My Aqualisa power shower keeps running water , even if I turn it off at the shower head and the main isolator switch by the pump.
I am assuming there is an electrical board gone ?
most electric showers use an electric water valve similar to the ones on washing machines and these can stick in the open position so you will need to check if yours uses an electric water valve and if so change it
