Putting the new pump in place to test it only took about five minutes. The lower, front, kick-plate panel was already off because I had removed it to figure out what was so loud. The steps after that were:

- Unplugged it and the disposal under the sink (just in case)
- Pulled the wires out of the bottom front of the drain pump
- With a Philips screw driver I loosened the front hose clamp and pulled off the hose
- With the pliers I pinched the back hose clamp and pulled off the hose
- Twisted the pump off of its soft plastic bracket

To put the new one on I reversed the process.

Once it was in place and before I put the panel back on, I plugged in the dishwasher and started a cycle.


The pump was quiet but the person who installed the dishwasher in the first place had the drain hose resting on a spring. When the pump ran it resonated through the spring making a pretty loud noise.

So I unplugged it again, disconnected the hose, fed it under the spring along the floor and then reconnected it. When I plugged it back in and tested it, things were much quieter.

With everything in place I put the panel back on and was finished.

Note: I have worked on dishwashers before and most of the time they have insulation behind the kick-plate panel to quiet them, but this one didn’t. I will probably add that some time later.
