Whirlpool WTW5105HC3 washer Parts

Whirlpool washer parts are interchangeable only when the replacement part is listed as compatible with your exact model, WTW5105HC3. Even within Whirlpool, similar-looking parts can differ in mounting, wiring, or calibration; we match by model number and part ID, not by appearance.

What “interchangeable” means for WTW5105HC3

A part is interchangeable when it fits, connects, and performs correctly on the same washer design. For WTW5105HC3, that means using parts that cross-reference to this model’s parts list.

Common examples where exact matching matters:

• Drive system components such as the washer drive belt WPW10006384 and Whirlpool washer drive pulley W10721967
• Safety interlock parts (lid lock and lid strike) that must align and switch correctly
• Drain components (pump and drain hose) that must match ports and flow rate

How we confirm the right replacement part

Use the model number plus the part ID to prevent wrong-part returns and repeat failures.

• Match the model number exactly: WTW5105HC3
• Verify the part ID on the listing matches the failed component or approved substitute
• For electrical parts (actuator, capacitor, control board), match connectors and revisions
• Diagnose the symptom first (no spin, no drain, grinding noise) before ordering parts

Quick compatibility guide

Part type	Interchangeable across Whirlpool models?	What must match
Belts, pulleys	Sometimes	Belt profile/length, pulley size, mounting
Lid lock/strike	Sometimes	Alignment, switch style, harness connector
Drain pump/hose	Sometimes	Port size, mounting, electrical connector
Control boards	Rarely	Programming, harness layout, model-specific revisions

Why it matters

Using a “close enough” washer part can cause leaks, noise, poor wash performance, no-spin conditions, or recurring error codes. Matching by WTW5105HC3 keeps the repair reliable.

If you’re seeing a flashing code during a cycle, use a top-load Whirlpool code reference such as Whirlpool belt drive top load washer error codes to narrow the failure to the most likely system before replacing parts.

Yes. A 4.5 cu. ft. washer is considered large capacity in today’s market; it fits most family-sized loads and many bulky items. If you’re comparing to Whirlpool model WTW5105HC3 specifically, treat 4.5 cu. ft. as a capacity benchmark, not the exact spec for that model.

What “large capacity” means for everyday laundry

A 4.5 cu. ft. tub is designed to reduce the number of loads you run while still allowing clothes to move for proper cleaning.

• Handles most mixed loads for average to large households
• Works well for towels, jeans, and heavier fabrics
• Often fits a queen comforter; king comforters depend on loft and weight
• Helps prevent overstuffing, which improves rinse and spin results
• Leaves room for circulation when you load loosely (don’t pack items down)

Quick capacity guide (typical ranges)

Washer capacity	Common label	Best for
3.0 to 4.4 cu. ft.	Medium	Couples, smaller weekly loads
4.5 to 5.0 cu. ft.	Large	Families, towels, bedding
5.1 cu. ft. and up	Extra-large	Frequent bulky loads, big households

Why it matters

When a washer is overloaded, clothes can’t tumble or circulate correctly; that reduces cleaning performance and can increase strain on drive components such as the washer drive belt WPW10006384.

Tips to get the best results from a 4.5 cu. ft. washer

• Load loosely; keep space at the top of the basket
• Mix large and small items to help balance the load
• Use the Bulky/Bedding-type cycle when washing comforters
• Measure detergent carefully (HE detergent for HE washers)
• If a heavy load won’t drain or spin, follow troubleshooting a top load washer that wont drain or spin video

On a Whirlpool washer, an F1 E3-style code typically points to a control sensing or pressure (water-level) system problem, not a single “one-part” failure. On model WTW5105HC3, we start by checking the pressure hose for kinks/leaks and then evaluate the drain system and main control.

What to check first (fast, no parts)

• Unplug the washer for 2 minutes, then restore power and retry a cycle.
• Make sure the tub is empty of water; if it is full, run Drain/Spin.
• Check the standpipe and drain hose for a clog or a tight seal that can cause siphoning.
• Confirm the lid closes firmly and the strike is not loose or cracked.
• Listen for the drain pump: a steady hum with no draining often indicates a blockage.

Parts that commonly relate to this symptom on WTW5105HC3

If the basic checks do not help, these model-matched parts are common suspects depending on what the washer is doing (not filling correctly, overfilling, draining slowly, or stopping mid-cycle):

Symptom you see	Most likely area	Model-matched part to consider
Overfills, underfills, or fills then stops	Pressure sensing (air dome/hose)	Hose WP353244
Won’t drain, drains slowly, or stops with water in tub	Drain system	Pump assembly, drain W11399437
Won’t start or stops and won’t lock	Lid lock system	Lid lock-sol W11700916

Why it matters

The washer uses a pressure signal (through a small hose) plus control-board logic to decide when to fill, agitate, drain, and spin. If that signal is wrong (hose issue) or the washer cannot drain, the control can trigger an F1/E3 condition to prevent overflow, motor damage, or a no-spin-with-water situation.

When to move from checks to repair

• If the pressure hose is brittle, loose, kinked, or has water residue inside it, replacing the hose is a solid next step.
• If the tub will not empty and you hear the pump running, inspect for a clog; if clear, the drain pump is the next likely repair.
• If the washer will not lock consistently, address the lid strike and lid lock before chasing control issues.

The most common Whirlpool washer problems are failure to drain or spin, leaking, and loud operation. On the Whirlpool WTW5105HC3, these symptoms usually trace back to a lid lock issue, a drain pump restriction, or a worn drive system (belt or pulley).

Most common symptoms and what they usually mean

• Won’t drain / won’t spin: drain pump blockage or a failing pump, or the lid is not locking.
• Lid won’t lock / cycle won’t start: lid lock or lid strike not engaging.
• Loud banging or thumping: unbalanced load, washer not level, or a worn drive pulley/belt.
• Burning rubber smell or weak agitation: slipping belt or damaged pulley.
• Water on the floor: loose drain hose connection or a drain hose issue.

Quick checks we recommend first (no parts needed)

• Redistribute the load; run a Drain/Spin cycle with the tub empty.
• Confirm the washer sits solidly on the floor; adjust leveling legs until it does not rock.
• Check the drain hose for kinks and make sure the standpipe is not clogged.
• Listen during drain: a steady hum with little water movement points to a restriction or pump problem.
• If the lid does not click and lock, inspect the strike and lock alignment.

Common part fixes for these symptoms (WTW5105HC3)

Symptom	Most likely part area	Example model-matched part
Won’t drain / leaves water	Drain system	Pump assembly, drain W11399437
Won’t spin / lid won’t lock	Lid lock/strike	Lid lock-sol W11700916 or washer lid strike W11457841
Loud noise / poor agitation	Drive system	Washer drive belt WPW10006384 or Whirlpool washer drive pulley W10721967

Why it matters

Drain, spin, and lid-lock problems can look like a “dead” washer, but they are often straightforward fixes. Catching a slipping belt, a failing drain pump, or a misaligned lid strike early helps prevent repeat shutdowns and reduces wear on the drive motor.
