Bosch Dishwasher Error Codes
Bosch codes usually show as E followed by two digits. Some models show F instead of E (E18 or F18), and older UK manuals print them as F:18.
Codes can vary by model
Check the model number on your dishwasher’s rating label and your manual. We only list codes we’ve checked against Bosch guidance. For anything else, use Bosch UK support.
| Code | What it means | Severity |
|---|---|---|
| E09 | The dishwasher’s heating element is defective. | Likely needs an engineer |
| E15 also F15 | The dishwasher’s water protection system has been triggered because it has detected a water leak. | Likely needs an engineer |
| E24 | The dishwasher isn’t draining properly because of a blockage. | Check carefully |
