0E error code on the LG web site pointed to a problem with the draining system. Took the dishwasher outside and tried to flush and snake the drain line. A small rubber disk came out of the dishwasher. Using the drawings and parts list on the AppliancePartsPros web site, I was able to find that the part was part of the drain check valve. The video on the repair was very close to the actual repair. Ordered the check valve and a dishrack roller I was missing, and it's now fixed. AppliancePartsPros has been super useful in my appliance repairs and the prices are the lowest I could find.
