Shower not working

shamc

Hi

My electric shower stopped producing hot water a couple of mornings ago. I noticed the RCD had tripped. Having reset this, the red light on the switch comes only but only luke warm water comes out. Eventually, it gets cold.

What should I do. Replace the entire shower unit or just a part. I'm wondering whether the problem is with the thermostat.

I'm not a technical person so any advice is appreciated.

Thank you

for what its worth change the whole lot
make sureyou get the correct kw for the cable though

Thanks

Silly question, I know, but how do I find the kw for the cable?
Should it be on the rcd unit?
Can I do this job myself or should I bring in an electrician/plumber.

Thanks for your help

It should say what the kw is on the shower you've already got, eg 8, 8.5, 9. Just get the same again.

It's not difficult to change, you just need a bit of common sense, but always best to get someone qualified to do it if you're unsure.

The RCD tripping is a serious problem. It could be the heater element has broken down or there could be something else causing an imbalance to earth fault.

You should call a competant electrician to check it out for you.

The rcd tripped originally but having reset it, it's ok. Just no hot water.

usually if the cable in the shower is very chunky its prob 10mm if it looks more like abit bigger than the cable in the sockets then its 6mm
i fit showers all the time and even though they say you can fit upto a 9.5kw shower on 6mm dependant on run and how installed i do not fit more than a 7.5kw one on 6mm as ive seen the problems bigger ones can cause
unless your house is faily new or youve had it rewired you will prob only have 6mm
