Question

Over the weekend my drains backed up into the dishwasher. After cleaning the drains I ran the dishwasher 3 times. Under the screen there is still about an inch of water. I never noticed this before because I never removed the screen before. Can you tell me if this is normal or is there a problem with the dishwasher. The water in the little area below the screen is clean.
