4C on a Samsung washer
What does 4C mean?
Water-supply error — the washer expected water to enter the tub at a certain rate and did not detect it.
The Samsung 4C code is the single most common Samsung washer code we see in the GTA. The cause is almost always upstream of the washer itself — a kinked hose or clogged filter — and a homeowner with five minutes can often resolve it without a service call.
Common causes
- Inlet hose kinked or clamped behind the washer
- Inlet hose mesh filter clogged with sediment
- Water shut-off valve at the wall partially closed
- Faulty water inlet valve solenoid
- Pressure sensor or hose disconnected
Checks you can safely try first
- 1 Check that both hot and cold supply valves at the wall are fully open
- 2 Pull the washer out and look for kinks in the inlet hoses
- 3 Unscrew the hoses at the washer end and clean the mesh filters
- 4 Confirm the house has water pressure at other fixtures
When to call a technician
If the supply hoses are clear, the valves are open, and the code still appears within the first 60 seconds of a cycle, the water inlet valve assembly likely needs replacement. We carry the part for most Samsung top- and front-loaders.
