New Mira Shower - No power

[Bigily87]

I've seen many electric showers with failed heating elements. Likely to go open circuit.
Some models have a built in thermal fuse which goes open when more current is getting drawn. Try checking after a few hrs.

I’m not good with electrics but he used a stick tho g which beeped at several points of the shower unit including where the on/off button is

absolutely useless for testing, the cover must be removed from the isolator and a load put across L& N on the switched side or better again just get it replaced.

Thanks everyone. The electrician can’t come out until Thursday so it’ll be gym showers and baths until then. I just hope he can sort it because he couldn’t find any issues with the electrics when he came over on wedneday

The switch that you posted a pic of, the neutral in there will have been loose and will have overheated
