Washer will not start wash cycle and displays 4C or 4E; drum does not fill with water or fills very slowly.

Safety first: Unplug the washer and turn off both hot and cold water supply valves before working on hoses or valves.

• Check water supply: Verify both wall faucets are fully open and that other fixtures in the home have normal pressure.
• Inspect hoses: Pull the washer forward, ensure inlet hoses are not kinked, crushed, or leaking. Straighten or replace as needed.
• Clean inlet filters: Turn off water, disconnect hoses from the back of the washer. Inside the water inlets you will see small mesh screens. Gently pull them out with needle-nose pliers and rinse under running water to remove sediment. Reinstall screens and reconnect hoses firmly.
• Test fill: Restore water and power, run a quick wash to see if filling improves.
• If still failing: The internal water inlet valve assembly may be defective. This requires removing the top cover, disconnecting wiring and hoses, and installing a new Samsung-compatible valve. If you are not comfortable with plumbing and electrical work, contact a technician.
