Electrolux Dishwasher Error Code i0 (11 blinks)

The i0 code, displayed as 11 blinks, indicates a turbidity sensor fault. The control board expects the turbidity sensor to reach a calibration signal threshold within 15 seconds, and this threshold was not met. The dishwasher will continue to run but defaults to assuming maximum soil load, which can lead to longer and less efficient cycles.

A reset may temporarily clear the code from the display, but if the underlying sensor or wiring issue has not been corrected, the fault will return once the dishwasher runs through its calibration check again. A reset is useful for confirming whether the error is intermittent, but it is not a lasting fix for a failed or fouled turbidity sensor.

If the issue is simply a dirty sensor, the repair costs nothing beyond your time. If the turbidity sensor needs replacement, parts typically range from $20 to $60 depending on the model, plus labor if you hire a technician. A professional diagnosis and repair visit can range from $100 to $250 in total, depending on your location and whether any additional components such as the wiring harness or control board are involved.

In many cases, yes. Start by inspecting the turbidity sensor for any visible contamination such as grease, food debris, or mineral scale, and clean the sensor surface if buildup is present. Also check that the wiring harness connected to the sensor is fully seated and free of damage. If cleaning and reconnecting the wiring do not clear the fault, the sensor likely needs to be replaced, which is a straightforward part swap for someone comfortable with basic appliance repair.

Yes, the dishwasher is generally safe to operate with this fault active. The control system enters a fallback mode that assumes dirty water at all times, so dishes will still be washed. However, cycles may be longer and water usage higher than normal, and washing performance may be inconsistent since the machine cannot optimize based on actual water clarity.
