Example: after using the shower, I find the boiler still operating with no flame. The fault led’s show 60 70 flashing. The fault finding page in manual, states Fan off, but air pressure switch fails to return to off position. Is this the answer to my question
The other problem I have is led lights, in DHW mode Continuously rotate in pairs left to right across the panel but not in the C H mode
Also DHW temperature fluctuates.
We have also noticed that one radiator gets hot on occasions, any Ideas please.
PS. 2009. I changed the diverter valve and both thermistors.
2010 I changed P C B ionisation board.
After I installing P C B I noticed that the led lights in DHW mode Continuously rotate in pairs left to right across the panel, when I enquired to the supplier, they said that the new ones do this could it be an 100 pcb
