How to Fix 4C Error in Samsung Washing Machine

What the Heck is the 4C Error Anyway?

Let’s start by cracking the code: when your Samsung washing machine flashes the dreaded 4C error, it’s basically waving a red flag that says, “Hey, I’m not getting enough water!” This error is not some mystical riddle—it’s a water supply issue that stops your machine from filling properly. You could be dealing with a kinked hose, clogged inlet filter, or a mischievous water inlet valve.
So before you go planning a dishwasher date with your repair guy, try this DIY fix-it guide that will have your washer humming smoothly again.

Step 1: Inspect the Water Supply Hoses — Don’t Let Them Cramp Your Style

First things first: move your washing machine forward (yes, it’s workout time) to get to the hoses lurking behind. Check that the water supply hoses aren’t kinked, twisted, or pinched. Even a slight bend can choke off the water flow.
Pro tip: Fully open the water tap and make sure hose connections on both ends — washing machine and supply tap — are snug and leak-free.

Step 2: Clean the Inlet Filters — Because Even Tiny Screens Need TLC

Here’s a little-known fact: your washing machine’s inlet hoses have tiny mesh screens that act like gatekeepers keeping dirt out. When these get clogged, water flow slows to a crawl.
Here’s how to clean them out:

  • Turn off the main water supply.
  • Disconnect the water inlet hoses from both the machine and the water source.
  • Use a small brush or your finger to gently scrub the mesh filters inside the hose connectors.
  • Rinse under running water to flush out the gunk.
  • Pop them back in and reconnect everything.

Cleaning these filters often fixes the 4C error in a jiffy — check out these detailed steps from Samsung Support.

Step 3: Check Your Water Pressure — Not Too Low, Not Too High

Now, the water pressure at your tap could be throwing off your machine’s performance. Samsung washing machines generally like a water pressure between 0.5 and 8 bar. If it’s too low, the machine won’t fill properly, triggering that stubborn 4C error.
Try these:

  • Ensure your faucet is fully turned on — it’s surprisingly common to only have it slightly open.
  • Ask your water company or check your pressure meter if you suspect low pressure issues.

If pressure is the culprit, your options range from boosting your home’s overall water pressure to installing a dedicated pressure booster for your laundry setup.

Step 4: Inspect and Possibly Replace the Water Inlet Valve — The Invisible Gatekeeper

The water inlet valve controls flow from your home’s water supply into the washing machine. Over time, sediment can clog it, or it might just wear out.
If the hose check and filter clean didn’t clear up the 4C error, removing and inspecting this valve is your next move.
Heads up: This step is a bit more technical. If you’re comfortable with appliances, here’s the gist:

  • Unplug your washer (safety first).
  • Remove the water inlet valve assembly.
  • Check for obvious blockages or damage.
  • If clogged, clean carefully. If faulty, consider replacing.

If you need to replace the valve, find a suitable part by searching for your washer’s exact model. Or you can check out reliable options through these Amazon links: India and Global/USA.

Step 5: Don’t Forget the Detergent Drawer

Sounds unlikely, right? But a blocked detergent drawer can cause water to back up and sometimes triggers the 4C error. Remove the drawer and clean out any soap residue or blockages. Your machine might thank you for the extra attention.

Step 6: Reset Your Washing Machine — The Classic Power Move

After all those tweaks, give your washer a fresh start:

  • Unplug it from the power source.
  • Wait about 5 minutes to let the internal computer reset.
  • Plug it back in and test a spin cycle.

This often clears error codes that linger even after solving the root problem.

When to Throw in the Towel and Call a Pro

If you’ve checked every hose, rinsed every filter, tested water pressure, and inspected the inlet valve—only for the 4C error to stubbornly stay—you’re probably looking at an internal hardware issue or an electronic glitch beyond a quick fix. Time to ring in Samsung’s official repair techs or an experienced appliance technician.
Remember, messing with internal electronics without the right know-how can lead to more headaches (and wallet aches).
