    Hi. I have recently replaced the flow switch on my boiler as it was spraying water everywhere. A further consequence of this was that the PCB was also soaked so this was replaced too.

    Problem now is that when hot water is run it goes hot then cold back to hot 3 or 4 times.

    I didn't have this problem before replacing the flow switch and PCB. Can anyone give me advice please 😀

    Are you sure the orientation of the flow switch is correct?

    Hi, thanks for advice. I didn't know that the switch could be fitted differently.
    Do I rotate it 180 degrees? It is facing up, I am assuming you don't mean putting it upside down. Just rotating?
