KitchenAid Dishwasher Standing Water in Bottom — What’s Happening
A small amount of standing water in the filter area at the bottom of your KitchenAid dishwasher is actually normal. KitchenAid designs this to keep the seals from drying out, and the water drains out at the start of the next cycle. Water left in the tub after a complete cycle, however, points to a drainage problem.
The most common culprits are a clogged filter, debris in the sump, a blocked drain hose, or a jammed garbage disposal inlet. If your dishwasher is not filling and shows code 8-1, that is an inlet or water-supply fault, not a drain symptom. This guide addresses standing water after the cycle has finished, which means something is preventing the dishwasher from draining properly.
Most Likely Causes
- Clogged filter or soil trap Food debris and grease build up in the upper and lower filters, blocking water from reaching the drain pump.
- Blocked drain hose Kinks, food particles, or incorrect routing prevent water from leaving the tub.
- Garbage disposal or air gap blockage If the dishwasher drains into a disposal, a clogged knockout plug or disposal inlet will back water into the tub.
- Faulty drain pump or motor The pump fails to run or has lost power, leaving water sitting in the bottom.
- Jammed drain valve or bracket Debris or a broken valve bracket prevents the drain path from opening fully.
- Improper drain hose loop height If the loop is below 20 inches above the floor, siphoning or backflow can leave water in the tub.
How to Diagnose and Fix
- Power off the dishwasher at the breaker before any service work.
- Remove standing water with a cup, sponge, turkey baster, or wet/dry vacuum so you can inspect the drain area.
- Pull out and rinse both the upper and lower filters under running water to remove all food debris and grease buildup.
- Check the drain path by inspecting the garbage disposal inlet (clear any knockout plug if newly installed), the air gap cylinder if present, and the drain hose for kinks or clogs.
- Verify the drain hose is looped at least 20 inches above the floor or subfloor to prevent siphoning.
- Listen for the drain pump during a drain cycle. If the pump does not run, check for power at the pump and test the pump itself for continuity and blockage.
- If the float or inlet side is suspect (usually only when code 8-1 is present), confirm the float moves freely and the water supply valve is fully open.
- Replace the faulty component identified by the checks above, reassemble filters and hoses, and run a test cycle.

When to Call a Pro
Call a pro if you have verified the filters and drain hose are clear but water still remains after a cycle, or if you are uncomfortable testing the drain pump for power and continuity. A technician can isolate whether the fault is in the pump motor, the control board, or a wiring issue. Any work involving the pump or control board also requires safe disconnection of water and electrical supply, so professional service is the safest route if you are not experienced with appliance electrical diagnostics.
