Dishwasher Clogged — Drain Portable
If the filter is spotless and water still won’t drain, the clog has likely moved deeper, to the pump impeller. The impeller is a small, plastic fan that pushes water out through the drain hose. It can be jammed by a rogue shard of glass or a cherry pit.
To inspect it, you will need to remove the filter again. Shine a flashlight down into the opening. You are looking for the small, finned impeller. Sometimes, you can see a piece of debris lodged in its blades. Use a pair of long needle-nose pliers or a bent wire coat hanger to gently extract the blockage.

To clear the hose: disconnect the dishwasher from power. Place a bucket and towels under the sink. Use pliers to loosen the hose clamp where the hose connects to the garbage disposal or sink drain. Pull the hose free, and be ready for residual water to pour out. Then, disconnect the other end of the hose from the dishwasher pump (again, expect water).
