I have something caught in spin drum and I think it is disableing the pump in our 64850L. I would like to take pump off but cannot figure out how to take outer shields off to access pump. Access to a tech manual would be helpful. Also was wondering about electric motor brushes. I am using my older washer( 6200 ) now and have replaced brushes twice. Our newer model 64850L has a different configuration to take electric motor off. Do you have any solutions for me ?
