What Does Error Code SYMPTOM‑WONT‑FILL Mean?

Error SYMPTOM‑WONT‑FILL on your Samsung Washing Machine means: The SYMPTOM‑WONT‑FILL code appears when the washer detects that the tub is not receiving the expected amount of water during a fill cycle. The machine pauses, displays the error, and refuses to start, leaving laundry stuck in a dry drum.

What You'll Need

🔧 Tools

Phillips #2 screwdriver
T20 Torx screwdriver
Flat‑head screwdriver
Multimeter (set to AC voltage and continuity)
Needle‑nose pliers

🛒 Parts

Water inlet valve (front‑loading models)
Water inlet hose
Water level pressure switch

How to Fix Error SYMPTOM‑WONT‑FILL — Step by Step

1

Power reset – the 60‑second check

Unplug the washer or turn off the dedicated circuit breaker for at least 60 seconds. This forces the electronic control board to reboot and clears any transient logic errors. After the pause, plug the unit back in and start a quick‑wash cycle. If the error disappears, the problem was a momentary glitch; otherwise continue.

💡 Pro Tip: Leave the door open while the unit is unplugged to let any residual charge drain from the control board.
2

Verify water supply and hose condition

Locate the hot and cold inlet hoses at the back of the machine. Make sure both supply valves are fully open. Detach each hose, inspect the mesh filter on the valve for kinks or debris, and clean with a soft brush if needed. Re‑attach the hoses, tighten the clamps, and turn the water back on. Watch for a steady stream into the tub.

💡 Pro Tip: If water drips slowly, soak the filter in warm, soapy water before reinstalling.
3

Test the water inlet valve electrically

Turn off power at the breaker and remove the rear access panel (four Phillips #2 screws). Locate the inlet valve—two solenoid coils with a plastic connector. Disconnect the connector and label it with masking tape. Set the multimeter to continuity (or resistance) and place the probes on the two terminals of each coil. A healthy coil reads about 20‑30 Ω; an open circuit shows infinite resistance. Replace the valve if either coil is out of range.

💡 Pro Tip: Take a photo of the connector before removal to avoid wiring errors.
4

Check the voltage reaching the inlet valve

Restore power (exercise extreme caution—live voltage). Set the multimeter to AC voltage and probe the two terminals of the inlet valve while the washer attempts to fill. You should see roughly 120 V in North America or 230 V elsewhere. No voltage indicates a problem upstream, most often a faulty fill relay on the main control board.

💡 Pro Tip: If you are not experienced with live electrical work, discontinue and seek professional assistance.
5

Inspect the water‑level pressure switch

The pressure switch monitors tub water level via a thin rubber hose attached to the outer drum. Disconnect the hose, blow gently to clear any blockage, and re‑attach. With the washer off, set the multimeter to continuity and press the test button (or manually apply pressure to the hose). The switch should close at low pressure and open at high pressure as specified in the service manual. Replace the switch if it stays permanently open or closed.

💡 Pro Tip: Replace a cracked or water‑soaked hose; it can cause false low‑pressure readings.
6

Replace the faulty component

If the inlet valve failed the continuity test or showed no voltage, order the correct part for your model and install it. Remove the mounting screws, pull the valve out, disconnect the water lines, and mount the new unit. Re‑connect the electrical connector, tighten hose clamps, and re‑assemble the rear panel.

💡 Pro Tip: Double‑check that the new valve’s connector matches the old one; some Samsung models use a 3‑pin connector versus a 2‑pin.
7

Run a full diagnostic cycle

Many Samsung washers have a hidden diagnostic mode. Press and hold the Spin and Soil‑Level buttons while turning the dial to ‘Spin.’ Select the fill test; the display should read “FILL OK.” If the error returns, the control board’s fill relay may be defective and will likely need professional service.

💡 Pro Tip: Write down any additional error codes that appear; they help the technician pinpoint the exact fault.

When to Call a Professional

If you measure no voltage at the inlet valve despite the water supply being fully open, the fill relay on the main control board is probably bad and should be serviced by a qualified technician. Also call a professional if the washer continues to display SYMPTOM‑WONT‑FILL after you have replaced both the inlet valve and pressure switch, as the board itself may need replacement.

Diagnostic Flowchart — SYMPTOM‑WONT‑FILL

The SYMPTOM-WONT-FILL error code on your Samsung washing machine can be frustrating, especially when you’re in the middle of a laundry cycle. This error occurs when the washer detects that the tub is not receiving the expected amount of water during a fill cycle. The machine pauses, displays the error, and refuses to start, leaving your laundry stuck in a dry drum.

What SYMPTOM-WONT-FILL Actually Means

The SYMPTOM-WONT-FILL error code is a symptom-specific code that indicates a problem with the washer’s ability to fill with water. This code is often related to issues with the water inlet system, which includes the water inlet valve, inlet hoses, and pressure switch. When the washer’s control board detects that the tub is not filling with water as expected, it displays the SYMPTOM-WONT-FILL error code and pauses the cycle.

The water inlet valve is the primary component responsible for controlling water flow into the washer. The pressure switch, on the other hand, monitors the water level in the tub and sends signals to the control board. If either of these components fails or malfunctions, the washer may not fill with water properly, resulting in the SYMPTOM-WONT-FILL error code.

Quick Checks Before You Repair

Before calling a professional or attempting any repairs, perform these quick diagnostic checks:

Power cycle: Unplug the washer or turn off the dedicated circuit breaker for 60 seconds. This simple reset may resolve the issue if it’s caused by a temporary glitch.
Verify water supply: Ensure that the water supply is turned on and that the inlet hoses are properly connected to the washer and the water supply lines.
Check inlet hoses: Inspect the inlet hoses for kinks, blockages, or damage. Make sure they are securely connected to the washer and the water supply lines.

Probable Causes, Most Likely First

Here are the common causes of the SYMPTOM-WONT-FILL error code, ranked by likelihood:

1. Faulty Water Inlet Valve

Description: The water inlet valve controls water flow into the washer. A faulty valve may not open or close properly, preventing the washer from filling with water.
How to verify: Test the water inlet valve electrically using a multimeter. Check for continuity and ensure that the valve is receiving the correct voltage.
Fix difficulty: Medium
Cost: $50-$150 (part number: DC64-02773A)

2. Clogged or Kinked Inlet Hoses

Description: Clogged or kinked inlet hoses can restrict water flow into the washer, causing the SYMPTOM-WONT-FILL error code.
How to verify: Inspect the inlet hoses for kinks, blockages, or damage. Check the water supply lines for any blockages or restrictions.
Fix difficulty: Easy
Cost: $0-$50 (depending on the hose replacement)

3. Faulty Pressure Switch

Description: The pressure switch monitors the water level in the tub and sends signals to the control board. A faulty pressure switch may not detect the water level correctly, causing the SYMPTOM-WONT-FILL error code.
How to verify: Test the pressure switch electrically using a multimeter. Check for continuity and ensure that the switch is receiving the correct voltage.
Fix difficulty: Medium
Cost: $50-$150 (part number: DC64-02774A)

4. Control Board Issues

Description: In some cases, the control board may be faulty, causing the SYMPTOM-WONT-FILL error code.
How to verify: Check the control board for any signs of damage or wear. Test the board electrically using a multimeter.
Fix difficulty: High
Cost: $100-$300
