Ok well technically this is not so much a DIY question but hear me out!
I'm living in rented accomodation and our boiler is the aforementioned Baxi piece. We've had an ongoing fault now for over a month which is driving us insane - in short, the boiler will just not fire up. You switch it on, you hear the fan spin up and down, various things click and clunk inside and after about 4 or 5 of these attempts the fan warning light eventually comes on and is then joined by the flame warning light. You can reset it, it will try again, and the same result.
The engineer comes out, messes about with it, it works for 3 or 4 days, and then does the same again. Sometimes, if it is feeling charitable it will come on long enough to get some heat into the property and allow you to have a shower but invariably it will not - i've just spent the past 30 minutes standing in front of it waiting for it to go through its failure cycle, hit reset, and on and on. Sometimes it will misbehave for a day and then work again for a few days like nothing ever happened. So to call this an intermittent fault would not be too far wrong.
The plumber / installer says that he feels the circuit board / control board for it is at fault and should be changing it whenever they he feels like getting his behind round here to do so but does anyone have any great 'quick tips' for this boiler that we might try in the interim? I'm getting sliiiightly fed up with not being able to WASH now.
Thanks.
