Samsung Washing Machine Error Code 0C

The washer thinks the water level has risen too high or the drum is overfilling. The most likely cause is inlet valve allowing too much water into the drum. Check first: check whether the drum looks overfilled or whether water is still entering when it should not.

Quick decision

0C

high severity

What it usually means

The washer thinks the water level has risen too high or the drum is overfilling.

First safe action

Turn the machine off and unplug it from the mains.

Stop and call an engineer when

Call an engineer if 0C returns after safe checks, the washer keeps filling, water appears on the floor, or the drain hose and detergent use look normal.

Meaning

The Samsung 0C error code usually means the machine has detected too much water in the drum. On many models it is the same kind of warning family as Samsung OC, and it often points to an inlet valve not shutting, a faulty level reading, or a drain setup problem that confuses the pressure system.

Check first whether the drum looks unusually full, whether water is still entering when the programme should have stopped filling, and whether the drain hose has been fitted too low. If water is also collecting underneath the appliance, compare the symptoms with Samsung LC or Samsung LC1, while a pure sensing problem can look closer to Samsung 1C.

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

  1. The drum may look overfilled or fuller than usual.
  2. The code may appear during filling or rinsing.
  3. The washer may drain unexpectedly after deciding too much water is inside.

What users often notice

  1. Users often describe this as the machine filling too high, not stopping the water, or suddenly trying to protect itself mid-cycle.
  2. Some machines show 0C where other Samsung models show OC for the same kind of overfill warning.

Likely causes

  1. Inlet valve allowing too much water into the drum
  2. Pressure sensor or level-reading fault, similar to Samsung 1C or Samsung 1E
  3. Drain hose installed too low and siphoning incorrectly
  4. Foam or residue 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 it safely

  1. Turn the machine off and unplug it from the mains.
  2. Check whether the drum looks overfilled or whether water is still entering when it should not.
  3. Inspect the drain hose position if it is safely accessible; if water is appearing underneath the appliance as well, compare the fault with Samsung LC or Samsung LC1.
  4. 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 and the behaviour no longer matches Samsung OC.

Can I fix this myself?

Maybe

You can safely check for obvious overfilling, a badly positioned drain hose, or oversudsing. Persistent 0C faults usually need diagnosis because the inlet valve or level-sensing system may be failing.

Safety boundary: Stop if the machine keeps filling, water continues entering with the programme stopped, or you notice water leaking near electrical parts.

What not to do

  1. Do not keep starting new fill cycles if the drum already looks too full.
  2. Do not ignore water entering the appliance when the programme has been stopped.

Common misdiagnoses

  1. 0C can be mistaken for a simple drain issue, but the first concern is usually overfill or abnormal water-level detection.

Reset steps

  1. Only restart the machine after the drum level looks normal and there is no visible leak.
  2. Run a short drain or rinse test once only.
  3. Stop using the appliance if 0C returns, the machine overfills again, or water keeps entering unexpectedly.

Intermittent vs persistent faults

A one-off 0C after oversudsing may clear with correct detergent use, but repeated 0C warnings should be treated as a fill or water-level control fault.

When to call an engineer

Call an engineer if 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

Can I still use the appliance with Samsung 0C showing?+

No. 0C is an overfill-style warning, so continued use can lead to leaks, repeat shutdowns, and water damage.

Is Samsung 0C the same as OC?+

On many Samsung models, 0C and OC point to the same overfill or abnormal water-level family. Always check the exact manual for your display style.

Will resetting fix Samsung 0C permanently?+

Only if the cause was temporary, such as oversudsing. If the code returns after one safe test, the fill or sensing problem is still present.

What happens if I ignore Samsung 0C?+

You risk overflow, leaks, repeated cycle failures, and extra stress on the valve, pump, and water-level system.

Model variation note

Samsung display wording can vary between 0C, OC, LC, and OE style water-level warnings, so always check the exact manual for your model.
