Samsung Washing Machine Error Code OC: What It Means and How to Fix It

Urgent · Risk of Water Damage Also displayed as: 0C OE 0E 1 OC 1 0C
Quick Answer

The Samsung washing machine error code OC means the washer has detected an overflow, indicating too much water in the drum. OC is the updated display format for what older Samsung models showed as OE or 0E. The most common causes are too much detergent (or non-HE detergent), a water inlet valve stuck open, or a drain hose that is siphoning water back into the tub. Close the water supply valves behind the washer immediately, then follow the steps below.

What Does Samsung Washing Machine Error Code OC Mean?

The Samsung washing machine error code OC is an overflow error that indicates the water level inside the drum has risen above the maximum safe threshold. When the washer's water level pressure sensor detects this, it halts the cycle and initiates an emergency drain to protect the machine and your home from water damage.

Samsung introduced the OC (and 0C) display format on newer washer models. It replaces the older OE and 0E codes but represents the exact same fault. Some models also show 1 OC or 1 0C. If you search for any of these codes, the causes and fixes are identical.

This is an urgent error. An overflow means water has exceeded the normal fill level and could spill from the drum. Even if the washer has started an emergency drain, close the water supply valves behind the machine right away to prevent a stuck inlet valve from adding more water.

Why Samsung Washing Machine Shows Error Code OC

1
Too much detergent or non-HE detergent. Excessive suds expand well above the actual water line. The pressure sensor reads the combined water-and-suds volume as an overflow, even when the true water level is normal. Very common
2
Water inlet valve stuck open. The solenoid valve that lets water into the drum has failed in the open position and will not shut off when the control board tells it to. Water keeps flowing and the drum overfills. Common
3
Drain hose siphoning water back. The drain hose is inserted too deep into the standpipe or positioned too low, creating a siphon effect that pulls drained water back into the drum. Occasional
4
Faulty water level pressure sensor. The sensor that measures water depth in the drum is misreading or has failed, either allowing overfill or falsely reporting one. Occasional
5
Clogged or kinked pressure sensor hose. The thin rubber hose that connects the tub to the pressure sensor is blocked by residue or bent, preventing accurate water level measurement. Occasional
6
Main control board issue. The control board is not sending the signal to close the inlet valve at the correct time. This is the least common cause and is diagnosed only after ruling out everything else. Rare

How to Fix Samsung Washing Machine Error Code OC (Step-by-Step)

Close the water supply valves and unplug the washer

Turn off both the hot and cold water valves on the wall behind the washing machine. Then unplug the washer from the electrical outlet. This stops water from entering and powers down the machine safely.

Important: If water is actively overflowing onto the floor, closing the supply valves is the most important step. Do this before anything else.

Clean up any water on the floor

Use towels or a wet/dry vacuum to remove standing water from around and under the washer. Check behind the machine and along the baseboards. Standing water on hard flooring can become a slip hazard, and water on wood or laminate flooring causes damage quickly.

Check your detergent

Look at what detergent you used for this load. Samsung washers with HE (high-efficiency) drum designs require HE detergent. Regular detergent or too much HE detergent creates suds that trigger the overflow sensor. For the next cycle, use only HE detergent at the amount printed on the label for your load size.

Run a Drain and Spin cycle to empty the drum

Plug the washer back in, but keep the water supply valves closed. Select Drain & Spin or Spin Only to pump the excess water out of the drum. Watch to confirm the water drains fully.

Clean the debris filter

Open the small access panel at the lower front of the washer. Place a towel and shallow pan underneath, unscrew the filter cap, and let trapped water drain. Remove any lint, coins, or debris from the filter and screw the cap back firmly. A clogged filter restricts drainage and can make overflow conditions worse.

Check the drain hose depth and position

Pull the washer out enough to see the drain hose at the back. The end of the hose should sit 6 to 8 inches inside the standpipe. If it is pushed deeper, it can create a siphon that pulls water back into the drum after draining. Reposition the hose to the correct depth and confirm there is an air gap at the top of the standpipe.

Reopen the water supply and run a test wash

Turn the supply valves back on and start a short wash cycle with a small load and the correct amount of HE detergent. Stay nearby and watch the fill stage. The drum should fill to a normal level and stop. If the water keeps rising beyond that point, close the valves immediately and call a technician.

If the code returns after these steps, the issue is internal and needs a technician. A stuck-open water inlet valve, a faulty pressure sensor, or a control board problem are not safe to diagnose or repair at home.

When to Stop and Call a Technician

Overflow errors pose a real risk of water damage. Call a professional Samsung appliance repair technician if:

  • Water keeps filling into the drum after the fill stage should have ended, even with the correct detergent and a clean filter
  • The OC code reappears immediately after a power reset
  • You hear the inlet valve buzzing but water does not stop entering the drum
  • The washer shows multiple error codes at once or the display goes blank
  • Water has overflowed onto the floor and you cannot determine the source

How Promix Repairs Samsung Washing Machine OC Errors

When a Promix Appliance Repair technician arrives for an OC overflow error, the first step is confirming the source. The technician will test the water inlet valve with a multimeter to check whether it closes properly, inspect the water level pressure sensor and its hose, and pull the control board's stored error history to see if the overflow has happened before.

The most common professional fix for the OC code is replacing a stuck-open water inlet valve. If the pressure sensor or its hose is the cause, the technician will test and replace the sensor or clear the blockage. Promix technicians carry common Samsung washer and dryer repair parts on every service call, so most OC repairs are completed the same day. Every repair includes a warranty on parts and labor, backed by 10+ years of experience.

How to Prevent Samsung Error Code OC From Coming Back

Always use HE detergent and measure it. Suds overflow from too much or wrong-type detergent is the number one trigger for OC errors on Samsung washers.
Close the water supply valves when the washer is not in use. If the inlet valve ever fails open, closed supply valves prevent an unattended flood.
Clean the debris filter every month. A clear filter keeps drainage flowing smoothly and reduces back-pressure that can contribute to overflow conditions.
Verify the drain hose position after any move. The hose should sit 6 to 8 inches into the standpipe with an air gap. Deeper insertion causes siphoning.
Run a drum-clean cycle every 4 to 6 weeks. The built-in Self Clean or Drum Clean cycle flushes detergent residue from internal components and the pressure hose.

Frequently Asked Questions

Can I keep using my Samsung washing machine with error code OC?

No. The OC code means the washer detected too much water in the drum and stopped the cycle to prevent an overflow. Running another load without resolving the cause risks flooding your laundry area. Close the water supply valves and work through the troubleshooting steps before using the washer again.

Will resetting my Samsung washing machine clear error code OC?

Unplugging the washer for 5 to 10 minutes will clear the OC code from the display. If the overflow was caused by a one-time detergent issue, the reset may be all you need. If the cause is a stuck inlet valve or faulty pressure sensor, the code will return during the next fill cycle.

How long does it take to fix Samsung error code OC?

If the cause is a detergent issue or an improperly positioned drain hose, the fix takes about 15 minutes. If the water inlet valve or pressure sensor needs professional replacement, the repair typically takes 30 to 60 minutes. Promix Appliance Repair stocks common Samsung parts for same-day completion.

Is Samsung error code OC covered under warranty?

A repair for a defective inlet valve or pressure sensor may be covered if your Samsung washer is still within the manufacturer's warranty period (typically one year for parts and labor). Overflow caused by incorrect detergent or improper drain hose installation is considered a usage issue and is generally not covered.

Is Samsung error code OC the same as OE?

Yes. OC (and 0C) is the updated display format that newer Samsung washers use for the same overflow fault that older models displayed as OE (or 0E). The causes, fixes, and repair process are identical. Samsung changed the code label across model generations, but the underlying error is the same.

Should I turn off the water when my Samsung washer shows OC?

Yes, right away. Close both the hot and cold water supply valves behind the washer. If the inlet valve has failed in the open position, water will continue flowing into the drum regardless of whether the washer is powered on or off. Closing the supply valves is the fastest way to stop additional water from entering.
