The short answer: the most common Bosch dishwasher error codes are E24 and E25 (drainage faults — usually a clogged filter, blocked drain hose, or jammed drain pump) and E15 (the AquaStop flood-protection system has triggered because water reached the base pan). Most Bosch error codes point to a specific, repairable component rather than a failed machine.
The most common Bosch dishwasher error codes
E24 means the dishwasher cannot drain water. The most common causes are a clogged filter at the bottom of the tub, a blocked or kinked drain hose, or a garbage-disposal knockout plug that was never removed during installation. Clean the filter first — it clears a large share of E24 faults — then check the drain hose and disposal connection.
E25 points specifically to the drain pump. Usually a foreign object — broken glass, a fruit pit, a bone fragment — is jamming the pump impeller, or the pump cover isn't seated. Accessing and clearing the pump resolves most E25 faults; a truly failed pump needs replacement.
E15 means Bosch's AquaStop flood-protection float has detected water in the base pan and shut the dishwasher down to prevent a leak. The machine usually won't run until the base is dried and the leak source — a worn door seal, a loose hose clamp, or a cracked component — is found and repaired. Tipping the unit to drain the base often clears the code temporarily, but the leak must be fixed.
E09 indicates the flow-through heating element has failed, so the dishwasher can't heat water for the wash or dry cycle. The element is a replaceable part; this is a straightforward repair.
E22 signals a blocked filter or restricted drainage path. Cleaning the filter and clearing the sump usually resolves it. Recurring E22 often points to a partial drain-hose obstruction.
If a code returns immediately after cleaning the filter and pump, the cause is deeper — a failing drain pump, a control board fault, or a wiring issue. At that point a technician should read the stored fault history and test the affected components rather than guessing at parts.
What you can safely check yourself
- Clean the filter: Remove the lower rack, twist out the cylindrical filter at the bottom of the tub, rinse it under hot water, and reseat it. This is the #1 fix for E24, E25, and E22.
- Check the drain hose: Make sure it isn't kinked behind the unit and the under-sink connection is clear.
- Clear the drain pump (E25): With power off, remove the filter and check the pump area for glass, debris, or a foreign object.
- Dry the base (E15): If safe, gently tip the unit back to drain water from the base pan, but plan to have the leak source found and repaired.
- Run a hot rinse: After cleaning, run a short cycle to confirm the code is gone before assuming the repair held.
If an E15, E24, E25, or other Bosch code returns after cleaning, SAVA reads the stored fault history and repairs the actual cause — pump, heater, control, or leak. We stock common Bosch parts for same-day repair across Chicago and the suburbs.
📞 (773) 558-3332Common Questions
What does E24 mean on a Bosch dishwasher?
E24 is a drainage fault — the dishwasher can't drain water. The most common causes are a clogged filter, a blocked or kinked drain hose, or a garbage-disposal knockout plug left in place. Clean the filter first; it resolves a large share of E24 faults.
What does E25 mean on a Bosch dishwasher?
E25 means the drain pump is blocked or failed — usually a foreign object like broken glass jamming the pump impeller, or a pump cover that isn't seated. Clearing the pump resolves most E25 faults; a failed pump needs replacement.
What does E15 mean on a Bosch dishwasher?
E15 means the AquaStop flood-protection system detected water in the base pan and shut the dishwasher down. The unit usually won't run until the base is dried and the leak source — often a door seal or hose clamp — is repaired.
Can I fix a Bosch error code myself?
Often the first step is — cleaning the filter and clearing the drain pump resolves many E24, E25, and E22 codes. If a code returns after cleaning, or you see E15 (a leak) or E09 (heater), a technician should read the fault history and repair the actual component.
Why does my Bosch dishwasher error code keep coming back?
A recurring code after cleaning points to a deeper fault — a failing drain pump, a control board issue, or an ongoing leak (E15). The stored fault history needs to be read and the component tested, rather than repeatedly clearing the code.
