What are the common problems with WM3670HVA?
Common problems we see on the LG WM3670HVA washer include not draining or draining slowly, water leaks, fill problems, detergent or softener not dispensing, and door lock or door-closing issues. Many of these symptoms trace back to a clogged filter, a hose restriction, or a failing pump, valve, or lock.
- Won’t drain / drains slowly: drain pump filter clogged, kinked drain hose, or a weak pump motor
- Leaking: loose hose clamp, damaged door boot area, or a cracked/loose drain hose connection
- Won’t fill / fills slowly: restricted inlet screens, low water pressure, or a failing inlet valve
- Detergent/softener not dispensing: dispenser drawer buildup, dispenser hose restriction
- Door won’t lock / won’t start: door lock or door plunger alignment issue
For model-specific operating checks and error-code guidance, we follow the steps in the WM3670HVA manual.
- Reset power: unplug for 2 minutes, then retry a Drain/Spin cycle.
- Check the drain path: confirm the standpipe is not blocked and the drain hose is not shoved too far down.
- Inspect for kinks and drips: look at the drain hose and all visible hose connections.
- Clean the pump filter area (if equipped): remove debris like coins, lint, and small socks.
- Confirm the door closes firmly: remove laundry caught at the gasket and check for obstructions.
If troubleshooting points to a failed component, these are common matches for the symptoms above:
| Symptom | Likely part to inspect first | What it does |
|---|---|---|
| Won’t drain / humming during drain | Drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T | Pumps water out of the tub |
| Won’t fill / slow fill | LG washer water inlet valve 5221ER1003A | Opens to let water into the washer |
| Door won’t lock / won’t start | LG washer door lock EBF61315802 | Confirms the door is locked for safe operation |
Drain, fill, and door-lock problems can stop the cycle mid-wash and can also lead to leaks or repeated error codes. Catching a clogged filter or a kinked hose early often prevents pump damage and reduces the chance of water on the floor.

What type of washing cycles does WM3670HVA have?
The LG WM3670HVA washer offers a mix of everyday, specialty, and maintenance cycles, including: Press, Delicates, Speed Wash, TubClean, Bulky/Large, Sanitary, Allergiene™, Heavy Duty, BrightWhites, Towels, and Download. For option details (temperature, spin speed, soil level), use the WM3670HVA manual.
- Press: Helps reduce wrinkles for items that crease easily.
- Delicates: Gentler wash action for lingerie and lightweight fabrics.
- Speed Wash: Short cycle for small, lightly soiled loads.
- TubClean: Cleans the washer tub; run with an empty drum.
- Bulky/Large: Bedding and larger items that need more room and water flow.
- Sanitary: Higher-temperature wash for deep cleaning.
- Allergiene™: Designed to reduce allergens on washable fabrics.
- Heavy Duty: Tough soils and durable fabrics.
- BrightWhites: Helps keep white loads looking brighter.
- Towels: Optimized for absorbent items.
- Download: Adds a downloadable cycle (requires the compatible LG feature/app setup).
| Laundry need | Best starting cycle | Helpful tip |
|---|---|---|
| Lightly soiled everyday items | Speed Wash | Keep loads small for best results |
| Bedding or bulky loads | Bulky/Large | Avoid overloading; items must tumble |
| Whites | BrightWhites | Use the recommended detergent amount |
| Towels | Towels | Don’t use too much fabric softener |
| Washer odor or buildup | TubClean | Run monthly or as needed |
Choosing the right cycle on WM3670HVA helps protect fabrics, improves cleaning performance, and can reduce issues like excess suds, poor draining, or musty odors.

Is the WM3670HVA energy efficient?
We can’t confirm a specific energy-efficiency rating for the LG WM3670HVA from the model-specific information available here (for example, an ENERGY STAR tier or kWh per year). For the most accurate, model-matched guidance on cycles and settings that affect energy use, use the WM3670HVA manual.
Even without a published rating in the model details, you can still reduce energy and water use on the WM3670HVA by choosing efficient cycles and avoiding re-washes.
- Wash full loads (without packing the drum tight)
- Use cold or warm water when the fabric allows; hot water drives most energy use
- Use HE detergent and measure carefully to prevent oversudsing and extra rinses
- Choose higher spin options when appropriate to shorten dryer time
- Keep the washer draining properly; slow draining can extend cycle time
| Setting or habit | What it affects | What to expect |
|---|---|---|
| Hot vs cold wash | Water-heating energy | Hot typically uses more energy |
| Extra rinse | Water use and run time | More water and longer cycles |
| Higher spin | Moisture left in clothes | Less dryer time afterward |
| Overloading | Cleaning performance | More re-washes, more total energy |
If the washer struggles to drain, it can pause, extend the cycle, or leave clothes wetter, which increases dryer time. If you’re troubleshooting draining, a common component to inspect or replace is the drain pump motor (4681EA2001T) - washer part by LG electronics 4681EA2001T.
Energy efficiency is not just the motor; it’s the combination of water temperature, cycle length, spin extraction, and whether the washer completes cycles normally without extra rinses or re-washing.
