If your Samsung washer suddenly flashes a 4C or 4E error code, and your laundry cycle comes to an abrupt stop, don’t panic. This one’s more common than you think, and in many cases, you can fix it yourself without calling for service.
In plain terms, this code means your washer isn’t filling with water properly. But the reasons behind that can range from something simple, like a kinked hose, to a more complex internal issue.
Let’s go through everything you need to know: what this code means, what causes it, and what you can do before calling a pro.
What Does the Samsung Washer Error Code 4C Mean?
On most Samsung washing machines, 4C (or 4E on older models) signals a water supply problem.
The washer’s sensors detect that water isn’t entering the drum fast enough or at all during the filling stage.
When this happens, your washer stops the cycle to prevent damage.
Translation: your washer’s thirsty, but nothing’s coming out of the tap.
Why You’re Seeing the 4C/4E Error Code
Here are the most common reasons this happens, based on years of hands-on experience from our technicians across Barrie:
1. Water Taps Are Closed or Partially On
It happens more often than you’d think. The hot or cold water valve isn’t fully open.
Quick fix:
Check behind the washer to make sure both water supply valves are fully turned on. Samsung washers need both hot and cold water flow to function properly, even if you selected a cold wash.
2. Kinked or Blocked Water Hoses
If one of the hoses feeding your washer is bent, pinched, or clogged with debris, the water flow slows down and triggers the error code.
What to do:
-
Turn off the water supply.
-
Detach the hoses from the back of the washer.
-
Run water through each hose into a bucket. It should flow freely.
-
If the stream is weak, rinse or replace the hose.
Pro Tip: Use stainless steel braided hoses instead of rubber ones. They’re more durable and less likely to kink.
3. Dirty or Clogged Inlet Filters
Each water hose connects to a small mesh filter inside the washer’s water inlet valves. Over time, minerals and debris from your water supply can clog them.
Fix:
-
Gently pull out the filters using needle-nose pliers.
-
Rinse them under warm running water to remove buildup.
-
Never use sharp tools to poke them. They can easily tear.
-
Reinsert them snugly and reconnect the hoses.
4. Low Water Pressure
Samsung washers are sensitive to water pressure. If your home’s water flow is too weak, the washer may misread it as a supply issue.
Check:
-
Make sure the household water pressure is at least 20 psi (138 kPa).
-
Try running another faucet in the house. If it’s weak too, it’s a plumbing issue, not your washer.
In Barrie, fluctuating municipal water pressure is fairly common, especially in older neighborhoods.
5. Incorrect Hose Installation
When setting up a washer, it’s easy to accidentally cross the hot and cold hoses or forget to secure them fully.
That mix-up can confuse the washer’s sensors and trigger a 4C code.
Solution:
Double-check hose placement and make sure they’re screwed on tightly.
6. Faulty Water Inlet Valve
If you’ve checked everything above and the washer still won’t fill, the inlet valve (the component that opens to let water in) may have failed.
You’ll need to test it for continuity with a multimeter or have a technician replace it.
7. Control Board or Sensor Issue
Less common, but possible. The control board may be sending or reading the wrong signal.
If you’ve ruled out water flow problems, this may be the culprit.
How to Fix the Samsung Washer 4C Error – Step-by-Step
Before calling in reinforcements, try these safe steps:
Step 1: Power Reset
Unplug the washer for 5 minutes to reset the control board, then plug it back in. Sometimes, the 4C code is just a sensor hiccup.
Step 2: Check Water Supply
Ensure both water supply valves are fully open and connected correctly.
Step 3: Inspect Hoses
Look for any visible kinks, bends, or leaks. Straighten them out and ensure there’s enough space behind the washer (at least 4 inches).
Step 4: Clean Filters
Remove the hose filters and rinse them under warm water.
Step 5: Test Again
Run a short cycle to see if water flows correctly.
If you still see the 4C/4E code, it’s likely time for professional washer repair.
