Clean group dispersion plate
The group dispersion set ensures uniform wetting of the coffee bed. When dirty, the wetting will
become less uniform. As the dispersion plate and base are made of plastic material, which is heat
neutral, no oils and fats will bake on easily and plate and base will remain clean for quite long.
Although the dispersion set is made of high quality plastic material (PEEK), it is slowly affected by the
aggressive cleaning powder such that it will need replacement eventually.
Materials needed
•
Short screw driver no.2
•
Group screen extractor (included in shipment, or back end of a fork or spoon)
•
Plastic brush (included in shipment, or toothbrush)
•
Coffee dissolving powder (included in shipment)
Procedure
1. Remove the group screen and group seal (see previous item).
2. Remove the two bolts from the plastic dispersion plate with a short screwdriver (see Figure 18),
the dispersion plate will fall out. Be careful with these screws, they have specific length to match
the thickness of the dispersion plate.
Caution!
The dispersion base remains in the group bottom. With the bolts removed, the connection between the
dispersion base and group bottom is fragile.
3. Clean the dispersion plate with a plastic brush. When necessary, put the dispersion plate in a
solution of coffee dissolving powder and warm water for about 5 minutes. Rinse under streaming
water.
Caution!
Do not scrub the dispersion plate with a metal brush or Scotch-pad as it will scratch easily and dirt
adheres more easily on a scratched surface.
4. When re-installing, tighten the bolts that hold the group dispersion plate with little torque.
5. Remount the group screen and group seal (see previous section).
