I have a Mira Event pumped shower using household hot water with two pole switch on wall outside bathroom. When I switch this switch on the mcb on fuseboard trips immediately. The shower valve etc hasn't been opened, i.e.no water flow and pump doesn't get a chance to come on. I have checked wiring from external switch up to shower PCB and it is fine.
Am I right in thinking that it is most likely the PCB that is at fault? Or could faulty pump or flow switch somehow cause this problem?
