LG WM3370HWA/00 washer Parts

Most LG washing machines, including the LG WM3370HWA, typically last 10 to 15 years with normal household use. Consistent maintenance (cleaning, correct detergent use, and avoiding overloads) is what most often separates a 10-year washer from a 15-year washer.

What affects lifespan the most

• Load size and balance: frequent overloading or chronic out-of-balance loads increase wear on the tub support, shocks, and bearings.
• Drain health: coins, lint, and debris that strain the pump can shorten life.
• Water quality: hard water accelerates scale buildup on internal components.
• Door seal care: leaving moisture in the boot can lead to odor and deterioration.
• Fast fixes: addressing small leaks or slow drains early prevents bigger failures.

Maintenance checklist that adds years

Use the WM3370HWA owner's manual for the exact cleaning intervals and cycle recommendations for your washer.

• Run a monthly tub-clean routine (or the closest equivalent cycle).
• Wipe the door glass and door boot dry after laundry.
• Leave the door slightly open between loads to reduce moisture.
• Use HE detergent and measure carefully (too much causes residue).
• Check pockets to keep debris out of the drain system.

Common wear items and what they usually mean

Symptom	Common cause	Typical fix
Won’t drain or drains slowly	Pump obstruction or failing pump	Clean filter/hoses; replace pump if noisy or weak
Leaks at the door	Worn or torn door seal	Replace door boot
Won’t lock or start	Door lock/strike issue	Inspect latch alignment; replace lock/strike

If draining problems are frequent, the drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T is a common replacement part for this model.

Why it matters

A front-load washer’s big-ticket repairs (drain pump, door lock, suspension, tub components) often show up after years of vibration, moisture, and detergent residue. Preventive cleaning and avoiding overloads reduce stress on the drive system and help you reach the full 10 to 15 year lifespan.

The LG WM3370HWA washer has a 4.3 cu. ft. tub capacity, which LG classifies as an ultra-large capacity. For cycle options and loading guidance that help you get the best cleaning performance at that capacity, use the WM3370HWA owner's manual.

What 4.3 cu. ft. means for everyday loads

A 4.3 cu. ft. front-load washer like the WM3370HWA is designed to handle larger loads while still tumbling freely for proper wash action.

• Load items loosely; do not pack the drum tight
• Mix large and small items to help balance during spin
• Use HE detergent and measure carefully to reduce oversudsing
• Choose the right cycle for bulky items (bedding, towels) to improve rinse and spin
• If the washer vibrates or shows imbalance symptoms, reduce the load size and redistribute

Quick capacity guide (practical examples)

These examples help translate capacity into typical household loads.

Load type	Typical fit in 4.3 cu. ft.	Best practice
Everyday mixed laundry	Large load	Leave space at the top for tumbling
Towels	Medium to large	Avoid overloading to prevent poor spin
Bedding/blankets	One bulky item at a time	Use a bulky/bedding cycle when available

Why it matters

Capacity affects cleaning and spinning. When the drum is overfilled, clothes cannot tumble correctly, detergent may not rinse out well, and the washer can struggle to balance at high spin speeds.

WM3370HWA is an LG front-load washer model number. On Sears PartsDirect, it identifies the LG washer used to match the correct replacement parts and service information for your machine; confirm the full model and suffix on the rating label and in the WM3370HWA owner's manual.

How to confirm you have the right model

Use these quick checks so you order the correct LG washer parts (door lock, drain pump, inlet valve, etc.).

• Check the rating label (typically around the door opening or on the cabinet) for the full model and suffix.
• Match the label to the model format WM3370HWA/00 (suffix matters for parts compatibility).
• Compare your washer’s control panel layout and door style to the parts diagrams.
• Use the manual’s “product information” section to verify features and cycle names.
• If you are troubleshooting, note any error code before ordering parts.

Common parts customers replace on this LG washer

If your WM3370HWA has symptoms like not draining, not locking, or not filling, these model-matched parts are common starting points:

Symptom	Likely area	Example model-matched part
Won’t drain / drains slowly	Drain system	Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
Door won’t lock / won’t start	Door lock system	LG washer door lock EBF61315802
Won’t fill / fills slowly	Water inlet	LG washer single-solenoid water inlet valve 5220FR2006H

Why it matters

LG model numbers like WM3370HWA are the key to getting the right washer parts the first time. Even small suffix differences can change which door lock, water inlet valve, or drain pump motor fits and works correctly.

LG parts for the WM3370HWA washer often cost more because they are model-specific, built to tight fit and performance tolerances, and sold through a smaller compatible-parts pool than many universal components. Pricing also reflects distribution, inventory, and the complexity of electronic and sealed water-handling parts.

What typically drives the price up

• Model-specific engineering: Many LG washer parts are designed for a narrow set of models, which raises per-unit cost.
• Electronics and sensors: Boards, switches, and locks cost more than simple mechanical hardware.
• Water and leak-critical components: Valves, pumps, and hoses must seal reliably under vibration and heat.
• Supply chain and stocking: In-stock OEM parts carry warehousing and fulfillment costs.
• Labor-saving assemblies: Some repairs require replacing an entire assembly (not a small sub-piece).

Examples on the WM3370HWA parts list

These common replacements show how complexity affects price:

Part type	Example part on this model	Why it costs more
Drain component	Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T	Motorized, water-exposed, failure-prone wear item
Door safety	LG washer door lock EBF61315802	Safety interlock plus electronics and precise alignment
Fill system	LG washer single-solenoid water inlet valve 5220FR2006H	Solenoid valve, screens, sealing surfaces

How we recommend shopping smart (without guessing)

• Confirm the exact model number WM3370HWA before ordering.
• Use the part diagram and part number cross-check in the WM3370HWA owner’s manual.
• Compare “assembly vs. component” options; sometimes a smaller part solves the issue.
• Replace related wear items together when it prevents repeat labor (example: door boot and clamp).
• Fix the root cause first (clogs, oversudsing, unbalanced loads) so the new part lasts.

Why it matters

Using the correct OEM part helps your LG front-load washer fill, lock, drain, and spin safely. A cheaper, near-match part can cause leaks, error codes, repeat failures, or fit issues that cost more over time.

The most common problems we see with LG washers like model WM3370HWA are drainage and spin-related issues: slow or no draining from a clogged pump filter or failing drain pump, plus out-of-balance loads that trigger vibration and spin errors. For model-specific operating and care steps, use the WM3370HWA owner's manual.

Most common issues (and what they look like)

• Washer will not drain or drains slowly: water left in the tub, cycle stops before spin
• Excessive vibration or “won’t spin” complaints: load is bunched on one side, washer walks or bangs
• Musty odor or visible mildew (front-loaders): buildup around the door boot and detergent residue
• Filling problems: long fill times, no fill, or temperature issues tied to inlet valves
• Door won’t lock or won’t start: clicking but no cycle, or door lock errors

Quick checks we recommend first

1. Reduce and rebalance the load (bulky items and small loads are common causes of imbalance).
2. Clean the drain pump filter and check the drain hose for kinks or clogs.
3. Run a tub clean/maintenance cycle and wipe the door seal dry after use.
4. Confirm both water supply valves are fully open and inlet screens are not blocked.

Parts that commonly solve these problems on WM3370HWA

Symptom	Common fix area	Example part for this model
Won’t drain / loud humming during drain	Drain pump	Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
Won’t fill / fills slowly	Water inlet valve	LG washer single-solenoid water inlet valve 5220FR2006H
Door won’t lock / won’t start	Door lock system	LG washer door lock EBF61315802

Why it matters

Drain and balance problems can stop the cycle before high-speed spin, leaving clothes wet and increasing wear on the drive system. Regular filter cleaning, correct loading, and basic maintenance reduce repeat failures and help your LG front-load washer run quieter and longer.

For the LG WM3370HWA washer, replacing the rubber door seal (door boot) typically costs $120 to $350 total. The part commonly runs about $80 to $180, and professional labor is usually $120 to $200, depending on local rates and whether the clamp and related hardware also need replacement.

Typical cost breakdown

• Door boot (rubber seal/gasket): $80 to $180
• Labor (service call + installation): $120 to $200
• Optional related parts: $15 to $40 (clamps, strike, or small hardware)
• DIY supplies (optional): $5 to $15 (towels, mild cleaner)

Repair approach	What you pay for	Typical total cost
DIY replacement	Part (and possibly clamp)	$80 to $220
Professional replacement	Part + labor	$120 to $350

Parts that are commonly involved on this model

On WM3370HWA, the rubber seal is the door boot. If the seal is leaking or moldy, we also check the retaining clamp and door closing parts because a loose clamp or misaligned door can mimic a “bad seal.”

• LG washer door boot MDS47123602
• Clamp assembly ACA56078801
• LG washer door lock strike MFG63099101

What changes the price most

• Leak source: A torn boot costs more than a simple clamp reseat.
• Access and time: Front-load door boot installs can be time-consuming.
• Extra damage: Rusted clamps, soap buildup, or a warped door area can add time.
• Service minimums: Many shops charge a diagnostic/service call even if the job is quick.

Why it matters

A leaking door boot can cause water damage, odors, and repeated error conditions from moisture getting where it should not. Replacing the boot early often prevents secondary issues with the door lock and cabinet.

For model-specific diagrams and disassembly guidance, use the WM3370HWA manual.
