Controll proplem?

Hi, need help. Started with "LD" error code. Lines and filter clear, replaced pump and motor. Ran 1 Quick Wash, with new pump and motor installed, worked fine. Ran 2nd Quick Wash, machine stuck in rinse cycle, timer stuck at 12 minutes. Cancelled cycle. Ran Quick Wash again, machine stuck in rinse cycle with timer at 12 minutes. Ran "auto diagnostics" everything seemed fine, display ran down to 0. :confused:
