Quick answer

First, ensure the water supply valves are fully open and the hoses are connected securely. Check for kinks in the hoses and inspect the water inlet filter for clogs. If the issue persists, run a diagnostic or consult the user manual for error codes.

Step-by-step troubleshooting

Check Water Supply Valves
Do: Locate the water supply valves under the washer and ensure they are fully open.
Observe: Valves are open and not partially closed.
Means: Valves are properly open if the handle is parallel to the pipe.
Next: If valves are open, move to the next step.
Inspect Water Hoses
Do: Check the inlet and outlet hoses for kinks, cracks, or blockages.
Observe: Hoses are straight, intact, and securely connected.
Means: Kinks or damage can restrict water flow.
Next: If hoses are clear, proceed to the next step.
Clean Inlet Filter
Do: Turn off the water supply. Use a screwdriver to remove the inlet valve filter and clean it with a cloth.
Observe: Filter is free of debris and mineral buildup.
Means: A clogged filter can prevent water from entering the washer.
Next: If the filter is clean, continue to the next step.
Test Water Inlet Valve
Do: Set the washer to a fill cycle and listen for a clicking sound from the inlet valve.
Observe: You hear a clicking sound, indicating the valve is receiving power.
Means: No sound may indicate a faulty inlet valve or wiring issue.
Next: If no sound is heard, check the wiring or replace the inlet valve.
Check for Error Codes
Do: Consult the user manual to interpret any displayed error codes related to water filling.
Observe: Error code corresponds to a specific issue (e.g., water supply problem).
Means: Error codes can pinpoint the exact cause of the problem.
Next: If an error code is present, address the specific issue indicated.
Run Diagnostic Mode
Do: Refer to the user manual for instructions on entering diagnostic mode to test the washer's functions.
Observe: Diagnostic mode identifies the component causing the water fill issue.
Means: This can confirm if the issue is with the inlet valve, water level sensor, or other components.
Next: If the diagnostic mode identifies a faulty part, replace it as needed.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Closed or partially closed water valves Water cannot flow into the washer if the valves are not fully open.	Common	Easy	None
Clogged inlet filter Mineral deposits or debris can block the filter, preventing water flow.	Common	Easy	Inlet valve filter (if replacement is needed)
Kinked or damaged water hoses Physical obstructions in the hoses restrict water flow to the washer.	Common	Easy	Water inlet hose (if replacement is needed)
Faulty water inlet valve The valve may not open properly due to electrical failure or clogging.	Sometimes	Medium	Water inlet valve
Malfunctioning water level pressure switch The switch may not detect the water level, causing the washer to stop filling prematurely.	Sometimes	Medium	Water level pressure switch
Blocked drain pump filter A clogged drain pump can cause water to back up and prevent proper filling.	Rare	Medium	Drain pump filter (if cleaning is needed)
Control board issue A faulty control board may not send the correct signals to the inlet valve.	Rare	Hard	Control board

FAQ

Why is my Samsung washer not filling with water even though the valves are open?

This could be due to a clogged inlet filter, kinked hoses, or a faulty water inlet valve. Check these components for blockages or damage.

How do I clean the inlet filter on my Samsung washer?

Turn off the water supply, locate the inlet valve, and use a screwdriver to remove the filter. Clean it with a cloth and reassemble it once clean.

What does error code 'U1' mean on my Samsung washer?

Error code 'U1' typically indicates a water supply issue. Check the water valves, hoses, and inlet filter for problems.

Can a faulty water level pressure switch cause the washer not to fill?

Yes, a malfunctioning water level pressure switch may prevent the washer from detecting the water level, causing it to stop filling prematurely.

Is it safe to replace the water inlet valve myself?

Yes, as long as you follow the manufacturer's instructions and ensure the power and water supply are turned off before starting the repair.
