This was incredibly helpful, thank you so much. Turns out we experienced almost all of the above. At first we thought it was the heavy gunk and debris at the "coin filter", then the fairly clogged drain line. Finally after going back through the posts noting that the F02 code is a slow drain compared to the timer, we found a bra liner clogging the main drain hose (black flexible pipe under tub). Fair warning - even after draining the water at the filter, when I pulled out the clog the floodgates opened.
