MDB125RHB3 Uni Dishwasher - Instructions

After moving the dishwasher out from the cabinetry, I removed the screws holding the pump in place. Pulling the pump from the formed plastic opening, I found a toothpick lodged in the pump housing. At the same time I noticed that the front o-ring was deformed due to being the incorrect size (too large). It was installed at the factory this way.

I went online to search for new parts. PartSelect was the second or third listing on the search page. I submitted the dishwasher model number and was taken to a set of parts illustrations. I was easily able to find the o-rings I needed.

I removed the kick panel at the bottom front of the dishwasher. Then using a flashlight and a cross point screwdriver, I removed the thermostat from about the middle left. It requires a short screwdriver, but not quite as short as a stubby. I unplugged the wires, noting that one of them was a little burnt looking. The burnt looking connector was still okay. I then installed the new one, with the green dot on the thermostat having the slightly burnt looking connector. Then I ran a load of dishes and the dishwasher worked as it was supposed to. It has worked okay twice since then.

I read the instructions that others had posted and completed the repair in less than 5 minutes!

1 Removed 2 screws to remove door panel so as to access back of dispenser.
2 Unplugged 2 color-coded wires attached to dispenser
3 Removed 6 screws attaching the dispenser.

Reversed these 3 steps to install new unit.

Easy. Don't even think of calling the repairman.

Replaced upper wash blade and used screwdriver to pop off rail stops to slide rack all the way out to exchange

Pulled old gasket off with small hook. Replaced new gasket by pressing in with my fingers.

Followed the YouTube instructions. Loosened 4 screws took off the front door panel and removed the old door and installed the new one. The video was very helpful!

Removed the two screws that mount to count top pulled the dishwasher out to see how the spring was attached , installed the new spring and the job was done the job it took about 15 mins. to complete.

I think the videos on the site are awesome. Made both repairs after watching them. They explain the repairs in a simple to follow way.

Removed two screws,one on each side of the bottom part of the door. The door cover then comes off. Then 6 screws hold on the dispenser. Shut off power and remove two wire connections. Replace dispenser. Replace lower door cover and two screws. Done.

1. Engage B.R.A.I.N. :
B: Break open the Box. You know you'll never get it back in
R: Read Instructions: It's not more packing material.
A: Assemble New One: Put it together just like the old one
I: Ignore Instruction: Seriously, sharp edges will cut me?
N Never listen to the wife Or at least pretend to be listening

New piece snapped right on

I removed the two screws and then moved the dishwasher out a little bit (about 6 inches). I pushed the dishwasher toward one side to make room for me to change the spring with my hand and repeated the same procedure for the other side. After the spring change, I turned an old dishwasher to a new one.

This repair project was easy enough that my 15 yr old son had it almost all done without me. The hardest part was getting the wires unplugged from the old latch. Once we got the pliers out to help us get a grip, everything went smoothly!
This was a quick and easy fix for an older dishwasher that still works!

Unhooked the dishwasher and took it out. Laid the dishwasher on it's back. Located the drain pump and took it off. Put the new one in it's place. Hooked the dishwasher back up and tried it out. Everything sounded and ran good. Easy assembly. Took 30-40 minutes if that.
