Samsung Washer 4C Error Code: No Water Supply

Quick Answer

4C fires when the water level sensor sees no rise in pressure after the fill valve opens. The fix is almost always mechanical: a closed valve, blocked screen, or failed solenoid coil.

The 4C error on a Samsung front-load washer means the machine started to fill but detected no water after 60 seconds. The most common causes are clogged inlet valve screens (40%), a partially closed supply valve (30%), a failed inlet valve solenoid (20%), or a kinked fill hose (10%). Check both supply valves first, then inspect the inlet screens before testing the solenoid.

What Does the 4C Code Mean?

4C fires when the water level sensor sees no rise in pressure after the fill valve opens. The fix is almost always mechanical: a closed valve, blocked screen, or failed solenoid coil.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Inlet valve screens clogged with sediment or mineral deposits40%
Hot or cold supply valve not fully open24%
Kinked or pinched fill hoses22%
Inlet valve solenoid failed (open or shorted coil)14%

Symptoms You May Notice

  • Washer fills partially then stops with 4C code
  • Machine starts, drum does not fill at all
  • Cycle begins normally then pauses at fill stage

Can you reset a Samsung washer to clear the 4C code?

After fixing the supply issue, unplug the washer for 60 seconds and plug back in. The 4C code clears automatically once the fill cycle completes successfully.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Confirm both hot and cold supply valves behind the machine are

Confirm both hot and cold supply valves behind the machine are turned fully counterclockwise (open). A valve even slightly closed will reduce flow below the minimum 15 psi.

2

Verify household water pressure is at least 15 psi at the washer

3

Turn off both supply valves

4

With the washer unplugged

5

Replace the inlet valve if solenoid tests bad or screens are

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Can a 4C error code appear even when the water is running normally?
Yes. If a screen is 70% blocked, enough water passes to seem normal at the tap but not enough pressure reaches the sensor threshold. Always inspect the screens even if flow looks adequate.
Is the 4C code different from the 4E code on Samsung washers?
Same root fault, different display. 4C appears on front-load models; 4E appears on top-load models. The diagnosis and parts are nearly identical.
How do I clean the inlet valve screens without removing the valve?
Disconnect the fill hoses at the back of the washer. The screens are pressed into the inlet valve ports and can be pulled out with needle-nose pliers, rinsed, and reinserted without removing the valve body.
