Have a GSD3410 dishwasher for 12 years with no problems. Was not draining properly so I took the base cover off and heard a sporadic clicking sound when the pump was running. Assuming it was the pump, I replaced it. New pump, same problem. Drain is clear. Only makes the noise when the pump is running. Sounds something like a plastic gear that has lost a tooth and is flailing around. Any suggestions? The new pump came with a new drain solenoid and all the parts attached. 3 hose clamps and a couple plug in wires and it was changed (very simple).
