Default Re: hot water cutting out! performa 28

is this the performs 28 i??
re diaphragm - if the rubber is any way deteriorated no mater how minor it could be enough to fluctuate the pin which hits the micro switch there may even be a tiny hole on it!!

my best bet would be to change the hot water ntc and then see how you go. then maybe think about replacement diaphragm if you don't want to get an engineer out.
