Got a Kenmore washer model# 110.91521210
about 15 years old. Been running fine until today. While washing it started making a high pitch like sound(during rinse) then it just stopped. The motor kept humming but the machine seemed locked up. Turned it off and waited a while, tried it again. It agitated a few seconds(10-20 sec) then stopped again. It also has a hot electrical smell. I did get it to drain 3-4 inches of water out before it shut off again, so it will not work in any part of the cycle. I thought about the coupler
being bad, but would that keep it from draining?
I would appreciate your input.
