Samsung WA422PRHDWR/AA-01 washer Parts

NF1 on a Samsung washer indicates a water fill problem: the washer is not sensing water entering the tub as expected during the fill portion of the cycle. On the Samsung WA422PRHDWR, this usually points to a supply, inlet screen, or water inlet valve issue; check the owner's manual for model-specific error details.

What to check first (fast fixes)

• Confirm both hot and cold water faucets are fully open.
• Make sure the fill hoses are not kinked, crushed, or frozen.
• Verify the hoses are connected to the correct ports (hot to hot, cold to cold).
• Check household water pressure; most washers need steady pressure to fill normally.
• Power reset: unplug the washer (or switch off the breaker) for 2 minutes, then retry.

Clean the inlet screens (common cause)

Sediment can clog the small screens where the hoses connect to the washer, restricting flow and triggering NF1.

• Turn off both water faucets.
• Remove the hoses from the washer.
• Carefully rinse or brush the inlet screens (do not puncture them).
• Reconnect hoses, turn water back on, and check for leaks.

When it’s likely a part problem

If the screens are clean and water supply is good, NF1 often comes from a failed inlet valve or a control issue.

Symptom	Most likely cause	What we recommend
No water enters at all	Failed inlet valve, no supply	Test supply, then replace valve if needed
Slow fill on one temperature	Clogged screen or weak valve solenoid	Clean screens; replace valve if flow stays weak
Intermittent fill, error returns	Wiring/control sensing issue	Inspect connections; consider control diagnosis

For this model, the fill valve is commonly replaced as the Samsung washer water inlet valve DC97-15459H.

Why it matters

A washer that cannot fill correctly can stop mid-cycle, rinse poorly, and strain components like the drain pump and electronic control as the machine repeatedly tries to correct the water level.

Ordering the right replacement part

We recommend matching parts by the full model number WA422PRHDWR and comparing the part listing details before ordering. You can order parts from the list for this model, or search by model on Sears PartsDirect.

The Samsung WA422PRHDWR top-load washer has a 4.2 cu. ft. capacity, which is considered a large-capacity tub for everyday family loads. For cycle and load-size guidance specific to this model, use the WA422PRHDWR owner's manual.

What 4.2 cu. ft. means in real laundry terms

A 4.2 cu. ft. washer typically handles bulky and mixed loads well when you load it correctly.

• Large mixed load of clothes (everyday family laundry)
• Several bath towels in one load
• A comforter or bulky item (best on a bulky/bedding cycle when available)
• Jeans and heavier items (balance the load around the tub)

Load tips to get the best results

Overloading is the most common reason for poor cleaning, out-of-balance spinning, and long cycle times.

• Load items loosely; do not pack them down
• Keep the load level around the washplate area, not heaped to one side
• Mix large and small items to help balance during spin
• Use the correct water level or load-size setting for the fabric type
• If the washer bangs or walks, re-distribute the load and re-start the spin

Quick capacity comparison

Washer capacity	Typical use case	What you notice most
3.5 to 3.9 cu. ft.	Medium loads	More loads per week
4.2 cu. ft. (WA422PRHDWR)	Large everyday loads	Fewer loads, better for towels
5.0+ cu. ft.	Extra-large/bulky focus	More room for comforters

Why it matters

Capacity affects how much you can wash at once, but performance depends just as much on proper loading, cycle selection, and a stable, level installation. If your washer struggles to fill, drain, or spin, we recommend checking common wear items and ordering replacements from the parts list on this page or searching by model on Sears PartsDirect.

A Samsung top-load washer like model WA422PRHDWR typically lasts 10 to 14 years with normal household use and basic maintenance. Lifespan depends most on load size, leveling, water quality, and keeping the drain system clear; see the WA422PRHDWR owner's manual for care guidance.

What affects lifespan the most

• Overloading (heavy blankets, repeated oversized loads) increases stress on the drive system and suspension.
• Out-of-balance loads speed up wear on the tub support and suspension.
• Poor draining (coins, lint, small items) strains the pump and can cause repeated drain errors.
• Hard water and excess detergent can leave buildup that impacts performance over time.
• Improper leveling increases vibration and can shorten component life.

Maintenance that adds years

• Keep loads to a reasonable size and distribute items evenly.
• Level the washer and re-check if it starts vibrating; a worn washer leveling leg DC61-01722B can make balancing difficult.
• Periodically inspect and clear the drain path; if draining slows or you see debris, check the washer pump coin trap DC61-03385A.
• Use the correct detergent amount and run periodic cleaning cycles.
• Address new noises early; a failing pump often starts as intermittent grinding or humming.

Common wear items and what they impact

Symptom	Likely wear area	Example part for WA422PRHDWR
Won’t drain, drains slowly	Drain system	Washer drain pump DC31-00054D
Excessive shaking or banging	Suspension/leveling	Washer suspension rod and spring assembly DC97-16350C
Won’t fill or fills slowly	Water inlet	Samsung washer water inlet valve DC97-15459H

Why it matters

Knowing the 10 to 14 year average helps you decide whether to repair or replace. If your WA422PRHDWR is within that range, replacing a targeted part (pump, inlet valve, suspension) often restores reliable performance.
