My Whirlpool duet won't spin, No error codes

I have a Whirlpool Duet Sport that is having issues. First it wasn’t spinning out the clothes, and I got error code F01, so I replaced the CCU. I did the diagnostic test and it ran with flying colors…so I did a load of laundry and now it won’t spin out the clothes. I took the clothes out and tried the diagnostic test again, it ran correct one other time and now it won’t go thru the spin cycle at all. I clean out the drain filter, which had a bunch of change and gunk, and it still will not spin. I get no error code, so I am not sure if it is the MCU, because it the drum will rotate during the diagnostic test. I did find the hose from the drain pump has a leak, so I ordered a new one, just waiting for it to come. Any ideas? Before I call the repair man.
