LG WM3370HVA/00 washer Parts

The LG WM3370HVA washer has a 4.3 cu. ft. capacity. That size is designed to handle everyday family loads efficiently while still fitting the standard 27-inch front-load footprint shown in the WM3370HVA owner's manual.

Quick specs for this model

Spec	Value
Capacity	4.3 cu. ft.
Washer type	Front-loading
Width	27 in.
Depth	29 3/4 in.
Height	38 11/16 in.

What 4.3 cu. ft. means in real use

A 4.3 cu. ft. LG front-load washer is built for medium-to-large loads. For best wash performance and spin balance, we recommend:

• Load items loosely; do not pack the drum tight
• Keep bulky items (comforters, blankets) to one at a time when possible
• Mix large and small items to reduce out-of-balance spinning
• Use HE detergent and measure carefully to prevent oversudsing
• Choose the correct cycle and soil level for the fabric type

Why it matters

Capacity affects cleaning, rinse performance, and vibration. Overloading a front-load washer can lead to poor turnover, longer cycle times, and more frequent unbalanced loads, even when the washer is level.

Drain and water-flow problems are the most common issues we see with LG washers like model WM3370HVA; they show up as slow or no draining, fill errors from clogged inlet screens, or cycles that stop mid-wash. Odor and mold around the door seal are also common on front-load designs.

Most common issues (and what they look like)

• Slow or no drain: standing water, long drain times, or a drain-related error; often tied to a clogged filter, kinked hose, or a failing pump.
• Fill problems: weak fill, fill errors, or long fill times; commonly caused by clogged inlet filters or low water pressure.
• Door won’t lock or unlock: cycle won’t start, or door stays locked; points to the lock or strike.
• Odor or mildew: musty smell from moisture trapped in the tub or door boot.
• Out-of-balance shaking: vibration during spin from load size, leveling, or suspension wear.

Quick checks we recommend first

1. Unplug the washer before any inspection.
2. Confirm the drain hose is not kinked and is routed correctly; many drain complaints are simple hose issues.
3. Clean the inlet screens if filling is weak (the manual notes clogged inlet filters can trigger a fill-related message).
4. Run the washer’s tub-clean routine and keep the door slightly ajar between loads to help the interior dry.

Parts that commonly solve these symptoms

Symptom	Likely area	Example part for WM3370HVA
Won’t drain / drains slowly	Drain pump	Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
Won’t fill / fills slowly	Water inlet valve or clogged screens	LG washer single-solenoid water inlet valve 5220FR2006H
Door won’t lock	Door lock system	LG washer door lock EBF61315802

Why it matters

Drain and fill issues can stop a cycle, leave water in the tub, and strain components. Odor and mold usually come from trapped moisture; improving drying habits and routine cleaning prevents repeat problems.

LG parts for the LG WM3370HVA washer often cost more because they are built to meet LG’s fit, performance, and safety standards for that exact machine, and many are sold as complete assemblies (not small sub-pieces). Using the correct part also helps prevent leaks, noise, and repeat repairs.

What drives the price up

• Model-specific engineering and testing: Parts are designed to match the WM3370HVA’s controls, sensors, and load handling.
• Assembly-level replacements: Items like a door lock or drain pump are commonly replaced as a unit, which raises cost.
• Materials and durability: Seals, housings, and electrical components are built for heat, vibration, and moisture.
• Supply chain and availability: In-stock OEM parts can cost more than generic alternatives.
• Warranty and compatibility expectations: OEM parts are made to fit correctly and operate within design tolerances.

OEM vs aftermarket: quick comparison

Option	Typical upfront cost	Typical outcome	Best for
OEM LG part	Higher	Best fit and reliability	Long-term repair value
Aftermarket part	Lower	Fit and lifespan vary	Short-term or non-critical fixes

Examples on this model where OEM fit matters

These WM3370HVA components are common “precision fit” items where correct mounting, connectors, and sealing are important:

• Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
• LG washer door lock EBF61315802
• LG washer door boot MDS47123602
• Washer water-level pressure switch 6601ER1006G

Why it matters

A cheaper part that does not match the original specs can cause issues like slow draining, door not locking, or leaks at the door boot. LG’s manual also emphasizes using authorized components and proper hose practices to reduce failures and water damage; we recommend following the WM3370HVA owner's manual.

For the LG WM3370HVA washer, replacing the rubber door seal (door boot/gasket) typically costs about $120 to $350 total. The part commonly runs $80 to $160, and professional labor is usually $150 to $250; DIY replacement mainly costs the part plus basic tools.

Typical cost breakdown

Item	Typical range	Notes
Rubber seal (door boot/gasket)	$80 to $160	Price varies by OEM vs compatible and supplier
Labor (service call + install)	$150 to $250	Front-load door boot replacement is labor-intensive
Total installed cost	$120 to $350	Lower end is DIY; higher end is pro service

What affects the price most

• OEM vs compatible part: OEM usually costs more but fits and seals more consistently.
• Clamp style and access: Some front-load designs require more disassembly time.
• Extra damage: A torn boot can hide issues like a loose clamp, debris, or door alignment problems.
• Local labor rates: Service pricing varies by region and minimum trip charges.
• Related parts: If the door is not latching correctly, the boot can get stressed and fail again.

When a “seal replacement” is not the only fix

If you see leaks at the front, also check these common contributors:

• Door not closing squarely (hinge or door alignment)
• Door not latching consistently (consider the LG washer door lock EBF61315802)
• Boot clamp popped off or stretched (the spring clamp is often involved)
• Excess suds pushing water past the boot (too much HE detergent)

Why it matters

A leaking door boot can let water reach the lower cabinet area, which increases the chance of corrosion, odor, and drain or electrical problems. Keeping the door slightly ajar between loads helps the interior dry and reduces mildew that can shorten gasket life (see the WM3370HVA owner's manual).

LG washing machines typically last 10 to 15 years. For your LG WM3370HVA, you can stay in that range by keeping water supply hoses and inlet filters in good shape, and by fixing drain, fill, or door-lock problems quickly using the WM3370HVA owner's manual.

Typical lifespan and what affects it

A washer’s service life is mostly driven by load size, cycle frequency, water quality, and routine maintenance.

• Light use (few loads/week): often closer to 15 years
• Average family use: commonly 10 to 15 years
• Heavy daily use: often closer to 10 years
• Hard water areas: can shorten life if inlet filters clog repeatedly
• Delayed repairs: small leaks or slow draining can turn into bigger failures

Maintenance that extends life (high impact)

The WM3370HVA manual calls out several items that directly protect components.

• Replace water inlet hoses every 5 years and check periodically for cracks or leaks
• Tighten hose connections correctly; do not overtighten
• Flush water lines into a bucket before connecting (helps prevent debris from entering)
• Clean the water inlet filters if water pressure is weak or an inlet filter is clogged
• Use only authorized components when replacing parts

Quick reference: what to do and how often

Item	What to do	Typical interval
Water inlet hoses	Inspect for leaks/cracks; replace	Inspect periodically; replace every 5 years
Inlet filters	Remove and clean (vinegar or descaler; rinse well)	As needed; more often with hard water
Drain performance	Address slow drain promptly	As soon as symptoms appear

When a repair is worth doing

If the washer is otherwise in good condition, replacing a common wear part can add years of reliable use.

• Won’t drain or drains slowly: consider the drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
• Won’t fill or fills slowly: check inlet screens first; then consider the LG washer single-solenoid water inlet valve 5220FR2006H
• Door won’t lock or cycle won’t start: consider the LG washer door lock EBF61315802

Why it matters

A front-load LG washer like the WM3370HVA depends on steady water flow, tight hose connections, and reliable draining. Keeping hoses and inlet filters maintained reduces leaks, fill errors, and pump strain, which are common reasons washers fail early.

Yes. The LG WM3370HVA front-load washer is designed to be stacked with a compatible LG dryer when you use an LG-approved stacking kit and follow the stacking and clearance requirements in the WM3370HVA owner's manual.

What “stackable” means (and what to avoid)

Stacking means the washer stays on the floor and the dryer is secured on top using a manufacturer-approved stacking kit.

• Use the correct LG stacking kit for your exact dryer model
• Never place the washer on top of a dryer
• Level the washer before stacking to reduce vibration and out-of-balance movement
• Do not improvise with generic brackets, screws, or straps
• Keep access to water shutoff valves, drain, and power after installation

Space planning for WM3370HVA (model-specific)

The WM3370HVA specifications list these dimensions:

Measurement	WM3370HVA specification
Width	27 in.
Depth	29 3/4 in.
Height	38 11/16 in.
Depth with door open	51 in.

Compatibility checklist before you buy a stacking kit

Use this quick check to avoid mismatches:

• Confirm the dryer model number on its rating label
• Verify the stacking kit is approved for that dryer and the WM3370HVA
• Confirm your closet or alcove clearances (rear hose space and door swing)
• Plan for vibration control (solid floor, washer leveled, feet locked)

Why it matters

A correct stacking kit and proper leveling prevent tipping risk, excessive vibration, and cabinet damage; they also help the inverter direct drive system run smoothly and quietly.

Yes. On the LG WM3370HVA washer, an OE error usually means the washer is not draining fast enough; you can often fix it yourself by cleaning the drain pump filter, straightening the drain hose, and clearing common clogs before replacing any parts. See the WM3370HVA owner's manual for model-specific safety steps.

What to try first (safe DIY checks)

• Unplug the washer before opening any access panels or handling wiring.
• Bail out standing water if needed, then clean the drain pump filter area.
• Check the drain hose for kinks, crushing, or a clogged standpipe at the wall.
• Make sure the drain hose is not pushed too far down the standpipe (it can siphon or restrict flow).
• Run a Drain/Spin cycle after clearing obstructions to confirm normal draining.

When a part is likely needed

If the filter and hose are clear but the washer still drains slowly, hums, or stops with OE, the drain pump can be failing.

Common OE-related parts for this model:

• Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
• Washer tub-to-pump hose 4738ER1002A

Quick symptom guide

What you notice	Most common cause	What we recommend
Water remains in tub, pump sounds weak	Partial clog in filter or hose	Clean filter, check hose routing
Loud buzzing/humming, little or no water movement	Drain pump impeller jammed or pump failing	Inspect for debris; replace pump if needed
Drains sometimes, fails other times	Intermittent blockage or pump wearing out	Recheck hose/standpipe; consider pump replacement

Why it matters

An OE condition leaves water in the tub, can prevent high-speed spin, and can lead to odors or residue. Restoring proper drain flow protects the pump, improves wash results, and helps the door seal area dry out between loads.
