On the covered Samsung washer platform, 4C, 1 4C, nF, 4E means not filling error: water is not entering the washer correctly. First, make sure both the hot and cold supply hoses are connected to the correct inlets, hot to hot and cold to cold, and are not bent or kinked.
Differential
Likely causes of “Samsung washer code 4C, 1 4C, nF, 4E”, and how to tell them apart
- 1
Supply hoses connected to the wrong inlets or bent
What separates it The washer stops with 4C, 4E or nF and no water enters the tub
How to confirm Samsung says hot must go to hot and cold to cold, and the hoses must not be bent or kinked
- 2
Water valves not fully open
What separates it The valves are only partly turned and the fill is slow or absent
How to confirm Open the valves completely and leave them open while the washer runs, as Samsung says
- 3
A drain hose pushed in too far or too little
What separates it The drain hose sits under 6 inches or over 8 inches down the pipe
How to confirm The drain hose should not be inserted less than 6 inches or more than 8 inches into the drain pipe
- 4
Debris blocking the inlet filters
What separates it Hoses and valves are fine and water still barely trickles
How to confirm Turn the valves off, disconnect the hoses and look inside the washer's connections for debris on the filters
- 5
A hot line that is not connected
What separates it The washer worked in summer and stopped when the weather turned cold
How to confirm Samsung says a washer with only a cold line will stop in cold weather even on Cold, because it mixes in hot water below 60 degrees F
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact characters shown on the display: 4C, 4E or nF
- Whether both the hot and cold hoses are connected
- Whether the code appears in cold weather only

ReversibleMake sure both the hot and cold supply hoses are connected to the correct inlets, hot to hot and cold to cold, and are not bent or kinked.
Correct only the documented fault domain
ReversibleSamsung's steps: if the hot line is not connected you will get an error when the washer tries to use hot water, even on cycles labeled Cold. Do not use Flood Safe hoses. Open the water valves completely and leave them open while the washer runs. Make sure the drain hose is inserted properly and is not kinked, no less than 6 inches and no more than 8 inches into the drain pipe, and do not remove the screw on the back that holds the drain hose against the washer (if the holder is missing, service is required).
Unplug the washer or flip its circuit breaker for 1 minute, restore power and try a cycle. Debris in the water supply is filtered before it enters the washer, and enough buildup blocks the water: to check, turn the supply valves off, disconnect the hoses from the back of the washer, look inside the connections and carefully remove and clean the filters, then open the valves fully again. If the code continues, Samsung says to request service from its Support Center.
Check both supply hoses
ReversibleMake sure the hot and cold hoses go to the correct inlets, are not bent, kinked or pinched shut, and are not Flood Safe hoses, which Samsung says not to use.
Open the valves
ReversibleOpen the water supply valves all the way and leave them open while the washer runs, since a half-open valve slows the fill enough to trigger the code.
Check the drain hose
ReversibleConfirm the drain hose is not kinked and sits between 6 and 8 inches down the drain pipe, and do not remove the screw at the back that holds the drain hose against the washer.
Power reset
ReversibleUnplug the washer or flip its circuit breaker for 1 minute, restore power and try a cycle.
Clean the inlet filters
ReversibleIf debris is suspected, turn the supply valves off, disconnect the hoses, look inside the washer's connections, carefully remove and clean the filters, and open the valves fully again after reconnecting.
