no hot water to 1 room but ok to others

[italiancat]

all of my hot water taps work except the one in my ensuite, which will only put cold water to both the hot water tap and the shower. It is all on the same system without any extra valves etc isolating the en suite and there seems to be no problem with pressure. Hot water comes perfectly from all other taps and bath. It is a baxi boiler with a preheat function - when the preheat is on I only get hot water for 2 secs then it goes back to cold. The whole system is only 18months old . there are cold and hot pipes to sink, I have tried shutting off the cold water supply but still only get cold water from the hot tap but plenty of pressure. Can anyone help me please!!!!!! winter is coming!
