Direct answer
What 4C means
Samsung washer code 4C indicates that water is not being supplied correctly. Manufacturer guidance directs users to check the faucets, hot and cold hose connections, inlet hoses, inlet filters, and drain-hose placement before requesting service.
Also shown as: 4E
Before you begin
Safety first
Close the water faucets and disconnect electrical power before loosening any inlet hose. Water under pressure can spill near electrical connections.
- Turn off both hot and cold supply faucets before touching hose connections.
- Unplug the washer before removing an inlet hose or cleaning a mesh filter.
- Keep the electrical outlet and power cord dry.

- Some Samsung regions and older controls may display 4E for a related water-supply condition. Confirm the code and hose requirements in the exact model manual.
Common paths to check
These are source-backed possibilities, not probability estimates for your specific unit.
- 01 One or both water faucets are closed or the home supply is interrupted.
- 02 An inlet hose is kinked, reversed, or connected incorrectly.
- 03 A user-serviceable inlet mesh filter is obstructed.
- 04 The drain hose is positioned so that water siphons out during filling.
Decision path
Safe checks, in order
- 1
Verify water supply
Confirm that both supply faucets are fully open and that other fixtures have normal water flow. Inspect the visible inlet hoses for kinks or crushing.
Expected: Hot and cold water are available and both hoses have a clear path.
If not resolved: Confirm that hot and cold hoses are connected to their matching inlets.

Check hose connections and filters
Close both faucets and unplug the washer. Following the model manual, verify the hose connections and inspect only the removable inlet mesh filters identified for user cleaning.
Expected: Connections match the marked inlets and the mesh screens are clear and undamaged.
If not resolved: Inspect the model-specific drain-hose height and insertion depth.

Check drain-hose position
Compare the drain hose position with Samsung's installation drawing, making sure it is not kinked, airtight in the standpipe, or inserted farther than specified.
Expected: The hose is secured at the correct height with an air gap at the standpipe.
If not resolved: Request service rather than opening the inlet valve or control cabinet.
Reset and test
- Open the water faucets after all hose connections are secure.
- Restore power after the work area is dry.
- Run the model's test or rinse cycle and watch the fill process for leaks.
Important: Turning power off and on may clear the message, but 4C will return if the water-supply condition remains.
Escalation point
Stop and arrange service when
- A hose, valve connection, or washer cabinet leaks.
- The home's water supply is normal but the washer does not admit water.
- 4C returns after installation and accessible filter checks.
