About ready to turn in my man card. The left sink has the disposal, the right sink just a drain. The plumbing goes from left to right with a U under the right. Then off to the dishwasher. The backup looks like it's from the dishwasher from it's slimy chopped up contents but the dishwasher drained just fine.
I've poured some liquid plumber on the right sink to hit the U joint (which I don't think the clog is in) and tried plunging. Running the disposal only takes the water from the left to the right. After that both side equalize in level.
This is your typical dual well sink, disposal on the left, rinsing sing on the right. Plunging either side just moves water to the other side of the sink, but some water did spurt out the "dishwasher syphon/drain" or whatever that little pop up filter is on the sink next to the faucet.
