galaxy 4000 si. Low pressure light stays on.

The low pressure light now stays on and I can't therefore have a hot shower. The cold setting works fine and the water seems to flow well then, but if I change the setting to hot or warm the light comes on and no hot water! I have cleaned the shower head and hose, but no improvement, is there anything else I can try or do I need a new shower?

I think you may have a faulty Thermal Cut Out

A faulty TCO will have no continuity across the two terminals (The black thing on top of the heating tank)

Therefore a good TCO will have power at both connections and a faulty TCO will have power at only one.

(The function of the TCO is, if the water over heats it cuts the power off to the elements)

See Video.
