Product review (2 stars): leaking after 21 months and very poorly though out software.
Did not buy from Amazon - but the WF42H5000AW - I've had for 21 months has now started leaking when water is being added to the unit.  Doesn't matter what part of the cycle, about 1/2 gal of water leaks out on each extended cycle that I run.  Its during the times that water is added - as I often pause the unit to soak and during that time no water seems to come out.
Also not happy with the software for the unit.  We always use cold water, but any rotation of the dial reverts to defaults.  It does have a my settings that stores everything - but it should use your last setting instead of defaults when a change is made.  Also very slow to power cycle - turn it off and it takes displays 'off' for ~5 seconds before you can turn back on.  Finally, really annoying door lock behavior.  Of course it shouldn't allow the door to open when turning or when a flood is possible, but when it would be 'safe' to allow it to open - it often does not.  To save time I start the wash and then continue to hunt for cloths -  but often get locked out.  I don't know if leaks and poor software design are the norm for this industry, but certainly it could be much better.
