Quick answer

Code 23 on DCS ActiveSmart refrigerators: fault with the water tank sensor, signalled by alarm beeps or flashing LEDs. Press the alarm mute button, then arrange service.

Model compatibility: DCS reuses codes across series and model years, so Code 23 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

Code 23 is a fault with the water tank sensor signalled by alarm beeps or a binary pattern of flashing LEDs, not text.

Code 23 on the refrigerator refers to a fault with the water tank sensor. It is reported by alarm beeps that can be counted or by a binary flashing-LED pattern, not by a written message.

It is used by DCS indoor integrated refrigerators with ActiveSmart in the RS/RF series.

What you can do

If the noise is bothering you, the alarm mute button on an ActiveSmart refrigerator stops it. Contact a service technician for the fault.

Neighboring codes

These codes are close to this one and are often mixed up with it: Ice tray sensor alert (listed right next to this code); Defrost signal (also signalled without any text); the ice maker solenoid entry (compare if the flashes seem different).
