Gaggenau Error Code Guide

Shared Platform, Familiar Codes

Because Gaggenau and Bosch share engineering, a Gaggenau dishwasher reports drain, leak, and inlet faults much like a Bosch does, and its ovens report sensor and door faults in a comparable format. That is useful, because the same first checks apply. As always, the exact meaning of a code depends on the model and generation, so treat any chart as a starting point.

Dishwasher Codes

Drain-related codes point to a clogged filter, a blocked or kinked drain hose, or a failing drain pump, cleared by clearing the drain path. A leak or water-in-base code trips the safety float and shuts the machine down; that needs the leak found. An inlet or fill code points to the supply valve, the inlet hose safety valve, or the internal fill valve.

Oven Codes

Oven sensor codes mean the control cannot trust its temperature reading, so it stops heating for safety; the sensor or its wiring needs testing. A door-lock code can appear if the lock motor or switch fails, common after a self-clean cycle. Heating faults point to the element or its control. These are defined oven repairs.
