Contractor installed this convoluted p-trap + elbow for the washer, and I'm not sure if it's up to code. Can you confirm and more importantly explain why or why not it's compliant?

Lol. No. Gonna get syphoned out ever time a toilet flushes past that or every time it pumps. No air gap/ directly connected prohibited by codes in most places. I mean it'll work until it doesn't. The proper way to do this is with a laundry tub dumped into a proper vented container/basin pump. Or run a drain over from that other pit and put a 48" stand pipe with a 2" trap.
