Whirlpool WTW5521SQ0 washer Parts

The Whirlpool WTW5521SQ0 washer has a typical capacity of about 3.2 cu. ft., which is a common tub size for this style of top-load, direct-drive washer. For the exact rated capacity and load guidance for your specific unit, use the owner's manual.

How to use that capacity in real life

Capacity is most useful as a loading guide. In a top-load washer like the WTW5521SQ0, performance depends on leaving room for clothes to circulate.

• Load items loosely; do not pack or compress laundry
• Keep the load height at or below the top row of holes (if visible) in the basket
• Mix large and small items to balance the spin
• Use the correct water level (if your model has a selector)
• For bulky items, wash 1 to 2 pieces at a time (comforters, jackets)

Quick capacity reference

Capacity (cu. ft.)	Typical best for	Common overload symptom
~3.2	Everyday mixed loads, towels, jeans	Poor cleaning, out-of-balance spin
Smaller	Light loads, small households	Frequent multiple loads
Larger	Bulky bedding, big family loads	Less water per item if overloaded

Why it matters

When a washer is overloaded, it can struggle to agitate and spin correctly. That can lead to wet clothes at the end of the cycle, extra vibration, and faster wear on drive components such as the washer motor coupling 285753A and clutch 285785.

The most common Whirlpool washer problems are “won’t drain or spin,” “won’t start,” leaks, and excessive shaking. On the Whirlpool WTW5521SQ0, many of these symptoms trace back to basics like the lid being open, a clogged or incorrectly installed drain hose, or water inlet screens that need cleaning (see the owner's manual).

Most common symptoms and what usually causes them

• Won’t drain or spin (clothes still wet): lid not fully closed, drain hose clogged, drain hose installed too high (over 96 in.), or a failing drain pump
• Won’t start or seems “stuck”: timer not set to a cycle, household breaker/fuse issue, normal cycle pause, or lid switch not engaging
• Fills slowly or not at all: clogged inlet valve screens, kinked inlet hoses, hot/cold faucets not fully on
• Keeps filling or draining: drain hose positioned too low or sealed too tightly in the standpipe (needs an air gap)
• Shakes or walks: unbalanced or overloaded load, suspension wear

Quick checks we recommend first (WTW5521SQ0)

1. Confirm the lid is closed; this model will not agitate or spin with the lid open.
2. Check the drain hose height; the end of the hose should not be more than 96 in. (244 cm) above the floor.
3. Make sure the drain hose is not taped/sealed into the standpipe; it needs an air gap.
4. Turn off water and clean inlet valve screens; then reinstall hoses and check for leaks.
5. Reduce detergent if you see excess suds; oversudsing can affect draining and cycle performance.

Parts that commonly fix these problems

Symptom	Common fix	Example part for WTW5521SQ0
Won’t drain	Replace a weak pump	Washer drain pump WP3363394
Won’t spin/agitate	Lid switch not sensing closed lid	Washer lid switch assembly WP8318084
Agitator not moving properly	Worn agitator dogs	Agitator dog 80040
No spin, loud coupling noise	Worn motor coupling	Washer motor coupling 285753A

Why it matters

Drain, spin, and fill issues often look like major failures, but on a direct-drive top-load washer like the WTW5521SQ0, correct hose setup, proper loading, and a working lid switch prevent repeat breakdowns and help protect the drive system.

On the Whirlpool WTW5521SQ0 top-load washer, there is not a front-access drain filter like many front-load models. Drain issues are usually related to the drain hose setup or the drain pump, not a clean-out filter; use the owner's manual to confirm the drain and spin checks for this model.

What to check first (most common on this model)

• Make sure the lid is fully closed; this washer will not drain or spin with the lid open.
• Check the drain hose height; the hose end should not be more than 96 in. (244 cm) above the floor.
• Avoid siphoning; do not push too much hose into the standpipe (typically keep it to 8 in. (20.3 cm) inside).
• Keep an air gap; the hose should be secure but not sealed tight in the standpipe.
• Look for kinks or clogs in the corrugated drain hose.

If the washer won’t drain: likely parts and symptoms

If the hose and installation are correct, the next most common cause is a failing or blocked drain pump.

Symptom	What it usually points to	What to do next
Hums but won’t drain	Pump jam or failing	Inspect pump inlet/outlet for debris; replace pump if needed
Drains slowly	Partial blockage in hose or pump	Clear restriction; verify standpipe/laundry tub setup
Won’t spin and won’t drain	Lid switch issue or drain problem	Confirm lid switch operation; then check pump and hose

If you need the pump for this model, use the washer drain pump WP3363394.

Why it matters

A missing air gap or an incorrect drain hose height can make the cycle seem “stuck” because the washer can keep filling and draining (siphoning). A weak drain pump can also prevent proper spin because the tub must drain before high-speed spin.
