The F09 error is a water pump problem, either clogged pump, or pump malfunctioning, Check for something clogging the water pump. To do that, open the lower access panel by unscrewing the 3 torx screws at the very bottom of that panel, then you will see the plastic water pump in the middle front, just unscrew the handle, get a few dry towels as some water will come out.
We have also been getting the F09 code but only on Delicate cycle, not on Normal cycle... It does it 5 minutes before the end of the cycle and will only move forward if we turn it off and then back on. It then runs the remaining 5 minutes.
