Dishwasher Sump Seal
Genuine Samsung part
By: Samsung
Part Number: DD62-00050A

Prevents leaks and maintains water circulation in your dishwasher. Replace if you notice water pooling or weak spray. Confirm fit with your model number.

Do-It-Yourself Stories from Customers like You The "heavy" load light was blinking   Mark K. • Everett , WA • January 30, 2017

Research indicated that it may be a moisture sensor failure or a leak. It ended up being a leak from the oil seal on the motor shaft. A small piece of plastic made it's way into the system. The hot water softened it enough that it wrapped around the motor shaft, re-hardened, then tore into the shaft seal. I fixed it by replacing the shaft seal, moisture sensor (corrodes when it gets wet), and replaced the sump seal since I had it disassembled. Read more

Dishwasher Spray Arm Retaining Nut
Genuine Whirlpool part
By: Whirlpool
Part Number: W10877037

Upper spray arm keeps falling off? This retaining nut secures the dishwasher spray arm to prevent detachment during wash cycles. 2-minute fix.

Do-It-Yourself Stories from Customers like You Upper spray arm fell off   Christina L. • Castle Pines , CO • November 24, 2015

Ordered a new spray arm (because the old one finally broke into two pieces after falling off several times, and this time the arm melted next to the heat coils) AND ordered the new nut because of all the information posted by other users (thank you). Had to use pliers to get the old nut to unscrew, but once it was off, getting the new nut in was easy. Then popped on the new spray arm, and voila, the next load of dishes came out much cleaner! Yay!

Do-It-Yourself Stories from Customers like You Problem with detergent cup lid.   John M. • Craig , CO • November 27, 2017

The foam was shot on the detergent cup lid. Hard as a rock. Causing caking problems, dribble down the inside wall of the door and leaving lumps of detergent. Cut the door in half wit aviation snips and pulled out the two halves. Discovered at this point that the spring had gone soft. Bought one ahead of time, so I was set. Put the spring on the left pin, put the spring pin in the door, slipped the door into place (open) and put the right pin in with pliers. Door snaps open now. Read more

Genuine Samsung part
By: Samsung
Part Number: DD32-00005A

This sensor monitors the water temperature inside your dishwasher during wash cycles. It sends temperature readings to the control board to ensure proper cleaning and sanitizing. Replace it if your dishes aren't getting clean, water stays cold, or you see error codes related to temperature.

Do-It-Yourself Stories from Customers like You Ie error code first during wash then immediately after powering on   Matt R. • North Yarmouth , ME • August 22, 2015

The model number on the dishwasher did not have a -0000 or -0001 on the end of the model number so I bought the part for both models. I assume if yours doesn't have it, then it is the -0000 model like mine, which of course means the more expensive part. You can always buy both and return the one you don't need. Replacing the temperature sensor was fairly simple - disconnect power and water, pull the right-side panel off, move the noise filter out of the way, turn the sensor a quarter turn... Read more

Do-It-Yourself Stories from Customers like You Soap dispenser flap didn't open   Bill R. • Austin , TX • April 06, 2014

Removing the door panel was easy -- remove 6 Torx screws, and the panel falls off. Next you need to remove an electrical plug and 2 individual wires from the old dispenser. The plug came right off, but the wires were not easy to access, and they fought me more than I expected. With some pliers and wiggling, they eventually let go and came free. The dispenser is held in place with 6 Phillips screws through 2 removable metal brackets, and those came out easily. The toughest part of the job... Read more

Do-It-Yourself Stories from Customers like You Ice dispenser was skipping so not dispensing ice   Del H. • Midlothian , TX • September 03, 2018

The problem was that the motor coupler & shaft had a tiny bit of rust at their union. With the weight of the ice bin it rusted in the lowest position. This didn't allow the motor coupler to float on the shaft. There is a spring inside the shaft that pushes up on the motor coupler keeping it engaged in the ice bin coupler above. This coupler in turn rotates the auger in the bin to dispense the ice. I removed the motor coupler & shaft, tapped the coupler loose and filed off the rust. This allowed... Read more

Do-It-Yourself Stories from Customers like You Rusted tines on upper and lower racks   Michelle L. • Sussex , WI • October 19, 2018

Kitchen Aid dishwasher is 11 years old, and the tines have been rusting and biting the dust one by over the last few years. Rather than further destroy my dishes by abrading them with rust particles, I decided to get new racks. They are terribly expensive, and I pondered getting a new dishwasher. It wouldn't be that much more expensive. But I love mine and how well it washes. It has a stainless interior, and all of the seals are in excellent shape. I didn't need any tools. (Although I'm a...
