My Diswasher stopped working a short while ago mid cycle, loked inside & found drain sump full of water & none in salt reservoir, cleared it put back some water & re-started,Neither the intake or outlet appear fouled. I now have no display symbols at all & although the dishwasher is cycling in some way, when the door is closed it giives a single beep, the arms do not spin, and there is no water circulating.
