Quick answer

4C

medium severity

Water is not entering the machine properly

First safe action

Turn the washing machine off and unplug it from the mains.

Meaning

Samsung washing machine error code 4C usually appears when the appliance is not filling with water as expected. A supply issue, an inlet hose restriction, or an inlet valve fault are common starting points.

Likely causes

  • Water tap closed or only partly open
  • Inlet hose kinked or restricted
  • Blocked inlet filter or inlet valve problem

Safe first checks

  • Turn the washing machine off and unplug it from the mains.
  • Check that the water supply tap is fully open and the inlet hose is not kinked.
  • If it is safe and accessible, inspect the inlet filter for debris before testing again.

How to reset

  • Restore power once the water supply checks are complete.
  • Run a short programme to see whether the code clears.

When to call an engineer

If the code returns with a normal water supply, the inlet valve, wiring, or control system may need professional attention.

Safety warning

Disconnect the washing machine from the mains before checking any accessible hose, filter, or connection.

Frequently asked questions

Can I keep using a Samsung washing machine with 4C showing?+

It is usually better to pause use until you have completed the safe first checks for 4C, then test the machine with a short programme.

Will resetting clear 4C for good?+

A reset may clear a temporary interruption, but if 4C comes back after the first safe checks, the underlying fault still needs attention.
