front modules
§The X54 offers four predefined recipes that can be adjusted to user requirements

the espresso machine fits tightly into the portafilter module.
§Fasten the screw and remove the filter holder
§Place the portafilter module back into the X54 grinder and fasten it securely
§The portafilter holder should now fit tightly and allow for “hands free” grinding
What is the capacity of the hopper of the X54?
§Appr. 500g / 1.1lbs
What is the weight of the X54?
§Net weight: appr. 5kg / 11 lbs
What is the grind speed of the X54?
§Appr. 1 g/s (finest grinding for espresso)
§Appr. 2.5-2.8 g/s (coarse grinding)
Which factors does the grind speed of the X54 depend on?
§Origin and type of coffee (e.g. arabica, robusta, etc. ),
§Size and hardness of beans, degree of roasting and cooling method after roasting (i.e. moisture content of the bean)
§Cleaning status of grinder

Where is the X54’s ON/OFF switch?
§The X54 ON/OFF switch is located at the back of the grinder where the power cable exits the housing
§The X54 takes approximately 3-5 seconds to fully boot
The display of my X54 is on, the motor does not start. What can I do?
§If the Error message E001 is displayed the motor does not start because the bean hopper is not mounted correctly
§The hopper has to click-in completely for the motor to start operating. To mount correctly, push down the bean hopper and push through the stainless steel bean slider
until the hopper is locked into place
§When new, the hopper fixation will be a bit tight, which will wear down after some repetitions
Which repairs may I carry out without loosing warranty?
§As described in the user manual, the grind chamber may be opened for cleaning or checking for foreign objects
IMPORTANT: Any warranty claim is void in any of the following cases:
1. The grinder casing was removed
2. Electronic components were changed or tampered with
3. The grinder was obviously manipulated or changed
4. Improper use (other materials than coffee were ground).
How and how often should I clean my grinder?
§Your grinder should be cleaned approx. once a week. Cleaning intervals are highly dependent on intensity of use, type of beans and grinding degree
§We recommend GRINDZ to clean your grinder –please follow the user manual for specific directions
How do I empty my grinder to switch coffee beans
§Pull out the bean hopper slider until the indication marking is visible –“closing” the hopper while leaving it firmly attached. Now operate the grinder normally until all
residual beans in the grinder neck have been consumed. You can now pull out the bean hopper slider completely to remove the hopper and switch beans.

§An exchange due to wear and tear is easily possible but not expected to be necessary
Can I grind turkish fine with my X54?
§The X54 is designed to grind fine espresso all the way up to coarse coffee for French press
§Even at the finest setting the discs will not be able to grind very fine, flour-like coffee powder needed for Turkish preparation
§Turkish fine grinding requires demanding conditions of discs, disc casing and motor made from high precision and stable materials
Can I change the grind adjustment without starting the grinder?
