Error-code support
Bosch washing machine error codes.
The displayed code helps identify the affected system. Always match advice to the complete E-Nr because meanings and procedures can differ.
Before clearing the display: take a photo of the exact code and model label. If there is water on the floor, a burning smell or power tripping, stop using the appliance.
Frequently searched Bosch codes
| Display | General indication | Recommended response |
|---|---|---|
| E18 | Drainage time exceeded or water is not leaving correctly. | Check for an obvious filter or hose restriction only when safe; arrange diagnosis if it returns. |
| E23 | Leak protection or water detected in the base area on applicable models. | Stop the cycle, isolate the water supply where safe and arrange inspection. |
| E36 | Drainage-system or pump-related indication on applicable models. | Record the complete code and model; avoid ordering a pump without testing. |
| Door / key | Door lock, open-door, child-lock or cycle-state indication. | Do not force the handle. Confirm whether water remains in the drum. |
| Tap symbol | Water-inlet or supply problem. | Check the household tap and visible hose position, then seek diagnosis if unresolved. |
Why the model number matters
Bosch washing machines span different platforms and generations. The complete E-Nr identifies the correct technical information and replacement part.
What an error code does not prove
A drainage code does not automatically prove the drain pump needs replacement, and a leak code does not identify the source. Diagnosis should confirm the actual cause.
