What should I do if water remains in the tub and the dishwasher won't drain?

Verify the cycle has completed by checking the green light is on. If the dishwasher is connected to a food waste disposer, ensure the knockout plug has been removed from the disposer inlet. Check for kinks in the drain hose and food obstructions in the drain or disposer, and verify your house fuse or circuit breaker has not tripped.
