Samsung Washing Machine: water supply error
What is this symptom?
Experiencing a water supply error on your Samsung washing machine? This issue, often signaled by error codes like 4E/4C, indicates trouble with water entering the drum. Common causes include blocked hoses, closed valves, or clogged filters. Addressing these problems promptly ensures your washer operates efficiently.
Possible Causes
Blocked, kinked, or improperly connected water supply hose
How to Identify: Inspect hose for visible kinks, bends, or obstructions; check if hose is firmly connected at both ends.
Part: Inlet water supply hose
Closed or low water supply valve / inadequate household water pressure
How to Identify: Verify the water supply tap is fully open; test water flow from the tap connected to the washer by disconnecting hose briefly.
Part: Water supply valve and home water supply
Clogged inlet filters or water valve screens
How to Identify: Remove and inspect inlet filter screens at hose connection for sediment or debris reducing flow.
Part: Inlet valve filter screens
Malfunctioning water inlet valve
How to Identify: Even with good pressure and open valves, no water flows or water does not stop, suggesting valve electrical/control failure.
Part: Water inlet valve
Faulty water level/pressure sensor
How to Identify: Machine fails to detect water level correctly, error persists despite water flow.
Part: Pressure/water level sensor
Control board or wiring fault (connector vibration or damage)
How to Identify: Error persists after all other checks; community reports of connector issues resolving similar errors.
Part: Main control board or wiring harness
