Description
What the LG WM4000HWA Is
The WM4000HWA is a 4.5 cubic foot front load washer built to a closet depth cabinet, aimed at households that want a large capacity machine in a laundry closet rather than a laundry room. LG rates it for loads up to 20 pounds, fits a stainless steel tub, and puts a tempered glass door on the front with chrome or rose gold trim depending on the finish.
It sits in the middle of LG’s front load range. Above it are the mega capacity machines such as the LG WM8900HBA at 5.2 cubic feet, and below it are the simpler models without connectivity or AI sensing. LG names its matching dryers as the DLEX4000W in electric and the DLGX4001W in gas, which matters if a stacked or side by side pair is the plan.
What TurboWash 360 Actually Claims
LG describes five jets spraying from multiple angles and states a complete clean in under 30 minutes. The footnote on that claim is important and LG publishes it: the figure is based on independent testing in the normal cycle with the TurboWash option selected, using a 10 pound load, dated June 2020.
A 10 pound load is well under half the machine’s 20 pound rating, and the TurboWash option has to be selected for the claim to apply. Both conditions belong with the number. A full load of towels on a heavy duty cycle will take considerably longer, and no reasonable reading of the specification suggests otherwise.
ColdWash is the companion technology, described as penetrating fabrics using different wash motions so that cold water gives warm water performance. LG presents this as a savings feature. No consumption figure is attached to it here, so it should be read as a design claim rather than a quantified saving.
The Allergy Certification Is Real
Among the marketing claims on this listing, the allergy figure is the one with independent backing. LG states that its AAFA certified washers with the Allergiene cycle remove over 95 percent of pet dander and dust, and attributes that to certification by the Asthma and Allergy Foundation of America. That is a third party certification rather than a manufacturer test, which puts it in a different category from the cycle time claim.
Worth noting: the cycle uses steam, which takes longer than a normal wash and uses more energy. It is a feature for households with a genuine allergy concern rather than an everyday setting.
Electrical And Installation
The specification sheet lists 120 volts. That is important on a washer, because a front load washer with an internal heater still runs from a standard household supply in North America, unlike an electric dryer. This is a plug in appliance, and the listing does not state an amperage or a plug type, so those should come from LG’s installation manual.
What the listing does not publish at all is the water connection requirement, the drain height, or the required clearances. Every front load washer needs hot and cold supply valves, a drain standpipe or laundry tub within the specified height range, and clearance behind the cabinet for the hoses. LG publishes those figures in the installation manual and they should be read before delivery. Shipping bolts also have to be removed before the first cycle, and running a front loader with them still fitted is one of the most common ways a new machine gets damaged.
Closet Depth
LG markets this as a closet depth machine, meaning the cabinet is shallower than a standard front loader so the door can still open in a tight laundry closet. That is a genuine advantage in an apartment or a hallway closet, and it is the main reason to choose this over a deeper machine of similar capacity such as the LG WM4200HWA. The saving is in depth only, so the height and width still need checking, and the door still needs room to swing clear in front of the cabinet.
Highlights
- 4.5 cubic feet of capacity, rated for loads up to 20 pounds.
- Closet depth cabinet for tight laundry closets.
- TurboWash 360 with five jets and a documented sub 30 minute test claim.
- AAFA certified Allergiene cycle with a stated reduction of over 95 percent of dander and dust.
- ColdWash technology and 12 listed wash cycles.
- NeveRust style stainless steel tub rather than porcelain or plastic.
- Energy Star certified, 120 volts, with ThinQ app connectivity and ThinQ Care alerts.
Things To Consider
Three specification fields on this listing are wrong and worth naming. Item weight is given as 20 pounds, which is the maximum load rating rather than the mass of the machine, and a 4.5 cubic foot front loader weighs an order of magnitude more than that. Maximum spin speed is given as 360 revolutions per minute, which is the 360 from TurboWash 360 rather than a spin speed, and 360 rpm would be unusably slow for a front loader. Access location is recorded as top load on a front load washer. None of these are product characteristics.
The buyer feedback base is very small, at 3.5 out of 5 across 4 ratings, which is not a usable sample. Connected features also depend on an app whose capabilities change over time, so they are a weak basis for choosing between machines.
Front loaders in general need a maintenance habit that top loaders do not: the door seal and the detergent drawer hold moisture, and a tub clean cycle needs running periodically. Anyone unwilling to do that should look at a top load machine such as the GE GTW500ASNWS, and anyone who wants washing and drying in one cabinet should compare the units in the all in one washers and dryers category.
Who Should Buy It, And Who Should Not
It suits a household with a laundry closet rather than a laundry room, a real need for large loads, and an interest in the fast cycle and allergy features. The closet depth cabinet and the stainless tub are practical rather than cosmetic advantages.
It is the wrong purchase for anyone who wants the simplest possible machine, anyone unwilling to maintain a front loader’s seal and drawer, and anyone whose electrical or plumbing situation has not been confirmed against LG’s installation manual first. The washers category covers the alternatives.
