after removeing the mounting and trim screws,water lines and associated wiring, the unit slide easily from under the counter then the fun began.
After several years of being exposed to the terrible water here the parts had become covered in lyme scale.
to make a long story short, most of the parts came out with minor difficulty however the pump motor shaft had corroded and lodged into the pump impellar.
This made removal of the pump motor impossible with out cutting off the end of the impellar and driving the pump motor shaft out.
This is NOT something you want to do.
It seems the engineer who designed the pump motor had it's casing made of plastic.
Driving the pump motor shaft out of the impellar caused the back of the motor houseing to break thus rendering the pump motor useless.
Lesson: If it becomes necessary to cut off the impellar of in the pump housing you must completely split the impellar in two parts.
This I repeat is NOT something you want to do.
I recommend replaceing both motor and pump assembly as a unit.

Got the new door and tried to put it on. The door went on very easily. However, there's a spring that opens the door when the main wash cycle comes around. I never did get that spring right. None of the drawings showed the correct position and after an hour of trying to get it to work right, I gave up. The door comes open slightly (but not because of the spring) when it's time, and the liquid soap runs out due to gravity. But I wouldn't try to use soap powder because the door doesn't come open far enough.

No Water supply to Dishwasher. Turned off main Supply valve under sink.First took off old Diswasher supply valve and repaired it by cleaning it and it worked for two weeks. I ordered the part, but then cancelled it and Partselect service was great and cancelled it immediately. After it went down after 2 weeks I re-ordered it and it came in 4 days.
To Take this part off I removed mounting scews with nut driver, disconeected electronic plug connector, removed the compression fitting from the water supply and removed the outlet hose..reversed all of the above to install.

Very easy repair. I gently removed the rubber seal at the top of the tub. here I found the 2 holes to screw the new plate into place. Put the seal back over the hole and job done. Thanks for all the help from the very supportive staff. Yes, a woman did this repair. Dishwasher working like brand new!

The repair went well with the major problem being I replaced the drain hose without removing the dishwasher from it's position. Due to this I removed the drain end with out being able to see the hose and put it back on by feel. Over all I was back up and running with in 30 minutes and everything has worked very well so far.

The old spring on the detergent dispenser box door failed and the dispenser door would not pop open at the right time in the wash cycle.

Ordering the new spring was easy on the website. Need dishwasher model number, stock number and serial number.

Hint - Order at least 2 springs! They are not expensive.

I followed the instructions in the video. I could get the spring on the spindle correctly but could not get the two spring prongs to catch to create spring tension on the door without using a thin knife blade to carefully push each prong to where it caught on the dispenser door.

I needed to slide the prongs slowly and carefully to get them to catch on the door. This distorted the spring. That's why you really need two springs. I then used needle nose pliers to pull the latching part of the spring to catch on the inner door. That distorts the spring, too.

So you really need two springs. One spring to learn how to do it and a second one to replace the one you distorted as you learned.

Take care

Followed the helpful instructional video that is included in the installation instructions here on this site. Had to drill out impeller to remove it due to 20 yr. old dishwasher w/ signs of hard water attack on the motor drive shaft. New part installation was quick, once the old impeller was completely removed and internal housing was cleaned.

Before installing new parts, make sure to flush out & clean internal pump housing to remove any loose debris and/or signs of rust, and carefully clean motor shaft & seal seat surface.

Also found heavy limescale buildup and soap residue on pump seal grommet & seal surface on the upper lip of the pump housing. Grommet is discontinued, but it cleaned up well along w/ seal surfaces, after soaking in white vinegar and employing a light scrub along the circumference of the seal (Not radially or perpendicular to the seal surface).

I ORDERED THE PART THAT WAS EASY BUT WHILE THE MACHINE WAS USED FOR HOW LONG I DON'T KNOW WITH OUT THE CAP IT GOT FILLED WITH FOOD AND JUNK. FIRST THING I HAD TO DO WAS EXAMIN THE DOOR AS TO HOW I COULD CLEAN THIS THING OUT. I REMOVED 6 SCREWS THAT HELD THE DOOR TOGETHER AND PULLED EASY CAUSE I DIDN'T KNOW WHAT I WAS GETTING INTO. NO PROBLEM THERE WAS NO ELECTRIC PLUGS HOOKED TO THE DOOR. I TOOK IT OUT SIDE AND STARTED USING VINIGAR AND POURING IT INTO THE HOLE AND SHAKING THEN TRYING TO GET IT BACK OUT. WELL THERE IS ONLY ONE POSITION THAT WILL LET THE VINEGAR BACK OUT. I HAD TO HOLD IT SIDEWAYS THEN TILT FORWARD AND IT WOULD RUN OUT AND BRING SOME JUNK WITH IT. THIS WAS A TIME CONSUMING PROCESS BEING YOU COULD NOT SEE INSIDE TO KNOW HOW MUCH JUNK WAS IN THERE. JUST POUR AND DUMP. AND DON'T FOR GET TO SHAKE TO LOOSEN ANY THING LEFT INSIDE.LOL I WAS VERY PROUD OF MYSELF NOT KNOWING FOR SURE IF I FIXED IT OR NOT BUT I TOOK A SHOT I HAD. I DID SOME SCRUBBING AND DEGREASING ON THE UNDERSIDE OF THE BOTTOM OF THE DOOR BEFORE I REASSEMBLED IT. THAT WAS EASY AND I CROSSED MY FINGERS ANY WAY. I GOT OUT MY NEW PART AND THE JET DRY I BOUGHT AND STATED TO FILL THE DISPENSER AND IT TOOK HALF THE BOTTLE.YEA !!! I PUT THE CAP ON AND COULDN'T WAIT TO DO A LOAD OF DISHES. EVERY THING IS LOOKING GOOD NOW. THANK YOU PART SELECT FOR MAKING GETTING THE PARTS I NEEDED SO EASY AND SHOWING DIAGRAMS SO I HAD THE RIGHT PART. I COULDN'T HAVE DONE IT WITH OUT YOU.

WATCHED THE VIDEO FOR 2 MINUTES. REPLACED THE 3 PARTS IN LESS THAN A MINUTE. THANKS FOR THE VIDEOS.

I ordered a dishwasher soap dispenser "lid assembly". When it arrived, it was not an assembly at all but only a lid. I had to reorder a pin and spring, When i finally had every thing, it was an easy repair.

Pulled the old gasket out with needle nose pliers, cleaned the slot for the gasket, installed the new gasket, needed no tools. This repair took 5 min.

after that every thing went very well

follow the video, no problem, however, its still not draining after the cycle is finish now I don't know what to do.

The old gasket around the door pulled out easily but was pretty nasty. While cleaning the channel out, kept finding more gunk that had built up. I decided to go ahead and take off the Inner Door. Used Torx driver to take off the screws. Found a tremendous amount of gunk built up. Was well worth taking the extra time to clean it all out. Replaced the Inner Door and put new gasket in channel. No more leaking!
