Troubleshoot error code “4C2” in Samsung washing machine

  • Error: “4C2”
  • Description: Issue with water temperature.
  • Cause: The 4C2 error occurs when the washer detects that the incoming water temperature is hotter than expected for the selected cycle.
  • Solution: Check and correct the connection of water supply hoses, ensure the incoming water temperature is appropriate, and clean hose filters.

If your Samsung washer is displaying the 4C2 error code and you’re unsure what to do, don’t worry! Here at, we’ll guide you step by step to help you resolve this issue and get your washer back to perfect working order.

What Does the 4C2 Error Mean?

The 4C2 error on Samsung washers indicates a problem with the temperature of the incoming water. This can happen if, for example, you’ve just completed a self-cleaning cycle (which uses hot water) and then try to start a cycle with cold water. The washer expects cold water and, upon detecting a higher-than-expected temperature, displays the 4C2 error.

Steps to Resolve the 4C2 Error

1. Check Water Supply Hoses

First, make sure that the hot and cold water hoses are correctly connected to the respective valves. Sometimes, after moving the washer or performing cleaning, hoses can be accidentally swapped.

2. Clean Hose Filters

Over time, hose filters can become clogged with sediment or dirt, affecting the water temperature entering the washer. Here’s how to clean them:

  • Unplug the washer from the power outlet.
  • Close the water supply valves.
  • Disconnect the hoses from the back of the washer.
  • Locate the mesh filters at the water inlet of the washer and carefully remove them.
  • Rinse the filters under running water until completely clean.
  • Reinstall the filters and reconnect the hoses, ensuring there are no leaks.

3. Check Incoming Water Temperature

If the hoses are correctly connected, and the filters are clean, the next step is to check the temperature of the incoming water. If you’ve recently used hot water in the washer, wait a bit for the temperature to stabilize before starting a cycle with cold water.

4. Reset Your Washer

After completing the previous steps, try resetting your washer:

  • Unplug the washer for a few minutes.
  • Plug it back in and turn it on.
  • Select a cycle and see if the 4C2 error has disappeared.

Need Professional Help?

If the 4C2 error persists after following these steps, it may be necessary to contact a specialized technician. Sometimes, the issue can be more complex and related to the temperature sensor or the washer’s electronics.

The 4C2 error can signal an issue with the water temperature in your Samsung washer. By following these steps, you can identify and possibly resolve the problem. Remember to perform regular maintenance on your washer to prevent future errors. If you need additional assistance, don’t hesitate to contact a professional. We hope your washer will be back to normal operation very soon!
