During the "Add a garment/Wash" cycle I'm getting an F followed by an H (or reverse) code. No numbers, just "F" and "H". The washer will not move past this till I pause it then restart it and it usually goes away. Today I had to do this twice to clear the code. This has happened 3 times over the last two weeks (I do at least 7 - 10 loads a week) - any help would be appreciated. I've lost my manuals somewhere and have no idea what's going on here.
