Bosch dishwasher error codes and troubleshooting

This is the index of Bosch dishwasher error-code guides, one page per code as it appears on the display. Each page gives what Bosch says the code means, ranks the causes by likelihood, lists the checks Bosch expects an owner to do, and marks where Bosch's instructions end and a technician's begin.

Because several Bosch codes are covered, each code page ends with the Bosch codes most closely related to it and with the brand-neutral dishwasher guide for the same symptom. A page about a drain code, for example, links the other drain codes and the drain guide.

Bosch dishwasher guides

  • Bosch dishwasher E01 error On a Bosch dishwasher, error code E01 (also shown as E:01) means there is a heat pump motor circuit fault at the main control board, per Bosch's own support page; this is a control-board/circuit fault, not simply a failed heating element.
  • Bosch dishwasher E09 error (also written F09) On a Bosch dishwasher, error code E09 (also shown as E-09) signals an internal heater fault: Bosch's own US support text calls it a 'heat pump internal heater fault/error', meaning the appliance is not heating wash water correctly.
  • Bosch dishwasher E15 error On a Bosch (or Siemens) dishwasher, error code E15 means the leak-protection safety switch has detected water in the base of the appliance and the leakage protection system has activated.
  • Bosch dishwasher E22 error On a Bosch (or Siemens) dishwasher, error code E22 (also shown as E-22 or E:22) means water is remaining in the sump because the dishwasher cannot drain properly.
  • Bosch dishwasher E24 error On a Bosch (or Siemens) dishwasher, error code E24, also displayed as E-24, means the dishwasher cannot drain properly, most often because the drain pump is blocked or its cover is loose.
  • Bosch dishwasher E25 error On a Bosch (or Siemens) dishwasher, error code E25, also displayed as E-25, means the drain pump is blocked or the drain pump cover is loose or missing, which iFixit frames more broadly as the drain path being restricted.
