The E17 error on your Siemens Dishwasher means water is flowing into the machine when it shouldn't be, triggering the overflow protection system. This typically indicates a faulty inlet valve or a problem with the water level control.
| Error code | E17 |
|---|---|
| Meaning | Continuous water inflow or overflow protection activated |
| Severity | High — Can cause water damage if not addressed immediately |
| Time to fix | 20–60 minutes |
| Tools needed | Screwdriver, pliers, towels, multimeter (optional) |
What the E17 error means
The E17 error code indicates that your Siemens dishwasher has detected uncontrolled water inflow or that the overflow protection has been triggered. This safety feature activates when the water level sensor detects too much water in the base pan beneath the dishwasher tub. When this happens, the machine immediately stops the wash cycle and drains to prevent flooding your kitchen.
Common causes
- Faulty water inlet valve stuck in the open position allowing continuous water flow
- Blocked or kinked drain hose preventing proper water evacuation
- Defective water level pressure switch giving incorrect readings
- Leak in the dishwasher tub or door seal causing water to collect in the base
- Failed flow meter or aquastop system malfunction
- Clogged filters causing water backup and overflow
How to fix the E17 error
- Turn off the water supply and power: Immediately turn off the water supply valve under your sink and unplug the dishwasher from the mains. This prevents further water inflow and ensures your safety while inspecting the machine.
- Check for visible leaks and water in the base: Remove the lower kickplate panel at the bottom front of the dishwasher. Look for standing water in the base pan. If water is present, soak it up with towels and identify where it came from by inspecting hoses, the door seal, and the tub for cracks or damage.
- Inspect the water inlet valve: Locate the inlet valve where the water supply connects to the dishwasher, usually at the bottom left. Disconnect the water supply line and check if the valve is stuck open or has debris preventing it from closing. If the valve appears faulty or leaks when closed, it needs replacement.
- Examine the drain hose: Check the drain hose for kinks, blockages, or improper installation. The hose should loop up higher than the water level in the dishwasher before connecting to the drain. Clear any blockages and ensure proper positioning.
- Clean the filters and check the sump: Remove the filter assembly from the bottom of the dishwasher tub. Clean thoroughly under running water and check the sump area for debris or foreign objects that could interfere with water level detection or drainage.
- Test and reset: After addressing any issues, reconnect power and water supply. Run a rinse cycle to test if the error has cleared. If E17 persists after these checks, the pressure switch or control board may require professional replacement.
FAQ
Can I continue using my Siemens dishwasher with the E17 error showing?
No, you should not use the dishwasher when E17 appears. This error indicates a serious water control problem that could lead to flooding and water damage to your kitchen floor and cabinets. Address the issue immediately before running another cycle.
How much does it cost to fix the E17 error on a Siemens dishwasher?
If you fix it yourself, a replacement inlet valve costs between £20 and £50, while a new pressure switch costs £15 to £40. Professional repair typically ranges from £80 to £180 including parts and labour. The exact cost depends on which component has failed and your location.
Will resetting my Siemens dishwasher clear the E17 error?
Simply resetting the dishwasher will not permanently fix an E17 error because it indicates an actual fault with water control. While you can try turning off the machine for 10 minutes to reset the electronics, the error will return if the underlying issue with the inlet valve, pressure switch, or leak is not resolved.
