Question

I have a Kitchen Aid Superba KUDS24SEBS1. The inlet water pressure is good and the dishwasher fills and starts the wash cycle, however, after the initial spray of water, it seems that all of the water drains out and there is nothing left to continue the cycle and wash the dishes. It's like it's not able to fill up enough to wash the dishes.
