Understanding the 4C Error on Samsung Washing Machines
If your Samsung washing machine suddenly flashes a mysterious “4C” error code, don’t panic. It’s not some cryptic hacker message or a sign that your laundry has entered an alternate dimension. It simply means your machine is having a water intake issue — essentially, it’s thirsty but can’t get a drink.
The 4C error indicates that the washer is not filling with water as it should. This can happen because of a kinked hose, a clogged filter, or even a faulty valve. Sounds simple enough, right? But like a suspense thriller, multiple culprits could be involved. Let’s dive deeper into the mysteries and how to solve them.
Common Causes Behind the 4C Error
- Kinked or Blocked Water Inlet Hose: A hose bent like a pretzel or clogged with debris cuts off water flow.
- Closed or Partially Open Water Supply Valves: Sometimes the simplest reasons are overlooked—make sure your taps are fully open.
- Dirty Mesh Filters: Small screens inside the hose or washer inlet can get clogged with minerals and grime over time.
- Low Water Pressure: If your home’s water pressure is weak (below 0.5 bar), your washer will struggle to fill.
- Faulty Water Inlet Valve: If all else fails, the electro-mechanical valve that lets water in might be broken and require replacement.
Step 1: Check and Open Your Water Supply Valves Fully
Let’s start at square one. Head behind your washing machine and locate the water supply valves. These are usually the two taps controlling hot and cold water flow to your machine.
Make sure both are turned all the way open to provide uninhibited water flow. Sometimes, during plumbing repair or accidental nudges, they get partially closed. Give them a good quarter to a half turn if needed. No shame in the basics.
Without water trying to rush in, your washing machine will complain with the 4C code.
Step 2: Inspect and Straighten Water Inlet Hoses
Next, check the hoses that connect your water supply to the washing machine’s back. These flexible tubes can get twisted or kinked behind the machine, especially if it’s been moved or shoved close to the wall.
A hose bent sharply can choke off water flow, triggering that dreaded 4C error. Gently straighten any bends and ensure the hoses aren’t tangled or crimped.

Step 3: Clean the Mesh Filters in the Water Inlet Hose and Washer
Now, brace yourself as we get to one of the most common culprits — clogged mesh filters. These are tiny screens located at the water inlet hose ends and inside the washing machine where the hoses connect.
Over time, they collect mineral deposits, sediment, and gunk that block water flow.
Here’s how to clean them:
- Turn off the water supply valves.
- Disconnect the water hoses from both the wall supply and the washing machine inlet.
- Using your fingers or a pair of tweezers, carefully remove the small mesh filter screens from the hose ends and the washing machine inlets.
- Rinse the filters thoroughly under running water to dislodge deposits and debris.
- Check the hose openings and washing machine inlet ports for any remaining grime and wipe them clean.
- Reinstall the mesh screens and reconnect the hoses tightly to avoid leaks.
A clean filter often fixes the 4C error by restoring proper water flow. This quick maintenance step saves many a repair call and is well worth the effort.

Step 4: Check the Detergent Dispenser for Blockages
You’d think detergent is innocent, but if the dispenser drawer is clogged or blocked, it can obstruct water flow during the wash cycle.
Remove the detergent drawer and rinse it carefully under warm water, clearing out any detergent build-up or moldy gunk.
Once squeaky clean, slot it back in. This simple step might not be the first thing you’d think to try, but it’s surprisingly effective in some cases.
Step 5: Perform a Power Reset to Clear Error Codes
Sometimes electronic gremlins just need a reboot. Unplug your washing machine from the power outlet for about 5 minutes. This short nap resets the machine’s control board and can clear lingering error codes.
After plugging it back in, watch to see if the 4C error code disappears and if your washer fills water properly again.
If magic doesn’t happen, it’s time to look deeper.
Step 6: Consider Water Pressure and Valve Replacement
Your washing machine wants a steady shower of water with pressure between approximately 0.5 and 8 bar. If your home’s pressure is weak—think of trying to shower with a garden hose on low setting—you’ll see error codes like 4C.
You can test your home’s water pressure with a pressure gauge or check if other taps are showing signs of low water flow.
If water pressure isn’t the issue, the water inlet valve inside the washing machine could be faulty. This valve controls water entry and can fail electrically or mechanically over time, especially if clogged with minerals.
Replacing it typically involves:
- Unplugging the washing machine.
- Disconnecting water hoses and removing the back panel.
- Identifying, removing, and replacing the inlet valve.
- Reassembling and testing the machine.

Pro Tips from the Laundry Trenches
- Regularly check hoses and filters every 6 months to keep water flowing freely.
- If you live in an area with hard water, consider installing a water softener to reduce mineral buildup.
- Before replacing parts, always run a diagnostic cycle on your machine if it has the function; it can provide more insight.

When to Call the Pros
If you’ve tried all these steps and your Samsung washing machine keeps flashing 4C like an SOS flare, your best bet is to contact a trusted repair technician. Particularly if you suspect the water inlet valve is toast, or there’s an electrical fault.
DIY is empowering, but knowing when to hand over the reins ensures your machine and laundry stay happier longer.
In Summary: Making Peace with the 4C Error
The 4C error on your Samsung washing machine is basically it telling you, “Hey, I’m not getting water.” Most often, that’s a household plumbing hiccup—blocked hoses, clogged filters, or stubborn valves.
By methodically checking water supply valves, straightening or replacing hoses, cleaning filters, and resetting the machine, you can usually solve the issue yourself without dialing a repair hotline.
Keep these troubleshooting tips handy, and next time that 4C flashes, you’ll be ready to fix it faster than you can say “Laundry day saved!”
