Quick answer
Code 6 on a DCS ActiveSmart refrigerator is a freezer compartment sensor issue, signalled by alarm beeps or flashing LEDs.
Model compatibility: DCS reuses codes across series and model years, so 6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A freezer compartment sensor issue, signalled by beeps or LEDs rather than text.
A freezer compartment sensor issue is what code 6 stands for on a DCS ActiveSmart indoor integrated fridge in the RS/RF series. Nothing appears on a display. The code is sounded out in alarm beeps or flashed by LEDs in a binary sequence.
Handling the alarm
Use the alarm mute button to stop the noise. Fixing the sensor problem itself takes a service technician.
