We recently had a shower(electric)installed downstairs due to my wife's illness.It was installed with its own fuse board and breaker to allow the use of only one shower at a time.However the old shower upstairs doesn't give hot water anymore.The builder has said it's a problem with the shower but I disagree.It has worked twice though since the new one was installed 2 weeks ago.ANY SUGGESTIONS!. PLEASE.

I would check Circuit Breakers.

Cheers Stratmando,but excuse my ignorance.How can I go about that.Thanks again.

Should be a Big Box inside or Outside of house with Circuit Breakers that protect the wires, May be behind a picture or something.
If tripped, turn off then back on.

No joy,there was a 2nd box installed for the new shower and that seems to supercede the power for both showers.I don't think the power is getting to the old shower as in previous times when the bathroom lights used dim slightly when the shower was turned on and you would also hear the shower engaging mechanically,that I'm afraid doesn't occur anymore.

Could be a fuse inside the unit.
A Tester may be needed.

Thanks for your help Stratmando,but apparently the water pressure was quiet low in our area due to the recent cold snap(what with burst pipes and also flooding)that the local council had turned the water down in some areas,thus reducing the water pressure meaning therfore my hot water could not kick in.Oncemore thanks for your help.
