What Does Error E27 Mean?
The Siemens Washing Machine E27 error indicates a malfunction in the water inlet valve, primarily due to a faulty pressure sensor. This issue may prevent the machine from filling with water or cause unusual sounds during operation. If you see the E27 code, your machine may not detect the water level correctly, affecting the wash cycle's progress.
Common Symptoms:
- Machine stops and displays E27 or F27 code
- Wash cycle will not start or proceed normally
- Machine may not detect water level correctly
Possible Causes
- Pressure sensor (water level/pressure switch) fault (high)
- Pressure sensor system issues (e.g., clogged pressure tube) (medium)
How to Fix Error E27
DIY Fix Basic user checks before service
- Turn off and unplug the machine.
- Check for obvious kinks or blockages in hoses that could affect pressure sensing (e.g., pressure tube if externally accessible).
- Ensure the machine door is fully closed and latched.
- Restart the machine after a short power‑off period to see if the code clears.
Technician Only Inspect and replace pressure sensor or related components
- Verify presence of E27 code on diagnostic interface and check error logs if available.
- Inspect pressure sensor (pressure switch) and associated wiring/connectors for faults or water ingress.
- Examine pressure tube and pressure chamber for blockages or damage.
- Replace faulty pressure sensor and clear error codes.
- Test the machine through a full cycle to confirm resolution.
Parts needed: Pressure sensor (pressure switch), Pressure tube/hose, Electrical connectors/wiring harness as needed
- If the E27 error persists after basic user checks
- If you are not comfortable inspecting internal components or handling electrical parts
- If machine shows additional faults (e.g., leaks, other error codes)
