MDB421RHS1 Frigidaire Dishwasher - Instructions

Removed old spray arm, fitted new spray arm. VEry easy. Sorry I didn't do it months ago

First I removed the bottom dish rack to gain access to the spray arm. I proceeded by pulling straight up on the bottom spray arm, it disconnected with gentle force. The replacement part was not identical, so I determined that it would work by inspecting hole patterns and heat shield configuration. Then I gently pushed the new spray arm onto the water supply tube making sure that the spray arm snapped into place. Due to extremely fast ground shipping (less than 20hrs from order to my door) the repair was done within 24 hrs! Boy...was my wife pleased!

I disconnected the power to the machine. Removed the bottom access panel and screws holding the dishwaher in the cabinet opening so I could carefully slide the dishwasher out.
Taking note of the pump position at the bottom of the dishwasher I removed the two wire leads, screws and hoses(pliers). I installed the new part in the reverse order and was able to run the dishwasher for a cycle while it was out to make sure there were no leaks.
Dishwasher runs great and the dishes seem cleaner. Fingers crossed.
Thanks.

This was too easy. I pulled out the bottom rack, spread apart the two clips which are at the bottom of the spray arm with my fingers and pulled out the old broken spray arm. The damage was visible. Then I took the new spray arm ( which looked different but still fit nicely) and gently pushed it into place. Done!

Popped off the old spray arm ... INTENTIONALLY, and put new one in. Had to lift off small strainer to allow old arm to release! Be sure to turn arm until it clicks into place, return small strainer/clip, and you are in business!
Most trouble I had was getting this old bo
y up off the floor afterward.
Dished so much cleaner now!

It is rather easy to repair. After you remove the screws that secure the top of the dishwasher to the countertop you can slide the disherwasher out far enough to gain access to the hose. The hose pulls off after you slide the spring clips down the hose far enough so they no longer grab. Then simply reverse the order and you're done. Less than 30 minutes and you should no longer have to hand wash your dishes!

replaced with new lower rack, out with the old, in with the new! Shipping was great new part arrived in 2 days! Great service, and will use again for all parts needed in the future, and will tell everyone about this site! Thanks a bunch!

The nut was split down one side, so I first tried to sauder the nut back together. Saudering never goes well for me anyway, but I couldn't get a good enough seal around the nut to make it fit tightly. Then I had to cut off the clear plastic shield to get down in there, just before realizing you could just pull the white wire firmly and it would come loose from the nut. All I had to do then was unscrew the original nut, and screw on the new nut. Then, luckily I had mistakenly ordered an extra clear plastic shield and could replace the one I had previously cut. Dishwasher now runs like a charm!

Manually took off melted parts and replaced them with the new ones.

#1 rule, make sure you valve off the water before removing any hoses. Remove wire trays inside dishwasher and then pull out dishwasher far enough to disconnect water line and power cord. Remove center piece and screen covering sump inside the dishwasher. Turn dishwasher on its side and remove hoses to sump and pump. Disconnect power to sump pump. Loosen retaining nuts that secure the sump and remove. Replace old gasket on sump with new. Turn dishwasher upright. Be careful with placement of new gasket when reinserting sump so that the gasket doesn't come out of position and the sump is centered properly. Secure with retaining nuts from bottom. Reconnect power connector and hoses to sump. Pour enough water into the dishwasher to verify gasket doesn't leak... look with flashlight under dishwasher for signs of water dripping from sump. Reinstall screen and centerpiece in sump inside the dishwasher. Reconnect water line and power cord. Run through wash cycle while monitoring for leaks under dishwasher. Reinstall wire trays.

Piece of cake as long as you get the gasket installed properly and the sump centered correctly... do not overtighten the retaining nuts or it may force the gasket out of position when the screen is secure with the center locking piece over the sump.

I turned the power off at the circuit breaker. I then took the access panel off the dishwasher at the bottom. I pulled the wire off the connector. I used a plied to remove the broken washer and replaced with new part. I put everything back in reverse order and ran the dishwasher. I than checked for leaks over two days while the machine was running and everything was fine. Thank you Parts Select for saving me $500!

Removed old filters and trap and installed new ones.

Very, very easy. Pop off the old wheels and snap the new ones into place on the rack.

Simple repair.

My upper spray arm attaches to the upper dish rack. It comes in four parts: the spray arm, the bracket which attaches it to the rack, the water funnel, and a plastic nut that holds the pieces together. The nut was worn and wouldn't hold so I replaced that piece and it works great. It took less than one minute to fix.
