I've gone as far as taking the bottom off. Sounds like you took out the screws from the top side. Put them back, remove all the racks/rollers. Disconnect the plugs on the circuit board.

The spray rods might need to be cleaned, I found a bit of debris in mine. The pumps do need to be primed - if your leak is letting air in before the pump it would stop it from pumping, best not to run it long this way. If I recall I had to reset the control board to get the first bath temp control to work.
It should look like this:
