MDB120RFM1 Frigidaire Dishwasher - Instructions

Easy as pie. Just turned off water and electricity. Disconnected hoses and wires and replaced with the new valve.

First point of leakage was the door. Turns out that a gasket at the bottom of the door functions as a wave trap. As the bottom sprayer spins it sprays against the door and creates a small wave of water this gasket was starting to disintegrate, it was letting water surge over the small tray at the doors bottom. Easy to replace just pull down and remove press fit on inside door bottom. Only when this was replaced did I find the real leak but not until I guessed at the tub seal as the leak. Very hard to see where the water really comes from! Turns out it was not the tub seal but a clip that holds the heater element got smashed down from a dropped dish rack at some earlier time and this caused the heat to increase at the clip and eventually heat the clip to extent it melted the tub directly under it. JB Weld to the rescue and we have a waterproof tub again. Well almost! The tub gasket resisted my best efforts to seat correctly and thus required a new tub gasket, still hard to seat but after 2-3 attempts we have a winner. Total cost about 50 bucks vs. 6-700 for a new unit. Wife is happy!!

It was super simple. I popped the clips that were holding the old spray arm on and then popped the new one in place.

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

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!

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.

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 watched several videos of people replacing this gasket easily, but we had trouble. The old one came out easily. The new one just slipped into the crack, but it kept going and ended up on the inside of the door. We ended up taking the outside panel off to get the gasket out. We tried to fit the thing into the slot, but it kept coming out the other side. I finally came across someone who had had the same trouble. By feel only, you can feel a slight ridge on the top side of the lower door and I had to press the gasket against that ridge. It was not a very noticeable ridge, but it holds the back (slot edge) against the door so that the gasket stays put. When we figured that out, the repair went smoothly. I am running the dishwasher now and so far, so good.

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.

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!

if the wire they snap on was bent it needs to be straightend.......they just snap on. easy to install but wish they had better wheels so this problem would be solved. My 2 sons have same brand dishwashers and have same problem.

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.

First, I was so pleased to find these parts at such reasonable prices! Sure beats replacing a dishwasher in terms of money and labor. I'd already studied the online instructions a couple times before ordering and checked to make sure my racks dis-assembled as shown. They did, I ordered, got the new racks within days and installed both in under ten minutes. Great service and awesome installation videos. I will definitely check this site if I need replacement parts for anything else in the future. THANKS so much!

Easiest repair EVER!!! You just pull the old spray arm off (be sure to keep all the smaller pieces that click it into the bottom of dishwasher) and pop the new one in. Done!
