Dimplex Ax3
If when you switch off the shower at the main isolator and the shower keeps running then you have a faulty solenoid valve.

When you switch off the shower at the main isolator and the water stops running, then you have a faulty on/off switch or a faulty PCB or a micro switch that is sticking on.
So I guess you need a new solenoid valve and I don't think you need an on off switch
