Whirlpool WTW4105SW0 washer Parts

The most common Whirlpool washer problems (including the Whirlpool WTW4105SW0) are draining or spinning issues (clothes stay wet), water leaks, and “won’t start” symptoms. These often trace back to load balance, hoses, lid lock problems, or drive system wear such as a damaged pulley.

Most common symptoms we see

• Won’t drain or won’t spin: water left in the tub, wet clothes at end of cycle
• Leaking: dripping at the back, under the washer, or at hose connections
• Won’t start or stops mid-cycle: lid not locking, cycle won’t engage
• Loud noise in spin: grinding, squealing, or thumping
• Poor wash action: clothes not moving well, heavy items staying in one spot

Quick checks that fix many “common problems”

1. Redistribute the load (especially bulky items); run a Drain/Spin cycle again.
2. Confirm the lid closes and locks; a failed lid lock can prevent spin.
3. Inspect fill hoses and drain hose routing for drips, cracks, or loose connections.
4. Check for rubbing or grinding noises from the drive area under the washer.
5. Power reset: unplug for 2 minutes, then restart a normal cycle.

Parts that commonly solve these symptoms on WTW4105SW0

If the basic checks do not help, these model-matched parts are common fixes:

Symptom	What often failed	Example part for this model
Won’t spin, abnormal noise	Drive pulley worn or loose	Whirlpool washer drive pulley W10721967
Won’t start or won’t spin	Lid lock not engaging	Latch, lid lock assembly W11513248
Won’t shift between agitate and spin	Shift actuator issue	Actuator, shift W11481722
Weak start, humming	Start/run capacitor	Washer start/run capacitor W11395618

Why it matters

Drain/spin and leak problems can quickly lead to bigger issues: soaked loads, odor, vibration, and extra strain on the motor and suspension. Catching the cause early (hose, lid lock, or drive components) keeps repairs simpler and protects the tub and basket.

In a Whirlpool washer like model WTW4105SW0, the parts that fail most often are the ones that move the load, control draining and spinning, and confirm the lid is safely locked. When these parts wear out, you typically see no-spin/no-drain symptoms, unusual noise, or the washer stopping mid-cycle.

Most common failures (and what you notice)

• Lid lock problems: washer will not start, stops, or will not spin; often tied to a failed lid lock.
• Drain and hose issues: slow drain, standing water, or leaks; commonly related to hoses or clamps.
• Drive system wear: squealing, grinding, burning rubber smell, weak agitation, or no spin.
• Shifting/drive control issues: washer agitates but will not spin (or vice versa).
• Control/knob interface wear: cycle selection issues or inconsistent starts.

Parts on this model that commonly solve those symptoms

These are examples of parts available for WTW4105SW0 that match frequent failure points:

Symptom	Likely system	Example part for this model
Won’t lock or won’t spin	Lid lock	Latch, lid lock assembly W11513248
Won’t shift between agitate and spin	Shifter/actuation	Actuator, shift W11481722
Loud noise under washer, slipping	Drive/pulley	Whirlpool washer drive pulley W10721967
Leaks at hose connection	Hose/clamp	Clamp WP285655

Quick checks before replacing parts

• Confirm the load is balanced and the washer is level on the floor.
• Check for coins, socks, or debris between the basket and tub.
• Inspect fill and drain hoses for bulges, cracks, or loose connections.
• If the washer will not spin, listen for a lid lock click when starting.
• If you see an error code, match it to the closest Whirlpool washer family guide to narrow the failure.

Why it matters

Most washer breakdowns are “single-point” failures: one worn mechanical part (pulley, actuator) or one safety/control part (lid lock) can stop the entire cycle. Identifying the symptom first helps you avoid replacing good parts and gets your Whirlpool washer running sooner.

Some Whirlpool washer parts are interchangeable across multiple models, but we match parts by model number because small design changes can make a “similar” part fit poorly or fail early. For Whirlpool WTW4105SW0, use the parts listed for this exact model to ensure proper fit and performance.

What “interchangeable” really means for WTW4105SW0

Whirlpool often uses the same style of components across a washer platform (for example, lid lock, actuator, or drive parts). Even so, the correct part is the one that is listed for WTW4105SW0, because revisions can change:

• Electrical connectors and wiring length
• Mounting holes, tabs, and alignment features
• Calibration or shift timing (especially for drive and shift components)
• Material thickness and wear surfaces
• Included hardware (screws, clips, retainers)

When it is usually safe vs risky

Here is a practical way to think about it:

Part type	Interchange risk	Why
Cosmetic hardware (clips, some screws)	Low	Fit is mostly physical and non-electrical
Hoses and clamps	Medium	Length, diameter, and routing vary
Lid lock and actuator	High	Wiring, mounting, and control compatibility matter
Drive system parts (pulley, shield)	High	Alignment and belt/drive geometry affect spin and noise

Examples of model-matched parts for this washer

If you are troubleshooting a specific symptom, start with the exact replacement part listed for WTW4105SW0, such as:

• Actuator, shift W11481722 (common for no-agitate/no-spin or shifting issues)
• Latch, lid lock assembly W11513248 (common for won’t start or lid lock errors)
• Whirlpool washer drive pulley W10721967 (common for squealing, slipping, or weak spin)

Why it matters

Using the correct Whirlpool part for WTW4105SW0 prevents repeat failures, reduces noise and vibration, and avoids electrical mismatches that can cause new error codes or cycle problems.

If you are chasing an error code

Match the code to the washer style first, then confirm the part by model number. Our Whirlpool compact top load washer error codes guide is a good starting point.

For a Whirlpool washer like model WTW4105SW0, most repairs typically land in the $150 to $400 range (parts plus labor). Smaller fixes such as a lid lock or hose issue often cost less; major drive or electronic problems can push the total into the $400 to $700+ range.

What usually makes the price go up or down

Repair cost is mostly driven by the failed part, the time to access it, and whether the washer is also showing symptoms like not draining, not spinning, or not locking the lid.

Common cost drivers include:

• Service call/diagnostic fee (often applied toward the repair)
• Labor time (simple external parts vs. deep tear-down)
• Part cost (mechanical parts usually less than electronic assemblies)
• Multiple failures (for example, a drain issue plus a lid lock issue)
• Age/condition (rust, seized fasteners, or tub wear increases labor)

Typical repair scenarios for WTW4105SW0

These examples use real, model-relevant parts from this page to show how costs commonly break out.

Symptom	Likely area	Example part on this page	Typical total (parts + labor)
Won’t start or won’t lock	Lid lock system	Latch, lid lock assembly W11513248	$180 to $350
Won’t agitate or spin correctly	Drive system	Whirlpool washer drive pulley W10721967	$200 to $450
Won’t shift between agitate/spin	Shifter/actuator	Actuator, shift W11481722	$250 to $500
Leaks or won’t fill properly	Fill hoses/clamps	Washer water inlet hose, 2-pack 8212487RP	$120 to $250

When repair vs. replace makes sense

A practical rule we use: if the repair is under about half the cost of a comparable replacement washer, repairing is usually the better value, especially when the basket and tub are in good shape.

Why it matters

Getting the failure diagnosed correctly prevents repeat service calls. For example, a “won’t spin” complaint can be caused by a lid lock problem, a shifting problem, or a drive pulley issue, and each points to a different repair path and cost.

Helpful DIY troubleshooting before scheduling service

These quick checks can narrow the problem and reduce guesswork:

• Confirm the washer is getting power and the outlet is working.
• Make sure the lid closes fully and nothing is blocking the latch.
• Verify both water supply valves are fully open.
• Check that the drain hose is not kinked and the standpipe is not clogged.
• If the washer won’t drain or spin, review troubleshooting a top load washer that wont drain or spin video.
