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

1Clean the filterRemove the bottom filter, rinse it under running water, and clear any food or glass from the sump area.
2Check the drain hoseStraighten any kinks and clear clogs in the hose between the dishwasher and the sink or disposer.
3Clear disposer and air gapIf connected to a new disposer, confirm the knockout plug was removed, and clean any air gap fitting on the sink.
4Use the right detergentRun only automatic-dishwasher detergent, since suds from dish soap can block draining.
5Power resetDisconnect power for 30 seconds, restore it, then run a cycle; call for service if the code returns.
