Product review (5 stars): It works!  Solved my F1 error code problem.
I have a Whirlpool WTW6600SW2 washing machine and the control board went on the fritz after a power surge.  It was giving me an F1 error code all the time, and I could get the washing machine to work by jumping through some hoops and babysitting it, but it was a pain (and it was hard to explain how I got it to work, which meant my housesitter couldn't use it, and that's not great when a pet has an accident and towels need to be washed).

I ordered this control board from Pandora's OEM Appliance parts - it was a refurbished part, and the order was fulfilled by Amazon.  When I received it, it looked new and was securely packaged.  I had my husband pull the washing machine away from the wall for me, and 20 minutes later I had this control board installed.  I placed the new control board on top of the old, and simply unplugged one cord at a time and immediately plugged it into the matching spot on the new control board until they were all transferred, then removed the old control board.  Ta-daaa.  I ran a load of laundry and it worked!  Woohoo!  Ten loads of laundry later, and it still works!

I put a heavy duty Tripp Lite surge protector on that outlet to hopefully protect against future power surges, to keep this control board safe.  I'm very happy with the new (well, refurbished) control board from Pandora's OEM - it was an easy replacement for me to do and avoid a repair company's fees.
