The E16 error on your Siemens Dishwasher means the water inlet valve is continuously filling the dishwasher, triggering the anti-flood protection system. This error typically requires immediate attention to prevent water damage.
| Error code | E16 |
|---|---|
| Meaning | Continuous water filling detected - anti-flood system activated |
| Severity | High — can cause water damage if not addressed promptly |
| Time to fix | 20–60 minutes |
| Tools needed | Towels, screwdriver, pliers, multimeter (optional) |
What the E16 error means
The E16 error code indicates that your Siemens dishwasher has detected continuous or excessive water filling. The dishwasher's anti-flood protection system has been triggered, either by water in the base pan or by a malfunctioning inlet valve that won't stop filling. This safety feature prevents flooding and water damage to your home.
When this error appears, the dishwasher will typically drain any water and refuse to operate until the issue is resolved. The error protects your appliance and home from potential water damage caused by uncontrolled water flow.
Common causes
- Faulty water inlet valve stuck in the open position allowing continuous water flow
- Water in the base pan triggering the anti-flood float switch due to a leak
- Blocked or kinked drain hose preventing proper water drainage
- Defective pressure switch sending incorrect signals about water levels
- Damaged door seal or hose connections causing internal leaks
- Faulty electronic control board incorrectly managing the water inlet valve
How to fix the E16 error
- Disconnect power and water supply: Turn off the dishwasher at the mains and shut off the water supply valve. This is essential for safety before any inspection or repair work. Wait a few minutes to allow the appliance to reset.
- Check for water in the base pan: Carefully pull the dishwasher forward and tilt it slightly backwards to check the base pan underneath. If water is present, use towels to soak it up completely. This water may have triggered the anti-flood switch. Look for signs of leaks from hoses, seals, or the pump.
- Inspect the water inlet valve: Locate the water inlet valve where the supply hose connects to the dishwasher. Check for debris or scale buildup that might prevent it from closing properly. Test the valve with a multimeter for continuity when it should be closed. If faulty, the inlet valve will need replacement.
- Examine all hoses and connections: Check the inlet hose, drain hose, and internal hoses for kinks, blockages, or damage. Ensure all connections are tight and secure. Look for any cracks or splits that could cause leaks. Replace any damaged hoses.
- Test the pressure switch: The pressure switch controls water levels by detecting air pressure changes. Locate it near the base of the tub and check its hose connection for blockages or damage. If the switch is faulty, it may continuously signal for more water. Test with a multimeter or replace if suspect.
- Reset and test the dishwasher: Once repairs are complete, ensure the base pan is completely dry. Reconnect the water supply and power. Run a short cycle to verify the error is cleared and the dishwasher fills and drains correctly without triggering the E16 error again.
FAQ
Can I reset the E16 error without fixing the problem?
While you can temporarily reset the error by disconnecting power for several minutes and ensuring the base pan is dry, this won't solve the underlying issue. The E16 error will return if the root cause isn't addressed. The anti-flood system is a critical safety feature that should not be bypassed.
How much does it cost to fix an E16 error on a Siemens dishwasher?
If you can fix it yourself by cleaning the base pan or replacing a faulty inlet valve, costs range from £30 to £80 for parts. Professional repair typically costs between £120 and £250 including labour and parts. The water inlet valve is the most common replacement part for this error.
Is it safe to use my Siemens dishwasher with an E16 error?
No, you should not use the dishwasher when the E16 error is displayed. This error indicates a potential flooding risk, and the appliance's safety system has intentionally disabled operation. Using the dishwasher could cause water damage to your home and potentially damage the appliance further.
