How to repair a Bosch dishwasher that squeaks and doesn't clean

- This is a fastener by fastener description of how I successfully replaced the impeller on the circulation pump of a Bosch Dishwasher, Model #SHU53AD5UC14. The machine was making a grinding squealing sound and water circulation was poor. Evidently this is a fairly common weakness of the older Bosch design, and the new impeller seems more robust. Although it may sound like the motor needs to be replaced, this repair is much less expensive. If you have the exact same model, the part number is 167085.
Any dishwasher repair should start with basics of cleaning the drain filter, and inspecting the water supply hose and the drain hose. For a good review of how to inspect and clean the drain filter, go here

Scroll through the discussion and find links to two separate pdf files which describe this in detail. The newer document (titled DishwasherTraining bosch.pdf) posted later in the discussion on page 9 was more relevant to my 2002 vintage dishwasher.
This is a complex repair, so you should not attempt it yourself unless you have some experience and confidence with appliance repair. You will need a T20 Torx driver if you plan to attempt this. Note that it would be possible to do much more harm than good if you make an unsuccessful attempt to repair your dishwasher. Also note that there are many different models of Bosch dishwasher and each is repaired differently. Be prepared for it to be significantly more difficult than it appears in the video, and always be wary for your safety. Be absolutely sure that the power is off before attempting any appliance repair.
This is a demonstration of amateur effort, posted for entertainment purposes, and it is not an instructional or diagnostic guide. For safety, do not attempt this without professional advice. Any misadventure resulting from your attempt to repair your appliance is your responsibility.
Thanks for the easy to follow step-by-step directions. This just saved me buying a new dishwasher! To get the impeller back in place I found it easier to put the unit on its side.
Something that is very complicated and you dive into it unsure of what lies ahead is absolutely perfect for video. I tore down the head of my engine and it would have been impossible without video to put it back together in the correct sequence. A little $90 pocket camcorder saved my bacon. It's the way of future!
Thank you for uploading this video, I just repaired my dishwasher using your technique. In my case the pump seal had failed and salts, etc escaped into the motor bearings which led to the motor practically seizing up. So as well as replacing the items that come with the kit I also cleaned & lubricated the motor bearings. The hardest part was rotating the pump to release it, it was well seized!
Hey there Cave dweller, this is a little nugget of gold from your past.... I feel my identical Bosch is slooowly developing the same symptoms. I've had my machine apart to clean and service the drain assembly. This was an excellent video, of which I will follow in your handy steps.
Aside from also owning a sailboat, I wish you had a Mercedes E320.lol! thanks again
Till now I've just taken photos during disassembly but you've convinced me of the added value of shooting a video.
Great Job!! I just fixed mine. A slghtly different model but the same process. Your tips were invaluable (the clip on the pump and how to remove it with a twist, and how to release the wire clips). I would add to not even try to twist the pump out until you have lifted it off the frame, the extra room is required.
My pump housing (the white piece with the clips) was pretty chewed up as well so I just ordered a new one and will be repeating the process next week. The 2nd time is always easier.
Thank you for a very informative video, and for the terrific and detailed presentation. I repaired an impeller of another dishwasher earlier generation dishwasher before, but the Bosch is another animal, and you revealed many details I would not have otherwise known. You saved me much time.
Fantastic video! Liked how you mentioned that Bosch changed the impeller and the issues with the old poorly designed one. Successfully changed it out and the dishwasher is working great.
Thanks for the feedback, it's nice to hear from people who tried this themselves.
Thanks for the feedback, Steve. I'm glad it helped and I'm glad you were able to find the video -- that's sometimes the hardest part.
This video was a huge help. 15 year old DW back in business. Thanks!
Ha ha, it's been ten years since I made this video. The dishwasher shown in the video is still going strong! Thanks for the feedback.
Hi, thank you very much for your video! I have just repaired our Whirlpool dishwasher, as the design varies very little! After looking at your video I was much more comfortable doing this job even in our kitchen!
The details and camera work are very good and now I shall attempt to repair my Bosch dishwasher.
Thank you, I hope it works for you. My dishwasher is still going strong
today. The main tricky part is fitting the parts together in such a
tight space. Once you know how those plastic parts snap together, it's
fairly straight forward. Good luck!
I appreciate the feedback. As you know, the big challenge to for those who need the info is to find it on a Google search. Glad it helped.
In this case it was looped behind the cabinets so that wasn't an option, but that kind of thinking is often gold. You're right, not much room there. It helps to dial the feet up and down depending on what you are trying to do. Thanks for your comment!
From 13:13 onwards: setting the pump back in place. This is indeed very difficult, heavy. My pump had some chalk on the metal. It took me hours to get it back, I almost decided to buy a new dishwasher, but then I used some silicone spray on the metal pump surrounding and the opposite plastic part. Then with a little pressure it succeeded. Note : before you do put the pump back on, make sure this "plastic tab" is not clicked into position, it should be in the opened position. Then fit the motor on the plastic where the notch (12:58) is. Then I used some pressure and turned the motor anti-clockwise and it snapped, luckily. Without the silicone spray I had to use so much pressure which didn't work because of the thickness of the black rubber ring. In my case: the impeller was already replaced 1 year ago. This time the start condensator on the motor needed replacement, I took of the pump like in the video. But afterwards I think I didn't need at all to get the pump out :-). So first 2 dishwasher runs today went like crazy again, life restoring to normal in the kitchen. Good video!!! 2012 haha.....Today 2021, my dishwasher is from 2004 still running after 5 repairs: dirty watermatrix, faulty microswitch, loose solderconnection on the door-PCB because of the heat, impeller, condensator. I wonder what will be next :-)
Thanks for your helpful input, Cotty! I did consider that, and if I had not discovered the manufacturer's document (link appended) showing how they recommend doing the task I might have tried that. Inverting water filled cavities could soak dry electrical devices and possibly cause more headaches. Also, I'm not sure the AC wires were long enough to permit me to invert the dishwasher, and so I might have had to disconnect the main wiring. That said, sometimes techs find better ways to do things.
Thanks for the response. I wish I had more clearly illustrated how to remove the motor, which is tricky. But I think I did get across the important point about how it has to rotate on removal and installation.
Now in 2023 this identical dishwasher was making a similar noise. Following my video here I tore it down to find the impeller had slipped free, and the lip of the plastic housing itself had eroded away. This time I am skeptical that replacing only the impeller would solve the problem, difficulty finding parts notwithstanding. So, after a glance at my wife, who was praying that my repair would fail, we finally cut this workhorse free, saving the motor for future considerations. I was a little shocked at how a decade of life has spun so much more silver in my hair, ha ha.
Thanks for stopping by. As you know I give each of your interesting automotive uploads a look, every week. It seems like a friendly shop to work in.
Hi, Caroline. That price seems high, mine was ~$45, but shipping may be an issue from North America. I don't know what the above website would do for shipping to Norway, and it may take a while to be sent over while you wash dishes in the sink. You might ask around for a better price. Those two plastic parts came apart in my hand, and the bent plastic bits made the diagnosis obvious. The new part was fused together as one. Are you sure of your diagnosis? You might look for other problems.
It was fun to learn how this device works, and overall I thought the engineering was pretty slick. Thanks for your comment!
Just watched you video regarding the change of the washmotor impellor kit. Boy you make it look hard its a simple task. lay the dishwasher on its back and remove the base and take of the dishwasher sump its alot easier that way to change the motor impellor kind regards Cotty
Thanks for adding to the thread here. Getting the motor out was the hardest part for me, as well.
Thanks for making this video. I know it’s quite old now but a lot of it is still useful for newer models. Cheers.
That's red tape labels the wrench I use for my Dodge Ram oil drain plug. It's marginally easier than fiddling with a dog bone wrench. One day the US will entirely switch over, hopefully in my lifetime. Thanks for your comment!
I see that you have marked your SAE wrenches with red tape. I've done the same thing only I use red for my metrics. I think this makes finding the correct type, either SAE or metric, easier.
Very good video, have have saved me time and frustration. BTW, I did not have a replacement part so I tried to glue it back together with two part epoxy. Works so far!
Well just finished performing your procedure on our 16 year old Bosch. I found the motor easy to get out and everything went well until the whole pump motor chassis slipped out of the pan....I analyzed and found getting the chassis back into the pan easy. So I proceeded. All ended up excellent. Thanks so much for posting this video... I like your process over the Repair Clinic's process. No need to remove the whole bottom of the washer. The 2x4 worked perfect!
I might add that the reason ours failed is a piece of dental floss made it's way into the impeller/motor shaft and caused the impeller to drag. The reason this happened is the wife would not secure the drain filter properly thus particles would slip past the filter and the filter pan.... Gotta make sure that the filter is secure and holding the filter pan down properly!
I you were nearby I would supply you with a case of your favorite beer!

Hey, thank you for your followup. I'm sure others here will find this
helpful, and it's a great reminder why that drain has to be properly
fitted.

Heh xddd
😅😆
It's bee a while since I did this. Do you have the same model of dishwasher? Can you remind me what the plastic connection you are referring to? One way to explain it to me is to refer to a specific time of the video where I am holding it in my hand, by typing in the time, for example 5:46, which automatically links to the part when the reader clicks.... I used searspartsdirectdotcom for the part I needed.
Thanks for your informative video. I have posted the noise my dishwasher makes, and I was wondering if you could tell me if it is the same issue: Needing the replacement of the impeller: The video is titled "Strange noise from the dishwasher!" on RUclips.
I'm talking about what seems to me a turning with difficulty problem, from minute 1:22 of the video. Thanks a lot. Do appreciate your insight!
Thanks for this video, it helped me to repair the pump. Now I have to remount, but I don't remember where was positioned the black plastic support that you show in the frame 14:15, in a dish togheter with some screws. I know that is an old video, but can you help me?
Gee, this is a walk back in time. I had a vague memory of that black plastic clip, and on review of the video I think I am showing it come off starting at 2:49. It is there as a safety clip to prevent the waste water hose from coming off. Am I describing the part you have?
@@spelunkerd Mate, you are great! Thanks to you and to your memory, now the puzzle is complete!
Hi! Im fixing our dishwasher,but can't seem to get the "plastic connection" off..I tried with the same tool,but it seems to be stuck...and were did you order the new piece?:) thanks! greetings from Caroline in Norway:)
enjoy your teaching skills very much... (just a comment) saw other videos where they lay the dishwasher on its back to remove the circulation motor...hope you do more appliance repair in the future...
Thanks, Pei! Yes, I hope to make more videos soon, but usually it's because something isn't working. So, maybe not (grin).
Yes, when the device is dry and unattached to the wall it would be possible to flip it over and that might make the repair easier. I followed a step by step description of this repair which was published by the manufacturer, and they did it the way I showed, including using that wooden spacer to lift the chassis up to get more room. I like the way that worked, and in my case I think the risk of spilling water on the electrical parts would be lower. If I had to do it over again I would do it the same way as I showed. Thank you again for your thoughtful remark.
Thanks for the feedback.
Yeah, I'm not sure why they designed it the way they did. Sometimes it's a factor of using a weak link to protect more vulnerable parts.... Thanks for watching!
I use different colored magic markers (learned this from an electrician) to mark both the wire & its terminal which makes reassembly almost idiot-proof. I used to use self-adhesive labels but they can sometimes fall off.
Good idea! I do the same with automotive tubing but I've never done that with wire.
Do you think a soldering iron could re-melt the two pieces back together. On the pin pieces? Great video
rmariu It seems to be a manufacturing design defect that was improved with new parts. I guess you could fiddle with old parts, but given the work needed to get to the part and the inexpensive nature of the replacement, I would just put in a new one. Any time you add metal to a spinning shaft, you need to be sure it remains balanced or it will put strain on bearings and maybe make noise. Good luck!
Your videos are very good. Thank you for making them.
Thanks for quick reply:)!The model is SGU44E28SK and your holding the "plastic connection" at 11:07. I found the part,but they want for about 126$,.. How much did you pay for the spareparts? I feel this is very expensive,but I lack experience so I don't know what these things normally cost... other than that,I have followed every step and I found your video very helpfull:) thanks!
I'm glad it helped, thanks for the feedback.
THIS VIDEO HELPED MY BROTHER OUT GREATLY!!
MIght be easier to disconnect the drain line under the sink instead of at the appliance. I like how little space they leave you under the kick panel, don't you?
Thank you, I agree. Whenever I need to do a task like this, I search for answers on video first.
How did you know the diagnostics "code"? Is that in the manual, and does it decipher the problem?
Thanks!
One of the annoying things about the RUclips format is the video description is partially hidden under a tab titled 'show more', above. Click that tab, the full video description will appear. There I show a link to a pdf file that describes this repair in detail, made by the company for professional repair technicians. You'll see that to show the codes, you click three buttons all at the same time, and the appliance goes into a self diagnostic cycle, taking about 20 minutes. At the end, a code may flash on the front display, and you can use that code to help diagnose the problem. Sometimes diagnostic codes are useless, or even misleading, but it's showing what the problem is from the microprocessor's perspective. In my case it didn't help at all.
Thanks, Harry.
I just epoxy glued the propeller and reused the gaskets to perform the repair. I am not sure that it is good idea. I will see if it last and let you know the results after months... My dishwasher is 20 years old.
Thanks for the contribution to the thread. Was it hard to find a replacement impeller?
@@spelunkerdMy propeller was still good. I just glued it using epoxy. I did not replace any part. My dishwasher is a DLX model from Bosch.
Thank you.
Thanks! Great step-by-step.
Great video, thank you for your time!
Ha ha! Do you know my wife? I think I remember her saying the same thing. Thanks for the comment.
Good stuff as always.
Looks like they need to do some research on automotive clutches. Those pins would last a long longer if they were at least metal. Get a billet aluminum one made and never worry about it again. :P
Ha ha, another funny comment, thank you! Yeah, happiness is a working dishwasher, only appreciated when you go for a few days without.
Thank you for a great video. helped me allot fixing my Bosch dishwasher.
Thank you for the feedback!
Well done !! Getting caught up on that honeydolist I see.
smashing job, but you didnt check the timing or clean the sparkplugs lol :-)
They love making daft designs where you have to have 3 hands to do the job :-)
Clean plates anyway :-)
Another very funny comment, ha ha. Thanks, Brian.
Do you ever get the feeling that an achilles heel is purposely designed into almost every product?
Squeaky, but not squeaky clean. lol
