F6 E3 Error Code coming up? Whirlpool Cabrio top load washer possible fix for specifically WTW7040DW0

When all troubleshooting didn't work anymore (power cycling, button reset combinations and other tips from the web) it was erroring so much I was going to spend the $150 for the new board.

I decided I would take it apart as a FINAL resort. I unscrewed the back cover plate, removed the attached cables and screws to take off the touch plate, popped off the top carefully, and at a closer look I noticed the contacts were dusty. That is the first step in the phase 2 troubleshooting (deciding if a component is 100% dead and needs to be replaced) clean, reinstall, and test. Well I've never needed to do it again to the day.

I wouldn't think it would be dust but... It worked. It could have been that one of the contacts or something was loose and by dusting it off (It took a good amount of pressure to remove the dust) it was put back in place. Please know I was very careful as I know circuitry is delicate. I build and fix computers and more so I am not a stranger. You Tube vids though I need more work lol.
