The Mahlkonig PEAK is designed for espresso grinding while the EK43 is more universal and can grind anything including filter coffee, espresso, and Turkish coffee. The PEAK has a broad range of espresso settings and features that make espresso grinding faster and more efficient without sacrificing quality. If you need a grinder to grind retail bags of coffee, drip coffee, pour-overs, and Chemex coffees, a retail grinder like the EK43 is ideal.
Your coffee grinder has been functioning perfectly for months, grinding your beans precisely, consistently and efficiently for well-balanced coffees or espressos. All of a sudden, it has stopped dead in its tracks. We often field the call where the customer reports that their grinder's motor is running, but it’s no longer dispensing any coffee into the burr chamber. Or their coffee beans aren’t feeding down into the burrs. The likely issue is that your grinder is jammed. Not to panic - this is actually a fairly common troubleshooting issue we run into.
