Hi,
I attended this boiler just before Christmas to repair a no hot water situation, symptoms were no response from the boiler when hot water tap was opened.
I had a replacement flow switch on the van so I just changed it and all was well.
Customer called again a couple of days ago for same symptoms, I attended today and this time I tested the flow switch, I found 4.9 v between black and red and 2.4 v between black and yellow when tap opened so flow switch was fine.
I was then tied between the diverter valve and the PCB, I called technical and they said it is 100% the PCB, I just wanted a second opinion before I change it.
