Yes, a properly functioning residential dishwasher is designed to drain completely at the conclusion of every wash, rinse, and drying phase, leaving the bottom sump basin entirely free of standing wastewater (though a very thin trace layer of moisture inside the filter well is normal). If standing water pools in the tub after a cycle finishes, it indicates an obstruction in the filter, a kinked drain hose, or a mechanical pump failure. You can troubleshoot drainage systems easily. You can verify normal appliance function when observing the dishwasher complete a wash program and leave the stainless steel tub completely empty confirms that wastewater is evacuating correctly.
