How to Fix 4C Error in Samsung Washing Machine

What on Earth is the 4C Error Anyway?

Picture this: you launch your beloved Samsung washing machine for a spin, only to be greeted by a flashing “4C” error code on the display. Cue dramatic pause. The 4C error typically signals a water supply problem. That’s right, your machine is basically waving a red flag to say, “I can’t get enough water in here!”

Multiple culprits can cause this code, including kinked or blocked hoses, clogged inlet filters, or a malfunctioning water inlet valve. But fear not — your in-house washing machine whisperer (that’s you now) is here to decode and conquer the problem.

Step 1: Channel Your Inner Inspector—Check Those Hoses

First thing’s first, go all Sherlock Holmes on your water supply hoses. A kinked or twisted hose will choke the water flow faster than you can say “laundry day disaster.” According to experts on the iFixit forum, the 4C code often pops up because the hose is blocked or bent.

  • Gently straighten any twists or kinks.
  • Check the connections at both ends—washer and water supply tap—to ensure they’re snug, not loose.
  • If you spot any damage like cracks or leaks, swap out the hose (affiliate links below will make it painless).

Pro tip: A strangled hose = a grumpy washing machine. This simple check knocks out a big chunk of 4C error cases.

Step 2: Filter Your Way to Freedom—Clean That Mesh Screen

Next up: channel your inner surgeon and get those inlet filters squeaky clean. There are tiny mesh screens where the water hose connects to your washer. Over time, these can clog with mineral deposits, lint, or mysterious bathroom debris.

  1. Turn off the water supply tap.
  2. Disconnect the hose carefully from the washing machine.
  3. Look inside the hose connector and washer inlet for the mesh filter. This little guy is usually a fine metal or plastic screen.
  4. Rinse the filter under running water to clear any grit or buildup. Use a soft brush if necessary.
  5. Reattach the hose securely.

Voila! You just gave your washing machine a breather and a better water flow. Don’t just take my word for it—watch how this step solves the issue in this helpful YouTube video.

Step 3: Open the Floodgates—Check Your Water Supply

It might seem obvious, but make sure your water tap is actually open all the way. Since the 4C error is about water not filling properly, this is the first step to rule out simple human error.

Also, consider your water pressure. Samsung recommends water pressure between 0.5 bar and 8 bar. Lower pressures might struggle to get enough water into your machine fast enough, leading to this error.1

Step 4: Let’s Not Forget the Detergent Drawer

Sometimes the problem isn’t the water itself but where it’s trying to go. A clogged detergent drawer can hinder water flow and confuse your washer’s sensors. Give the detergent drawer a good clean and rinse to prevent potential blockages affecting water supply detection (source).

Step 5: The Inlet Valve—Your Last Line of Defense

If your hoses and filters are cleared, taps are open, detergent drawer is sparkly, and the dreaded 4C error still mocks you, it’s time to investigate the water inlet valve itself.

The valve controls water flow into your machine and can fail mechanically or electrically. A faulty valve won’t open to let water in, triggering that pesky 4C error. Replacing it is a bit more advanced but often necessary when all else fails.

For guided repairs, see detailed video tutorials like this one and consider ordering a replacement valve from trusted sources.

Step 6: Quick Reset—Unplug and Breathe

Here’s a neat tech trick for you: unplug your washing machine from power for about 5 minutes. This resets the control board and can sometimes clear stubborn error codes.

Once powered back on, see if the 4C error is gone and your washer behaves like the hardworking champ it was born to be.

When to Call in the Pros (But Only If You Must)

If after all these efforts your Samsung machine still throws a 4C tantrum, this might be a sign of an internal malfunction beyond simple fixes. At this stage, a qualified repair technician can diagnose electrical or mechanical faults inside the washer safely.

Remember, poking around inside your washing machine’s electronics without experience is a one-way ticket to stress town and possibly voided warranty.
