Had a problem with one of hoses from pump coming off Dishwasher causing flood yesterday. Replaced same with machine on it's side and washer worked for next 3 cycles. On 4th use normal cycle seemed to start emptying but then the wash light came on but no fill. Normal cycle light flashed every second and end light once every 5 seconds or so. Does anybody know what this means and is it something that I can attempt to recify myself? Don't know if this is significant but there was a polystyrene float switch device that did not seem to have a fixed location when I reattached hose.
