I watched the online video showing how to remove the cabinet and then was able to easily replace the water pump in just a couple of minutes.
Replacing the agitator cam kit was somewhat complicated by the fact that the original bolt head was very rusted due to the inner cap o-ring leaking. I cleaned as much rust away from the bolt head and used a six-point socket to remove the bolt. Following that, replacing the agitator cam kit was a straightforward process. I did replace the inner cap and o-ring.
The door switch was very easy to replace by following the online video.
At a minimum, I do suggest watching the video(s), made available by Appliance Parts Pros, showing how to disassemble the machine before starting the repair. This can save a lot of time and frustration.
