Product review (1 stars): Mold risk
I have model WL42T26DW1.  I have owned it 4 years.  For the most part it has worked fine, but my family started getting sick with asthma and allergy symptoms.  The cause was mold that we discovered after black gunky bits started getting on our clothes.  My husband disassembled the machine and the inner tub was completely covered in mold.
Let me explain how I clean before you jump to conclusions about user error.  I am OCD in my method.  We live in a clean, hypoallergenic house.  I do not use fabric softener.  I use the high efficiency detergent recommended by the user manual.  I use a vinegar rinse.  After each use I wipe down the tub, detergent dispenser and around the top of the tub.  Monthly I run the cleaning cycle as directed in the user manual.  I remove clothes immediately to put in the dryer (which we also have had to replace because of bad heating coils).  I leave the lid open between use.
The manual does not tell consumers to take the machine apart to clean.  I don't feel you should need to, but it is the only way to get in there.
I hope this is something that they address in other models, but do your research before purchasing and if you own a similar one beware of the hazard.
