Samsung Washer Error Code 4C (What It Means & How to Fix It)

Is your Samsung washer showing error code 4C on the display? Don’t worry. This is a common issue related to water supply problems, and in many cases, you can fix it yourself.

In this guide, we’ll explain what Samsung washer error code 4C means, what causes it, and how to fix it step by step.

Samsung Washer Error Code 4C

What Does Samsung Washer Error Code 4C Mean?

The 4C error code indicates that your washer is not receiving enough water. This usually happens when there is a problem with the water supply, hoses, or inlet valve.

Some older Samsung models may display this as “4E,” but the meaning is the same.

Common Causes of Error Code 4C

  • Water supply turned off
  • Kinked or bent water hose
  • Clogged inlet hose filter
  • Low water pressure
  • Faulty water inlet valve

Safety First

  1. Turn off the washer.
  2. Unplug it from the power outlet.
  3. Turn off both hot and cold water supply valves.

Step 1: Check the Water Supply

Make sure both hot and cold water valves are fully open.

  1. Locate the valves behind the washer.
  2. Turn them counterclockwise to fully open.
  3. Restart the washer.

If the error disappears, the issue was simply the water supply.

Step 2: Inspect the Water Hoses

Kinked or bent hoses can restrict water flow.

  1. Pull the washer slightly away from the wall.
  2. Inspect both hoses for bends or damage.
  3. Straighten or replace if necessary.

Step 3: Clean the Inlet Hose Filters

Samsung washers have small mesh filters inside the hose connections to prevent debris from entering.

  1. Disconnect the water hoses from the back of the washer.
  2. Locate the small mesh filters inside the inlet ports.
  3. Carefully remove and rinse them under running water.
  4. Reinstall the filters and reconnect the hoses.

Turn the water back on and test the washer.

Step 4: Check Water Pressure

Low household water pressure can trigger the 4C error.

Samsung washers typically require a minimum pressure of 20 PSI. If pressure is too low, consider contacting a plumber.

Step 5: Test the Water Inlet Valve

If all previous steps fail, the water inlet valve may be defective.

  • Use a multimeter to test for continuity.
  • If the valve does not open properly, replace it.

How to Reset Samsung Washer After 4C Error

  1. Unplug the washer for 5 minutes.
  2. Plug it back in.
  3. Run a short test cycle.

When to Call a Technician

Contact a professional if:

  • The inlet valve needs replacement and you are not comfortable repairing it.
  • The control board appears faulty.
  • The error persists after all troubleshooting steps.

Frequently Asked Questions

Is Samsung error code 4C serious?

No. It usually indicates a simple water supply issue.

Can I still use my washer with 4C error?

No. The washer will not start until the water supply issue is resolved.

Why does my Samsung washer show 4C during winter?

Final Thoughts

Samsung washer error code 4C is typically caused by water supply problems such as closed valves, clogged filters, or low pressure. In most cases, cleaning the inlet filters or checking the hoses resolves the issue quickly.

If the problem continues, consult a certified appliance repair technician for further diagnosis.
