Kenmore Detergent Dispenser does not open

Hi All… I have a old Kenmore dishwasher and recently…after the cycle finishes, I noticed the Detergent dispenser cover does not open.

There is nothing blocking it.
I can push/pull the lever myself and the door will pop open.

I have the original parts list sheet, but not sure what this might be ? Lever ? Actuator ?

any help would be appreciated !

your model number is incomplete.
may be missing the first 3 digits. They designate who actually made the unit.

my bad…

Model 665.1586580
