Bosch Dishwasher Error Codes: What E15, E24, and E25 Usually Mean
Bosch dishwasher error codes are useful if you know what they point to. Here are the common codes and when to stop resetting the machine.
Expert answer
Quick answer for homeowners
Bosch dishwasher error codes usually point to water, drain, leak, heating, or pump faults. E15 commonly means water in the base pan, E24 is usually a drain restriction, and E25 often points to a pump or impeller obstruction. If the same code returns after one reset, the fault needs diagnosis.
- E15 should be treated as a leak warning, not just a reset issue.
- E24 and E25 usually start with drain-path inspection.
- Repeated Bosch codes are useful diagnostic clues for a technician.

Bosch dishwasher error codes are designed to narrow the diagnostic path, but they do not always name the failed part directly. E15, E24, and E25 are the codes Orange County homeowners ask about most often, and each one needs a different response.
E15: Water in the Base Pan
E15 usually means the leak-detection float has lifted because water is in the base pan. Tilting the dishwasher may temporarily clear the code, but it does not fix the leak. The cause may be a door seal, fill valve, sump seal, drain connection, or oversudsing.
E24 and E25: Drain Problems
E24 typically points to restricted drainage, while E25 often points closer to a pump or impeller obstruction. Check the filter, sump, drain hose, and disposer connection first. If the code returns, the pump and check valve need diagnosis.
Other Bosch Codes We See
- E09 can indicate a heating-circuit issue.
- E19 can point to a dispenser or internal valve issue on some models.
- E22 often relates to filter or drainage performance.
- Repeated codes after reset usually mean the underlying fault is still present.
Resetting a Bosch dishwasher is useful once to confirm whether a fault is intermittent. If the same code comes back, the machine is protecting itself and needs diagnosis.
