I have a triton sambada 8.5kw electric shower which runs off a cold feed and a 6 mm cable. Can someone advise please with some problems i'm having. When in the shower and if dishwasher or washing machine is on, the shower loses or gains temperature. Is there a fault with the shower or do I need a new one maybe with a thermostat or is it really just a case of not having these appliances on at same time as shower??? Also which one should I buy to suit my requirments if I need one at all. Many Thanks.
