Symptoms

KitchenAid dishwasher not draining, water in tub, 7-1 error code

Common Causes

Clogged filter and sump
Drain hose blocked or kinked
Faulty drain pump

How to Fix

1 Clean the filter assembly at the tub bottom
2 Inspect and straighten drain hose
3 Ensure drain hose has a high loop under the sink
4 Replace drain pump if all else fails

Tools You'll Need

Pliers Soft Brush Towels / Bucket Flashlight

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

7-1 is generated when the CCU activates the drain pump but the pressure switch or level sensor does not confirm drainage within the maximum drain time. This mirrors the Whirlpool F8 fault code on the shared platform.

Is It Safe to Keep Using?

Fix same day. Standing water prevents safe reuse and encourages mold.

Technician's Pro Tip

KitchenAid dishwashers draining into a garbage disposal need the disposal inlet to be clear. Run the garbage disposal for 30 seconds before starting the dishwasher — if disposal residue is blocking the inlet, this clears it and prevents 7-1 errors.
