How can I effectively clean a pool of water in my dishwasher?

To effectively clean a pool of water in your dishwasher, first remove any debris or food particles from the bottom of the dishwasher. Then, check and clean the filter and spray arms to ensure proper water flow. Run a cleaning cycle with a dishwasher cleaner or a mixture of vinegar and baking soda to remove any buildup or odors. Regularly maintain and clean your dishwasher to prevent future pooling of water.
