Tub leaning too far forward causing water to spill while filling

Hello,
I’ve already replaced the three leveling springs (#3 on diagram).
I must be missing something that pulls the top of the tub to the rear or the bottom to the front.
Your help is greatly appreciated!

oops! It’s probably more than ten years old.

There should also be a counter-balance spring to offset the motor weight. It will connect to the rear of the chassis.
