Published 2025-08-26 · Error & Fault Codes
A Bosch dishwasher showing E15 has activated leak protection: water reached the base pan and lifted the Aquastop float. The drain pump runs and the cycle will not continue. The code is a symptom of a leak somewhere upstream, so finding and clearing that leak is the actual repair.
What We Check
Reading the sign is the start; testing confirms the part. Here is how we work this fault on Bosch:
| Code | What It Means | What We Check |
|---|---|---|
E15 | Water in the base pan, leak protection active | Locate and clear the leak, dry the base, reset |
E24 | Drainage fault, water not leaving | Clean the filter, drain hose, and pump |
How We Fix It
- A dishwasher showing E15 with water in the base pan
- Dishes coming out cold from a heater fault
- A cycle that will not start or a door that will not latch
Other Bosch codes we read on Bosch include E22 and E09. See the full list and model lines on our Bosch repair page.
Why It Matters
A dishwasher fault that leaves standing water or trips leak protection is worth handling before it reaches cabinetry or flooring. We find the underlying leak or blockage rather than only clearing the code, so the problem does not come back.
What to Have Ready When You Book
It helps to have the model number and any fault code or indicator light noted before we arrive. That lets parts needs and availability for Bosch are confirmed after diagnosis, and repair timing is scheduled accordingly.
