MDB421RHS1 Frigidaire Dishwasher - Instructions

Located where the dishwasher was leaking from and by referencing the parts catalog determined that it was the water valve. I ordered the part from Parts select and replaced the part when it arrived. Replacing the part was very easy and I now have a working dishwasher again.

The original lower spray arm had one end break loose the metal retainer end. I used a temporary small hose clamp to fix as I waited for the new lower arm to arrive.

The design is very easy.... pull up on the OLD and then just push DOWN on the new arm into the bottom.

I simply had to take the replacement rack out of the box and put it in the dishwasher. I was sent exactly the right part, as ordered, and had no difficulties at all.

My dishwasher started leaking at the beginning of the summer. We didn't know what to do, but didn't want to call an appliance repairman. Towards fall, a friend came over and pulled it out and found the heating element brass nut which was broken. We put it back in and washed dishes the old-fashioned way for another 3 months after that. I asked at my local hardware store for the part, and thought about trying one of those big-box do-it-yourself stores but never got around to it. Finally after getting sick and tired of doing all the dishes in the house by hand, I found your site, and the part I needed and ordered two (just-in-case). A few days later, we got the part, I pulled the dishwasher out again, screwed on the new nut by hand and put it back into place. We're in business!

I measured the length of the gasket, using the old one to measure the length. Cut it to that length and installed it. VERY SIMPLE TO DO! But it didn't stop my leak--turns out there was a small leak in the bottom of the tub that was easily fixed with some silicone. The dishwasher's like new now!

Replaced racks and removed silverware holder, glass holder and water sprayer from old rack and attached to new rack with very little trouble. The only thing different with the new lower rack, is that it does not have the collapsible racks to use for pots.

turned off water supply. replaced the water inlet valve. replaced the updated lower spray arm.
works like new again!!

Easy as pie. I tokk the screws out that held the dishwasher to the counter top out. Then removed the screws holding the strike in place, inserted the new one, installed screws and then rescrewed the 2 screws backintothe countertop. Job done. All told 5 minutes.

First I pulled out the old gasket and replaced with the new one. The new one is too long on purpose but only had to be trimmed a little for a perfect fit. Very easy and now no leaks.

This was great! Removed 3 screws, took out old broken part, set in new part and screwed tight! 1 2 3 and done. Very Fast shipping less than 24 hrs.. WIFE IS HAPPY. Ted W.

It was a snap. Just pulled the spray arm out, un-snapped it from its holder, snapped the new one in and inserted it back into the dishwasher. Saved $$$ doing it myself.

I removed the three screws that held the stem assembly in place, removed the old stem assembly and replaced it with the new one. Replaced the screws and began using the dishwasher again.

I used the PartSelect repair video online to show me how to fix the dishwasher. I needed a spray arm and support. Excellent video made the repair quick and easy.
