Samsung Washer - Oc Error Code

Washer detects water overflow.

Meaning

Washer detects water overflow.

The Oc error indicates that the washer has detected an overflow condition. Samsung specifies that this occurs when the water level rises beyond the safe operating threshold. Overflow may be caused by a stuck inlet valve, incorrect water pressure, or a siphoning drain hose. When the washer senses excessive water, it halts the cycle and may initiate a drain sequence to prevent flooding.
