Fill tube issue, code 43
Seeing 43 means the ice maker fill tube has an issue on an ActiveSmart indoor integrated DCS refrigerator (RS/RF). The fridge relays this by beeping a counted number of times or by flashing LEDs in binary, since it shows no text.
Words are never printed for 43. Jot down the beep count or the LED sequence, mute the alarm if needed, and keep in mind that silence does not mean the fill tube issue has gone away.

Bay Area owners should call (415) 969-2271 and mention code 43; the overview at DCS refrigerator repair is also worth a look. Gather the model number first.
Model compatibility: DCS reuses codes across series and model years, so 43 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
