Kenmore Dishwasher Not Draining — What’s Happening
A Kenmore dishwasher not draining means standing water remains in the tub after the cycle finishes. This is a symptom, not a single fault code. On many Kenmore Elite and Whirlpool-built models, the diagnostic system may log a drain problem code such as 8:2, but the exact code meaning is model-specific and must be confirmed from the tech sheet inside the door or on the tub wall.
The symptom can be caused by a physical restriction in the drain path, a failed drain pump, or a control or wiring fault that prevents the pump from running. Some models also tie drain faults to float switch or diverter problems. The diagnostic sheet for your model will list the stored codes and component test procedures.
Most Likely Causes
- Clogged filter or sump area A dirty or restricted filter set is one of the most common causes of poor drain performance.
- Garbage disposal knockout plug still installed The disposal inlet knockout plug may still be in place on a new disposal, or the dishwasher drain path may be blocked at the disposal connection.
- Kinked, pinched, or clogged drain hose Hose restriction is a common failure point, especially after moving the appliance or during installation.
- Drain pump obstruction or motor failure Debris in the pump, a seized impeller, or a failed pump motor can prevent draining.
- Piston and nut assembly stuck or not sealing If the piston and nut assembly does not move freely or does not seal when down, the dishwasher may not pump out completely.
- Control board, timer, or wiring fault If the pump is good but not energized, the issue can be the control board, timer, wiring harness, or a safety input such as the float switch.
How to Diagnose and Fix
- Disconnect power at the breaker or unplug the unit before any service work.
- Confirm the symptom by checking for standing water in the tub and listening for the drain pump during the drain cycle.
- Remove and clean the filter assembly and sump area, looking for food debris, broken glass, or other obstructions.
- Inspect the drain hose for kinks, pinches, cracks, or blockage, and verify the hose-to-disposal connection is clear and the disposal knockout plug has been removed if a new disposal was installed.
- Remove the sump cover and inspect the piston and nut assembly under the sump for free movement and a proper seal in the down position.
- Check the drain pump for debris and confirm the impeller spins freely and is not jammed.
- Disconnect the drain pump and test continuity across the terminals with a multimeter (a good pump should read zero or nearly zero ohms, with no continuity to ground from a terminal to the metal housing).
- Access the tech sheet inside the door or on the tub wall, retrieve any stored fault codes, and use the diagnostic mode and circuit diagrams to test the timer or control board output and wiring to the pump if the pump tests good but is not being powered.
Parts You Might Need
| Part | Notes |
|---|---|
| Drain pump | Amazon | Replace if the impeller is seized, the motor has failed, or continuity tests show an open or shorted winding. |
| Drain hose | Amazon | Replace if kinked, cracked, or collapsed internally and cannot be cleared. |
| Piston and nut assembly | Amazon | Replace if stuck, corroded, or not sealing in the down position after cleaning. |

When to Call a Pro
Call a pro if you have cleared all drain-path obstructions and confirmed the pump has continuity but the unit still will not drain, or if the diagnostic mode shows a control or wiring fault you are not comfortable tracing. Also call if you need help interpreting the tech sheet for your specific model or if the fault code points to a float switch, diverter, or timer issue that requires component-level testing and part-number lookup.
