Killed the power and shut off the water. Unhooked and unplugged power, hot water and drain connections to move washer to middle of floor for easy access to all sides. Taking out the the main pump/motor assembly (the "Assembly")required taking out the flat white hot water tube that feeds the upper and middle sprayers. So, I started by taking out the two trays. Then, took out the lower, middle and upper sprayers. Then, tipped the dishwasher onto its front and disconnected the hoses and several electrical connections from the Assembly. Also, unhooked the drain pump motor and impeller from the Assembly since these are not included with the new Assembly. Took out the three sliding retainers to release the Assembly from the bottom of the dishwasher. Took a little gentle coaxing to release the seal between the Assembly and the tub bottom. Took the Assembly apart and found that the problem was the shaft bearing (ball bearings) between the motor and the impeller had rusted and subsequently failed. Therefore, buying just a new motor would have not helped. Inserted the new Assembly into place from inside the tub. Because of the tight seal, the Assembly had to be carefully placed into the tub opening and the seal gently pushed into place by working all the way around in 1 inch intervals. Took about three trips around the seal of the Assembly to ensure a tight, even fit. Otherwise, working unevenly around the perimeter will bind the Assembly and you'll have to remove it and restart. Once in and seated evenly in its place, reconnected the hoses and electrical connections. Installed the drain pump motor and impeller onto the new Assembly. Tested the unit for proper operation and leaks. Found no problems. Then re-installed the water tube, sprayers and trays inside the machine. Helps to jot down steps taken to disassemble so you retrace steps to re-assemble.
