Samsung Washer Error Code 4E1 — Hot Water Supply During Cold Fill
What this means
The 4E1 error code indicates the washer detects water temperature above 70°C (158°F) entering during a cold-water cycle. This usually means the hot and cold water supply hoses are connected to the wrong inlet valves on the back of the washer. It can also occur if the household water heater is set extremely high and there is a mixing valve issue.
Alternate codes: 4C1
Step-by-step fix
3 stepsCheck the water supply hose connections
Turn off both water supply valves behind the washer. Check that the hot water hose (usually red or marked H) connects to the hot water inlet on the washer, and the cold water hose (usually blue or marked C) connects to the cold water inlet.
The hot and cold inlets are labeled on the back of the washer.
Swap hoses if reversed
If the hoses are swapped, disconnect them and reconnect them to the correct inlets. Turn the water supply back on and check for leaks.
Run a hand under the water from each valve before connecting to confirm which is hot and which is cold.
Run a test cycle
Start a cold-water cycle and let it fill. The error should clear if the hoses were the issue.
If the error persists with hoses correctly connected, the water inlet valve may be stuck open on the hot side.
When to call a professional
If hoses are correctly connected and the error persists, the water inlet valve assembly may need replacement. A technician can test the valve solenoids.
