Question about Bosch 700 Watts MUM6622 Universal Series Stand Mixer

1 Answer

"clunking sound" When the Bosch is turned on there is a clunking sound, about 3-4 per second. As the machine goes faster the sound also increases. Everything works but am afraid of doing damage if I continue to operate it. Thanks for your time, Mark

    As a follow up, I discovered that the large plastic worm gear has 3 teeth boken on it, hence the clunking sound.

    The question now is: Can the gear be replaced? If so how and where do I find parts?

    Thanks again,

    Mark

The plastic worm gear had teeth missing. I was able to order a complete drive unit ($85) from appliancepartspro.com

Bosch sds drill wont turn off


Sounds like you have burnt something out. It likely won't last long. Probably the motor is gone.It may burn out when you put it to real work. Good luck.

"Clunk" sound from mixer while running, now does not turn on at all.


You could take the brush covers off and pull the brushes out and look down the hole with a torch and see if you can see anything unusual down there. Also back cover off and look at the switch, wires and governor. If nothing is noted then you will be pulling it apart looking and testing until you find the fault. Making a clunk sound followed by death sounds to me like something has engaged with the motor armature and the majority of that is deep inside. Here in NZ those things have a 5 year guarantee, if wherever you are is close to still being in guarantee you should get it to a repair agent for repair without fiddling about.

Never used new bosch universal plus making bread started rattling sound


I do not know a lot about this machine. I am a DIY fix anything. It sounds like one of the mounting points on either the motor or the gearing gave way. Regardless it is new, send it back & have it fixed or replaced. Sorry, I know that is not what you wanted to hear, but is safest considering your investment.

My kitchenaid artisan mixer doesnt run fast enough


It may be seizing up the bush that your accessory drive runs in, if you can see grindings in the front by the square drive that is a sign. Here in NZ that bush is only available as part of that whole top cover/housing. The accessory drive gear will also need to be replaced.

Speeds don't increase after 6


The K45SS is very similar to the 5-qt. tilt-head Artisan Stand Mixer.
You need to adjust the mixer speeds. Obtain a copy of the K45SS Repair Part List from Kitchenaid.com. Remove the screw holding the End Cover and locate the three screws from the Control Plate. All three (2 top left and right, and 1 bottom) must all be adjusted. 1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

In middle of kneading dough, the machine stopped! I noticed that the gears that connect the bowl to the machine, stopped turning, when machine goes on, it makes a noise, but nothing turns.


Hi HENNY346. Your Bosch mixer is belt driven and from the description of your mixer’s symptoms I suspect that the drive belt has come loose or failed completely so it stopped driving the dough hook. You say that when you turn the mixer on, it makes a noise, which may be the motor running without any load, but your description of ‘noise’ is very vague.
The good news is that you should be able to diagnose and fix this quite easily (OK, maybe with a little effort) by yourself, if you are a DITY type person, feel adventurous, and your mixer is not under warranty.
Here are links to two online parts vendors for your Bosch mixer that also provide an exploded view diagram along with part names, numbers and prices. They are: Cook's Quarters and AppliancePartsPros.com It can be very gratifying to go “under the hood”, figure out what’s wrong and fix it yourself. Good luck , I hope this helps. Howard, Burke, VA

Noisy, high pitched whirring MUM6622UC/01 Bosch Universal Mixer


My wife's bosch mixer had a similar problem but it was a very loud grating problem. I talked to the bosch dealer in Utah, sorry, I've forgotten which one-- the one that does the repair. This is typically what happens: the seal on the blender wears out, which results in fluids from the blender dripping into the motor, onto the upper motor bearing. So, the upper bearing corrodes and is what is causing the bearing failure and the loud noise (needed hearing protection to operate it). I was lamenting the cost and time it would take to ship the mixer both directions (not actually that much compared to the price of the mixer), and he said he would sell me the bearing and the bottom replacement part of the blender that was leaking. So, I did the repair myself, but it took awhile, and I had to build a puller for the bearing to get it off the shaft, modifying a harbor freight gear puller. But it now is back to new. So, it was a success for me, but i would recommend anyone who isn't very mechanical to just send it off to Utah (again, I forgot the place, I think they talk about the shop in one of the other posts), and you will have a better than new machine.

Under a heavy load, the mixer began clunking once per revolution


Disassembly and inspection is the only way to verify what it is. It sounds like you are correct. I have bought parts very reasonably on line and repaired our K/A mixer. The better sites ( I think I used appliancerepair.com) have exploded diagrams. If you are tearing into yours, these are invaluable, and when you get to the broken part, you'll have a name for it.

Best regards, --W/D--
