WU300 Dishwasher - Instructions

After nearly 20 years of use (and no service) my Maytag dishwasher stopped getting dishes clean. I called Maytag and they made me an appointment with a nearby service center. The Maytag person also suggested I do a run with an open container in the dishwasher filled with a couple of cups of white vinegar – since that dissolves the white scale buildup from hard water. That helped a lot. Yay Maytag!

I had 5 days to wait for service, so I started Googling. I found very negative reviews of my local service center, but I also learned that I could buy a replacement detergent dispenser online and I found excellent simple instructions for installing it. It arrived in two days and I installed it. The hardest part was removing the front panel of the dishwasher to get access and supporting it while taking out the last couple of screws – then holding it in place afterwards while putting the screws back in. I recommend having a second pair of hands!

I also realized that the two rotating spray arms (at the bottom and at the top) weren’t rotating! They’re easy to remove (just unscrew the center component), and I found that many of the holes were clogged – including all the ones pointing sideways that make them spin. I had to force water inwards through the holes to dislodge the debris, then I filled the arms with water through the center hole and sloshed it around to clear things out. That worked. I put it back together – and the dishwasher is now as good as new!

For good measure I took the cover off the strainer in the bottom to clean it, but surprisingly the strainer was almost completely clean.

I cancelled the service appointment, of course. I’m sure I saved a lot of $$$.

I had read that recently mandated reformulation of dishwasher detergent with lower phosphate content makes it less effective – but I’m not seeing that: a little simple maintenance and my dishes are 100% squeaky clean again!

Put spring in plastic bushing, snapped into door arm and hooked opposite end of spring in first hole. Repeated process on opposite side of door. Did the above without moving the dishwasher from installed position.

The repair was very simple and covered completely in the instructions that came with the springs. However, I am writing this not so much to describe the repair but to give unsolicited praise to PartSelect. I pretty much only purchase online, so I spend a lot of time on web sites. This was probably the best shopping experience I have ever had (Google and Google Tool Bar were also involved). I found the site using Google, but then found my part in about one minute with the great diagrams. Checkout was incredibly easy and my parts arrived two days later and the door was fixed 30 minutes after that. I'm a customer for life!

Replaced door gasget took 5 minutes tops. Ran cycle and still had leak. Called local repair person. After thoroughly checking out the dishwasher and running soapless cycle determined problem to be soap build up over time. He ran a commercial cleaner through a complete pots and pan cycle. No more suds and no more leak repair complete. Did not actually need door gagset but it was super easy to change and delivery service was great.

Replaced the impeller using the kit. Had to brake the impeller since it was stocked due to rust.

I watched the video link sent in an email and followed exactly what they did in the video. I removed the star head screws holding the door liner in place. Then removed the protective cover on the inside. I disengaged the component holding the latch in place. I replace the component that holds the latch in place and then snapped the new latch in place. I turned the dishwasher dial until the prongs were fully retracted. I replace the protective cover and then put the door cover back in place. I initially only placed the left bottom star head screw until I was sure that the latch was going to release. I tested that it was working properly by slowly turning the dial on the dishwasher control. Once I knew it was working I replaced the rest of the screws.

removed old check valve from bottom of dishwasher and replaced with new one. I used channel locks to do this, disconnect hoses and screw out check valve, and put back in opposite order, make sure the dishwasher is empty of water or have a plastic bowl or such to catch water. Take off two front covers on bottom of dishwasher to access check valve ,white with hose attached.

I removed access panle then disconected the wires, water inlet line, and water outlet line from the valve. then took the two screws that held the valve in place off and removed the old valve and replaced with the new. Its that easy. I had one problem that did'nt want to stop haunting me...water leaks at the conections. Tip: don't put access panle on untill sure there are no leaks. You might notice I had an earlier article with a float switch. It turns out that that was not the problem. This water valve was, and it works great again. Not bad for 24yrs old(yes, the dishwasher).

had to pull the unit out abour 6" and simly replaced the springs - it was easy

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.

turn off power to unit
open the front to remove washer arm and nut
turn unit on its front
looseing the pump assembly from connections
and motor
replaced parts reversed order of assembly
done
cost was much cheaper than other places
one place wanted $160.00 another
place wanted $130.00
with your parts i fixed it for $61.00 that included two day shipping
thanks i will shop here again

We took the rollers off the old one (new ones came with the dishrack also) and put them on the dishrack (they snapped on). There was also an extra piece that we figured out how to put on. Then slid it in place and it was fine.

First, I checked the ripped box for damage to the dishrack. Fortunately, there was none. Then I looked for the instruction booklet. Unfortunately, there was none. And the parts bag was ripped and I did not know what was supposed to be in it. So, I rechecked the photo of the dishrack on the website and found that either parts were missing or the dishrack was different than illistrated. After a few moments of thought, I realized the latter was the case. I then figured I would have to use some deep thought to do the installation since neither the missing instruction booklet nor the unzoomable photo would help. So, I pulled out the tall thin thingamabob from the old dishrack and put it in the new one though it did not secure as tightly. Then I put the wheel units on just like the old one. What I could not immediately figure out was where the collapsible rack row was mounted. I eventually realized that the rod went into a hole in the wheel units and the latch mounted above one unit. I still have no idea where the two other tan clips go. Though the dishrack is different and thus requires different science to fill it, it appears to do the job.

Thanks for asking.

By the way, it was not blue.

I layed the bottom rack upside down on the counter. Removed the old wheel sets and the new ones just snapped into position. I think the rack rolls better now than it ever did with the original equipment. I'm glad we purchase the Tandem Rack Rollers instead of a new dishwasher, it works great.

Unscrewed the nozzle cap, screwed in the new nozzle cap. What a snap! Sure beats a $75.00 service call and a parts bill that would be double what I paid!
