Checking current to electric shower

    I have a 9Kw electric shower which has just stopped working (after I had switched it off at the consumer unit, don't know if that's just a coincidence).

    The light on the pull switch is also not coming on and I want to check whether the issue is with the connection/switch or with the shower. The light that's not coming on may just have blown.

    I wanted to ask whether it is possible/safe to check the current at the pull switch with a multimeter. Want to be sure because of the high currents involved.

    I'd be grateful for any advice

    Why did you switch it off?

    There are two electric showers upstairs, and I had to replace one. The consumer unit didn't indicate which was which so I just turned both off.

    When you replaced it you might of touched some wires together and tripped the rcd by mistake (it can trip when neutral and earth touch), double check the consumer unit.

    Have checked it - everything is on at the consumer unit, nothing tripped

    You can check with a multimeter but I'm not gonna advise you on this I got In trouble last time I did that.
    You can check safely with a volt stick if you have one but never rely on it to prove dead.

    Someone will probably be along soon with a better solution maybe, otherwise you might need a sparky.

    Bit of a long shot as you have 2 x electric showers you dont have a priority board anywhere do you that would stop them both working together?

    If you switch the shower that works off maybe the other will work?

    No, they're just separate circuits on the consumer unit. Tried switching the new one off but the old one still doesn't work. I think it must have just given up the ghost coincidentally at the same time I replaced the other one

    Nah. You've done something wrong.
    Test meter, check voltages.
    Ind spark and WillyEckerslike like this.
