LG WM3700HVA/00 washer Parts

The LG WM3700HVA washer has a 4.5 cu. ft. capacity. This is the tub size the washer is designed around; it helps you estimate how much laundry (like towels, jeans, or bedding) you can wash per load without overpacking.

How to use capacity the right way

Even with a 4.5 cu. ft. tub, performance depends on how you load and what you wash. For best results with WM3700HVA:

• Load items loosely; do not pack the drum tight
• Mix large and small items so the load balances during spin
• Wash bulky items (comforters, heavy blankets) by themselves
• Use HE (high-efficiency) detergent to reduce oversudsing
• Leave some space at the top so clothes can tumble and rinse properly

Quick reference: capacity vs. what you can wash

These are practical examples (not strict limits) to help you plan loads.

Load type	Typical fit in a 4.5 cu. ft. front-load washer	Tip
Everyday mixed laundry	Large load	Avoid stuffing; tumbling space matters
Towels	Large load	Balance with a few smaller items
Bedding	Usually 1 bulky item at a time	Use the correct cycle and do not overload

Why it matters

Overloading a front-load washer can lead to poor cleaning, extra vibration, longer cycle times, and out-of-balance spinning. Using the tub capacity as a guide helps protect parts like the door lock and suspension while keeping wash performance consistent.

For the LG WM3700HVA, LG does not state an “average lifespan” in the model’s documentation, so we can’t confirm a model-specific number. In general household use, many modern washers are often kept in service around 8–12 years, with maintenance and usage having the biggest impact.

What we can confirm for WM3700HVA

The model documentation focuses on care, troubleshooting, and warranty coverage rather than a predicted service life. For model-specific maintenance routines (Tub Clean, inlet filter cleaning, drain pump filter cleaning), use the WM3700HVA manual.

What most affects real-world lifespan

• Load habits: frequent oversized or heavy loads increase stress on the tub, shocks, and motor system
• Detergent use: using HE detergent and avoiding oversudsing helps prevent leaks and drain issues
• Moisture control: wiping the door glass and gasket area and letting the door stay ajar helps reduce odor and mold
• Water quality: hard water can contribute to scale and clogged inlet screens
• Early repairs: addressing leaks, loud vibration, or drain problems early can prevent secondary damage

Practical expectations (general guidance)

Usage pattern	Common service-life range (general)	Best habit to prioritize
Light use (few loads/week)	10–15 years	Keep it clean and dry between uses
Average family use	8–12 years	Monthly Tub Clean, avoid oversudsing
Heavy use (daily, bulky loads often)	6–10 years	Don’t overload, keep it level

Why it matters

A front-load washer like the LG WM3700HVA typically lasts longer when it stays clean, drains freely, and runs with low vibration. Those basics reduce wear on key components and help you avoid “small issue becomes a major repair.”

For LG washers, “HWA” is not a standardized feature code we can confirm for your exact model, LG WM3700HVA. In the WM3700 series, the owner’s manual shows the family format WM3700H*A, meaning the last letter varies by version or finish, so “HWA” may simply be a misread or a different model label.

What we can confirm for LG WM3700HVA

The LG documentation we have for this washer identifies the model family as WM3700H*A. That tells us the “H” and “3700” identify the series, and the final letter can change by variant.

• Your washer model: WM3700HVA
• Manual family format: WM3700H*A
• The manual does not define a specific meaning for “HWA” as a feature set

For model identification details, check the WM3700HVA owner’s manual.

Common reasons you might see “HWA”

In real-world use, we most often see “HWA” show up because of labeling or reading differences, not because it is a guaranteed LG code.

• The model tag was read incorrectly (for example, V mistaken for W)
• A retailer listing used a shorthand that does not match the full model number
• The washer is a different WM3700 variant than WM3700HVA
• The “/00” suffix (version code) was omitted or changed in a listing

Quick check: what to verify on the washer

What to check	Where to look	What to match
Model number	Rating label (typically door opening area)	WM3700HVA (and version like /00)
Serial number	Same label	Record it for service/parts
Finish/color	Visual confirmation	Helps avoid ordering cosmetic mismatches

Why it matters

Using the exact model number is the best way to match compatible parts and avoid fit issues, especially on door-related components.

• Door lock and latch alignment can be model-specific
• Control boards and wiring harnesses can vary by version
• Cosmetic parts can differ by finish

If you’re diagnosing a door that will not lock or unlock, a common related component is the LG washer door lock EBF61315802.
