Product review (1 stars): Mold and Mildew
We were going to open up some space in a crowded washroom by replacing our functional, yet oldish side-by-side, top load washer and dryer.  This model was strongly recommended in several reviews of stackable front-loading sets, as well as the sales folks at Lowe's.  In not more than a month or so, the rubber gasket was covered in mold and mildew stains and the washer had that characteristic odor. We scrubbed and scrubbed with bleach and formulated mold/mildew remover.  It is impossible to get all off.

Now, we both are having problems with allergic reactions that bloom occassionally if we don't scrub this thing regularly to fight back the spore-producing mold.

It's a giant pain to constantly have to deal with this, not to mention the labor involved.  For something that was supposedly designed to be more energy efficient, I think it fails here as well.  The only tips I've gotten from sales and support folks is to weekly run empty, hot loads with a mold preventer.  I'm wondering if that 50+ hot loads were included in the efficiency rating...I doubt it.  Not to mention the additional expenditure to purchase this "specially formulated" mildew prevention detergent.

(We also experienced problems with the electrical panel of the dryer which went on the fritz after just 4 months - it was replaced.  The technician says "it's pretty common".  This did not reassure us.)

Do yourself a favor and stick with efficient top-loaders if you can.  From what I have been reading, this problem is not unique to this model in the front-loading washer field.  However, if you have to buy a front-loader, do a LOT of due diligence before making your significant purchase...

...And do yourself a favor. Skip this model or set completely.
