i have a Gibson stack able unit did exact same thing .did everything but spin,and was a little louder than usual.i tore the whole washer apart.i bought a repair book teal reasonable thru repair ************.my problem was a bearing that is located down by the pulley that that turns washer .i have found that most stack able sets are more or less alike just have different parts .the front of book says repair kenmore tappan maytag on and on.on my bearing it says koyo which is manuf. has arrow one way says free the other side of arrow says lock which is what it does when it spins.Mind you this is on outside of transmission.But they (appliance places) dont sale says they will sale you whole transmission.which theres nothing wrong with except it dont spin.the other number on bearing says wc86205.iam going to go to a bearing place in my town(they all have to see it )there was a few on ******** for 29.00 hope this helps.remember it has to lock so it spins.i hope this helps it took me two weeks iam going tomorrow see if i can buy good luck
