Gaggenau Dishwasher Error Codes Explained on a Gaggenau appliance usually traces to a sensor or control reading the panel is flagging. This guide covers how the fault presents, the parts we test first, and how we confirm the cause before any part goes in.
How Gaggenau Reports Faults
Gaggenau integrated dishwashers use E-codes that share their logic with other BSH machines, so an E15 base-pan trip, an E24 drain fault, and an E22 filter restriction behave the way they do across the group. The value of the code is that it tells you which part of the water circuit is unhappy, so you can look at the supply side or the drain side first rather than guessing.
Working Through Them
For E15 we find and stop the leak, then reset the float. For E24 and E22 we clear the filter, sump, and hose and confirm the drain pump. Because these units are built into fine cabinetry, we protect the surround and work cleanly. model-specific Gaggenau parts go in only where a component has actually failed, confirmed by a full test cycle.
| Code | What It Means | What We Check |
|---|---|---|
E15 | Water in base, float tripped | Leak source and float |
E24 | Drain blocked or slow | Filter, hose, and pump |
E22 | Filter restriction | Filter and sump |
