Detergent door problems

Greetings All and Happy New Year!
I’m looking for a manual or some detailed instruction on troubleshooting the detergent door for a Kenmore Model 665.15529000. I have had the inner door off and found an exceptional amount of dried detergent around the bottom of the assembly. Not sure if this is the main culprit. I cleaned it up and moved some parts and such, reattached the inner door and spun the dial a few times. Detergent door appeared to work properly. Put the dishwasher through its cycles in an actual wash and the detergent door didn’t open. Springs are all good - detergent door hinge and on the actuator inside the inner door.
Any suggestions?
Thanks for any and all help.
