Product review (5 stars): No need to remove dishwasher to replace this pump
For my model of Frigidaire dishwasher, I was able to replace the pump without disconnecting or moving the dishwasher in any way. I simply flipped off the circuit breaker, then lay down at the bottom of the washer and got to work.

I removed that sheet metal covering panel at the bottom, unplugged the two electrical connectors from the pump, used an allen wrench to remove the two screws from that metal bracket which holds the pump in place, slid a large dinner plate under the pump to catch water, and pulled the bracket down.

Then I wiggled the pump slightly out and loose, so that water slowly drained onto the dinner plate. When the plate got almost full, I pushed the pump back in to stop the draining. I carefully slid the plate out, lifted it, and dumped the water in the sink. I had to repeat this draining method a couple times because my plate couldn't hold all of the water that was sitting in the bottom of the dishwasher.

Next I pulled the pump all the way out (turning it to avoid the water supply line), and slid the metal bracket off it. I reached inside the hole in the bottom of the dishwasher, where the pump had been, and used paper towels to clean it as best as I could. I smeared liquid dish soap onto the parts of that cleaned area, where I guessed the pump touches it.

I also smeared that soap on the o-rings that came with the new pump, then slipped them into place on the pump. I slid the bracket onto the new pump. I turned and angled the new pump into place, and pushed it in. I reinstalled that bracket, plugged the wire connectors in, and turned the wall circuit breaker back on.

I didn't immediately reinstall that bottom cover because I wanted to see under the dishwasher when I next washed dishes, to check for water leaking.

The pump has worked quietly and as expected.
