Introduction
Go to step 1 ↓Since the hand mixer is no longer functioning, I disassembled it at a Repair Café. It was used too intensively and overheated. According to the website, spare parts from KitchenAid are not available for small kitchen appliances. I inquired via email and requested a replacement motor. I am still awaiting a response.
The device is not particularly easy to open. The installed electronics are unnecessary for a hand mixer. The motor is not protected against overheating.
I find the cost of approximately 90 Euros to be too high.
What you need
-
-
-
Use a small screwdriver to carefully pry off the chrome-plated cover.
-
Use a Phillips screwdriver to remove the two marked (recessed) screws.

There are two holes (c and n) under the silver sticker, indicated by the blue arrows. You can feel them. Push through these holes to push the tabs (yellow) underneath out of the way.
-
The bottom plate can then be lifted off from front to back. It must still be uncoupled at the back.
-
If you do not want to damage the sticker, you can also start prying off the cover from the back.
-
-
-
Unclip the cover from back to front.
-
Carefully detach the switch unit by twisting a narrow screwdriver at the connector. DO NOT pull on the cable!!!

-
-
The motor is held by the 3 screws in the housing.
-
Once the motor is removed and the button unit from the previous step has been disconnected, the PCB can simply be pulled out.

-
There is a white, elongated fuse at the corner of the PCB. Mine was blown. In the photo, you can see a temporary replacement fuse.

-
The carbon brushes are installed here. They are pressed against the motor armature by the copper spring. If the carbon brushes are worn out, alternatives of the same size could be installed.
-
When measuring with the multimeter, I measured different resistance values at different positions of the motor. I think that 160 ohms should be the normal value in every position. Please comment with any improvements.
-
Due to overloading, the motor overheated and some windings burned out. Afterwards, the fuse on the PCB tripped.

I found the RS9812SH motor online: http://www.cz-sanjet.com/products/Micro-...
