What the Error Code Means
The control board detected water in the leak tray at the bottom of the dishwasher and stopped the program to prevent electrical issues.
It is a protective alert rather than a detailed diagnosis, so the source can range from simple splash-over to a larger leak.
Common Symptoms You May Notice
- Cycle stops early and the drain pump may keep running.
- The display flashes E15 or shows a tap-and-basin icon.
- You may notice a damp smell or a small amount of water beneath the unit.
Most Common Causes (From Least to Most Serious)
- Door gasket not sealing fully: Food debris or a worn gasket can let a small amount of water slip past the door during a cycle.
- Detergent or loading issue: Using too much detergent or blocking the spray arms can create excess suds or spray that spills into the leak tray.
- Float or leak tray moisture: Residual water from a previous spill or a slow seep can lift the safety float and trigger the code.
Safe Things You Can Check Yourself
- Power cycle the dishwasher: turn it off at the control panel, wait a full minute, and turn it back on to see if the alert clears.
- Inspect the door gasket for visible debris, wipe it with a damp cloth, and make sure no utensils or racks are pressing against the seal.
- Look for obvious water on the floor around the dishwasher without removing panels; dry any small puddles you can reach safely.
If at any point this feels unsafe or unclear, stop and contact a professional.
When to Stop and Call for Service
- The E15 code returns immediately after a reset or every time you start a cycle.
- You see continuous water collecting under or around the dishwasher.
- You smell burning or notice tripped breakers—stop using the appliance and call a professional right away.
Typical Repair Cost Range
