Samsung washers 4C2 error

The washer detects extremely hot water at the cold-water inlet.

4C2

What this code can mean

Samsung identifies this as a hot/cold supply error that commonly occurs when the inlet hoses are connected to the wrong washer inlets.

Safe first checks

  1. 1
    Stop the cycle and turn off both water supply valves before handling the hoses.
  2. 2
    Confirm the cold supply reaches the cold inlet and the hot supply reaches the hot inlet.
  3. 3
    Restore the water supply and retry only after the hose connections are secure and dry.

Possible causes

  • The cold-water supply hose is connected to the hot-water inlet.
  • The hot- and cold-water supply hoses are reversed.
Stop conditions
  • Stop and request service if a hose, connector, valve, or washer inlet is damaged or leaking.

Use Samsung support or an authorized servicer if correct hose routing does not clear the code.
