Please help Halstead Combi Boilerproblem

[suzykev123]

Hi Guys

I am hoping someone may be able to help me with my boiler trouble. I have got a Halstead Ace High App No 47 333 16 Combi boiler. The Water pressure keeps going down and needs topping up 2-3 times per week i have searched every where for the leak but can not find one but my main problem is for the last couple of days the hot water is not working. There does not seem to be any problem with the heating side.

ya prob need the ex-vessel pumping up and poss a new prv/aav (causing the loss of sys pressure)
a new diaphragm and the tubes to the differential valve cleaning (most likely cause for the boiler not firing for dhw)

what ya like at diy?

Look at "Boler Pressure Problems" in the FAQ for xome general info.
CHeck the pressure relief pipe which goes through the wall.
If the water desn't come on it's usually a duff rubber diaphragm, or a sticking diverter valve or a dicky switch on the end of the dv.
