Hi, my primsa 24se combi boiler i bought in around 1997 runs, but funny thing is it continues the flame after i turn off my hot water tap. I somtimes have to switch it off manual to prevent it from running. ive also noticed that sometimes it appears to be ok for a while if i switch it off at the mains power and leave it powered off over night. next day it will work of but eventully to problem will return. any suggestions to what would cause that fault?
cheers.
cheers.
