The dishwasher made a loud grinding sound when it ran. We looked at new dishwashers and they're still basically the same, but the $$$ is so high. We looked at the reports PartSelect.com and after reading the reports, decided it was the pump motor/impeller unit and ordered it online. FIRST, read all the other installation stories. It will save you time. You will save unnecessary steps. In the end, it wasn't actually as bad as it sounded. So, here are the steps I took to install the new pump motor with impeller unit. ONE: turn off the water supply TWO: turn off the power (I had a dedicated circuit breaker just for the dishwasher)THREE: disconnect the water supply at the pipe(not the dishwasher) FOUR: Disconnect the drain hose at the drain(not the diswasher)FIVE: remove whatever screws are holding the unit inside the base cabinet SIX: pull out the diswasher(carefully watch the wires, hoses and insulation) SEVEN: tip the dishwasher forward (lay it on rags, watch for water)EIGHT: Disconnect the electrical supply plug to the pump (it's a plug-type connection, squeeze the edges to release)NINE: remove the one bolt holding the motor on the pump assembly and the heat sheild(you'll need a ratchet with extension) TEN: turn the pump motor counter-clockwise and pull it off. ELEVEN: align the arrows on the new motor of the pump and mounting assembly. TWELEVE: clean the o-ring on the pump and lubriate with drying agent THIRTEEN: place the motor on the pump assembly rotated counter clock-wise a bit past the bolt hole and press until it seats. FOURTEEN: turn the motor clock-wise to engage the locking mechanism and align the bolt hole. FIFTEEN: replace the bolt and heat shield. SIXTEEN:reconnect the power plug SEVENTEEN: tip-up the dishwasher, slide the unit back under the cabinet. EIGHTEEN: reconnect the drain, water, and power. NINETEEN: turn-on the water and restore the power TWENTY: test(start a wash cycle) the unit to be sure it doesn't leak. TWENTY: if all is good, replace screws holding the dishwsher in the cabinet(otherwise you will have to back-track to find your error - I didn't). And that's it! Now it's running smooth and silent, just as before. Good luck!
