Product review (5 stars): My Washer Works Again!
Front Load LG Washer (WM2101H) would enter spin & rinse cycle then time out (IE error).  Purchased new drain pump motor off Amazon, arrived in a couple of days.  Installed new drain pump motor and now washer works fine (water actually drains, allowing the washer to complete the spin & rinse cycle).

Official reason for drain pump motor failure: unknown
Unofficial reason for drain pump motor failure: wife's long hair or dog hair on blanket!!!  :-P
