KitchenAid Dishwasher F8E1 Error Code — What It Means
F8E1 means the dishwasher is draining too slowly. The control expected the water level to drop within a set time and it did not.
Most slow drains come from a clog in the filter, sump, hose, or air gap. If the path is clear and water still sits, the drain pump itself is the next suspect.
Common Causes
- Clogged filter and sump Food and grease build up in the bottom filter and sump and choke the outflow.
- Kinked or blocked drain hose A pinched or clogged drain hose slows the water leaving the unit.
- Blocked air gap or disposal A plugged air gap or a disposal with the knockout plug still in place backs water up.
- Obstructed drain pump Glass or debris jams the drain pump impeller so it cannot move water fast enough.
- Failing drain pump A weak or failing drain pump motor no longer pushes water out on time.
Step-by-Step Fix
- Disconnect power before reaching into the tub or under the unit.
- Remove and rinse the bottom filter and clear any debris from the sump.
- Check the drain hose for kinks and clear any clog along its run.
- Inspect the air gap or disposal inlet and remove blockages, including a missing disposal knockout plug.
- Access the drain pump and clear any debris caught in the impeller.
- Test the drain pump for continuity and proper operation, then replace it if it is seized or open.
- Restore power and run a cycle to confirm the tub drains fully.
Parts Often Needed
| Part | Notes |
|---|---|
| KitchenAid dishwasher drain pump | Amazon | Match the drain pump to your full model number since the impeller and mount vary. |

When to Call a Pro
If the filter, hose, air gap, and pump are all clear and the drain pump tests good but F8E1 returns, the control board may be misreading the drain. That is a good time to bring in a technician.
