RUD8050SD0 Roper Dishwasher - Instructions

I first thought I may have a defective water feed tube that runs from the bottom of the dishwasher tub aolng the back to the top. This is what the top rack sprayer plugs into to get water.

This was easily replaced by uncliping the feed tube by the two clips, one on the top of the tub and one in the back. You then give the feed tube a twist clockwise about 45 degree (relative to the bottom of the dishwasher). This will remove the feed tube and bottom sprayer.

However, this didn't fix the issue.

I then replaced the pump/motor. This is done by uninstalling the dishwasher and flipping it onto it's back so you can look at the bottom of the dishwasher. There is an electrial connector on the right side that needs to be disconnected. The motor is help on by one bolt in the back and a socket wrench with extender will be needed to get to it. Once the bolt is removed, and motor needs to be twisted about 45 degress so it feels "loose". Then you need to pull straight down and the motor will come off.

Just reverse all the steps to install the new motor.

But that didn't fix the issue either.

Come to find out, the problem I was having was the grinder screen was so gummed up with paper, the grinder broke and water was not getting through the screen. Here is how you replace the grider (which was the true fix to the problem).

- Remove the feed tube like I listed above. You DO NOT need to uninstall your dishwasher.

- Use a Torx driver to remove the three visible bolts on the bottom of the washer tub.

- Pull up on the plastic piece you just removed the screws to remove it.

- Use a smaller sized Torx driver to remove the one screw from the Grinder plate. Once you have the screw off, use a pair of pliers to pull straight up on post sticking straight up on the grinder housing.

-You can now see the grinder. Pull the screen and grinder assembly out. If it is still intact, just clean it and replace it back into its groove. If it is in pieces, it is destroyed and buy a new one.

- Reverse all the steps to put the dish washer back together.

This screen that fits into the groove was jammed up with paper and was causing my my issues. Once I placed this the macine worked great.

I called an experienced plumber, who balanced and installed my new dishwasher properly, using the brackets I ordered from Parts Select, after an INEXPERIENCED plumber had tossed the factory-provided mounting brackets out with the shipping carton. Relief!

I initially thought the pump assembly was dying (or was damaged by a piece of glass or something that had gotten into the pump. I priced the parts and decided I wasn't sure the unit was worth it. But the dishwasher was also not cleaning well, and was leave soap on the dishes. Turned out the water inlet valve was intermittently failing to open. Using the troubleshooting guide (both downloadable and inside the bottom panel) was no help. I just checked and saw that there was power going to the valve when it did not open: diagnosis made. Step 1: turn off water to dishwasher. Step two: remove bottom panel. Step 3, place towels under dishwasher. Step 4, disconnect water line from elbow screwed into inlet valve. Step 5: remove inlet valve screw with nut driver and slide valve sideways and back to remove. Step 6: slide clamp on hose to dishwasher away from valve using pliers. Some work involve with sliding hose off the valve (careful, the hose is accordioned plastic) Step 7: remove elbow from inlet valve (this required a visegrip to hold the narrow nut surface on the valve and a wrench to turn the elbow). Step 8: apply Teflon tape to elbow and screw into new inlet valve. Step 9: install hose to dishwasher and return clamp to hold hose in place. Step 10: reinstall valve by placing tongues into grooves and sliding to the left, reinstall screw. Step 11: tighten elbow with wrench, now that valve is held in place. Step 12: reinstall water line. Step 13: turn on supply line and check for leaks

After replacing the thermal fuse 5 times i noticed the new packaging came with a terminal block on then fuse harness. PLEASE USE THIS. It is a must, it supposedly is acting as some type of heat sink or something for added protection. Used the unit on all cycles now and works great. Just follow fuse instructions precisely. Hope it helps.

I switched off power to the dishwasher and unscrewed the front panel from the inside sides. Then, carefully removed the front by lifting up and off. I disconnected the signal wire by unclipping it from the detergent dispenser; it clipped in like a phone jack. Unscrewed the frame holding in the dispenser, then popped out the old dispenser, popped in the new one, screwed on the frame, hooked the signal back in. Replaced the front, screwed it in, turned on power and ran a small quick wash to make sure it was working properly. It was!

1. Put a towel over the bottom of the machine. (In case you drop the screw... duh!)

2. Remove the top screw.

3. Replace the snap pin (pointy end DOWN.)

4. Snap the spinner in place.

5. Replace the screw. (Or go to the hardware store to replace the screw you dropped into the bottom of the dishwasher. Dashitall!)

First let me tell you I am not a "handyman". I am a 50 year old housewife who was determined not to shell out $$$ if I could help it. I researched on the internet what could be the problem...it was more than likely the chopper assembly. I found a youtube video that showed how to get to the chopper assembly. So I removed the racks by dislodging the end clips. Next I took the bottom tub sprayer off by holding the middle with my fingers and turning the blade counter clockwise. Next, I unscrewed the line that ran in the back and up to the top sprayer (I only removed the one screw so I could slide it to the right slightly so I could remove it from the connector at the bottom and it revealed four screws that needed to come out of the mesh cover. After removing that there is one more screw that comes out of the shroud that covers the chopper assembly. I cleaned the area removed the chopper assembly (totally gunked up) and replaced it with the new one I purchased here...(lightening fast shipping btw!!...Yea! for PartsSelect.com....you guys rock!) I checked for gunk in the rubber valve assembly, super easy to remove/replace. Vacuumed standing water with my shop vac to get any errant noodles and food bits and reassembled all of the housing and lines in reverse order. Before I ran my dishwasher I put some clean water in the bottom...just poured about 32 oz in. Whether you need to or not....I don't know but figured it wouldn't hurt. IT WORKED LIKE A CHAMP! Super clean dishes again!! I felt so empowered and the whole thing cost me less than 20 bucks! Listen ladies....and men....this is super easy....If I can do it....any one can!

This was an easy repair. The leak was around the solenoid of the inlet valve and thus the assembly needed replacement. Turn off the water. Take the screws that secure it to the cabinet out. Pull the dishwasher out where you can tip it on its side. (you might get someone to help you hold it tipped. Disconnect the water line (copper) and the inlet hose (just clipped on)and the electric connection.
Take one screw out that holds the valve assembly in place and remove the valve assembly.
Put the new assembly in as the reverse procedure. Make sure to use plumbing tape on the threads to the copper water connection so that you wont have a drip leak when its tightened.

My dishwasher motor was getting very noisy lately and finally died altogether. (the fwd bearing and seals had worn out. There was a small pile of what looked like white sand under the motor from the wear) I removed the dishwasher from the counter after turning off the power at the breaker box. I then turned the dishwasher on its side. The pump motor is removed by first removing the electrical connector, then loosening the retaining bolt and twisting the motor counterclockwise about a quarter turn. The gasket required a little force to become unseated from the housing but not to bad. Wiggle and pull! Be sure to take a look at the alignment at this point to facilitate reinstallation.To install the new motor, align the mark on the impeller(small delta) with the mark on the motor. Insert Motor into housing and turn clockwise one quarter turn till retaining bolt hole is aligned. Install retaining bolt. Be sure to note the position of the stainless steel screen where you insert the motor. Place it back in position before installing the pump if it is disturbed. I lubed the oring with vaseline prior to install also. The new oring was diffrent and did not feel very tight when i installed , but there were no leaks and the dishwasher is running like new. Partselect had the part at my door the next day with no upgrade in shipping charges and I will use them in the future. This forum helped me choose them and made the task easier to do. Hope this helps you as well.

As I pulled out the old rubber gasket I noticed there was a flat side and a curved side, this is how the new one must go. When I put in the new gasket in I just made sure the flat side (faced out) and it really was very simple. It just fits inside a grove, very easy to install. I compared the to parts (old and new) they were exactly the same shape and length.
I was very impressed with the web site navigation and layout. I was able to zoom in on pictures of the part and there were exact measurements of dimensions.

Very easy to install the new B Metal Fuse. Removed torx head screws holding the outer door panel on the dish washer. Removed the fuse and two wires connected to the fuse. Inserted the new fuse in the holder and plugged the two wire connectors back
on. Installed the outer door panel back on, turned the breaker back and the machine powered back up. Very easy install and saved a service call. Total repair cost $24

unscrewed dishwasher from cabinet ...,moved out slightly....while door closed ...reached with long nosed pliers door spring pulled forward...and allowing white plastic part that fits through sleeve and fit new sleeve over it...pulled spring attaching white plastic part and pushed unit back to cabinet and replaced screws DONE.

Checked grinder and cleaned it several times, adjusted blades. Dishes would be clean for approx. 6 cycles, then would not clean. Placed dishwasher on its front and removed the motor. Removed grinder and impeller which I found to be worn so that the blades would not turn on the grinder which caused it to collect food particles. The impeller locks in easily.

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.
