EVERY ONCE IN A WHILE, a new technology, an old problem and a big idea turn into an innovation.
Frequently Asked Questions
Motor does not start (Display is on and shows time/weight at zero)
- Adjustment not properly assembled: Check position of Adjustment (also see 5.1.4. Adjustment) - Hopper not fully secured: Remove and replace Hopper - Motor has overheated: Wait for the motor to cool down (also see 4.4. Operating time) - Setting: Selet a coarser setting - Make sure the coneholder is perfectly snapped in - etzMAX-medium: Use the optional cone that has a reduced intake of beans thus generating less heat - Check the time- / weight-settings: minimum 5g (weight-based) or 0.2 sec (time-based)
All LEDs (PRESET-buttons) on your weight-based etzMAX are lit with the Display showing 0.0 Your are in manual weighing mode. Press and hold STOP for at least 5 seconds to switch back to time- or weight-based mode (also see 4.6.4. Additional Features).
When pressing STOP for 5 seconds, your weight-based etzMAX switches from manual-weighing mode to time-based mode The system returns to the mode it was in before switching. Once you are back in time-based mode, press and hold STOP and 1 simultaneously (for 5 seconds) to switch to weight-based mode.
The grinding operation may be paused by pressing STOP but cannot be continued by pressing START To pause during grinding, press START (not STOP), to continue press START again.
The Maschine Safety Switch (Circuit Breaker) keeps triggering - Proceed as described in 6.2.3. Clearing Blockades and make sure the burrs are not blocked (by a foreign object / ground coffee) - Select coarser / higher setting (alse see 4.5. Adjustment) - Do not exceed the maxmimum permissible operating cycle / activation time per grind (also see 4.4. Operating time) - Keep the recommended breaks in between grinding operations - Use the optional cone for a slower intake of beans
Your weight-based etzMAX shows a different reading for a given output compared to what an auxiliary scale says
Make sure for both scales to be calibrated frequently (and/or after having been exposed to external interferences) as otherwise neither can be assumed as correct (also see 4.6.4. Additional Features: Scale Calibration).
Does the etzMAX-Updater APP work with Android? Although it would, at this point, we do not offer Updates via Android based on the fact that updating firmware via Android is challenging to the point of delivering negative user experiences.
To pull a good Espresso, you need to set the macro-adjust at 20 or higher Clean your grinder and check position of coneholder. Very important: Make sure it`s perfectly snapped in. Although some roasts do require high settings, most range from 3 to 8.
When to add (how many) shims and why?
In order to reduce the distance between cone and ring burr, the cone burr may be shimmed. Adding a shim unter the cone moves the grind range back thus compensating wear over the course of time (which might be sooner in case of very fine grinding). Shimming depends on use, coffee and preferences.
You encounter inconsistencies in flow rate (at the same amount of ground coffee) - Oily residues at the exit of the hopper may disturb the flow of beans. Make sure to clean your Hopper on a regular basis. - Small or mixed sized beans may hamper their steady intake around the safety-cone at the bottom of the Hopper thus causing distinctions in fineness.
Slower/longer flow rate (due to change in fineness) despite same setting Disassemble coneholder and thourougly clean grinding chamber and cone. When reassembling coneholder, make sure for it to be snapped in perfectly.
Faster/shorter flow rate (due to changed fineness) despite same setting Add one 0.2mm shim (delivery contents) underneath the cone. Watch the respecitive Video on our YouTube-channel (Adding shims).
Your etzMAX-medium keeps shutting down when using hard/light beans Use the optional cone (delivery contents) as the Standard Cone is optimized for medium-dark roasts. Watch the respective Video on our You-Tube-channel (Changing coneholder).
