How to Fix 4C Error in Samsung Washing Machine

Understanding the Dreaded 4C Error Code

So, your Samsung washing machine is flashing the ominous 4C error code. What does it mean? Well, it’s basically your washer’s way of throwing a tiny tantrum because it isn’t getting the water supply it needs. This error often signals a problem like low water pressure, clogged inlet filters, kinked hoses, or even a stuck valve. Simply put, your washer wants water, and it isn’t getting enough.

But hey, don’t reach for your phone just yet to call the repairman. Often, this is a fix-it-yourself situation—and you’ll save some cash while feeling like a home appliance wizard. Let’s dive into how to tackle that 4C error without breaking a sweat.

Step 1: Double Check Your Water Supply Valves

First things first, are the water valves behind your washing machine wide open? Sometimes these valves get nudged closed or partially closed during cleaning or moving your washer. If they’re not fully open, the water flow will be starved.

Go behind your machine and twist those valves counterclockwise until they stop. You want full-on water pressure flowing into the washer’s hungry throat.

Forgot where your valves are? They look like small taps attached to hoses leading into your wall. Don’t worry, they’re not hiding, just sometimes shy.

Step 2: Inspect and Straighten Your Water Hoses

Kinks and twists in your inlet hoses are like kinked straws—they stop proper flow cold. Pull your machine gently away from the wall (don’t pull the hoses too hard!) and check the hoses running from the wall valves to the washer.

Trust me, a smooth hose means a happy water flow.

Step 3: Clean Those Tiny Water Inlet Filters

This is the classic culprit behind the 4C error. Right where the water hose screws into your washer, Samsung hides tiny mesh screens designed to keep gunk out. Over time, minerals and debris can clog these babies, choking off water flow.

Here’s your game plan:

  1. Turn off the water valves.
  2. Unscrew the inlet hoses from both the wall and the washer.
  3. Look inside the washer’s water inlet ports for small round filters (these may be a mesh screen or a plastic cylinder).
  4. Remove the filters carefully with pliers or a small tool.
  5. Rinse them thoroughly under running water to clear debris and mineral scale.
  6. Reinstall them snugly and reconnect your hoses.

After this, your washer’s water intake will be almost as good as new. Sometimes cleaning these filters will fix the error on the spot!

Step 4: Check the Dispenser Drawer for Blockades

Believe it or not, blockages in the detergent dispenser drawer can trip up water flow sensors and cause the 4C code to pop up. Pull out the drawer and clean out any detergent residue, mold, or crusty buildup.

A clean dispenser means water flows freely and the machine feels loved.

Step 5: Test Your Home’s Water Pressure

If the valves, hoses, and filters are in tip-top shape but your washer still glares 4C at you, it’s time to look upstream—the water pressure from your home’s supply.

Disconnect the hose from the washer, point it into a bucket, and turn the water back on to see the flow rate. A decent pressure is generally between 0.5 and 8 bar (7 to 116 psi). Anything less, and your washing machine is just politely begging for more water.

If the flow looks like a weak trickle, you might want to call your plumber or check your house’s main supply valves.

Step 6: Give Your Washer a Friendly Reset

Sometimes machines just need a quick nap to remember their good behavior. Unplug your Samsung washer for about 5 minutes, then plug it back in. This resets the control board and can clear out stubborn error codes lurking in its digital brain.

After resetting, start a wash cycle and see if the 4C error is gone. Fingers crossed!

When to Call in the Pros

If you’ve turned every valve, straightened every hose, scrubbed every filter, and still see 4C, your water inlet valve might be faulty. This tiny part controls your washer filling water at the right time and rate, but when it goes rogue, professional repair or replacement is the next step.
