    This Whirlpool GCQ9300E0 washing machine has a broken water level switch.
    Something fell from a shelf above the machine and snapped off the shaft. I
    disassembled the control but removed a screw that holds the cam follower
    before opening the control and was unable to easily figure out how the
    assembly goes back together.

    Here are some photos that should be helpful.

    These are the two parts that need to be reassembled back in the control.

    This photo shows the housing. The two parts shown outside the housing are
    what fit into the slot where the red arrow is pointing.

    And here are the possible orientations of the two parts:

    So the question is, which of the four above orientations is the correct way
    to reinstall the two parts? I tried a few combinations but rather than try
    every which way, I thought maybe someone already knew the answer. The couple
    of times I tried it, the water either didn't stop filling or stopped filling
    too soon.

    Thanks for your reply.

    Good point. I did order a new switch. I would never operate it the way it is
    now unless I was monitoring it every second. The point of my question was
    more academic than anything else. By the way, I think I have figured out the
    solution. The answer is that the screw I removed unnecessarily that holds
    the cam follower and the small plastic piece together is not actually there
    to hold it firmly in place. It's a height adjustment screw that can adjust
    the cam follower's travel. As you tighten the screw, it pulls the cam
    follower closer to the cam which in turn raises its elevation (like a
    see-saw) which puts more opposing force on the sensor switch. The screw head
    itself is hot glued to the outside of the housing to keep it locked in
    place. So if you ever have to inspect and/or disassemble the switch, don't
    mess with that screw! You can disassemble the housing just fine without
    touching that screw.

    Thanks for your reply.
