i have a worcester 28 cdi.when the hot water tap is turned on the the pressure on the "sealed system pressure gauge" goes up to between 3-4 bar and the flame goes out. if the hot tap is left running the "sealed system pressure" goes back down to about 1 bar and the boiler flame returns.
this happens even when the central heating is turned off.
PS
the pressure release valve has dripped for ages!
please could anyone suggest a way to Accurately fault find the problem so i dont get ripped off?
