I looked at a whirlpool duet for a customer and the original problem was a f01 code upon entering the drain spin cycle. Replaced ccu and it immediatley blew the new ccu upon entering the drain and spin. I thought there may be a short to ground somewhere so I replaced the ccu the wire harness and the mcu for good measure. when it entered the drain and spin this time the machine just shut down. Upon further inspection the drain pump motor windings showed signs of arcing so I replaced the drain pump motor and ohmed out the wire harness while attaced to the motor by taking it off the ccu and the wire harness and drain motor ohmed out good at 12 to 13 ohms. Now the machine will drain a little rotate the basket a little, unlock and relock the door, and then shuts down. after running a diagnostic it shows a f33 code which is a pump drive system error. I checked the connection to the ccu and the drain pump and connectoins are in place. I am at a loss from here. Any help will greatly be appreciated.
