Siemens Washing Machine Error Codes — What They Mean
A blinking error code on your Siemens washing machine usually points to a specific fault — drainage, door lock, water inlet, motor or electronics. This guide lists the most common Siemens front-load and fully-automatic error codes seen in Mumbai homes, what each code means, and whether it's something you can safely check yourself before calling a technician.
If you're unsure, don't force a wash cycle — unplug the machine and call us on +91 98338 75771.
| Code | What it means | What to do |
|---|---|---|
| E18 / F18 | Drainage problem — the machine cannot pump out water within the expected time. | Check the drain filter and drain hose for blockages. If clear, the drain pump likely needs service. |
| F16 | Door not closed / locked correctly. | Re-open and firmly close the door. If it persists, the door lock (interlock) may be faulty. |
| F17 | Water inlet timeout — machine is not receiving water in time. | Check the tap is open and inlet hose/filter isn't clogged. Low water pressure can also trigger this. |
| F21 | Motor / drive fault — the drum isn't spinning correctly. | Usually needs a technician: worn carbon brushes, tacho sensor or control module. |
| F23 | Aquastop activated — water leak detected in the base tray. | Turn off the tap and unplug the machine. A technician needs to locate the leak before further use. |
| F25 | Aquasensor / turbidity sensor fault — the machine can't judge rinse water clarity. | The sensor typically needs cleaning or replacement by a technician. |
| F27 | Pressure sensor fault — incorrect water-level readings. | Requires diagnosis of the pressure switch and its hose. |
| F29 | No water flow detected during fill. | Check the tap and inlet filter first; otherwise the flowmeter or inlet valve needs service. |
| F34 | Door lock did not engage. | The door interlock assembly usually needs replacement. |
| F36 / F37 / F38 | Door lock circuit fault. | Technician replacement of the door lock module. |
| F43 | Motor is not turning as expected. | May indicate a jammed drum, foreign object, or motor/tacho fault — stop use and call a technician. |
| F57 / F59 / F61 / F63 | Electronic control / communication faults. | Control board diagnosis required. |
When to call a technician
Drainage (E18/F18) and inlet (F17/F29) errors are often solved by clearing filters and checking hoses. Door-lock, motor, aquastop and control-board errors (F21, F23, F34, F43, F57+) need a trained technician with genuine Siemens spare parts — attempting these repairs yourself risks voiding your warranty and further damage.
Our Mumbai technicians carry diagnostic tools and genuine spare parts, and every installed part is covered by a 1+ year warranty.
