What the LG WashCombo WM6998HBA Is
The WM6998HBA is an all in one machine: one drum that washes and then dries, in a single cabinet, with no duct to the outside. LG lists 5.0 cubic feet of capacity, an inverter heat pump for drying, a direct drive motor, 30 wash cycles, 7 dry cycles and a four tray dispenser.
The ventless part is the whole point. A conventional electric dryer pushes hot moist air out of the building through a duct, which is why dryers live on exterior walls. A heat pump machine instead recirculates air, condenses the moisture out of it, and drains the water away. That means it can be installed anywhere there is water, drainage and power, including interior closets, apartments and condos where a vent path does not exist and cannot be created.
Compared with the vented single unit approach of the LG WashTower WKEX200HBA, this is the machine for buildings that will never allow a duct.
The Electrical Question Has To Be Answered Before Buying
This listing states the voltage as 220 volts AC in one field, with a wattage figure written as 1.4E plus 3, which is scientific notation for 1400 watts. Those two numbers do not sit comfortably together, and the listing offers nothing else to resolve them.
The distinction matters enormously. Some ventless combination machines are designed to run from an ordinary 120 volt household outlet, which is a large part of their appeal in apartments. Others require a 240 volt dryer circuit like a conventional electric dryer. A buyer who assumes the wrong one either discovers on delivery day that the plug does not fit, or pays an electrician for a circuit that was never needed.
This review will not guess which applies here. The electrical requirement must be taken from LG’s own specification sheet for the WM6998HBA and confirmed against the receptacle in the laundry space, ideally by an electrician, before the machine is ordered. That is a five minute check that prevents a very expensive mistake.
Heat Pump Drying And The 2 Hour Claim
LG states wash and dry in 2 hours. No load size, no cycle and no test date is attached to that claim on this listing, which puts it well below the standard of evidence LG attaches to its TurboWash figures elsewhere. Treat it as a best case rather than a routine.
What can be said about heat pump drying generally is that it runs at lower temperatures than a conventional vented dryer. That is gentler on fabric and more energy efficient per pound of water removed, and it is also slower. Anyone moving from a vented dryer should expect longer drying times as a characteristic of the technology rather than a fault in the machine.
There is also a maintenance consequence that no listing mentions. Heat pump dryers have a condenser and a lint path that need cleaning regularly, and neglecting them is the most common reason performance drops off. The direct drive motor, by contrast, removes the belt from the drivetrain, which is a durability advantage.
The cycle count is unusually high at 30 wash programs and 7 dry programs. In practice most households use three or four settings, and a long list is worth less than a well chosen short one. What does matter on a combination machine is having a tub clean cycle, because a drum that stays warm and damp through a drying phase is a favorable environment for odor, and the four tray dispenser, which keeps detergent, softener and pre-wash separated rather than requiring manual dosing each cycle. Buyers who want a conventional washer with the same kind of dispenser arrangement should look at the LG WM3400CW.
Space And Door Clearance
The listing gives a genuinely useful figure that most do not: a maximum depth with the door open of 57.75 inches. On a front loading machine in a narrow laundry closet, that is the number that decides whether the door can open at all. The cabinet dimensions themselves are stated as 27 by 39 by 57 inches, with the fields labeling 27 as depth and 39 as width, which is almost certainly transposed for a 27 inch wide machine. Take the cabinet dimensions from LG’s specification sheet and use the 57.75 inch open door figure for planning clearance.
Highlights
- Ventless operation with no duct to the outside required.
- 5.0 cubic feet of mega capacity in a single wash and dry cabinet.
- Inverter heat pump drying, gentler on fabric than vented heat.
- Direct drive motor with no drive belt.
- Thirty wash cycles and seven dry cycles with a four tray dispenser.
- Stainless steel drum and touch controls.
- Published maximum depth with the door open of 57.75 inches.
Things To Consider
The voltage question above is the first thing to resolve, and nothing else should be decided until it is.
All in one machines dry more slowly than dedicated dryers, and a full 5.0 cubic foot wash load usually cannot be dried in one go because clothes need air space to tumble in. In practice that often means splitting a load for drying, which erodes some of the convenience.
The listing data is patchy. The included components field is prefixed with the word POSSIBLE, which is a scraping artifact rather than a statement about what is in the carton. Wattage and voltage both appear in scientific notation. No efficiency figure, no spin speed and no noise level is published.
Finally, a single machine cannot wash one load while drying another. Households doing several loads a day will get through laundry faster with a separate pair, for example a large front loader such as the GE GFW550SSNWW alongside a dedicated dryer, and the washers category and the dryers category cover those options. Buyers set on a combination unit should also compare the alternatives in the all in one washers and dryers category.
Who Should Buy It, And Who Should Not
It suits an apartment, a condo or an interior laundry closet where venting is impossible, where floor space allows only one machine, and where the household is small enough that slower drying is not a problem.
It is the wrong purchase for a large family doing back to back loads, for anyone who needs clothes dried quickly, and for anyone who has not confirmed the electrical supply the machine actually requires.
