Dusty B Apache Junction , AZ August 13, 2014 Appliance: Whirlpool Washer WTW6300SW0 Whirlpool Washer Wtw6300sw0: Kept shutting down with multiple codes (notorious f codes). How to replace Control Board. Washer had multiple codes popping up when purchased used. First thing found the basket was jammed throwing out of balance code removed article of clothing that was stuck between the basket and cleaned the contact areas so the basket would float then replaced the suspension rods then still kept getting the f code for the control board so replaced that has been working perfect so far time total for all repairs done in stages about 2 hours mostly on freeing up the basket. Rods took about 20 min. Control board took about 5 min. PS.
