worcester 240 combi boiler. will not start up?
The boiler was working. I turned on the hot water tap and no hot water. Looked at the boiler, You can hear a clicking noise but not starting. Had a look inside and the only thing i can see that may not be right is on the left board. Label Sg1 ...as a spark in the middle of it every it, it goes to start.
Can anyone help
Thanks Andy
