Whirlpool Thin Twin washer not draining

Hi all, first post here. I have a Whirlpool Thin Twin and the washer portion isn’t working correctly. I’ve noticed two problems:

  1. Fills and starts normally, but completely stops halfway through the 12-minute cycle.
  2. As the washer sits there full of clothes and water, I’ll manually forward the dial to the "Rinse" position trying to get it to drain. It starts the Rinse cycle, but always stops directly between Rinse and Spin, picture below.

I tried pushing down the switch on the washer lid and it felt springy as usual, but now that I tried pushing it down all the way manually, it’s stuck in the down position. Note that I tried this -after- noticing both of the above, though it may still be the switch.

I’ve fixed many things before but never a washing machine, so I’d appreciate any help.
