Bosch (BSH group, with Siemens and Neff) washing machines show E-number codes. E17 and E18 are the two most commonly reported by owners; others appear on specific model lines.
| Code | Meaning | Severity | First action |
|---|---|---|---|
| E18 | Drain fault | Usually fixable at home | The machine could not drain the water out within the expected time. |
| E17 | Water inlet fault | Usually fixable at home | The machine did not fill with water within the expected time — the inlet flow is too slow or stopped. |
| E16 | Door lock fault | Usually fixable at home | The control unit cannot confirm the door is closed and locked, so the programme will not start. |
| E02 | Motor fault | Engineer needed | The motor is not responding as expected. |
| E13 | Water leak detected | Engineer needed | Water has been detected in the base tray of the machine, which triggers the anti-flood switch. |
Safety first
Unplug before any check. Never open panels beyond the filter flap. Anything involving internal wiring, the heater or gas must go to a professional — see each code page for its "call a professional when" line.
