Samsung 4C: Washer not receiving adequate water supply

The washer expected water to enter within a set time but detected too little or none, so it stops filling. The cause is usually a closed tap or a restricted supply hose rather than a machine fault.

Schematic illustration of a typical washing machine — not your exact model.

Before you start — unplug the appliance and turn off the water supply. You'll be working near water and electrical parts, and drained water can be hot. If a step involves the pump, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Open the taps fullyConfirm both hot and cold supply valves feeding the washer are turned on all the way.
2Straighten the fill hosesCheck the inlet hoses for kinks, sharp bends, or crushing behind the machine, and confirm they are not damaged.
3Clean the inlet mesh filtersTurn off the taps, unscrew the hoses from the back of the washer, gently pull out the small mesh filter screens, rinse them under running water, and reinsert them.
4Verify water pressureEnsure supply pressure is within the required range; very low pressure or flow can trigger the code.
5Restart the cycleReconnect hoses, turn on the taps, and run a cycle. If 4C persists with open taps and clean filters, the inlet valve may need replacement.

Still showing 4C?

If you’ve worked through every step and 4C keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.

Which models this applies to
