Whirlpool Duet Sport Washer Error Codes F-22, F-29 and F-01

This washer is about 8 years old, began getting an error code of F-33 last week. Book says it is a pump motor issue or a CCU issue, motor is not that old so went and bought a new CCU. Installed that yesterday and a new set of errors came up. Please help, I am trying to spend less than if I were to buy a new washer. I think the door lock system might be the next part to look at?? The puzzling part of this all is the F-01 that suggests the CCU is not working, it is a new and tested CCU.
