Product review (3 stars): Genuine Product; Still Poorly Designed
This is a fix for the F01 error. There is also a DIY fix.

The problem with this board seems to be that the relay (black cube looking thing) soldered onto the board draws too much current for the size of its pins connected to the board. This causes those pins to get very hot; eventually the solder holding those pins to the board will degrade and fail. At this point you will receive the F01 error. If you remove the board and flip it over, you will see a scorched spot on the board where the connections have failed. The first time this happened I ran to youtube, broke out my soldering iron, and got to work. We had another four months of operation before the F01 error returned. I was preparing to deploy, and not wanting the washer to fail again with my wife home alone, opted to replace the control board.

I gave only 3 stars because I know it will fail again. This is a poorly designed product. Or perhaps well designed, if obsolescence was the goal.
