KitchenAid models: KitchenAid dishwashers share the Whirlpool platform. Most models have a manual filter assembly under the lower spray arm. Models with the ProScrub option have 40 additional spray nozzles on the lower rack; ensure the rotating satellite arm on the ProWash zone is also free of limescale blockages.
Common causes
- Water has entered the base tray from a leaking internal hose, pump seal, or door seal
- Spray arm hose connection leaking inside the machine
- Tub-to-pump seal deteriorated
Step-by-step fix
- Tilt the dishwasher forward 45° on old towels to drain the base tray — this resets the float and allows the machine to try to pump out.
- Run a short drain cycle.
- After draining, inspect under and inside for the leak source before running a full wash.
- Common locations: door seal, circulation pump seal, and the hose from the pump to the spray arm.
