I have a GE dishwasher model PDT715SYN3FS and dishes are not getting cleaned. The motor was replaced recently, but sometimes the spray arms will spin and sometimes they won't. In the beginning of the cycle, I can hear the spray arm spinning, but seconds after closing the door, I can hear the motor humming but neither spray arms are spinning. There is enough water getting to the unit, and when the spray arm spins, the pressure is pretty good. What could be causing this issue and what steps should I take to troubleshoot it?
