I have had to recently replace my immersion heater. However on the new type
thermostats that come with them they have a reset switch. The reset switch
is constantly tripping out before the tank has reached the temperature set .
I have tried a couple of new thermostats and also replaced again the whole
immersion heater (i bought one from bnq then from Screwfix). I read on the
little leaflet within that it could be some electrical fault. I am in a hard
water area (well so im told from websites ive found) so therfore bought the
following (which looks exaclty like the old one i removed)...
where do i start and what can i use to diagnose what is causing the fault.
any help really much appreciated.
