Yesterday the dishwasher crashed through a cycle, showing the delicate and fast lights flashing. We re-started the dishwasher on a normal cycle - but nothing in the top drawer was cleaned properly. I put the dishwasher on again today with a reduced load, and have come home to find that still nothing in the top drawer is clean, yet everything in the bottom drawer is fine. Any help?? Rinse aid=fine and salt is fine.
