[carl c]

Hi i have gat a baxi 105he . There is hot water to all taps in the house apart from the kitchen tap with is cold . i did manage to bring the boiler on once with the tap open fully. But it used to work with tap half open... Any ideas

is it a mixer tap cold my be mixing with the hot

Think a dying dhw diaphragm can cause this, if its a mixer tap isolate the cold to the tap via the service valve and then try the tap again
