Samsung WA50T5300AC/US-01 washer Parts

On Samsung washers, NF1 typically points to a water fill problem (the washer is not filling as expected). On the Samsung WA50T5300AC series, the user manual lists fill-related codes like 4C/4C2; NF1 may appear on some displays or in some regions as a related “no fill” style code. See the WA50T5300AC user manual for the model’s official information-code list.

What to check first (most common causes)

• Confirm both water taps are fully open (hot and cold).
• Make sure the inlet hoses aren’t kinked, crushed, or frozen.
• Check that hoses are connected to the correct taps (hot to hot, cold to cold).
• Clean the mesh filters in the water inlet valves (sediment can restrict flow).
• Verify your home has adequate water pressure; this model family expects roughly 20 to 116 psi.

Quick troubleshooting steps for WA50T5300AC

1. Press Power to turn the washer off.
2. Unplug the washer for 1 minute, then plug it back in.
3. Run RINSE+SPIN to test filling.
4. If the code returns, clean the inlet mesh filters and retest.

Fill-code comparison (helpful when the display varies)

What you see on the display	What it usually means	What to do next
NF1	Fill problem (not filling)	Check taps, hoses, filters, pressure
4C	Water is not supplied	Same checks; clean mesh filters
4C2	Cold hose connected wrong (or cold supply issue)	Confirm cold hose is on cold tap

Why it matters

A fill error can stop the cycle to prevent poor washing results and protect components like the inlet valve and control system. Fixing the water supply issue early also helps prevent repeat interruptions and longer cycle times.

For the Samsung WA50T5300AC washer, the most common customer complaints we see are poor spinning (clothes still wet), draining problems, and excessive vibration or “walking” during spin. These issues are often caused by load balance, drain restrictions, or installation and leveling problems rather than a single failed part.

Most common symptoms (and what they usually point to)

• Clothes still wet at the end: unbalanced load, too-small load, oversudsing from non-HE detergent, or a drain restriction
• Won’t drain or drains slowly: kinked/clogged drain hose, standpipe height issue, or debris buildup
• Shakes or bangs during spin: washer not level, load not distributed, or unstable flooring
• Stops mid-cycle: lid not fully closed/locked, power issue, or the washer pausing to rebalance
• Error codes on the display: the washer is detecting a condition like fill, drain, or balance trouble

For model-specific operating and troubleshooting steps, follow the checkpoints and information codes in the WA50T5300AC user manual.

Quick checks we recommend first (WA50T5300AC)

• Re-distribute the load; mix large and small items to help balance
• Confirm the washer is level and all 4 leveling feet are firmly on the floor
• Verify the drain hose is not kinked and is installed at the correct height range
• Use HE detergent only and reduce detergent if you see excessive suds
• Run RINSE+SPIN to test draining and spinning without a full wash

Common issue-to-fix guide

What you notice	Most likely cause	Best first step
Wet clothes after cycle	Unbalanced load or oversudsing	Rebalance load; use HE detergent; try higher spin
Loud banging in spin	Not level or load clumped	Level the washer; spread items evenly
Drain error or standing water	Drain hose restriction/height	Check hose routing and standpipe height
Fill problems	Clogged inlet screens or low pressure	Clean inlet mesh filters; verify taps fully open

Why it matters

Spin, drain, and vibration problems can look like “major failures,” but they are often correctable setup or usage issues. Fixing those first can prevent repeat error codes, reduce wear on the drive system, and improve cleaning and drying time.

Your Samsung washer’s model number is printed on the appliance ID label; on WA50T5300AC units, it’s typically found under the lid opening around the tub rim or on the back of the cabinet. Match the full model number exactly when ordering parts or using the WA50T5300AC owner's manual.

Where to look on a top-load Samsung washer

Check these common label locations first:

• Under the lid, along the top edge of the tub opening (rim) or underside of the lid area
• On the rear panel of the washer cabinet
• Along the inside edge of the top panel near the lid switch area
• On the side of the cabinet near the back (less common)

What to write down (so parts fit)

Record the information exactly as shown on the label.

• Model number (example format: WA50T5300AC)
• Version code (often shown as two digits after the model, such as “/01”)
• Serial number (helpful for service and production changes)

Label item	Why it matters
Model number	Identifies the correct parts list and diagrams
Version code	Ensures the right revision of parts for your exact build
Serial number	Helps confirm production range when parts changed

Why it matters

Samsung washers can use different components across versions of the same model family. Using the exact model and version code helps us match the correct items like a lid lock, drain pump, or water inlet valve for WA50T5300AC.
