Spin cycle unpredictably failed to initiate

This job was extremely simple. First I unplugged the washer and disconnected the water supply lines. Then I removed the top of the washer control panel (2 hex screws) and then the back side of the control panel (3 Phillips screws). The front of the control panel then pivots forward towards the washer lid, giving easy access to the timer assembly. Unfastened old timer assembly (2 hex screws). Unscrewed timer knob on the front of the control panel, and pried off the plastic disc beneath that knob, thus freeing the timer knob post so I could pull it through the front panel for removal. Last I simply unplugged the jumble of wires that go into the timer, since they all conveniently come together in one plug. Reversed all of these steps to install the new timer assembly. Total time: about 45 min.
