I have a problem with the water temperature at the moment, it used to sit just under 90 all the time. Now it drops off to nothing and then ocassionally will come back and read just under 90 or sometimes 70-80 - other times nothing. I appreciate it could be a dodgey connection or a faulty sensor (not sure which is kost likely) but don't know where the sensor is to have a look!!

Can anyone steer me in the right direction???

Thanks
