Samsung Washing Machine Error Code OC

DIY checks first

What this code means

OC: Water has overflowed

The tub has filled beyond the safe level. The machine stops to prevent flooding. A one-off can be a glitch; a repeating overflow points at the inlet valve or the water level sensor.

Also shown as: OE, OF, E3

Common causes

Water inlet valve stuck open
Water level (pressure) sensor fault
Drain hose fitted so low that water siphons out and the machine keeps refilling
Too much foam confusing the level sensing

What to check, in order

Turn the water taps off if the machine is still filling.
Restart the machine and run a spin cycle to empty the tub.
Check the drain hose is not pushed far down a floor drain, which can cause siphoning.
If it overfills again on the next cycle, book a repair: the valve or sensor needs testing.

Safety first. Switch the machine off and unplug it before cleaning filters or moving hoses. Expect water to come out when you open a pump filter; keep a tray and towel ready. If you are not comfortable with any step, stop and call a technician.

Parts that may be involved
