Hi All, Whirlpool Duet Sport FL Washer Model# WFW8300SW02. F-22 error code, replaced door lock and still no spin. I did the test that Durham talked about: Disconnect M13 connector from CCU, Try to start cycle, hit the cancel button, and if it unlocks it is the MCU. It did NOT unlock. When I do the Diagnostic test by pressing a button for 4 seconds, release for 4 seconds, etc. "88" shows in the diaplay, then the error code (F-22), then I press the button again to start the Manual test and the door locks, the Rinse/Spin light flashes and then nothing. it will not do the Manual Test. Pressing the Cancel button or the power button does nothing. I have to unplug the unit to clear it. Each time I try to enter the Manual Diagnostic Test "88" shows and all lights flash, then the door locks, then nothing. I also tried the other test that bypasses the Service History Test: Push Power, Select Clean Washer cycle, press Extra Rinse four times. Still the door locks then nothing. Pause/Cancel will not clear it. Does this point to control board problem? Thank You Very Much, Bob
