Error code23
ApplianceRefrigerator
Code 23 means there is a water tank sensor issue. The refrigerator shows it as beeps from the alarm, counted, or as LEDs flashing in binary; the display carries no words for it.
If you hear the alarm and the count matches 23, or the LED pattern matches, the water tank sensor is the part reporting trouble.
Within San Francisco and the greater Bay Area, DCS refrigerator repair is the reference page and (415) 969-2271 the number to use. State code 23 and your model number, and add what you did before calling.
Model compatibility: DCS reuses codes across series and model years, so 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.
