Is this washer, WM4000HWA, able to be installed on a WDP3W pedestal?

Asked by: Mhuerta
Model WM4000HWA can be used with pedestal WDP3W. WDP4* replaced the WDP3* pedestal but they are both designed for compatibility with 27" LG Front Load Washers and Dryers. The only difference between them will be the mounting bracket installation. The WDP4* uses the t-clip installation method. ^Daphane

I just purchased the LG 4000 model and would like to know if I can wash my bedding blankets or the throw rugs in the bathroom

Asked by: Liz 228
Model WM4000HWA has a Bedding Cycle. This cycle is suitable for washing blankets or bulky items which have difficulty absorbing water, such as pillows, blankets, comforters, sheets or pet bedding. Do not use this cycle to wash a mixed load of bedding and non-bedding items. Do not mix large/bulky items with smaller articles of clothing. Do not wash excessively large items. If large/bulky items do not fit easily into the tub, there may not be enough room for them to move during washing. ^Daphane

Can you customize wash loads and settings to user preference? For example, can I use a Heavy Duty Cycle with any temperature that I wish? Or, does AI Tech not allow for a user to make custom selections? 

Asked by: JonD41
The wash cycles for the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity Smart Wi-Fi Enabled Front Load Washer with TurboWash™ 360° and Built-In Intelligence, Model # WM4000HWA are designed for specific types of wash loads. Each cycle has default settings that are selected automatically, but you can also customize these settings using the cycle modifier buttons. You can press the button for the desired modifier repeatedly until the indicator light for the desired setting is lit. The LED next to the setting lights up when the setting is selected. To protect your garments, not every wash temperature, spin speed, soil level, or option is available with every cycle. A chime will sound twice and the LED will not light if the desired setting is not allowed for the selected cycle. The AI DD provides the appropriate drum rotation actions after load sensing is completed and the AI DD Indicator lights up when the Normal cycle is selected and operated, except for when the Heavy soil level is selected...^Ivan

Why is there no drum light? More to the point, why do all the pictures on your website clearly show a light when there isn't one?

Asked by: Robbbb
The LG 4.5 cu. ft. Ultra Large Capacity Smart Wi-Fi Enabled Front Load Washer with TurboWash™ 360° and Built-In Intelligence, Model # WM4000HBA is not designed with a drum light. The lighting that you see in the images for the washer on our site showing the interior of the washer is either natural light coming into the drum or lighting that was used for the photoshoot for better visibility to show the interior...^Ivan

Can a king size comforter fit in this machine? Which dryer would you recommend if I purchase this washer?

Asked by: Farrah H
King size comforters come with varying types of filler material that make some bulkier than others. A capacity of 3.8 cubic feet has long been considered as being adequate enough to accommodate most, king-size comforters depending on how fluffy or bulky they are. The ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity Smart Wi-Fi Enabled Front Load Washer with TurboWash™ 360° and Built-In Intelligence, Model # WM4000HWA has a capacity of 4.5 cubic feet as indicated in its title, so it will accommodate most, if not all king size comforters. Our specifications on the washer's product detail page on our site list the ENERGY STAR® Qualified 7.4 cu. ft. Ultra Large Capacity Smart Wi-Fi Enabled Front Load Electric Dryer with TurboSteam™ and Built-In Intelligence, Model # DLEX4000W and its matching gas dryer, the ENERGY STAR® Qualified 7.4 cu. ft.
