Product review (1 stars): Would not recommend this POC to anyone
We added the Whirlpool washer/dryer package when we bought our house in September 2011 and by the time December 2012 rolled around the 4950xw stopped working.  Just before it stopped working, in the middle of a wash cycle, it started making odd sounds like grinding gears and slipping belts.  Luckily the builder and Whirlpool gave us a two year warranty so we emailed and we waited.  Whirlpool contacted us first and instructed us to unplug the machine for about two minutes because it might just need to be reset and the operator also asked if we tried other troubleshooting.  It was only after being on the phone with Whirlpool for fifteen minutes that the operator made the service request when the blinking lid locked light did not reset.  A&E Factory Service contacted us and we again had to explain the problem and what was done to try to troubleshoot the problem.  The service technician came and upon examination of the washer he concluded the nut at the bottom of the machine that keeps the pulley in place was loose.  He also noted the belt had rubbed on the plastic shield which was the source of the slipping belt sounds.  So, he replaced the belt, tightened the nut and says he applied some Loctite on the nut to prevent this from happening again.

Long story a little shorter, the sounds are back, the loads are taking longer and we're thinking about hauling this POC to the local dump and buy a new washer with an agitator and it won't be a Whirlpool!  While we decide we're going to email Whirlpool and set-up a service call because we have until Sep 2013 before the extended warranty expires.  From our experience with this machine if the loads are taking a long time to finish and it starts making grinding or squealing noises you might want to check the nut underneath the washing machine for tightness.  The pulley it keeps in place has gears that mesh with the gearcase so if the nut is loose the pulley isn't meshing with gearcase and the washer will not work correctly.  When it was working correctly for the past two months it seemed like a decent washer but now that we're having the same problem again, we're ready to dump it for something else.  Hope this review is helpful.
