installing spring on dishwasher soap dispenser

trying to repair a soap dispenser that will not stay closed. Bought new spring and detergent latch but need help on how the spring gets loaded and how the mechanism works. Need schematics for both inside parts of the front dishwasher door.

model GE GSD640L-02WB

Here are your parts

If you click on the pictures of the parts (spring, lever etc.) used in the dispenser then a new page will open with info about that part. Often it includes a Q&A section with info on how to install the part.

We have already ordered the parts, detergent latch, shaft, and spring. The problem is putting it back together. How exactly does the spring fit on to the other 2 parts and how does it attach to the other side of the door. The picture on your website only helps for ordering parts. No manual available for reference or schematics available through Appliance Parts.com. Referred me to this forum for technical help
