Whirlpool WTW5520SQ0 washer Parts

The Whirlpool WTW5520SQ0 washer is a standard, full-size top-load design; washers in this class are typically about 3.0 to 3.5 cu. ft. For the exact basket capacity and the correct load sizing guidance, use the specifications and loading section in the WTW5520SQ0 owner's manual.

Typical capacity range for this washer type

Most Whirlpool direct-drive, top-load washers like the WTW5520SQ0 fall into a mid-size capacity range. Use this as a practical guide for load planning:

• Small load: a few shirts and light items
• Medium load: mixed everyday laundry (jeans, tees, underwear)
• Large load: several towels; avoid packing tightly
• Bulky items: wash one at a time when possible to prevent imbalance

How to load it correctly (prevents spin and cleaning problems)

Correct loading matters more than the exact cubic feet number because it affects agitation, drain, and spin performance.

• Load items loosely; do not press them down
• Distribute items evenly around the basket
• Keep heavy items (towels, jeans) balanced with similar items
• Select the right cycle and water level (if your model has a selector)
• If the agitator slips or “ratchets,” check wear items such as the agitator dog 80040

A Whirlpool washer like model WTW5520SQ0 typically lasts 10 to 14 years with normal household use. Consistent care matters most; following the operating and maintenance instructions in the WTW5520SQ0 owner's manual helps you get the longest service life.

Typical lifespan: what to expect

Most washers fall into a predictable range based on design and usage.

Washer type	Typical life expectancy	What most often shortens life
Top-load (like WTW5520SQ0)	10 to 14 years	Overloading, out-of-balance spinning, poor draining
Front-load	About 9 to 12 years	Seal/odor issues, heavy use, poor maintenance

What extends the life of a WTW5520SQ0 washer

We see the longest-lasting Whirlpool top-load washers when these basics are followed:

• Load to the top of the basket loosely; do not pack clothes down
• Use the right amount of detergent; too much can leave residue and stress the drain system
• Keep the washer level to reduce vibration and wear on suspension parts
• Use the correct water temperature for the fabric and soil level
• Check pockets and remove heavy items that can damage the basket or agitator
• Address small issues early (leaks, burning smell, slow drain) before they become major repairs

Parts that commonly affect longevity

When a washer starts slipping, not agitating, not draining, or not spinning, these are common wear items for this model:

• Agitator dog 80040 (worn dogs can cause weak or no agitation)
• Washer motor coupling 285753A (a common direct-drive wear part that can stop agitation/spin)
• Washer drain pump WP3363394 (clogs or pump wear can cause slow or no drain)
• Washer lid switch assembly WP8318084 (can prevent spin/drain if the switch fails)

Why it matters

A washer near the 10 to 14 year mark can still be a great candidate for repair if the tub and cabinet are in good shape. Replacing a few high-wear parts is often the difference between a noisy, unreliable washer and one that runs smoothly again.

The most common problems we see on Whirlpool washers like model WTW5520SQ0 are not draining/spinning, not agitating, and leaks. On this direct-drive top-load design, those symptoms often trace back to a lid switch issue, a drain restriction or pump problem, or a worn drive component.

Most common symptoms and what usually causes them

• Washer will not spin or agitate: lid not fully closed, or a failed lid switch; see washer lid switch assembly WP8318084.
• Washer will not drain: clogged drain hose, drain hose installed too high, or a failing pump; see washer drain pump WP3363394.
• Washer agitates poorly or makes a ratcheting sound: worn agitator dogs; see agitator dog 80040.
• Washer stops mid-cycle: normal pause in some cycles, overloaded load, or intermittent lid switch.
• Washer will not fill or fills slowly: clogged inlet valve screens, kinked inlet hose, or faucets not fully open.

Quick checks we recommend first (WTW5520SQ0)

These steps match common troubleshooting guidance for this style of Whirlpool washer; details and safety notes are in the owner's manual.

• Confirm the washer is plugged into a grounded 3-prong outlet (no extension cord).
• Make sure the timer knob is aligned to a cycle; turn slightly to the right and pull to start.
• Verify hot and cold faucets are on and inlet hoses are not kinked.
• Clean water inlet valve screens (turn water off first).
• Check the lid is fully closed; this washer will not agitate or spin with the lid open.
• Inspect the drain hose for clogs and confirm the drain height is 96 in. (244 cm) or less.

Common “problem to part” match-up

What you notice	Most likely area to check	Part example on this model
Won’t spin, won’t agitate	Lid switch circuit	WP8318084
Won’t drain, clothes still wet	Drain path or pump	WP3363394
Agitator slips or doesn’t move clothes well	Agitator dogs/agitator	80040
Spins weakly or intermittently	Drive coupling or clutch	285753A or 285785

Why it matters

Drain and spin problems can leave clothes soaking wet and can strain the drive system. Catching a simple cause (lid not closing, clogged screens, drain hose too high) can prevent unnecessary part replacement and reduce wear on the motor and clutch.
