When a full cycle is first started there is no "click" and the tub no longer turns as the machine does its "little bit of water here and a little bit there" routine before commencing the wash cycle. The agitator is working. Same when it come to rinse and spin or drain and spin: the water will drain, the agitator will spin but the tub is still locked so the agitator rolls all the clothes into balls against the wall of the stationary tub. I have changed the drain motor/brake solenoid unit for one known to work with no change to the above.
Can anyone point me in the right direction for finding why brake is not disengaging?
