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. E24 traces the drain path from filter to hose to the disposal connection, and the code reads the same whichever point is restricted — which is why it does not identify the part on its own.
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. Bosch lists the same drain-path causes for E25 as for E22 and E24 — a blocked filter, a blocked pump or loose pump cover, a kinked drain hose, or a clogged air gap — so a technician tests the pump and the whole drain path before replacing anything.
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. Clearing the code without finding the leak only brings it back.
Bosch defines E09 as a fault in the heat pump's internal heater — the heater built into the dishwasher's wash pump — so the dishwasher can't heat water for washing and drying. The heater is a replaceable part.
E22 signals a blocked filter or restricted drainage path. E22 begins at the filter and sump, and a code that keeps coming back points to a partial drain-hose obstruction downstream rather than anything at the filter.
A code that keeps returning points deeper — a failing drain pump, a control board fault, or a wiring issue. That is when a technician should read the stored fault history and test the affected components rather than guessing at parts.
What the symptom tells you
- Filter assembly: the first stage of the drain path, and the most common origin of E24, E25 and E22 — but a filter that re-clogs quickly means the real restriction is downstream.
- The drain path: E24 and E25 follow the water from filter to hose to pump to the under-sink connection. A kink, a high loop, or a blocked air gap produces the same code as a failed pump — which is why the code alone does not identify the part that needs replacing.
- Drain pump (E25): broken glass and hard debris reaching the impeller is a frequent cause — and the reason a pump that still runs can stop moving water.
- E15 and the base pan: E15 means the float switch in the base has detected water. The leak that put it there can be a door seal, a hose fitting, the pump housing, or the tub itself — and tipping a machine that still holds water risks spilling it into the control electronics, turning a hose repair into a board replacement.
If an E15, E24, E25, or other Bosch code keeps coming back, 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. The filter is the first stage of the drain path, so E24 often starts there — but a filter that reloads quickly means the restriction sits further down the line.
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. A technician clears or replaces the pump and checks the whole drain path, because Bosch lists the same causes for E25 as for E22 and E24.
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.
What does clearing a Bosch error code involve?
A Bosch error code identifies a symptom, not a failed part — E24, E25 and E22 all point at the drain path, but the actual fault may be the filter assembly, the drain hose, the air gap, or the pump itself. A technician reads the stored fault history through service mode, which shows how often the code has recurred and what preceded it, then repairs the component that is actually failing. Codes such as E15 (leak detected) and E09 (heater circuit) should not be reset and re-run. SAVA services all Bosch dishwashers across Chicago and the North Shore — $79 service call fee, credited toward the repair.
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.
