I have just installed a new Creda Spray Spa 8.5Kw Electric Shower which won't work.
The power light does not come on. There is power on both sides of the power block in the shower which I tested with an electrician's screwdriver.
I don't think there is a problem with the water supply as I originally purchased another shower which is the type activated by a knob controlling the water flow. When the water flows the heater should come on. The water flowed through this shower but would not heat. I adjusted the water pressure + & - but to no avail. I returned this shower and got the above as a replacement.
The Creda has a "Stop/Eco/High" knob and a separate temperature knob. The water won't flow if the heat does not come on.
I don't think the PRV (pressure relief valve) has been activated because that area of the bathroom was bone dry before I fitted the pipework and remained so after completion.
The shower is on it's own circuit from the main board which has a 40A MCB, which has not tripped. There is a separate on/off switch with red neon indicator outside the bathroom. The cable is 10mm clipped to the wall/ceiling across the hall into the bathroom. The distance is approx 10/12m. The wiring is approx 25yrs old.
A pull cord isolating switch and RCD remain to be installed.
The previous shower failed with a bang. I can't remember if it was on at the time - I think not but I heard the bang. I usually turn on the shower leave it to warm up and then use it.
So. Is it possible that there is something wrong with the neutral or earth wiring? Do showers detect such problems and if it is electrical how do I go about checking and testing for faults?
Any help much appreciated.
many thanks
