Washer works fine except no final drain. Gives code F28 and once gave F11. Cleaned trap and visually inspected all componets. Works fine up until this point. Unplugged and reset result the same
Any ideas appreciated

There should be a tech sheet under the top cover. This will explain the error codes for you and give you a way to put the machine into diagnosis mode.
The F11 code is a communications error, your CCU is not getting the right message from the Motor Control Unit. Try checking all of the wiring between the CCU and MCU and then take off, clean with contact cleaner and reseat the connections on the CCU and MCU.
If it is still giving you a problem consider replacing the MCU. Not a sure fix, but a likely one.
