Schematic illustration of a typical dishwasher — not your exact model.

Before you start — unplug the appliance and turn off the water supply. You'll be working near water and electrical parts, and drained water can be hot. If a step involves the pump, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Cut the powerUnplug the dishwasher or switch off its breaker for 30 seconds to reset the control, then restore power.
2Clean the filterRemove the bottom filter assembly and rinse it thoroughly under running water to clear trapped food and grease.
3Check the drain hoseTrace the hose from the back of the dishwasher to the sink or disposer and remove any kinks, pinches, or clogs.
4Clear the disposer/knockoutIf connected to a garbage disposer, run it to clear debris and confirm the knockout plug was removed on new installations.
5Check the air gapIf an air gap is installed on the counter, remove the cap and clean out any buildup.
6Use correct detergentUse only automatic dishwasher detergent; if the pump still won't clear water, have the drain pump inspected.
