The overheat light will not go off and the shower is just giving out cold water. how can i fix it? The power light is on, Full Heat light off, Half Heat light off.
The overheat light does go out if set to Cold (it has cold, half heat, full heat settings). I've noted that there seems to be no difference in the water flow.
Thanks in advance.

you need to replace the thermal cut out, it sits on top of the water tank held down by two nuts. this problem is usually down to the water flow not being sufficient.
