"F09" is an Overflow Condition error. This is usually attributed to a malfunctioning pressure switch, loose or broken connector between the Pressure Switch, Drain Pump and Central Control Unit (CCU), or...a drain pump or drain line that has become clogged.
Since this problem occurs periodically during the wash cycle, I would check your drain pump filter for obstructions first. It could be that you have debris lodged in the pump causing it not to drain properly. To access the pump:
1. Unplug the washer.
2. Remove the lower kick panel under the door by removing the screws under the bottom edge. HINT: Placing a couple of blocks of wood under the front feet of the washer will make access much easier.
3. The drain pump is located under the wash tub in the center. HINT: If you own a shop vac, remove the drain line from the standpipe at the wall and pull a vacuum through the drain line. This will remove all residual water from the washer and make clean up later a lot less messy. Now, remove the cover on the drain pump and remove. Clean out the pump filter and check the pump impeller for obstructions.
If you do not own a shop vac, place a bunch of towels around the drain pump BEFORE you open it. There's about a gallon or so of water in the tub, drain line and pump.
Try this first, and let me know if this corrects your problem. If not, you may need to check the pressure switch and wiring. I hope this helps you.

F9 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.
