Dear Pros,

Product: Top-load GE Washer.
Problem: Washer doesn't engage spin cycle on it's own but water draining seems fine.

I find wet clothes at bottom of tub and there's an odour of slight burnt rubber in the air. So if I try to engage spin cycle manually by placing selector knob onto ''spin only'' selection and then ''turn ON'', it clicks, I hear the water pump working, but it doesn't engage spin (and we hear a BUZZing noise). At this point, if I manually (by hand) spin the barrel (in the right direction) to help the motor, it ''catches'' and starts the spinning and does it's job perfectly. Not always effective though. Sometimes I need to take out all the clothes (empty tub) and repeat that sequence to make it work.
I checked tube (linking tub to load sensor) for debris and seems very clean. Is it the sensor itself? Can it be the capacitor? I am hoping this is an easy fix.
Thank you for your time,
Andre
