What this code means
The dishwasher has detected water or a float-switch condition in the base. The drain pump may continue running as a protective response. AE and E1 descriptions can vary by model generation.
Most likely causes
- A door, tub, sump, hose or pump connection is leaking
- The dishwasher is twisted or not level, allowing water to escape the intended wash area
- Excess suds are pushing water where it should not go
- Debris, moisture or a failed base float switch is reporting a leak
Safe checks for the owner
- Turn off power at the breaker and close the dishwasher water supply.
- Inspect the floor and cabinet for active water and protect surrounding materials.
- Check that automatic dishwasher detergent—not hand dish soap—was used.
Estimated U.S. repair cost
$220–$520, depending on model, access, parts availability and local labor.
