Worcester 19/24 cbi problems

[djw]

Hello, We had a Worcester 19/24 cbi Domestic gas boiler, installed in 2004. The installer (not now in business), informed us that there may be some residual air in the system, as the boiler would go into 'Lock-out' mode every now and again. He assured us that it would be OK and just to turn the temperature control dial fully anti-clockwise and then back again to reset. It has had this problem on and off now since then. Sometimes it doesn't happen for weeks. Other times it can be 4 or 5 times a day!! No-one seems able to offer much help so we have just learned to live with it! However, it now seems to have developed a further fault in that whilst the boiler is on providing heating and hot water it works for maybe 10- 15 minutes then changes to show only the 'boiler-demand' light,on and steady, but the burner refuses to re-ignite. Again, I have to reset via the temperature control dial. This happens continuously, meaning we either have a very cold house and no hot water, or I stand next to the boiler, resetting it, every time this problem occurs! We are currently trying, yet again, to find a competant engineer to look at these faults but i wondered if anyone could offer any advice so we are ahead of the game. (So to speak). Thankyou, DJW

why not contact the manufacturer

Have you tried ringing worcester?

like it'd be worth a ring. No idea what their engineers are like (although being part of Bosch I'd assume they wouldn't be crap...)

£200 WB callout seems like a lot, but it includes up to 3 parts (which are pricey). At least you know it'll be fixed properly in one visit

I have one customer who has one of these beasts and the symptoms you describe sounded familiar. I think on this one a replacement PCB (from Geoff/CET Ltd) did the trick.

However this particular boiler seems to be the runt in Worcester-Bosch's litter: it has a cast-iron heat exchanger with O-ring seals which are prone to leaking, requiring a strip-down of a large part of the boiler to replace. If you are at all inclined to replace it with a new one I'd encourage you to do so.

Yeah, I was thinking that the pcb had to be the most likely problem

Hi Art, did you ever get to the bottom of the issue please?

Hi DJW, did you ever get this issue sorted please?

like what it said in the thread, a refurb PCB would be the thing to try:

[Jpm]

Thanks John. I’ll have a look at them. New ones seem to be quite pricey at £174.

[John Rumm]

CET will do you a refurb exchange - fit the new one, and send em back the knackered one. Works out much cheaper.

Thanks for the info John.
