Quick answer
Code 42 on DCS ActiveSmart RS/RF refrigerators is an ice maker fill tube issue, signalled by alarm beeps or flashing LEDs.
Model compatibility: DCS reuses codes across series and model years, so Code 42 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
