Samsung Washer 4C Error: Water Not Filling and How to Fix It

4C on a Samsung washer means water is not entering the washer correctly. Samsung’s checks, in order: hoses on the right inlets with no kinks, both water valves fully open, the drain hose 6 to 8 inches into the drainpipe, a one-minute power reset, then clean inlet filters. If 4C continues, request service.

Samsung shows the same fault as 4E, nF or 1 4C depending on the model. A different code from the same family, 4C2, means the hoses are swapped; that one is covered below.

Which water code do you have?

If your code is in the first row, carry on below.

Samsung’s five checks

1. Hoses on the right inlets, not kinked

Pull the washer out. Hot goes to hot and cold to cold (Samsung says red to red, blue to blue), and neither hose should be bent sharply or crushed against the wall. Samsung also says not to use Flood Safe hoses.

2. Both water valves fully open

Turn each faucet all the way open. A valve shut for a vacation, or closed by a plumber, is the simplest cause of a fill code.

3. Drain hose 6 to 8 inches into the pipe

This sounds like a drain problem, but it causes fill codes. Samsung says to insert the drain hose 6 to 8 inches into the drainpipe. Pushed in deeper, water can siphon out while the washer fills. Samsung’s drain guide adds that the hose should not be sealed airtight into the pipe, and its end should sit between 18 and 96 inches above the floor (24 to 35 inches for a sink).

4. Power off for one minute

Unplug the washer, or switch off its breaker, for one minute, then restore power and try again. Samsung lists this step for 4C and most other codes.

5. Clean the inlet filters

Samsung says to disconnect the hoses, check the connections for debris and clean the filters if needed. The filters are small mesh screens in the inlets on the back of the washer, where the hoses screw on. Rinse them under a tap, refit them, reconnect the hoses, turn the water on and check for drips before you plug the washer in.

4C2: the hoses are swapped

Samsung lists 4C2, 4E2, CE, 14C2 and nF1 as a separate fault: the water from the cold supply is extremely hot. The fix is to connect cold to cold and hot to hot. Samsung says this code does not mean service is needed.

When 4C means a part

If water reaches the washer freely, the hoses and filters are clean and 4C keeps coming back, Samsung says to request service. Samsung’s code page does not name a part. The part that lets water into the washer is the water inlet valve, which sits inside the cabinet with wiring attached, so it is a technician job unless you are experienced and the washer is unplugged.

If a technician confirms the valve, order the one listed for your model number (how to find it).

Other brands use their own letters for the same kind of fault: LG shows IE, and Whirlpool front-load washers show F8 E1 (Whirlpool codes). For the other Samsung washer codes, see the Samsung washer code list. If the washer fills but stops with suds, the code is SUd.
