Brand new electric shower

Clint:

Brand new electric shower and nothing but cold water? Any ideas? Almost like the tco keeps going but How on a new shower?


I don’t believe the plumber/electrician changed the hose and they just reused existing one as the new one wouldn’t of fit and would have had to had drill holes on show on tiles.

I think some early (lower power) showers had a small bore hose - as they would restrict the flow rate to keep the delivery temperature up. If the new shower is higher power and doesn't regulate itself down and the old hose means that the water flow is restricted then it could well overheat and trip the thermal cutout - if that matches the symptoms. Temporarily swapping to the supplied hose might help the diagnosis.
