I've had a problem with my immersion heater and I've traced back to the switch. I'm getting strange voltage readings on the supply side (around 164v). I've tested my multimeter on a known good socket and I'm getting a reading of around 216V.
If I test the bare supply wires to the switch I get 164v. If I bridge to the negative on what I assume is the cable to the immersion I get a reading of 204V.
I've included a lablelled photo below to try and show what cables I am working with.....
Does anyone know why the voltages are all over the place??
