My cofee machine Krups EA8250 diagnosed error 01 - means problem with watter distributor. After spending 2 day with disassembling, cleaning and assembling of whole watter distribution system I found out there is problem with gears beneath motor not moving as one of the gears had some teeth broken - see photos. 

If there is sound of something is stucked, it could mean same problem.

For repair I have 3D modeled and printed new spur gear on photo on my own.

3D model is available in .step as it works with Prusaslicer and can be easily modified.

Printed from PETG works perfectly till now, but nylon could be better solution- 0.15 layer height.

In case you need different one you can calculate module of the gear from outer diameter and number of teeth.

I also found another spur gear for Krups machines on thingeverse, see link below:
