I got this second hand from my sister. I was told that it was fairly new. I've had it for a while in the house but just got my old washer out and hooked up. They said something about not doing big loads of laundry so I haven't been. Well I started a load of laundry before I left for work, about a half hour before I left. It was still agitating stuck at the 12ish minute mark after 9 hours! It smelled just a bit like burning electrical/plastic/rubber. I shut it off and waited until the next day. I turned it back on after advancing it to 9 minutes and watched it carefully. It ran fine. I finished that load and did an additional load since then. Tonight I tried to wash clothes and it stops when it gets to the spin cycle and won't pump the water out. It just hums or buzzes the hole time and does not jump to the next cycle. I'm a automotive mechanic but I've replaced a motor on a washer before. Its not outside my ability to work on it. So, I'm begging for ideas here. I believe the model number is W10140921 B. That is the only number I could find. Help please.
