Hi All
Ocean Alpha 240 eco combi boiler keeps our place toasty warm and can heat the rads till they burn your hands. But it can run a bath unless you have the hot tap about a 1/4 - 1/2 turn maximum?
Is this a failry common fault and just some little switch thing or is likley to cost gazzillions of £s?
Many thanks.

Hi.
Thanks for the reply.
Does the diaphragm reside in the DHW flow valve?

Hi, Problem more than likely with hot water diaphram! 99 times out of 100 it is!!! first of all turn your heating off then run a hot tap and look to see if the boiler lights? if it doesnt then it'll be hot water diaphram!! it doesn't cost much (about £15-£20)
