Siemens washing machine error codes
Siemens (BSH group, with Bosch and Neff) washing machines show E-number codes. E17 and E18 are the two most commonly reported by UK owners; others appear on specific model lines.
| Code | Meaning | Severity | First action |
|---|---|---|---|
| E17 | Water inlet fault | Often fixable at home | Water is not entering the machine within the expected time — supply, tap or inlet valve fault. |
| E18 | Drain fault | Often fixable at home | The machine could not drain within the expected time, so water is left in the drum. |
| E23 | Leak detected (AquaStop) | Usually fixable at home | Water has been detected in the base tray — the AquaStop protection triggered. |
| E32 | Unbalanced load | Usually fixable at home | The load could not be balanced for the spin, so spinning was reduced or cancelled. |
| E36 | Door lock fault | Often fixable at home | The door lock did not close or report closed, so the programme will not start. |
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.
