Pros & Cons
👍 Pros
- The 5.0 cu. ft. drum handles large family laundry loads — comforters, oversized towels, and high-volume loads — in fewer total cycles per week.
- The TrueBalance Anti-Vibration System delivers genuinely quieter operation at 1300 RPM spin, making second-floor installation a realistic option.
- LoadSense automatic water-level adjustment reduces per-load water consumption on partial loads compared to fixed-fill machines.
- The Direct Drive Motor carries a 10-year limited warranty, which is one of the strongest motor warranties available at this price tier and reduces long-term ownership risk.
- SmartDiagnosis enables remote troubleshooting via app or phone call, which can eliminate unnecessary service call fees for software-resolvable issues.
👎 Cons
- Front-load design requires consistent door gasket maintenance — neglecting it leads to mold and mildew buildup that produces odors and requires aggressive cleaning to resolve.
- At 207.5 lbs and 33"D x 27"W x 39"H, this washer requires a dedicated laundry space with proper floor reinforcement and ventilation — it cannot be treated as a portable or flexible-placement appliance.
- The 8 wash programs cover common scenarios but lack the granular cycle customization found on higher-end units — specialty fabric needs may not be fully addressed.
- The knob-based Dial-A-Cycle interface is straightforward but less intuitive for users accustomed to digital touchscreen controls when navigating between program options.
- Cold-fill-only operation (120V) means heating performance depends entirely on ColdWash technology rather than a dedicated heating element, which may not satisfy all performance expectations in extremely cold inlet water conditions.
Frequently Asked Questions
How loud is the WM3470CM during spin cycles, and can it be installed on a second floor?
LG specifically engineered the TrueBalance Anti-Vibration System to handle second-floor installation — it's one of the few features explicitly called out for above-ground-floor use. In practice, the 1300 RPM spin produces noticeably less vibration and sound transfer through flooring than older top-loaders, making it a legitimate option for laundry rooms above living spaces.
What does the SpeedWash cycle actually handle?
SpeedWash completes a cycle in 15 minutes, but it's designed for small, lightly soiled loads — think gym clothes worn once or a few shirts that need freshening. It is not a substitute for the Normal or Heavy Duty cycle for full loads or heavily soiled items. Using it appropriately for its intended load type is key to getting clean results.
How does SmartDiagnosis work, and does it require a subscription?
SmartDiagnosis transmits diagnostic data either through the LG ThinQ app over Wi-Fi or via an audio tone held up to a phone during a call with LG support. It does not require an ongoing subscription — it's a built-in feature that helps service technicians identify error codes and faults remotely before dispatching a repair visit, which can save a service call fee.
What is the LoadSense feature and does it save water?
LoadSense automatically detects the weight and volume of each load and adjusts water level and wash time accordingly. For households that regularly run partial loads, this translates to real water savings over time versus fixed-fill machines — the washer doesn't use full-load water for a half-load.
How demanding is tub maintenance on a front-load washer like this?
Front-load washers require consistent gasket and door seal maintenance to prevent mold and mildew buildup — this is a characteristic of the front-load form factor, not specific to this model. LG's TubClean cycle with the door-and-gasket drying step is designed to address this if run regularly (monthly is the standard recommendation). Leaving the door slightly ajar between cycles also significantly reduces moisture buildup.
