Samsung Samsung WF45R6100AW 4.5 cu. ft. Front Load Washer 4E Error Fix: Water Supply Error

Error code 4E on the Samsung Samsung WF45R6100AW 4.5 cu. ft. Front Load Washer means: Water Supply Error. The washer is not detecting water entering the tub, or water is filling too slowly. The most common cause is closed water supply valves — verify both hot and cold valves behind the washer are fully open. Check for kinked supply hoses. Clean the inlet valve screens (small mesh filters at the back of the washer where the hoses connect) — mineral buildup can block water flow. Do not use flood-safe hoses as they can trip and block flow. If the valves and hoses are fine, the water inlet valve solenoid may have failed.
