Samsung Washer Error Code 4E (or 4C) - Water Supply Error

Low Severity

Error code 4E (or 4C on newer digital models) indicates that the washing machine did not detect incoming water filling the drum within the 10-to-15-minute timeout window.

Appliance: Samsung Washing Machines

Estimated Time: 10-15 minutes

Tools Required: Pliers, bucket, small brush, flashlight

⚠ Common Symptoms & Observations

Washer stops shortly after cycle begins; humming sound near water inlet valves; drum remains dry or with very low water level; cycle timer freezes.

🔍 Root Causes for Code 4E / 4C

Home water supply valve is closed or partially turned off
water inlet hose is kinked or pinched
mesh filter screen inside the inlet valve is clogged with sediment/limescale
faulty water inlet solenoid valve
low household water pressure (below 20 PSI).

🔧 Step-by-Step DIY Troubleshooting & Fix Guide

Verify both cold and hot water faucets at the wall are fully turned counter-clockwise.

Power off the washer and unplug it. Carefully inspect the supply hoses behind the unit to ensure there are no sharp bends, kinks, or crimps.

Turn off wall valves, disconnect the hoses from the back of the washer, and inspect the plastic mesh filter screens. Remove them using needle-nose pliers and scrub under running water with a soft toothbrush to clear calcium scale.

Reconnect hoses securely, turn water supply back on, plug the washer in, and run a Quick Wash test cycle.

🔄 Master Reset Procedure for Samsung

Press the Power button to turn the unit off. Disconnect the main power plug from the wall outlet for 5 minutes to discharge the control board capacitors. Plug back in, press Power, and start a Rinse + Spin cycle.

Technician Tip: If the error code reappears immediately after a hard reset, the control board has detected an active electrical open circuit or failed component that requires physical inspection.
