I have had a new bolier fitted but the hot water isnt working. It come on when a hot tap is turned on. It works when you do the test button but then you have central heating on to. There is know Fault coming on either.
my combi boiler fan runs for a few seconds and then knocks out the lcd fault code. the another minute later it starts the cycle again and again.

our boiler is showing f37 fault. the pressure is on zero but the landlord hasn't left maintenance instructions. how do we refill it to the right pressure?

it's supposed to come on when ypu run a tap, that's the whole point of a combi boiler, your installer should have explained it's operation
