Water Remains After the Cycle
Record the error code and whether the pump can be heard before resetting the unit.
Quiet, Efficient, and Serviceable
Bosch built its reputation on quiet, efficient dishwashers with strong drying and reliable electronics. The trade-off for that efficiency is that the unit depends on clear drainage and a clean filter; when either is compromised, the anti-flood and drainage protections step in and show an E-code.
Knowing the common codes turns a confusing display into a clear next step. E15, E24, E22, and E09 each point to a specific area of the machine.
Care and the Codes You Will See
Clean the filter at the bottom of the tub regularly and keep the spray-arm holes clear, since a clogged filter is behind many drainage and cleaning complaints. Keep rinse aid topped up for proper drying, and wipe the door seal. These habits prevent most everyday problems.
For codes: E15 means water has collected in the base tray and tripped the anti-flood float, often from a small leak; E24 points to blocked drainage, usually the filter, drain hose, or pump; E22 also relates to filter and drainage restriction; and E09 points to the flow-through heating element. E15 sometimes clears after the base is dried and any leak is found, but recurring codes should be diagnosed.
Quick Reference
Dishes Remain Wet or Dirty
Note cycle choice, water temperature, detergent, spray-arm movement, and recent changes.
Leak or Moisture
Stop the cycle and identify where water first appears; do not repeatedly restart it.
Door or Control Problem
Photograph the display and describe whether the latch, panel, or controls respond.
E15 Means Water Reached the Base
An E15 code means the anti-flood float has detected water in the base tray. Tip the unit gently to drain it and look for the leak source; if it returns, have the leak traced before running the machine again.

Bosch Care FAQ
What Does E15 Mean on a Bosch Dishwasher?
E15 means water has collected in the base tray and tripped the anti-flood float. Drying the base can clear it, but the underlying small leak needs to be found so it does not return.
Why Is My Bosch Showing E24?
E24 indicates a drainage fault. The machine cannot pump water out properly, usually because of a clogged filter, a blocked or kinked drain hose, or a failing drain pump.
How Often Should I Clean the Filter?
Every week or two for most households, and more if you rinse fewer dishes before loading. A clean filter prevents most drainage codes and keeps cleaning quality high.
