LG WM3370HWA/01 washer Parts

Replacing the rubber door seal (door boot) on an LG front-load washer like model WM3370HWA typically costs $200 to $500 total (part plus labor). If you do it yourself, you usually pay $100 to $200 for the seal and reuse or replace the clamp as needed.

What you pay for (parts vs. labor)

Typical cost breakdown for a door boot replacement:

• Door boot (rubber seal): usually the main cost
• Clamp(s): the spring clamp may be reused, but many repairs go smoother with a new clamp
• Labor: most of the total cost if you hire service
• Service call/diagnostic fee: sometimes applied toward the repair
• Extra parts: only if there is related damage (hose, dispenser, door lock)

Scenario	Typical total cost	What’s included
DIY replacement	$100 to $200	Door boot, basic supplies
DIY with new clamp	$120 to $230	Door boot plus clamp
Professional service	$200 to $500	Part, labor, setup/testing

Parts that are commonly involved on WM3370HWA

For this model, these parts are often relevant when you’re fixing leaks at the door opening:

• LG washer door boot MDS47123602
• Clamp assembly ACA56078801

Why the price varies so much

A door seal job can be quick or time-consuming depending on what’s going on:

• Leak source: a torn boot vs. a loose clamp vs. oversudsing
• Access and disassembly: front panel and door area work takes time
• Condition of the old seal: stuck-on residue can slow removal
• Related issues: a misaligned door, worn strike, or door lock problems

Why it matters

A leaking or moldy door boot can lead to water damage, odors, and repeat leaks. Replacing the seal and confirming the door closes correctly helps the washer run reliably and keeps the interior drier between loads (we also recommend following the ventilation guidance in the WM3370HWA owner’s manual).

An LG washer like model WM3370HWA typically lasts 10 to 14 years with normal household use and basic maintenance. Keeping the tub clean, using the right detergent amount, and addressing drain or fill issues quickly helps you reach the upper end of that range; see the WM3370HWA owner's manual for care guidance.

Typical lifespan and what affects it

• Load size and frequency: daily heavy loads shorten life faster than moderate use
• Installation and leveling: an unlevel washer increases vibration and wear on suspension and bearings
• Water quality: hard water can increase scale buildup on internal components
• Detergent habits: too much HE detergent can cause oversudsing and stress the drain system
• Ventilation and cleaning: leaving the door ajar and cleaning the gasket reduces odor and mold

What “end of life” usually looks like

Symptom	Common cause	What we check first
Won’t drain or drains slowly	Clogged filter, failing pump	Drain path and pump operation
Won’t fill or fills slowly	Supply issue, inlet valve problem	Screens, hoses, valve function
Door won’t lock/unlock	Door lock or strike wear	Latch alignment and lock
Loud banging in spin	Suspension wear, unbalanced loads	Leveling and load distribution

Parts that often come up as washers age

If your WM3370HWA is otherwise in good shape, replacing a single wear item can extend service life.

• Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
• LG washer single-solenoid water inlet valve 5220FR2006H
• LG washer door lock EBF61315802
• LG washer door boot MDS47123602

Why it matters

Knowing the typical 10 to 14 year lifespan helps you decide whether to repair (common for a drain pump, inlet valve, or door lock) or plan for replacement if multiple major components are failing.

The most common issues we see with LG washers like model WM3370HWA are drain problems (slow or no drain) and fill problems (weak fill or inlet filter clogs). These show up as standing water, long cycle times, or water-related error messages; routine cleaning and hose checks prevent many failures (see the WM3370HWA owner's manual).

Most common symptoms and what they usually mean

• Washer won’t drain or drains slowly: drain hose kinked/clogged, pump filter blocked, or a failing drain pump
• Washer won’t fill or fills slowly: clogged inlet screens/filters, low water pressure, or a failing inlet valve
• Door won’t lock or cycle won’t start: door lock or strike alignment issue
• Musty odor or residue: tub needs cleaning, door kept closed between loads
• Out-of-balance shaking: load distribution, suspension wear, or leveling issue

Quick checks we recommend first (before replacing parts)

1. Unplug the washer and turn off water.
2. Confirm the drain hose isn’t pinched and is routed correctly.
3. Remove and clean inlet filters/screens; soak in white vinegar if scaled, then rinse.
4. Run a Tub Clean cycle as directed in the manual.
5. Leave the door slightly ajar between loads to help the interior dry.

Common part fixes for these problems

If the basic checks don’t solve it, these model-matched parts are common culprits:

Problem area	What fails most often	Model-matched part to consider
Not draining / slow drain	Drain pump motor	Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T
Slow fill / no fill	Water inlet valve	LG washer single-solenoid water inlet valve 5220FR2006H
Won’t start, door won’t lock	Door lock/strike	LG washer door lock EBF61315802 and LG washer door lock strike MFG63099101

Why it matters

Drain and fill problems can cause long cycle times, poor cleaning, leaks, and repeat error codes. Keeping inlet filters clean, using new hoses when installing, and maintaining the tub reduces strain on the pump, valves, and control system.
