Bad agitator

After 2 years of using   Clothes weren’t getting clean. After looking down the glass in the door  I noticed the short little agitator wasn’t moving.  I took it apart and the plastics cogs were wore out on it.  So I ordered a new one which wasn’t that expensive and replaced it.  Easy fix. Torqued bolt to manufacturer specs and working again.  Until almost 5 months latter it happened again. This time removed it and noticed oil leaking out shaft seal. No wonder why my clothes were getting dirtier.  Never buy one of these again
