Shower trips electrics

When the shower itself is switched on it works for a few seconds and then trips the electrics. The pull cord switch seems to be ok. All connections fine.

Could be a number of things

Below is the order I would check things

First Check your MCB it needs to be 45amp

You say you have checked the pull cord switch

It may be a faulty element in the heating tank (there are two, three in most 10kw showers) you can check them with a multi meter you should have a reading of around 12>18 ohms.

If you have power to the elements and no heat it's probably the elements, no power to the elements then it's probably a micro switch.

If you don’t have a multimeter we sell them at £10 each with a guide on how to use them for checking and testing the various parts of your shower.


Apart from helping to fix your shower, they are really useful for checking you have a power supply to appliances, for checking fuses, letting you know much power you have left in batteries

(so you know if they are dud or not) and lots of other jobs, in short they are well worth the money.

It could also be a faulty relay board.
