Samsung Washer 4C Error
What it means
The 4C error (shown as 4E on some older Samsung washers) means the washer is not filling with water correctly. The machine didn't receive enough water — or any water — within the expected time. It's almost always a water-supply problem like a closed tap, a kinked hose, or a clogged inlet filter, and it's usually a quick DIY fix.
Common causes of the 4C error
- Water supply tap (faucet) not fully turned on
- Kinked, bent, or crushed water inlet hose
- Clogged mesh filter screen in the inlet hose or valve
- Low household water pressure
- Frozen water line in cold weather
- Faulty water inlet valve (less common)
How to fix the Samsung Washer 4C error
- 1Unplug the washer firstFor safety, disconnect the washer from power before checking hoses and valves, especially if you'll be moving the machine.
- 2Open the water taps fullyCheck that both the hot and cold water taps behind the washer are turned on all the way. Partially open valves restrict flow and trigger 4C.
- 3Straighten the fill hosesInspect the water inlet hoses for kinks, bends, or crushing behind the machine and straighten them so water can flow freely.
- 4Clean the inlet mesh filtersTurn off the taps, unscrew the fill hoses from the back of the washer, and use needle-nose pliers to pull out the small mesh filter screens. Rinse away any debris or mineral buildup, then reinstall them and reconnect the hoses snugly.
- 5Reset and testPlug the washer back in and start a rinse/spin or short cycle to confirm it fills normally and the 4C error is gone. If it persists, unplug for 5 minutes to fully reset the control board, then retry.
🧰 When to call a professional
If the taps are open, the hoses are clear, and the filters are clean but 4C keeps returning, the water inlet valve or control board may have failed. That's an internal repair best handled by an appliance technician.
Samsung 4C error — FAQ
What does the 4C code mean on a Samsung washer?
It means the washer isn't getting water in time — a water-supply issue. Older models show this same fault as 4E.
Can I fix the Samsung 4C error myself?
Usually yes. Most 4C fixes are simple: open the water taps, unkink the hoses, and clean the inlet mesh filters. No special tools are needed beyond pliers.
Why does 4C show up when my water is on?
Even with the taps open, a clogged inlet filter, a kinked hose, or low water pressure can starve the machine of water and trigger 4C. Clean the filters and check the hose path first.
