has corroded through, and the water evaporates and goes out of the flue. Eventually the electrodes get wet and they won't fire.
It would then be beyond economic repair. You have 3 options;
Get a new boiler. Responses are pretty bad at the best of times.
Call Ideal
Call Brit Gas
for the last 2, ask about their fixed price repair schemes. Heat exchangers have gone in and out of availability. If you're lucky, one of them might still be replacing hexs.
Expect to pay about £200 - £250 unless there's an offer on, you're in the wrong postcode area, or some other lame excuse!
sorry didnt make myself clear in opening post i am an installer for bg but ant got a clue about breakdowns or fault finding. its a mates boiler went around today gave it a good clean and ignition probs are now fine.
