HDA3420Z00BB Hotpoint Dishwasher - Instructions

The repair went really smoothly, I found a video on youtube for how to remove the dishwasher, and the video on the parts page did a great job covering replacing the motor. The repair went really well. As others have noted, it ran really nosily the 1st time, and a little the 2nd. After that, it ran quieter, and stronger than it has in the 4 years we have owned the house.

There is sufficient clearance to remove the motor and pump from under the dishwasher after removal of the front lower panels. This avoids the inconvenience of moving the dishwasher. Some ouch work required to remove some of the fittings as sight lines are obstructed - use a mirror to help. Installation is easier as all but one of the hose and pump clamps can be installed with the screw heads accessible from the front. Only installation issue was that the mounting holes on the pump body for the ground wires and the support piece had been drilled but no screw threads had been cut. Two minutes work with a tap solved the problem. One suggestion is to run a couple of loads before replacing the front cover to check for leaks. I did find one after the second load.

Removed and inverted the DW. Removed the impeller, grinder, screen and seals then the actual shaft seal. Replaced with new parts in reverse order. Instructions provided with the seal kit were simple and excellent. They were right to the point.

Most difficult part of repair was getting dishwasher out and in under the cabinet. Especially, feeding the copper water line from under the sink and then back while trying to align the connection. Installing the part itself was easy with good instruction for taking it off and reinstalling. However, since the motor had been upgraded, it required new connections. The connections were provided for this, but no instructions for the electrical connections.

Dishwasher is 22 years old and I'm 80 years old so it took longer, about 3 hours. After removing, turned upside down and removed old pump-motor assembly and replaced with new following directions [which took a little while to figure out; my assembly was quite a bit different from the replacement pump-motor]. Pleasantly surprised at how quiet the dishwasher now runs. Normally I would replace this old an appliance, but this unit has provision for inserting a wood panel that blends with the cabinets and a new GE dishwasher with this feature costs $1300 MSRP. I'm trying to save money for when I get old so I decided to do the repair myself. For $150 it was a worthwhile investment.
