H i Fellas,

I have a Worcester 24cdi combi boiler that has had an intermittent fault for a while now, i should explain, the boiler is in girlfriends house!
Anyway the problem is that the boiler cuts out intermittently within maybe an hour and a half of it firing up from cold, it can be reset and does fire up again but after a while it cuts out again and the cenral heating light flashes. I do know a bit about combis and went around and the first thing i found was that the pressure gauge did not have the usual permanent red needle on the face to act as a guide to the pressure, so, i operated the pressure relief valve but the pressure did not drop as expected although i could here the water being released. My girlfriend explained that she knew how to "top it up" but i wondered that she had over pressurized it by no knowing what the pressure was because the gauge didnt seem to work. The boiler is situated upstairs in the airing cupboard. So, after i had though i had drained the boiler to what i though was empty because i couldnt hear anymore water draining, i then topped it back up basically guessing at what pressure it was.
All seemed fine this morning as the boiler came on at the timer, and also this evening when my g/f returned from work but the it cut out within an hour and a half again.
Any ideas please?

p.s the boiler is 7 years old
 
Get the pressure guage repaired first. Even if not related to the fault you should always know what the system pressure is.

Other than that it seems the CH light flashing could be either ignition related or temp sensor related.

If you have the manual you could confirm this. As i think it varies the speed of flash depending on the fault.
 
hi rob thanks for your reply.
i have looked at the manual for my boiler on the worcester website, but not really sure how to follow the related flow chart. The CH light flashes slowly here is a link to the page if you could have a quick look?

and as for the pressure gauge, would the fact of it being installed have an affect on how much water could be drained from the system thus the pressure gauge not hardly dropping?
thanks

According to that a slow flash indicates 'ignition lockout'. If it's really intermittent then i'd recommend getting Worcester out. They'll do a fixed price repair and can just chuck parts in it of it's working when they arrive .

I dont really understand that :?
 
sorry rob, i meant would the fact of the boiler being installed upstairs have an effect on how much water can be drained and thus on the pressure gauge. what i mean is, could i drain it down so the pressure reads zero?
thanks
 
has anybody else got any thoughts on what the problem may be?
