Easy diagnosis on this one folks. If an inch or more water is present in the bottom after a completed cycle simply close the door and press the cycle start and press again to cancel. If the water is gone after the dishwasher completes the cancel cycle there's no problem with your pump, drain hose configuration or clogged filters. This will be a timer problem. If water remains then by all means you should check drain hose, pump, filters for proper operation.
