The E14 error on your Siemens Dishwasher means the flow meter sensor has detected an issue with water flow or the sensor itself has failed. This typically prevents the dishwasher from operating correctly and requires checking the water supply and internal components.
| Error code | E14 |
|---|---|
| Meaning | Flow meter sensor malfunction or water flow issue detected |
| Severity | Medium — Dishwasher will not operate until resolved |
| Time to fix | 15–45 minutes |
| Tools needed | Screwdriver, multimeter, towels |
What the E14 error means
The E14 error code indicates that your Siemens dishwasher has detected a problem with the flow meter sensor, which monitors the amount of water entering the appliance. This sensor helps ensure the correct water volume is supplied during each wash cycle. When the flow meter fails to register proper water flow, or when the sensor itself malfunctions, the dishwasher's control board triggers the E14 error and halts operation to prevent damage or poor wash performance.
Common causes
- Blocked or kinked water supply hose restricting water flow to the dishwasher
- Faulty or damaged flow meter sensor that cannot accurately detect water movement
- Low water pressure from the household supply preventing adequate flow
- Clogged inlet valve filter screen blocking water entry
- Wiring connection issues between the flow meter and control board
- Failed water inlet valve preventing water from entering the machine
How to fix the E14 error
- Check the water supply: Turn off the dishwasher and ensure the water supply tap is fully open. Inspect the inlet hose for kinks, twists, or blockages. Disconnect the hose from the back of the dishwasher and check that water flows freely from the tap. If water pressure seems low, check other taps in your home to rule out a general supply issue.
- Clean the inlet valve filter: Turn off the water supply and disconnect the inlet hose from the dishwasher. Remove the small mesh filter screen located at the inlet valve connection point and clean it thoroughly under running water to remove any debris, limescale, or sediment. Reinstall the filter and reconnect the hose securely.
- Inspect the flow meter sensor: Access the flow meter by removing the dishwasher's lower front panel or side panel (consult your manual for location). Check for visible damage, debris blocking the sensor, or loose wiring connections. Clean around the sensor carefully and ensure all connectors are firmly attached. If the sensor appears damaged or corroded, it will need replacement.
- Test the flow meter with a multimeter: With the dishwasher unplugged, disconnect the flow meter wiring harness and use a multimeter to test for continuity and proper resistance values according to your model's specifications. If readings are outside the normal range or show no continuity, the flow meter is faulty and must be replaced.
- Reset the dishwasher: After addressing any issues, reset the appliance by turning off the power at the circuit breaker for 5 minutes, then restore power. Start a new cycle to see if the error clears. If the E14 error persists after these checks, the flow meter sensor likely needs professional replacement or there may be a control board fault.
FAQ
Can I continue using my Siemens dishwasher with the E14 error showing?
No, you should not attempt to use your dishwasher when the E14 error appears. This error prevents the machine from operating properly because it cannot accurately monitor water flow, which could lead to overfilling, underfilling, or damage to internal components. Address the issue before running another cycle.
How much does it cost to replace a flow meter sensor on a Siemens dishwasher?
A replacement flow meter sensor typically costs between £25 and £60 for the part alone. If you hire a professional appliance repair technician, expect to pay an additional £80 to £150 for labour, bringing the total repair cost to approximately £105 to £210. DIY replacement can save on labour costs if you are comfortable with appliance repairs.
Will low water pressure in my home cause the E14 error?
Yes, insufficient water pressure can trigger the E14 error because the flow meter sensor may not detect adequate water movement. Most Siemens dishwashers require a minimum water pressure of 0.1 MPa (1 bar) to operate correctly. If your home has consistently low water pressure, you may need to address the underlying plumbing issue or install a pressure booster to prevent recurring errors.
