Samsung 4CWater supply error — not filling (4E)

A Samsung 4C (older displays show 4E) means the washer started a cycle but not enough water reached the tub in time. Nine times out of ten on the bench it's the boring stuff — a closed supply valve, a kinked or frozen inlet hose, or a clogged inlet screen — not a broken part. Rule those out (all free) before you buy anything; the water inlet valve is the part only if the water's on and the screens are clear.

🔧 From our repair bench: Check the free stuff first: turn both hot AND cold faucets fully on, and pull the inlet hoses to clear the little mesh screens where they meet the machine.

🐜 Straight talk: this points you at the likely cause — it's not a guarantee, and every machine is different. Cut the power (and shut off gas or water) before you touch anything, test to confirm the part is actually bad before you buy, and if it's beyond you, get a pro. No shame in that.

The Tools to Test + Fix With

You don't need a shop full of tools — you need these. The multimeter is the one that pays for itself the first time it stops you buying the wrong part on a fault code.

No part — open the valves & clear the screens

Both faucets full-on, hoses not kinked/frozen, and the mesh inlet screens rinsed clear. This clears most 4C codes for free.

Can you fix it yourself?

Safe to Try · Know the Risk · Call a Pro

General guidance, not professional advice. Always unplug the appliance (or shut off the gas/water) before you check anything. If it feels beyond you, that's exactly when to get a pro.

✅ Safe to try yourself

  • Turn both the hot and cold supply faucets fully open.
  • Unkink the fill hoses; in winter, check they aren't frozen.
  • Unscrew the hoses and rinse the small mesh inlet screens — a common silent clog.

⚠️ Doable — know the risk

  • Water inlet valve swap — doable with the power off and water shut off; expect a little water in the hoses.

🛑 Call a pro — don't touch this

  • A wiring/connector fault to the valve you can't trace, or a main-board fault.
Is it worth fixing?

The Honest Call

Almost always a cheap fix. The free checks clear most 4C codes; the valve is $25–55 and 30 minutes. No reason to replace a washer over a fill error.

FAQ

People Also Ask

What does 4C mean on a Samsung washer?
A water-supply error — the washer didn't fill with enough water in time. Older Samsung displays show it as 4E. Usually a closed valve, kinked/frozen hose, or clogged inlet screen; sometimes a bad water inlet valve.
How do I fix a Samsung 4C code myself?
Turn both faucets fully on, straighten the fill hoses, then unscrew the hoses and rinse the mesh inlet screens. If water's flowing and screens are clear but it still won't fill, replace the water inlet valve.
Is 4C the same as 4E?
Yes — same water-supply fault, just shown differently. Newer Samsung panels use 4C, older ones use 4E.
