DIAGNOSIS: The clean indicator is on a timer, not a sensor. It turns on after 30 days of use as a reminder, and you have to manually reset it after cleaning.
FIX: With the machine plugged in and in standby mode (not actively making ice), press and hold the "Clean" button for 3-5 seconds. You'll see the clean light flash and then turn off. That's it. The timer is now reset for another 30 days.
IF THAT DIDN'T WORK: If holding the button does nothing, the unit might be in a different mode. Make sure there's no active error code (like a blinking blue light) first. Clear any error by checking water supply, then try the reset again.
HEADS UP: Yeah, this one's common. doesn't make the "hold to reset" part super clear. Just pressing the button starts the clean cycle, but holding it is the separate reset function for the light.
