...VMW: Vertical Modular Washer-new design introduced by Whirlpool in 2010: PSC motor reverses back and forth for agitation,timer motor driven "mod shifter"couples basket to drive pulley for spin,agitator driven through planetary reduction gearbox.Made in agitator,agipeller and impeller/washplate versions.In my experience,recovering discarded VMWs,trouble areas include main seal/ruined upper bearing,bad pc boards,bad lid switch/lid lock, and once a bad mod shifter. Agitator shaft broken loose at weld from planet gear carrier inside transmission has been reported too.
