Samsung Samsung WA50R5400AW 5.0 cu. ft. Top Load Washer 4E1 Error Fix: Hot/Cold Water Lines Reversed

Error code 4E1 on the Samsung Samsung WA50R5400AW 5.0 cu. ft. Top Load Washer means: Hot/Cold Water Lines Reversed. The hot and cold water supply hoses are connected to the wrong inlets on the back of the washer. Hot water is entering the cold inlet and vice versa. Samsung washers detect this by measuring incoming water temperature against expected values. Swap the hoses — the red-marked inlet should receive hot water, and the blue-marked inlet should receive cold water. This can also appear if the water heater is not producing hot water.
