MDB121RFS2 Frigidaire Dishwasher - Instructions

The Inlet valve was leaking. I removed the old valve in less than 30 min.Note: need bright flashlight! It could have been quicker but I had to lie on the floor and squeeze my big hands under the opening (kick panel). Once I got the two small bolts out, I was able to manipulate the valve out from under the dishwasher, then I carefully removed the two lines. I received the part in 5 days and installed it in 45 minutes. It could have been a faster installation, however I was not about to pull out the whole dishwasher. Again, I was able to manipulate the new valve back in & tighten then test everything.(note: need a bright flashlight to see underneath) I immediately ran a load of dishes and Presto! No leaks and runs like a Swiss watch!

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

My daughter held the flashlight steady as a rock as I hooked not one, but two new hinges in place. Throughout the whole ordeal neither of us complained or lost our resolve. We conquered!

Ordered the parts, put into place and that was it...very easy...had to undo the upper rack spinner wash blade but was easy to remove and put back onto the new rack...

Turned off elecrtic and water to dishwasher and pulled dishwasher out from under cabinet. Removed broken hose using pliers to open hose clamps.
installed new hose.

Used pliers to remove old seal. Keep seal in position, note the notch facing the hole. Align the new seal, press it in, the notch helps align. Mine slipped in easy

I unclipped the plastic pieces at the front of the rack. This was very easy. Then I removed the old rack. I then removed the water sprayer from the old rack and placed it on the new rack. This was simple and I unscrewed the water sprayer by hand and snapped out. Putting it on the new assembly was very easy. Then I placed the new rack on the two stainless steel sliders and refastened the plastic clips at the ends. It was no problem.

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

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!

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.

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.

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

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.

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