Its showing F01 error code I replaced the ccu unit washer still will not finish wash Its stays on delay 2 minutes left. I also noticed it stays locked and won't unlock. I tried everything checked wires . This all started when I had to replace the washer pump wich was broken . T bought a new one but know I have the issue with the F01 code what else can I do?

Before you condemned the pump did you check it or the pump relay with a meter? You cannot fix modern machines by replacing parts; that comes after you check them with a meter and find them to be bad. Look at this: https://dl.dropboxusercontent.com/u/8010163/Understanding%20automatic%20washer.pdf
