Dishwasher made a loud deep grinding noise

First of all, The part came in 2 Days which was amazing. I removed the jump up nozzle,lower washer arm and filter gaurd by unscrewing the cap (no tool needed).Then I removed the the Pump cover and secondary filter assembly by unscrewing the 6 screws with an allen wrench. I then removed the rinse arm then I unscrewed the discharge housing nut by hand. I then removed the three screws hold ing the discharge housing in place using a socket, replaced with new one and put it all back together the opposite of the way I took it apart. No more loud grinding sound. I hope this helps. It took about 15 minutes. I have a few extra pieces but the dishwasher dosn't seem to miss them. Just Kidding
