had to wait 2 wks for new bladder. We asked if the radiators should be flushed but the engineer said you don't flush or put inhibitor in these. The engineer fixed it but still it wasn't quite right. He came back and said we needed a new pressure relief valve. Five minutes after he left we had to call him back as the boiler cut out, this happed 3 times more! We asked if we could get a manual for the boiler but he said that manuals are not given anymore because corgi doesn't want owners to try and fix them.Still it wasn't right. He came back and said we needed a new radiator in the boiler, he came back an The hot water is only on for about 4 seconds then it goes cold. This has been going on since november. Now my husband has put cleaner in the rads and is going to try and fix it, mentioning something about a 3 way valve. It seems to me that yes we needed a new bladder but I think we just needed the system cleaned in the first place.Anyone got any helpful advice please?
By bladder do you mean hot water diaphragm. It is not true that Corgi do not want boiler manuals given out. It is part of the regulations that a boiler manual is left with the boiler on installation. You might be able to get hold of a copy from Halstead or whoever owns them now or download a copy off the internet. However what is true is that you shouldn't be repairing them yourself. I have a feeling that these boilers can go to lock-out because the venturi is dirty and also for lots of other reasons as well so don't waste your money havoing a go at different cures. To diagnose blocked heat exchanger you could put temperature sensors on flow and return. To diagnose venturi problem another method is used. You need an experienced combi boiler engineer really not Joe cowboy.
