What this evidence points to

Locate when and where the leak starts before opening panels.

Error-code meanings and procedures can vary by exact model and revision. Confirm against the model-specific manual.

Bosch context that changes the path

Terminology
Bosch E15 generally concerns water protection; E24 concerns the drain path, but exact procedures depend on E-Nr.
Model detail
Capture both the E-Nr and revision from the door-edge rating plate.
Diagnostic order
For E24, separate filter, pump-area and hose restrictions; for E15, locate and stop leakage before resetting anything.
Safety boundary
An active base leak requires power and water isolation.

Frequently asked questions

Should I replace a part based only on an error code?

No. A code identifies a detected condition, not necessarily the failed component. Rule out safe, inexpensive causes and confirm the exact model.

Why ask what I already tried?

The best next action changes when earlier checks fail. The engine removes repeated actions and applies prerequisite rules before ranking what remains.

Are success rates verified?

Every rate shows its denominator. Photo, receipt, invoice, technician and follow-up verification remain separate signals; none converts a small sample into high confidence.
