What the 8-1 error means
The 8-1 error code indicates that your KitchenAid dishwasher is experiencing difficulty draining water from the tub. The control board has detected that the drain cycle is taking longer than the programmed time limit. This typically means water is pooling at the bottom of the dishwasher due to a blockage in the drain path, a kinked drain hose, or a failing drain pump.
Common causes
- Clogged drain filter or sump area with food debris and grease
- Blocked or kinked drain hose preventing proper water flow
- Clogged garbage disposal or sink drain causing backflow
- Faulty or worn drain pump unable to remove water efficiently
- Air gap or drain connection blockage at the sink
- Foreign objects like broken glass, labels, or utensils blocking the drain path
How to fix the 8-1 error
- Clean the drain filter and sump — Turn off the dishwasher and remove the bottom rack. Unscrew and lift out the cylindrical filter assembly. Remove any food debris, then check the sump area beneath for standing water or objects. Wipe clean and reinstall the filter.
- Check the drain hose — Pull the dishwasher out slightly and locate the drain hose connected to the back. Ensure it's not kinked, crushed, or positioned too high. The drain hose should have a high loop but not exceed 36 inches from the floor. Disconnect and flush the hose if you suspect internal blockages.
- Clear the garbage disposal and air gap — If your dishwasher drains through a garbage disposal, run it for 15 seconds to clear any blockages. Check the air gap (small chrome cylinder near the faucet) by removing the cap and cleaning any debris inside.
- Inspect the drain pump — Access the drain pump under the dishwasher (consult your manual). Check for debris wrapped around the impeller. Manually rotate the impeller to ensure it moves freely. If the pump is damaged or makes unusual noises, it may need replacement.
- Test the drain pump electrically — Disconnect power, then use a multimeter to test the drain pump for continuity (should read 40-60 ohms). If there's no continuity or the pump hums but doesn't run, replace the drain pump assembly.
- Reset and test the dishwasher — After addressing potential blockages, close the door and press Cancel/Drain to clear the error. Run a short rinse cycle to verify proper draining. If the error persists, the control board or wiring may need professional inspection.
FAQ
Can I still use my KitchenAid dishwasher with the 8-1 error code?
No, the dishwasher won't complete cycles with this error. It will stop mid-cycle when it detects slow draining. You need to resolve the drainage issue before normal operation can resume.
How often should I clean my dishwasher filter to prevent the 8-1 error?
Clean your dishwasher filter at least once a month, or more frequently if you notice food particles after cycles. Regular maintenance prevents clogs that trigger drainage errors and keeps your dishwasher running efficiently.
Will the 8-1 error clear itself if I just wait?
No, the error won't resolve on its own. The underlying drainage problem must be fixed. You can try running a Cancel/Drain cycle, but if the blockage remains, the error will return during the next wash cycle.
