No hot water

[tvman]

Hi, I have no hot water on my Ferroli optimax HE31C boiler. ( I am a TV engineer by trade but have managed to repair my boilers in the past with the help of forums.).The heating works fine.
I suspect that the flow meter is causing the fault as if I put a meter across it there is no change or voltage drop when the water is flowing. I have also done resistive checks across it and there is no change when the water is run. I see from different entries on the forums that the diverta valve is suspect. Can anyone give me any advise, apart from the commom thred that runs through every thing I have read so far " Dont buy a ferroli boiler "
Many thanks TV MAN

could be the flow switch or relay on pcb sticking but as said usually the divertor valve sticking .back to the old cure first,give tham a tap see if they free off and arange replacement as required ,mind you,you will be replacing old parts for new substandard parts that will not last much longer

Thanks Puddle. I replaced the flow sensor which solved it. Regards Tvman
