Dishes not rinsing well, particles left on dishes

  • Tools Required: Wrench (Adjustable)

As others have described, this replacement was very easy. The new spray arm is solid plastic instead of rubber (which had deteriorated and was the part that needed replacing). So it should last longer.

You have to keep and reuse the mounting bracket that attaches the spray arm to the upper rack, so don't throw that away!

The replacement was super-easy, and as others have commented, the dishes haven't been this clean for a long time. Well worth it.

Dishes wouldn't dry

I shut off the power to the dishwasher, then I removed the front panel under the door. On the right side just behind the electrical box there are two wires going up to the hi-limit thermostat, (you may need a small mirror to see it), remove one screw that is holding the thermostat bracket, unplug the wires from the old thermostat and install new one. Screw bracket and thermostat back to the underside of the dishwasher, reinstall the front panel, turn on the power, done.

Dishwasher not cleaning well... then leaking

  • Customer: Wesley from Lake Elmo, MN
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers

This gets a little lengthy... but it explains where Cascade Dishwashing Powder came up with its brand name - it's been a cascade project.
I started by replacing the Middle Wash Arm Tube as the old tube developed leaks. As others have stated this is a new design but directly replaceable and easy to do.
This didn't solve the cleaning issue so reading the experiences of others on this site realized I also had broken parts in the Upper Spray Arm Assembly and the Upper Wash assembly. I replaced these and the dishes were suddenly much, much cleaner. These were very easily replaced.
I did find that I did not need the Mount for the upper spray arm (PS402277) as a redesign of the Upper Spray Arm Mounting bracket no longer required it - the bracket simply clipped in -the diagram was out of date.
Everything seemed to go well for about 3 loads when the dishwasher started leaking heavily out of the bottom of the door. I then noticed that the lower Wash Arm Bearing Ring and the Seal, Lower Spray Arm had disintegrated so I replaced those but this didn't affect the leaking. Someone had stated that if the lower wash arm assembly had too much 'wobble' that it cause 'waves' that would leak out the front door... mine had some wobble so I added a nylon washer from Ace Hardware that reduced wobble but still leaked.
I then replaced the Door Seal Kit - this was by far the most difficult part as the door needed to be removed and it was somewhat difficult - and it seemed apparent after we had removed the door that these parts weren't the problem but we replaced them anyway.
Also, someone else had noted that they had to attach the door seal (this is NOT the gasket that goes around the door opening) with a sealant - I had the same problem; the original seal fit tightly with friction but the new replacement required an adhesive - I used silicone. Still leaked.
From here on I can't guaratee any useful information: I took the strainer screen out of the bottom of the dishwasher and found one slightly loose screw holding what I believe is the 'pump outlet' according to the diagram. I had also read that the water fill is controlled not by the float at the bottom of the washer but by the electronics and it was suggested that I disconnect the DW from the power to 'reset' the timer, this I did and hit the 'Cancel' cycle a couple of times to make sure that all programs were cancelled. Whether any of this made a difference I have no idea - except that the dishwasher suddenly stopped leaking and hasn't leaked a drop for at least 20 washes. So I don't know, for sure, why it leaked or how I fixed it, but it's working and washing great now - except the tines on the lower rack are beginning to rust out and breaking off. The rack is pretty expensive but so far I've saved a lot of money and my family thinks I'm a dishwasher genius.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

I removed inner face of door, cut wires leading to door switches, and then installed the new door switches and wire harness.

The machine just quit in the middle of a cycle and there were no lights on the control panel

There were eight of the star head screws to remove to take the front off the dishwasher, then just followed the instructions that came with the part, which was a thermal fuse and the new wiring that accompanied the fuse in the order. The hardest part was getting the old wire out of the harness with the other three, but once I figured that out just slid the new wire into place and made the connections. I reinserted the screws, turned the power on and knock on wood shes still working.

Kenmore UltraWash Dishwasher leaking

  • Customer: Andrew from Texarkana, TX

My wife noted wood floor bucking up around dishwasher - pulled dishwasher out from counter, tipped it on it's side, looked underneath, & noted slight corrosion on top of motor -

Took motor/pump assembly completely off of dishwasher (comes out from the bottom) by flipping four little plastic cams on motor to the side & then took pump apart (starting at top & working down) till I got to the impeller/motor shaft seal.

Found plastic impeller worn through into two pieces & little spring thingy under the grinder-upper thingy broken.

Ordered Drain & Wash Impeller kit - got it a few days later - installed (new motor shaft seal didn't seem to be quite the same as far as fit, so I didn't use it - just used the impeller & new spring thingy)

Put it all back together & runs fine - no more leaks - (now just have to figure out what to do about warped wood flooring - oh well, it's old & is probably time for whole new kitchen floor anyway)

Note: This particular Kenmore model made by Whirlpool - takes Whirlpool parts.

Note 2: Needed only screwdrivers to do this whole thing - would have been a really quick/easy repair if I had known what the problem was & how it all comes apart. took a little time to figure it out. (I am a rank amateur at dishwasher repair)

Top Spray Arm was hitting and would not rotate properly

The mounting bracket was broken.

The parts ordered were a direct match due to the fantastic pictures supplied on this site.
A dealer wanted to order it and then I would have had to drive and pick it up - no way.

partselect.com first time user - very easy.

broken wash impeller unit

I removed the rubber boot on the top of the water dispersal unit ( stainless steel wand ) by turning it counterclockwise and the wand came off with ease. I then removed the top unit under it by removing the 8 torx screws and removed it. Under the unit is a cover with 1 torx screw to be removed and removed the cover to access the unit. I was unable to loosen the 1/4" nut on the shaft as it was very tight so I had to remove the unit and lock the motor armature with a piece of wood and removed the bolt. Using the kit I purchased I installed the new parts as required and it works as good as new.

The whole problem started with the upper vent on the door being plugged up with a whole bunch of labels that had been washed off of a bunch of tin cans that were washed prior to recycling them. Te high water float was also gummed up for the same reason and overflowed on the floor, I pulled it up and out and cleaned it up also, it works as good as new.

Latch broke on dishwasher

  • Customer: Steven from Edmond, OK

Look at the exploded parts diagram, that parts select provides on their website.

You have to take off the nine star pointed screws. So you need a special screwdriver or I had a socket set of them and I used a ratchet to make it easier. I think there are nine of them around the base of the door. Then remove the door and set it on the counter. Flip it over and there is a small plastic cover that has to be removed from the back of it, and it is easily removed by gently pulling on it.

Now comes the difficult part. There is a locking piece on it that holds the latch onto the door by interlocking with a piece on the back side of the door. I took a pair of wire snips and just cut the old interlocking piece off. This way I didn't have to try and slide the two interlocking pieces apart.

When you go to put the new piece on before you interlock them make sure they are put on right. Specifically the latch is pointing the right way to seal the detergent door. Otherwise it can be a pain to separate the interlocking pieces again. (which is why I cut it off the old one).

Then you're done. Just put it all back together.

it would turn off and on mid-cycle and finally quit completely

I turned off the circuit. I removed the interior side of the door and then the plastic covering over the electrical wires and switches (I counterbalanced the door with a couple of half gallon juice containers). I removed the wires attached to the switch on the door handle and the door handle itself. The handle and switch parts disassembled and I replaced the switches (part of kit). I cut off the singed wire and the other three beyond the damaged portion and stripped the wires and connected the extensions (part of kit). I attached the new wires to the switches and closed up the interior door. Lastly, I turned the circuit breaker back on. All was well!

Dishwasher wouldn't clean - arms not spraying

Water was not being sprayed thru the arms. I opened the dishwasher, removed/unscrewed the spray arms and wash impeller (black plastic wheel that directs the water) and then noticed that the part below the wash impeller had broken into pieces. There was only a metal ring and it was supposed to have a spring attached to it. I replaced the ring/spring below the wash impeller using the part from the Drain and Wash impeller kit. The dishwasher works great now.

It was my first mechanical fix. Use the web to diagnose, find the specs of the appliance and use common sense and you can do it yourself too.

By the way, the parts from this site arrived the next day.

Dishwasher would not fill with water.

After doing some research in a repair book I decided to take a stab with a water inlet valve. With expedited shipping I ordered the part and within three days it was delivered. I installed it and the dishwasher seemed like it was trying to fill but still would not. After much cocnsternation I turned the water supply valve to the dishwasher a partial turn to close and I felt the water rush through the valve and the dishwasher then filled. Apparently the shut off valve must have been clogged plus it now leaked. I then replaced the shutoff valve and the copper pipe to the water inlet valve with flexible 3/8" tubing and the dishwasher thus far is running fine without leaks.
