Bosch Dishwasher Error Code E15
Use this page when the dishwasher shows E15 and you need a practical first-pass diagnosis. The goal is not to drown the user in article text, but to explain the warning clearly, list the safest first checks, and draw a clean line where DIY should stop.
What E15 usually means
On Bosch dishwashers, E15 is commonly associated with leak detection or water collecting in the base area. The machine may stop the cycle, show a warning, or keep the drain pump active to protect the unit.
Leak-path alert
Base tray involvement
Do not force repeated restarts
What to check first
- Look for visible water under or around the dishwasher before you reset anything.
- Think about recent events like overflow, too much detergent, or moving the unit.
- Check whether the appliance is level and not tilted forward or sideways.
- Inspect the lower filter area before attempting repeated restarts.
Most common causes
Safe first-step fix path
- 1Cancel the cycle and switch off power before you start inspecting the machine.
- 2Do not keep restarting the dishwasher if the error returns immediately after reset.
- 3Check for obvious standing water and visible external leakage around the base.
- 4Inspect filters and the lower chamber for anything that could have caused splashing or poor draining.
- 5If the appliance was over-foaming, give the lower area time to dry before another test.
When to stop DIY
Move to service-level diagnosis if E15 comes back immediately.
Stop there if water keeps collecting under the unit, if the error reappears after a careful reset, or if you cannot inspect the lower area safely without pulling the appliance out.
Questions this page should absorb
It usually signals a leak-detection state or water collected in the base area.
Only after the likely water or overflow cause is checked. Immediate repeat alerts should not be ignored.
No. Overflow, foam, or trapped water can sometimes trigger the same warning path.
