Samsung Washer OC Error Code

Overflow error

Applies to: All digital display models. May also appear as 0C, OE, 0E, 1 OC, 1 0C.

What's going on

The OC code on a Samsung washer means the washer thinks there is too much water in the tub. This is an overflow warning, so the washer stops filling to help prevent a leak. Turn off the water supply to the washer, protect the floor, and then do a few simple checks before calling for help.

Your washer uses a water level pressure sensor to measure how much water is in the tub. As water fills, air pressure in a small tube rises, and the sensor reads that pressure. When the reading goes past the safe limit, the control board shows OC and tries to stop the fill.

This matters because an overfilled washer can spill water onto your floor. If the water inlet valve is stuck open, water may keep flowing even after the washer is turned off. That can cause water damage quickly.

This code applies to Samsung washers with a digital display. Error codes can differ between model generations, so confirm the meaning with your model number. It is usually printed on a label inside the door or on the back of the washer.

Likely causes

water inlet valve — The water inlet valve opens and closes to let water into the washer. If it sticks open or leaks through, water keeps flowing and overfills the tub.
water level pressure sensor — If the sensor is faulty, it may report a high water level that isn't really there. A clogged or kinked sensor tube can also cause a false reading.

The same code can mean different things on different model generations. Check the model number on your washer's rating plate before ordering parts.

Can you fix it yourself?

Doable for an experienced DIYer with the right part, but many people still call a technician.

Safe things to check first

Turn off both water supply valves behind the washer right away, and place towels or a pan on the floor to catch any water. Then unplug the washer or switch off its breaker.
Look inside the tub. If it is full of water even with the power off, the water inlet valve is likely stuck open. Keep the water supply shut off until it is repaired.
Check the detergent and softener dispensers for heavy suds or buildup. Too much detergent or non-HE detergent can create extra suds that confuse the level reading. Use only HE detergent in the right amount.
After the tub has drained and the floor is dry, plug the washer back in, turn the water back on, and run a short rinse cycle while watching closely. If OC returns or water keeps rising, turn the water off again and stop.

When to call a technician

Call a qualified appliance technician if water keeps filling with the power off, or if OC returns after your checks. A handy owner can often replace the water inlet valve with the correct part for their model. Always unplug the washer and shut off the water before touching anything inside it.
