Whirlpool WTW5540SQ0 washer Parts

The Whirlpool WTW5540SQ0 washer has a 3.2 cu. ft. capacity. That capacity helps you estimate how much laundry you can wash per load and choose the right water level and cycle settings for best cleaning and spin-out.

How to use capacity in everyday loading

Capacity is a tub-volume rating, not a “number of items” guarantee. For the WTW5540SQ0, we recommend:

• Load items loosely so they can circulate through wash water.
• Mix large and small items to help balance the basket.
• Avoid packing items down; overloading reduces cleaning and can increase vibration.
• Use the correct load size or water level setting for the amount of laundry.
• Stop loading at about the top of the basket, not above it.

For model-specific loading guidance and cycle tips, use the WTW5540SQ0 washer user manual.

Quick reference: what 3.2 cu. ft. typically means

Load type	Typical examples	Best practice
Small	A few shirts, light items	Use a lower water level
Medium	Mixed everyday laundry	Distribute evenly around the agitator
Large	Towels or jeans (not packed)	Use a higher water level; keep items loose

Why it matters

Using the washer’s 3.2 cu. ft. capacity correctly helps prevent out-of-balance spinning, improves rinse performance, and reduces wear on key drive components like the agitator and basket drive system.

For the Whirlpool WTW5540SQ0 top-load washer, the most common issue we see is an unbalanced load that causes banging, walking, or poor spinning. In many cases, correcting how the load is distributed and making sure the washer is level fixes the problem without replacing parts.

Quick checks we recommend first

• Stop the cycle and redistribute items evenly around the basket (mix large and small items).
• Avoid overloading; clothes should move freely in the wash water.
• Confirm the lid is fully closed; this model will not agitate or spin with the lid open.
• Verify the washer is level and the front leveling feet are installed and tightened.
• Make sure shipping materials were removed (yellow shipping strap and pins) if the washer was recently installed.

When it is more than just an unbalanced load

If the washer is level and loads are balanced but it still won’t spin correctly or it stops mid-cycle, a failing lid switch is a common cause on many Whirlpool top-load designs.

• If the washer won’t spin with the lid closed, inspect the lid strike area and switch mounting.
• If the lid switch tests bad, replace the washer lid switch assembly WP8318084.

Symptoms and likely causes (at a glance)

What you notice	Most likely cause	What to do next
Loud banging during spin	Load off-balance, washer not level	Redistribute load; level the washer
Washer “walks”	Leveling feet not set, weak flooring	Re-level; move to sturdier floor if needed
Won’t spin with lid closed	Lid switch issue	Check/replace lid switch
Water splashes or leaks during fill/rinse	Off-balance load deflecting water, not level	Balance load; level washer

Why it matters

Running the WTW5540SQ0 while it is out of balance can increase vibration and wear on suspension components, the basket drive system, and the tub ring area. Fixing balance and leveling early helps prevent repeat problems.

For model-specific operating and troubleshooting steps, follow the WTW5540SQ0 washer user manual.

On the Whirlpool WTW5540SQ0 washer, the model number is printed on the model and serial number label located under the washer lid. Lift the lid and look along the top rim of the tub opening for the label.

Where to look (fast checklist)

• Unplug the washer or keep hands clear of moving parts
• Lift the lid fully
• Look for a sticker or metal tag that lists Model and Serial
• Check the underside of the lid and the top rim under the lid
• Wipe dust or detergent residue off the label so the characters are readable

What the label looks like

Most Whirlpool top-load washers like the WTW5540SQ0 use a single label that includes both numbers.

Item on label	What it’s used for	Example format
Model number	Matching parts and diagrams	WTW5540SQ0
Serial number	Identifying production run	Letters and numbers

Why it matters

Using the complete model number prevents ordering the wrong washer parts (for example, a lid switch assembly, drain pump, or water inlet valve that looks similar but does not fit). We use the model number to match the correct diagrams, manuals, and manufacturer-approved replacements.

If the label is hard to read

• Take a clear photo with flash and zoom in
• Copy the model number exactly, including all letters and numbers
• Use the model number when referencing the WTW5540SQ0 owner's manual
