I hope its not the PCB.. Is this a common fault..???

mmmmmmmmmmmmmmmmmmm
A little tail here.....!!
A ordered a 111793 flow switch. (think its for a 110HE)
It is not exactly the same from a pipe work point of view, but...
This one is driving me up the wall.
I have an issue with a Baxi 133HE Plus.
End result is that it goes in to fault and locks out.
I think it is heating the DHW up to an over temp state but don't let me lead you.......
OK what I can see................
Heating works fine.
Turn on...
