Frigidaire Dishwasher Error Code iC0
Turbidity sensor fault
Common Causes
- 1Optical clarity window filmed over with scale or grease
- 2Corroded pins at the sensor plug
- 3Failed optical emitter or receiver in the sensor
Step-by-Step Troubleshooting
- 1
This is the little optical eye that judges how dirty the wash water is so the machine can size the cycle; when its window fouls, it reads permanent murk and flags itself, so a cleaning is the first move
- 2
Kick off an empty run with a dishwasher descaler to strip the mineral haze off the lens from the water side without any teardown
- 3
If that does not clear it, lift the lower arm and coarse filter, find the sensor down in the sump, and polish its clear window with white vinegar on a soft cloth until it is truly transparent again
- 4
With a spotless lens still faulting, unplug the sensor and inspect its pins for the green corrosion that base-of-tub moisture breeds before you conclude the optics have died
Pro Diagnostic Tip
Because this eye only estimates soil to tune the wash, a fouled lens is nearly always the whole story — descale from the water side first, then hand-polish the window. A genuine electronic failure of the emitter or receiver is rare next to plain hard-water film on the glass.
