Where to look for crud in this 80's Hotpoint dishwasher?

Photo of the underside of an upside down 80's vintage dishwasher, pump
removed. Everything seems to be running fine but it's been leaving crud and deposits on the dishes. Apparently a common culprit is debris caught somewhere but it's not obvious to me where to look on this model. There's a finned filter on the inside of the machine at the center of the bottom (the hole on the left of the photo is on the outgoing side of that filter) but it would only trap fairly large
objects. There's a plate with holes at the back of the intake side of this pump, visible in the photo. I didn't find much there.

Where else could debris be lurking?

Thanks for all input.

Is there a model number lurking inside that machine

Could be a grinder issue.
Did you remove the drain line and check it for obstructions.
Also make sure the drain line is tied up high so that water can not drain back into the machine.

As it turns out there was crud in various locations - on both sides of the flap behind the bottom of the door, inside the float cup, the pass-through for the vent, under the soap dispenser cup. Merely using one of these bottles of dishwasher cleaner was never going to do the job - had to do a lot of disassembly to get to it. Did a bunch of other TLC while I was at it.

Works great now.
