The dishwasher will fill with water and drains well. When you start a cycle, it will fill until it gets ready to start the circulation cycle (washing cycle), then it will stop and display the F4 Code and we hear 4 "clicking" noises and then nothing more. We have replaced the intake valve and it did not fix the problem. Found out how to run the dishwasher through it's fault tracing system when it gets to the circulation cycle it will pump water into the spray arms and start washing. It just won't do it on a regular wash cycle.
