boiler repair - gas valve wiring from PCB
clueless_but_curious
Posts: 92 Forumite
Hello gas engineers!
I have a Baxi combi 105 HE. Long story (on a previous thread) but I got a new wiring harness, BAXI part no. 248216
My issue is that the plugs on the new harness for the black cables (A5 black cable 9 and 10) from the PCB to gas valve are different to what is currently in place.
I don't seem to be able to remove the current plug, but I am being careful not to pull it too hard and break something. First two pictures are my boiler. Last picture is taken from Youtube and is the same type of plug on the new harness (highlighted green)
Any advice how I remove the old plug correctly and get the new plug on?
