Hi today my electric shower suddenly cut out while in use. I got out and checked the isolator switch which is on the bedroom wall and the switch which is chrome looking was very hot. The shower is a triton electric shower. It has been installed for about 4 years and we have never had a problem before. Any one got any idea what could be causing this? I have no idea if this is a fault with the shower or with the isolation switch. Any advice would be much appreciated. We are in process of selling our house and need to sort this ASAP and as cost effectively as possible. Thanks.
