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?

That does seem pretty obligatory. We have the same thing on our irrigation (don’t want irrigation water backflowing in to the drinking water, and also it’s required).
We are at the top of a hill and everything flows down from us to the entire neighborhood, so that is another good check on the issue.
