LG WT8400CBPRK1 Washer and Dryer Pair Review

The pair is one purchase made of two machines, plus the parts that let you hook them up.

The capacity figures belong to different machines. The listed capacity is 7.3 cubic feet; the washer is 5.5 cu. ft. Both are large, and 5.5 cu. ft. without an agitator is a genuinely big wash drum, but do not expect a 7.3 cu. ft. washer.

The finish is matte black.

The washer does the heavy lifting, and the dryer backs it up with drying that stops when the clothes are dry.

Washing performance

The impeller and wash-plate design with TurboWash shortens cycles and rinses thoroughly. The washer is built for large household loads, bedding and heavy fabrics, and its washing performance sits at the top of the scale.

Capacity in practice

The drum holds 5.5 cu. ft. Because there is no agitator, the usable volume is close to the stated figure.

Quiet running

LoDecibel construction and the inverter direct-drive motor keep spin and wash noise low. Vibration is well controlled, which matters if the laundry sits near a bedroom or living space.

Drying that stops when the clothes are dry

Sensor Dry measures moisture and adjusts the time. The dryer also includes a steam function that refreshes garments, reduces wrinkles and eliminates odors. The pair is ENERGY STAR certified.

Smart features that earn their place

SmartThinQ Wi-Fi gives cycle notifications, remote start, energy monitoring, Tub Clean coaching and Smart Diagnosis. Smart Pairing passes the wash cycle to the dryer so the dry settings match the load.

Build and warranty

The drum is stainless steel. The warranty runs one year on parts and labor, three years on the drum, and ten years limited on the inverter direct-drive motor.

Everyday ergonomics

EasyUnload angles the drum front, and the SlamProof glass lid closes softly.

The compromises are real but narrow, and most of them come down to how the washer treats fabric.

No dedicated delicate cycle

The washer's program list covers Normal, AI Wash, Bedding, Quick Wash, Heavy Duty, Deep Wash, Waterproof and a downloadable slot. There is no Delicates program.

Gentleness is the trade-off

Washing and water efficiency sit at the top of the scale, but fabric gentleness rates only fair. Heavy-duty cleaning and delicate care pull in opposite directions here.

The detergent dispenser holds water

The four-tray dispenser can retain liquid after a cycle. Rinse the tray, wipe the cavity, leave the drawer slightly open between loads, and use the right amount of high-efficiency detergent so thick residue does not block the siphon.

Small loads are not its strength

A couple of items in a 5.5 cu. ft. drum get less mechanical action than a full load.

Cycle flexibility is limited

Some option combinations are tied together. Adding an extra rinse, for example, can force a deep fill.

The finish and the lid

The tinted glass lid is dark enough that you cannot easily watch the wash. The lid is also sloped, so folded laundry cannot be stacked on top of the machine.

Installation is not plug-and-play

The vented dryer needs a 240V/30A circuit and exterior venting. The pair is heavy and needs clearance around it.

These are the figures that decide whether the pair fits your laundry room and your loads.

The pair comes in matte black, weighs about 249 lb combined as shipped, includes a 12-month CPS protection plan, and works with smart home assistants. For fit, note that the washer is 28⅜ in deep.

The pair fits households whose laundry is dominated by volume: bedding, towels and heavy fabrics that fill a big drum.

It is a good fit for families and large households with those loads, for anyone replacing a front-loader who wants a top-load drum they can leave open to air out, for buyers who want quiet operation near living space, and for households that want a big washer and a vented dryer with steam and sensor drying.
