The sump and impeller are crucial components responsible for draining water effectively.

Disconnect the dishwasher from the power supply and locate the drain pump, which is usually situated near the filter.

Inspect the pump for any visible signs of damage, obstructions, or foreign objects.

Gently rotate the pump impeller to ensure it moves freely.
