What People Are Saying

Rated 4 out of 5 by from Almost as nice as the Tromm I replaced. I only wish the washer tub had a light in it like my Tromm did....

Rated 5 out of 5 by from NEW Washer dryer I purchased this washer dryer combo, and so far I love it. I wish the add water feature added more water then what it does, but overall very happy thus far. It does take awhile to wash loads using the extra features, but I think its worth it. I am having trouble connecting the NFC to add extra cycles, but I'm sure ill get it. Time will tell if the reviews about not getting the clothes clean is true or not.

I need a longer drain hose or extension to make the current 5' drain approx 10'. Any recommended products to extend the drain hose?

Asked by: ScottJR
We appreciate your interest in this washing machine and its accessories. The end of the drain hose should not be less than 29” or more than 96” from the bottom of the washer cabinet. No extensions are available from, nor recommended by the manufacturer.

Stain remover was accidentally sprayed on the control panel and all of the lettering is coming off. You can wipe it off with your finger. So, by chance, do you have a control panel template? 

Asked by: Fritzy
I apologize, but no; there is no template available for the control panel of this washing machine. The closest thing we could recommend is the replacement of the control panel cover. Parts and accessories can be obtained through our parts distributor, MCM Electronics. Their contact number, for placing orders, is 800-824-9491. You can also use their website, at The part number for this item is: AGL74115120.

I don't see any water and when I open the door to check the laundry they don't seem like they are fully wet? They seem to work better when I put it on 'Water Plus" I always need to put it on water PLUS?

Asked by: leeann Now SF
We appreciate your interest in this washing machine. It is normal for the water level to come up from below the clothing. As this washer is designed to be water efficient, it is normal for the water to come no higher than the clothing. The wash motions will allow the water to come over the top of the clothing when the proper time comes.

What is the door panel on the bottom left of the washer 

Asked by: Moscow
That is the cover for the Drain Pump Filter on the LG 4.5 cu. ft. Ultra Large Capacity with Steam Technology, Model # WM3670HRA. The washing machine fails to drain if the drain pump filter is clogged, so you can open the Drain Pump Filter Cover to clean the Drain Pump Filter periodically to prevent clogging...^IFV

Is there a manual to clean the inner rubber piece inside the washer it has built up mildew from being used I guess ??

Asked by: LonnyKeitt
Any washer will do this UNLESS you leave the door cracked open so that the seal can dry out between uses.  We have never had any mold using this technique and I mean decades with locations from CA to NY.
