F11 showed up at the end of a cycle. Washer me have been loaded a little heavy but not bad. Ran diagnostic test and it will not get past C:01 without giving the F11 error. If I manually advance to each sequential check (C:O2, C:03, C:04, etc) It will begin each check but shortly after starting gives the F11 error. Interestingly, when trying C:07, nothing happens at all It's just throws the F11 after several seconds. So should I replace the MCB or the CCU first?
