Whenever you are shopping for a compact LG washer and dryer, you need to make sure you understand there are differences between combination units and stackable units. Combo units are a single appliance which allows you to perform both your washing and drying functions in the same unit. Stackable units, on the other hand, are two separate mini-appliances combined into a stacked design to help save on space. The washing is performed in the bottom unit, while drying is completed in the top unit. Stackables can also be separated from one another and placed side-by-side.
Another difference between combination and stackable LG washer and dryer appliances is in how you do laundry. Stackable units allow you to wash one load of clothes at a time, while another is able to be dried simultaneously. With a combo model, you can only do one load at a time, as both washing and drying cycles have to complete before you are able to start another load. Because of this variation in cycle times, many people change their laundry habits and do a load once every few days, rather than attempting to do all of their laundry in a single day. However, you do gain the advantage of being able to put your load in the combo appliance, select your cycles, and then be free to do anything else, because you do not have to wait around for the washing cycle to complete before being able to transfer your clothes into the dryer. Further, a combo unit is ideal for anyone who frequently forgets and leaves wet clothes in their washer.
