Water remains in the bottom of the tub between cycles, even when the dishwasher has not been used.

Safety First: Turn off power before working under the sink or behind the dishwasher.

• Inspect drain hose routing: Ensure the hose has a high loop under the counter or is connected to an air gap to prevent backflow.
• Check disposal connection: Verify the disposal outlet is not clogged and that water flows freely when running the disposal.
• Drain standing water: Run a cancel/drain cycle to remove water from the tub.
• When to call for service: If water continues to reappear, the internal check valve or drain system may need professional repair.
