E15 on a Bosch dishwasher means the anti-flood base sensor has tripped. Water has collected in the base pan and lifted the float, so the dishwasher shuts down to stop a leak before it reaches the floor.
The fix is to find the leak source, often a failed hose, seal, or gasket, replace it, dry the base, and reset the protection. Tilting the unit to drain the base is part of clearing the code.
Symptom and Error Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
E15 | Base leak, anti-flood float active | Find the leak, replace the part, reset |
E24 | Drain blockage | Clear the filter, hose, and pump |
E22 | Filter or check-valve fault | Clean the filter, test the pump |
What We Check
- Dishwasher E15 leak code with water in the base
- E24 drainage fault leaving standing water
- E22 code with dirty water not clearing
- E09 fault with dishes not getting hot or dry
E15 is a protective shutdown, so the dishwasher is doing its job. Prompt service finds the actual leak instead of just resetting the code, which would otherwise return.

When to Call a Technician
