1) Cleaned all sprayer arms. Many of the outlet holes were clogged with small debris (mostly small bits of food and a Jolly Rancher candy wrapper).
2) Removed circulation pump to clean impeller assembly. It was really clogged with stuff (more candy wrapper, shards of glass, a small metal screw). Luckily impeller fins were intact.
3) Re-assembled. Watch for some sharp edges when re-connecting sump well.
4) Performed three or so test wash cycles pulled out from under counter to make sure I had no leaks. One small leak around drain pump connection to sump well when discharging. I did not have a high loop in the drain line going to under sink. Put the high loop in and re-tightened drain pump and so far so good.
5) Going to still wash a few more cycles with dishes while pulled out to confirm no leaks.
