Bosch Dishwasher Error Code E15 – What It Means & What to Do

Seeing an E15 message on your Bosch dishwasher usually means the leak safety system sensed moisture and paused the cycle to protect the machine. It is a common safeguard and not a sign of immediate danger.

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)

  1. 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.
  2. 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.
  3. 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

$150–$450 is typical for professional diagnosis and repair of leak-related dishwasher issues, depending on the source and parts required.

Costs vary by region, model, and provider. Request an estimate before approving any repair.
