Samsung Washing Machine OC Error - Overflow or Overfilling Warning
Samsung washing machine OC means the washer thinks the water level is too high or the drum is overfilling. Check whether water keeps entering, whether the drum looks too full, and whether the drain hose is positioned correctly; stop if OC or 0C returns.
Quick answer
OC: what does it mean and how to fix
What does it mean?
The washer thinks the drum is overfilling or the water level is rising too high.
How to fix first
Turn the machine off and unplug it from the mains.
Why is this happening?
Inlet valve allowing too much water into the drum
When should I call an engineer?
Call an engineer if OC or 0C returns after safe checks, the washer keeps filling, water appears on the floor, or the drain hose and detergent use look normal.
What does this error code mean?
The Samsung OC error code usually means the machine has detected an overflow or overfilling problem. On some models this may also be shown as 0C. In most cases, the cause is a faulty water-level reading, an inlet valve that is not shutting properly, or a drain setup problem that confuses the water level system.
Check first whether the drum looks unusually full, whether water is still entering when it should not, and whether the drain hose is fitted correctly. If water is collecting underneath the appliance as well, the fault can overlap with Samsung LC or Samsung LC1, while a pure sensing issue can look more like Samsung 1C or Samsung IE.
This code usually points to water level control, including the inlet valve, pressure sensor signal, drain hose installation, detergent foaming, and overflow protection.
Symptoms users may notice
- The drum may look fuller than usual during fill or rinse.
- The machine may drain suddenly after detecting too much water.
- Water may continue entering when the programme should have stopped filling.
- OC may appear with foam, poor drain-hose setup, or later leak-style warnings.
What users often notice
- OC may appear soon after the machine fills, especially if the level rises too far or foam builds up.
- Some users notice water keeps entering, the machine looks overfilled, or a leak-style warning appears immediately afterwards.
Why is this happening?
- Inlet valve allowing too much water into the drum
- Water level sensor or pressure signal reading incorrectly, which can overlap with Samsung 1C, Samsung IE, or Samsung 1E
- Drain hose installed too low or siphoning incorrectly
- Excessive detergent foam affecting the water level reading
What this usually points to
This code usually points to water level control, including the inlet valve, pressure sensor signal, drain hose installation, detergent foaming, and overflow protection.
How to fix this safely
- Turn the machine off and unplug it from the mains.
- Check whether the drum looks overfilled or whether water is still entering when it should not.
- Check the drain hose position and surrounding floor if they are safely accessible; if you also find water under the machine, compare the symptoms with Samsung LC or Samsung LC1.
- Let excessive foam settle if too much detergent may have been used, then run one short drain or rinse test only if the water level has returned to normal; if the level still looks wrong without obvious overfilling, compare it with Samsung IE or Samsung 1C.
Can I fix this myself?
MaybeYou can check for obvious overfilling, a badly positioned drain hose, or oversudsing. Persistent OC faults usually need further diagnosis because the fill valve or sensing system may be failing.
Safety boundary: Stop if the machine keeps filling, water continues entering with the programme stopped, or you notice leaks near electrical parts.
What not to do
- Do not keep starting new fill cycles if the drum already looks too full.
- Do not ignore water entering the appliance when the programme is stopped.
Common misdiagnoses
- OC can be mistaken for a drain issue, but the first concern is usually overfill or abnormal water level detection rather than a simple blockage alone.
Reset steps
- Only restart the machine after the drum level looks normal and there is no visible leak.
- Run a short drain or rinse test only if it is safe to do so.
- Stop using the appliance if OC returns, the machine overfills, or water continues entering unexpectedly.
Intermittent vs persistent faults
A one-off OC after oversudsing may clear with correct detergent use, but repeated OC should be treated as a fill or water level control fault.
When to call an engineer
Call an engineer if OC or 0C returns after safe checks, the washer keeps filling, water appears on the floor, or the drain hose and detergent use look normal.
Safety warning
Disconnect the appliance from the mains and avoid using it if water may be reaching electrical parts.

Frequently asked questions
What does OC mean on a Samsung washing machine?+
Samsung OC usually means the washer thinks the drum is overfilling or the water-level reading is too high. Some models show the related code 0C.
How do I fix Samsung washing machine OC?+
Switch off and unplug the washer, check whether the drum is overfilled, look for water still entering, confirm the drain hose is fitted correctly, and let excess foam settle. Stop if OC returns.
Can I still use a Samsung washing machine with OC?+
No. OC can involve overfilling or uncontrolled water level, so continued use risks leakage and repeat shutdowns.
Is Samsung OC the same as 0C?+
Often yes. Many searches mix the letter O and zero, so compare the displayed symbol with the manual, but treat both as overflow or high-water warnings.
Why does Samsung OC keep coming back?+
A returning OC usually means the inlet valve, water-level sensing, drain setup, or oversudsing cause has not been resolved.
Model variation note
Samsung model wording can vary between 0C, 0E, LC, LE, OC, and OE style water-level warnings, so always check the exact manual for your model and match the code to whether the problem is leak, overflow, or level sensing.
