There were 4 zip ties holding old silverware basket on to bottom rack snip them, remove basket install new basket with zip ties both ends 2 more in middle about 1-2” apart. Try to install ties about 1/2 way up on basket so it doesn’t get top heavy.

I followed the instructions in the video. It was really easy and took less than 15mins. Very happy with the part.

Isolated the leak and found the nut had split thereby allowing a loose seal and water penetration. Ordered 2 nuts just in case the other goes and the installation was easy. Unplug the unit, remove baseplate, remove screws under the countertop, and slide the unit out a bit. Use needlenode pliers to remove terminal connection and replaced nut. Reverse it for assembly. 3 minutes tops $6 later it is done. Easy money saved by a DIY.

shut off water supply, unhook water line first so i could pull the washer out first. pull washer out and the valve is on the lower left if your facin the washer. easy to get to and very simple to change out.

The repair was relatively easy and I probably saved enough money as to not have to buy another dishwasher. The part alone was $42. A service call and installation would have made it not cost effective to fix.
The control panel is loosened with phillips head screws on the inside of the door. The latch is attached with the "star" shaped screws. I did not own one of these drivers so I had to leave the house to get one. I used pliers to disconncet the clips from their connections as to not pull the wires from the clips.

Removed the front panel below door, 4 screws. Removed 1 screw that help relay on frame. Moved 3 wires from old relay to new. Installed relay to frame, installed panel and done.

Removed the broken part and disconnected the four wires. Installed new part (two hex head fasteners) attached wires - good to go!
Quick delivery on the part allowed for dishwasher to be down for only a few days after the part was ordered.

DISASSEMBLY
- Switch off circuit breaker for dishwasher.
- Remove lower front covers from washer to observe motor (for later steps) and to clean-up water.
- Remove top and bottom dishracks.
-You may want to take pics of the placement/orientation of components in the following steps as you disassemble them for reference during reassembly.
- Remove spray-arm base from pump housing.
- Remove and discard impeller— put a screwdriver in the impeller grooves to prevent it turning as you loosen the screw.
- Remove impeller, O-ring, and blade. Discard impeller and O-ring, but keep blade (I couldn’t find the O-ring; it had probably disintegrated).
- Remove pump housing, pump plate, and gasket.
- Use two flat-head screwdrivers on opposite sides of the rotor to pry it off the motor shaft. Be cautious not to damage the area around the motor shaft—wood can be used to protect the area and provide better leverage. If the rotor can’t be removed, a chisel or hacksaw can be used to split it before prying it up— be cautious of the motor shaft when splitting the rotor. Discard the rotor.
- Locate the upper seal, note its orientation (cup-side-down), remove it, and discard it (my upper seal was in the recess in the bottom of the rotor).
-Drive the shaft-key (small metal tab) out of the shaft groove using a hammer and flat-head screwdriver and discard it— the new rotor has a molded-in tab that will slide into the groove in place of the shaft-key.
- Remove ceramic ring from motor shaft and discard it (my leak was caused because the ceramic ring was broken in half).
- Use a flat-blade screwdriver to pry loose the lower seal—before removing it from the shaft, note its orientation (wide-side-down). Be caution not to damage the area around the motor shaft—wood may again be used for protection and leverage.

CLEANING/PREP
- Clean shaft with wire brush, white vinegar, and a rag (you may not need the wire brush if the shaft is in good shape, but my motor shaft was heavily corroded/rusted and I needed to smooth it to prevent it damaging the seals). Clean groove in motor shaft with flat-head screwdriver and rag.
- Use a rag and white vinegar to clean motor shaft recess and pump housing seat. The bottom of the motor shaft recess must be clean and smooth for the lower seal to seat properly.
- Clean pump plate, gasket, blade, pump housing, and screws with white vinegar and a plastic-bristled brush.

ASSEMBLY
-Wet new rubber seals, new ceramic ring, and new rotor with water to help them slide into place.
-Refer to pics taken during disassembly as needed for the following steps.
- Place new lower seal (wide-side-down) over motor shaft in bottom of recess.
-Push new upper seal (cup-side-down) into recessed area in the bottom of the new rotor.
-Push new ceramic ring into upper seal (cup-side) in bottom of rotor.
-Align groove on motor shaft with tab in rotor (a mark on the outside of the rotor shows the tab’s location) and seat rotor on the motor shaft by hand. Verify that the motor turns when the rotor is turned by hand. If not, remove the rotor and reposition it so that its tab slides into the groove in the motor shaft.
-Place gasket, pump plate, and pump housing in position. Start pump housing screws, but leave them loose.
- Place blade and new O-ring on rotor.
- Place new impeller on rotor and insert screw. Tighten moderately — overtightening could cause leaks. Hold the impeller by hand to prevent it turning as the screw is tightened— do not use a screwdriver to prevent the impeller turning.
- Finish tightening pump housing screws.
- Seat spray-arm base on pump housing and insert/tighten its mounting screws.
- Switch on circuit breaker for dishwasher.
- Start washer and watch motor to verify that shaft seal is not leaking. Run a full cycle to rinse the new parts and remove debris and vinegar residue. Continue to observe motor shaft area for leaks during cycle.
-Replace lower front covers.

After getting a totally incorrect length of hose from partselect.com . Went to local hardware store and bought hose for $3.00 vs $20.99 + $10 shipping!
Partselect sent replacement hose of 24 1/4” vs the original hose of 27”. Good luck getting any response from them once they have your money!

FIrst I had to turn off the water supply, remove the bad part and cap off the copper water line.
I found the correct part on line and ordered it. When the part came, I uncapped the water line, doped the ends and refit the valve. Turned the water on an voila!. I actually did it! I was pretty proud of myself. It only cost me the price of the part and not a plumbers fees as well.

The spray arm had become damaged on one side -- one side had apparently melted off. I replaced it, and it seems to have fixed the problem for now.

The new roller just snapped in place.

Very easy to remove old broken door latch assembly, easier to install replacement. With door fully opened, I removed the 8 screws holding down the whole front casing, including the controls casing. Removed 2 Torx screws holding door latch assembly and then made sure that I marked all 4 wires before disconnecting them from door latch assembly. Connected wires to new door latch assembly, secured it with the 2 Torx screws, aligned and secured the controls and front cover casings with 8 screws. Done within 30 mins. Thanks guys for posting how-tos and thanks to PartSelect for a very fast shipping!!!

just slid the wheel on.
