Kenmore Dishwasher E08 Error Code — What It Means
The E08 error code (sometimes displayed as F8 or 8 blinks, depending on your Kenmore model and control generation) signals a drain-related fault. The dishwasher is detecting slow or failed drainage, meaning water is not leaving the tub at the expected rate. This is not a heating fault. The exact display format varies across Kenmore platforms because the brand uses different OEM manufacturers, so always verify against your model’s tech sheet if available.
Common Causes
- Clogged drain hose A kink, blockage, or restriction anywhere along the drain hose from the dishwasher to the sink, disposal, or air gap prevents water from leaving the tub.
- Blocked filter or sump area Food debris, paper labels, or other material trapped in the filter assembly or sump at the bottom of the tub stops normal drainage.
- Blocked drain path at disposal or air gap The drain hose connection to a garbage disposal knockout plug that was never removed, or a clogged air gap fitting, blocks the exit path.
- Wiring fault to the drain pump Loose, disconnected, or damaged wiring between the drain pump and the main control board interrupts the signal or power.
- Faulty drain pump If the hose, filter, and wiring are good, the pump itself may be mechanically jammed or electrically failed and unable to move water.
Step-by-Step Fix
- Disconnect power at the circuit breaker or by unplugging the unit before you begin any inspection or repair work.
- Remove the lower dish rack and inspect the filter assembly at the bottom of the tub, then unscrew or lift out the filter and sump cover, clean away all food debris, and reinstall.
- Pull the dishwasher forward and locate the drain hose running from the pump to the sink or disposal, then disconnect it at both ends and flush it with water to clear any clogs or kinks.
- Check the drain connection at the garbage disposal (confirm the knockout plug is removed) or air gap fitting, and clear any blockage at the sink drain point.
- Inspect the wiring harness at the drain pump, trace the connector back to the control board, and reseat or repair any loose or damaged terminals.
- Test the drain pump by reconnecting power and running a drain or cancel cycle, listen for pump operation, and confirm water exits the tub. If the pump does not run or move water, replace it.
- Run a full test cycle after repair to verify the E08 code clears and the dishwasher drains normally at each phase.
Parts Often Needed
| Part | Notes |
|---|---|
| Drain pump | Amazon | Match the part number on your existing pump or cross-reference by Kenmore model number. |
| Drain hose | Amazon | Universal corrugated or smooth-bore hose, typically 5/8-inch or 3/4-inch inside diameter, cut to the required length. |
| Wiring harness or connector kit | Amazon | Only if terminals are burned or broken. Source from the OEM or a Kenmore parts distributor for your control board generation. |
When to Call a Pro
If you have cleared the filter, hose, and drain path and confirmed the wiring is intact but the E08 code persists, the drain pump or main control board may need diagnosis with a multimeter and schematic. A technician can perform continuity and voltage tests at the pump terminals and verify the control board is sending the correct signals. Also call a pro if you are uncomfortable working behind the dishwasher, disconnecting plumbing, or handling electrical connectors under the unit.
