Repair Guide or Tube Diagram for Bissell Proheat 2x 8920?

I have a Bissell Proheat 2x 8920 that initially would not spray to the floor. Then it no longer sprayed to the tools. I took it apart and cleaned lots of calcium type deposits from the heater. When I reassembled, the spray to the tools worked, but it still would not spray to the floor. So, I just took it apart again and cleaned every single tube and connection....well now, I am unsure how exactly it went back together.

Can someone...anyone please provide a service repair manual, a tubing diagram, or even a picture of their 8920 with cover removed so I can see where each piece goes??
