Clean group dispersion plate
The group (lower) dispersion plate ensures uniform wetting of the coffee bed. When dirty, the wetting
will become less uniform. As the dispersion plate is made of plastic material, it is heat neutral such
that no oils and fats will bake on. The plate remains clean for quite long.
The dispersion plate is a wearing item. It is slowly affected by the aggressive cleaning powder and
needs replacement eventually. The dispersion base (or upper dispersion plate) wears at the same rate
(or even a little faster) as the dispersion plate and should be replaced together with the dispersion
plate. The new version of the dispersion set is made from (light brown) PEEK material that should
have a longer life-span than the (black) POM.
Materials needed
•
Short flat screw driver no.2
•
Group screen extractor (included in shipment, or back end of a fork or spoon)
•
Plastic brush (included in shipment)
•
Coffee dissolving powder (included in shipment)
Procedure
1. Remove group screen and group seal (see previous item).
2. Remove the two bolts from the plastic dispersion plate with a short screwdriver (see Figure 17),
the dispersion plate will fall out.
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, do not over-tighten the bolts that hold the group dispersion plate.
5. Remount group screen and group seal (see previous section).
