LG WM3670HRA/00 washer Parts

Most LG front-load washers, including the LG WM3670HRA, typically last 10 to 15 years with normal household use and basic maintenance. This model uses an inverter direct-drive motor designed to reduce noise and vibration and support long service life (see the WM3670HRA manual).

What affects lifespan the most

• Load size and frequency: daily heavy loads wear bearings, shocks, and the drain system faster.
• Installation and leveling: an unlevel washer increases vibration and stress on the tub and suspension.
• Detergent choice: using HE detergent and the right amount helps prevent residue buildup.
• Moisture control: leaving the door slightly ajar helps reduce odor and mildew.
• Drain system care: keeping the drain pump filter area clean helps prevent slow draining.

Simple maintenance that helps WM3670HRA last longer

We recommend these habits because they directly reduce common wear items like the door boot, drain pump, and inlet valves:

• Run the Tub Clean cycle about monthly.
• Wipe the door seal/boot dry after the last load of the day.
• Leave the door slightly open using the magnetic door plunger feature.
• Check pockets for coins and small items that can jam the drain pump.
• Use the correct water hoses and replace worn hoses on schedule.

Quick expectations by age

Washer age	What’s typical	What to watch for
0–5 years	Mostly routine care	Installation vibration, detergent residue
5–10 years	Occasional repairs	Drain issues, door seal leaks, inlet valve problems
10–15 years	Higher repair frequency	Bearing noise, suspension wear, pump or valve replacement

Why it matters

A front-load washer’s biggest life-shorteners are excess vibration, moisture-related odor/mildew, and drain restrictions. Staying ahead of those issues helps the WM3670HRA clean better, run quieter, and avoid preventable part failures.

A UE error on our LG WM3670HRA washer usually means the load is unbalanced, so you often do not need a repairman. If the code keeps coming back after you redistribute the load and confirm the washer is level, service is recommended; see the WM3670HRA manual.

What to try first (no tools)

• Pause the cycle; wait for the drum to stop completely.
• Redistribute the load (separate tangled items; add 1-2 towels to help balance a small load).
• Avoid washing a single heavy item (blanket, rug) by itself.
• Run Rinse+Spin after reloading to see if it completes.
• Confirm the washer is not overloaded; the door should close easily without forcing.

Check installation basics that cause repeat UE

An out-of-level front-load washer can trigger repeated unbalance errors during high-speed spin.

• Rock the washer at the corners; it should not wobble.
• Make sure all four leveling feet are firmly on the floor.
• If the washer is on a pedestal or stacking kit, verify it is stable and level.

What you notice	Most likely cause	What we recommend
UE happens only with bulky loads	Load shifts during spin	Wash bulky items in smaller loads; use a cycle intended for bulky items
UE happens with most loads	Washer not level or load habits	Level the washer; load mixed-size items
UE persists even when empty or with a small balanced load	Mechanical issue (suspension or tub support)	Schedule service; a technician may need to inspect internal components

When it makes sense to call for service

Call for service if any of these are true:

• UE returns repeatedly after you level the washer and reload properly.
• The washer bangs loudly, walks, or vibrates excessively during spin.
• You see leaking, burning smell, or the washer will not complete a spin cycle.

Parts that can be involved (for persistent unbalance)

If a technician diagnoses a worn suspension component, one common related part for this model is the washer suspension spring MHY62964802.

Why it matters

Repeated unbalanced spinning can increase vibration and stress on the tub and suspension. Correct loading and leveling helps the WM3670HRA spin smoothly, reduces noise, and can prevent repeat shutdowns.

For an unbalanced load in our LG WM3670HRA washer, we pause the cycle, redistribute items evenly around the drum, and restart. If the drum is packed tight or you are washing one bulky item, removing or adding items usually stops the vibration and UE-type imbalance issues.

Quick fixes to try first

• Press Start/Pause, wait for the drum to stop, then rearrange the load.
• Remove a few items if the drum is overfilled or the door barely closes.
• Avoid washing a single small item; add a few similar items to balance the spin.
• Wash bulky items (blankets, comforters) by themselves.
• Check pockets and remove heavy items (coins, keys) that can throw off balance.

Installation checks that prevent repeat imbalance

Front-load washers like the WM3670HRA spin at very high speed; a slightly uneven floor can cause big vibration.

• Confirm all four leveling feet are firmly on the floor.
• Re-level the washer if it rocks when you push on the top corners.
• Tighten the locknuts after leveling.
• Make sure shipping bolts were removed during installation.

For model-specific leveling and installation steps, follow the WM3670HRA manual.

When it points to a worn suspension part

If the washer is level and loads are balanced but it still bangs or “walks” during spin, the suspension system may be weak.

Common symptoms include:

• Excessive tub movement when you push down on the drum by hand
• Loud thumping mainly during high-speed spin
• Frequent imbalance even with normal mixed loads

A common wear item is the shock absorber; see LG washer shock absorber ACV72909506 if you are diagnosing vibration related to suspension.

What to check based on the symptom

Symptom	Most likely cause	Best next step
UE/unbalanced only on bulky loads	Load distribution	Re-load, use Bulky/Large cycle, reduce load size
Washer rocks or vibrates every spin	Not level, floor flex	Level and tighten feet/locknuts
Constant banging even when level	Worn shocks/suspension	Inspect suspension components

Why it matters

Running unbalanced loads can increase noise and vibration, reduce spin performance, and put extra stress on the tub and suspension components over time.
