Two weeks ago this Saturday my cousin loaded the dishwasher and ran a cycle and it hasn't worked since. Maybe a coincidence, but I'm not sure. It kicks on like normal, fills with water for about 30 seconds and then makes a loud humming/buzzing noise. It just won't fill. I replaced the water inlet valve, and it appears that the float and float switch are performing correctly. I had an electrician friend come over with a continuity tester and it's testing out just fine. I've checked for clogs in my spray arms and I've pulled all of the components down to the drain bowl in the bottom of the dishwasher and I see no visible clogs. whay did I miss? What else can I try? I'm not in a position to replace this dishwasher, so ideally I would like to fix it. Any thoughts? Thanks in advance.
