The way I over road the issue with water not pumping was to first apply what many have recommended. Clean the filter trap below. etc.
I attach my small shop vac with a slightly larger diameter to the drain port. I removed the rubber elbow connector to the drain hose. When the unit goes into the drain mode after it is turned off and only the red door lock is lit while the low humming sound of the pump is present.
I turned on the shop vac for a few seconds where some water will suck out and after a short period the pump will sense a dry run and turn off while unlocking the door.
Then, I passed a degreaser into the soap tray and rain the clean unit cycle where the dial points down.
This allowed it to cycle with no clothing and turn off. Even if F06 or F09 is the 2nd error code do the same. Vacuum the drain port to help remove the water.
I will add a split hose where I close the open end. When I need to suck the water at the end, I can put it in the open end without having to disconnect anything.
At least, this will work until the real issue is repaired. I start with the simple issue. If you can remove the water and it operated like normal, then it may not be a board or an electric issue. It might not be a pressure sensor issue if it can sense an empty tub. I might be a hose configuration issue or a damaged tube or perhaps the air tube. but something less costly.
