Periodic Maintenance - Synesso Espresso Machine Technical Manual

Proper and regularly scheduled cleaning and maintenance procedures are CRITICAL for
trouble free and optimum quality performance from your Synesso™ espresso machine.
Back-Flushing
On the current generation of Synesso™ machines, back-flushing can be programmed for
Auto-Flush activation. For Auto-Flush activation, please refer to the programming section of
the Owners Manual, page 21.
1.Replace the filter basket with the provided blind filter basket (a single solid basket
without holes) in one of the portafilters.
2.Engage the portafilter in one of the brew groups, turn the head to the BREW
position and leave it there for 10 seconds. Repeat several times (in Auto-Flush, the
machine will turn the group head on and off automatically; for manual back-flushing,
the operator must manually turn the group on for 10 seconds, then off for 10
seconds). This procedure should be performed on EACH brew group daily. This
process forces water through the inlet tube and drain system.
3.When using an approved espresso industry detergent during back-flushing,
follow the manufacturer's instructions. It is extremely important to thoroughly rinse
the blind filter basket and repeat back flushing several times with clean water to clear
the system of any detergent residue.
Cleaning
1.Clean the surface of the machine using a soft damp cloth. Avoid using abrasive
cleaners or cleansing pads. Take extra care on the mirror finish stainless steel
surfaces.
2.Make sure the steam wands and tips are free of milk built-up. It is always best to
clean the steam wand and tip after each use. Approved espresso industry cleaners
can be used to help dissolve milk built-up.
3.The drip tray, drip tray grates, cup tray grates and portafilters should be removed
and cleaned every day. If you clean the portafilters in the dishwasher, first remove
the filter baskets and insert springs before placing all items in the dishwasher.
Changing Portafilter Gaskets
Synesso™ uses an 8 mm gasket with grooves in the outside edge to help with ease of
installation and to allow trapped air and water to escape without contacting the coffee.
1.Remove the diffuser screen and screw
2.Use a small Awl or a screw driver to pry the old gasket out, then clean the area
thoroughly to remove any leftover gasket material
3.Install the new gasket, with bevel side up, using a small amount of food grade
grease or vegetable oil
4.Work your way around the gasket pushing it up into place with the rounded end of
a wrench.
5.Take the basket out of your portafilter and engage it to make the final "seat" of the
gasket. Pull hard to make sure there is no air trapped above the gasket.
6.Install the diffuser screen and screw.
