HI , when i use the dishwasher, it goes through the cycle stopping at the same two points on the timer every time, the only way to stop it continually churning water around is to physically move timer switch,then when dishwasher is opened there is no steam like there used to be,items aren't hot , and not very clean as if water isn't getting hot enough,can anybody please point me in the right direction,or has anybody a wiring diagram for this model that i could have , cheers for looking and thanks in advance for any help , lee
