11. CLEANING
11.1. General cleaning
To ensure that the grinder functions properly, and produces the highest quality grind
possible, the parts that come into contact with coffee should cleaned periodically.
General Cleaning guidelines as follows:
•
Always turn the main power switch to the off position ( ).
•
Unplug the machine from the power source.
•
Do not submerge the grinder in water or use power washing devises.
11.2. Bean hopper cleaning
In order to properly clean the bean hopper (
), first empty out all remaining beans
and fragments.
To remove the hopper, first close the bean trap (
), and then loosen the hopper lock
screw ( ) and lift the hopper straight up.
Clean the hopper ( ) with a moist soft cloth or with a small amount of water and
soap to eliminate any oily residue from the beans.
Replace the bean hopper ( ) following the same steps as the removal process, but
in reverse.
11.3. Cleaning the coffee exit chute
It is very important to maintain the exit chute ( ) clean of coffee in order to assure
the consistency of the dosis and the continued functioning of the grinder.
A tubular chute brush should be used for this cleaning process. Simply inset the
brush up into the mouth of the exit chute ( ) (
Fig. 9
), carefully twisting the brush to
remove any remaining grounds in the chute.
Caution:
Do not force brush too high up the chute as there is a fragile rubber dosis
curtain at the upper end of the chute. Damage to the rubber curtain can result in less
precise dosing. Also, the dosis button (
) along with the upper and lower portafilter
holders ( ,
) should be wiped periodically to prevent build up of coffee grounds
and oils it is recommending to clean the out.
