Mahlkönig Processor Board – K30
The Mahlkönig processor board 308389 for the K30. Original spare part, available in Bern and Zurich.
Mahlkönig describes it as the complete processor board for the K30 espresso grinders.
For the K30 in everyday use
The K30 is an espresso grinder. For espresso, the weight ratio counts, not the time. 1:2 is a good starting point. Every shot is still unique, because the bean, the humidity and you yourself change every day.

Mahlkönig assigns 308389 to the K30 espresso grinders without naming individual generations. For the K30 TWIN, Mahlkönig lists a separate display central unit. Send us the model and serial number at [email protected] and we will clarify the fit before you buy.
Who installs the part?
Mahlkönig intends repairs to be carried out by qualified technicians only. If you would like support with the installation, write to us at [email protected].
Can I see the product before buying?
You can see Mahlkönig grinders live in our showroom in Zurich Oerlikon (Hagenholzstrasse 50b). Whether the spare part is on site, we are happy to confirm by email in advance at [email protected].
Tip from the roastery: The K30 is built for espresso. The bean decides the taste in the cup. For most cups we recommend Cozy Chocolate and Nutty Delight: dense, round and chocolatey. For maximum body without acidity there is Very Nutty, and if you want to discover something fruity, you will find it in Wild Peach. That is our recommendation, one of many.
