Suddenly, your favorite German Clatronic bread machine (most likely made in China, as you will immediately see when disassembling it) has a problem: everything seems to work, but the dough does not mix. The cause is almost certainly a failure of the toothed transmission belt. Of course, before ordering a new belt on the Internet, it would be worthwhile to first make sure that the diagnosis is correct, that is, disassemble your oven and get to the transfer unit. However, here you will have to tinker a lot ...
Open the oven lid and remove the dough mixing paddles along with the baking dish. Then we unfasten the lid itself by squeezing out two slits on the lid fastening:

Now turn the stove upside down and unscrew 5 self-tapping screws (3 with a Phillips head and 2 with a DIN 546 head, which requires a special DIN 3115 screwdriver for slotted nuts):

Well, what these two screws with special heads are used for, I think there is no need to explain ...
If you cannot find such a screwdriver at hand, then it can be quickly made from a regular flat-blade screwdriver by sawing a small slot in the middle of the blade with a file.

Put the stove back on its feet and unscrew the screws inside the heating chamber. First, unscrew the top screw of the heating element,

and then 8 screws on the bottom of the chamber under the heating element. In this case, it would be good, for example, to use an angle screwdriver. However, with some care (so as not to damage the heating element itself), all this can be done with an ordinary screwdriver.

Now you need to unfasten the fasteners between the plastic bottom and the upper body of the stove in the places marked in the figure.

This can be done by gently pulling back on the plastic of the upper part of the case in the places of the fasteners (I recommend starting with the two rear latches). If you succeeded, then consider that half the job is done.
Now we need to disconnect the cable between the remote control on the top cover and the control board inside the case, which, again, for certain reasons, is very short and it's not easy to get to it.

Begin to gently lift the back of the plastic housing up (do not move the front!) Until there is sufficient access to the connector.

As a rule, both parts of the connector are filled with mastic, so you will have to carefully pick it out and only then disconnect the cable.
Finally, the upper part of the case can be removed and the insides of the stove appear in front of you.
It remains to unscrew 7 more self-tapping screws to get to the belt drive unit:

Finally, you are there:

Now you can definitely determine the degree of belt wear and the advisability of replacing it. It will not be difficult for you to change the belt and assemble the stove in the reverse order.

And finally, a couple more photos of the electric part of the bread maker
