MDB421RHS1 Frigidaire Dishwasher - Instructions

VERY simple---unscrewed three screws on the broken part (the little nubs that held on the bottom spinner were broken off), screwed the new one back in, re-attached the spinner.

I was VERY pleased with the customer service and quick shipping (ordered on Sunday night, the part was delivered Wednesday morning). I would definitely recommend this site to anyone, and would use it again. Five Stars!!!!

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.

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!!

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.

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.

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

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!

The old gasket was worn. I pulled out the old one, put in the new gasket. I trimmed the ends to fit and that was it.

Took out the two retaining screws and pulled the unit forward. Took the old door strike out and put in the new one. This site is where I go for all my appliance repair parts!!!

Pulled off the old gasket and replaced it the same way with the new one.

Pulled the old one off and pressed the new one on (plastic clips hold it on). Dishes much cleaner now.

Replacing the part was easy. Just pop the old one out and pop the new one in. This item fixed my leaking door problem. The old arm had fallen against the heating element, which burned a hole through the end. Water was shooting out that hole and leaking under the bottom door seal. Replacing the door seal did not help, but replacing the arm fixed the leak.
