Introduction

Go to step 1

If these microswitches on the drive do not work precisely, the machine will not work properly and the drive may be damaged. Replacing the Cherry DX41 microswitches is not very difficult.

Note: you can also open the drive without unscrewing it completely. Then skip the corresponding steps.

These instructions may also help with other Siemens/Bosch models and with coffee makers from Nivona, Melitta, and Miele—they have a very similar design.
