What Does Error dF Mean?
The dF error code on your Ariston refrigerator indicates an active defrost cycle, which may momentarily pause cooling. Look for signs like frost buildup or unusual sounds from the evaporator fan during this time. Typically, the display will clear itself within 30 to 60 minutes if the defrost cycle operates normally. Keep the refrigerator door closed to help the defrost process complete efficiently.
Common Symptoms:
- Display shows "dF"
- Cooling may appear reduced or paused when code shown
- Code typically clears on its own
Possible Causes
- Automatic defrost cycle active (low)
