Rinse Cycles
Brewer Rinse Cycle
1. Add VKI approved brewer cleaner to the brew chamber.
2. Press the "RINSE CYCLE" button on the control panel inside the front door.
To exit the rinse cycle if it was pressed accidentally, press the “PREVIOUS”
button on the front display.
3. Select the type of rinse cycle required. For a brewer rinse, press the "Coffee
Rinse" button on the front selection panel to begin the cycle.
To cancel the rinse cycle if it was pressed accidentally, switch OFF the
machine using the main power switch at the rear.
a) The piston will move to the top of the cylinder, water will pour in, and
the brewer will pause for about 5 minutes. During this time, the cleaner
breaks down all the oils and stains that have accumulated in the brewer.
b) After the 5 minutes have elapsed, the brewer will cycle, dumping the
cleaner into the waste container in the process. The brewer will then
automatically cycle water seven consecutive times to rinse the cleaner
from the brewer. After the rinse cycle is completed, the brewer will
stop and the coffee maker will automatically exit the rinse mode.
c) After the rinse cycle is complete, brew a few cups of coffee to re-
lubricate the brewer.
WARNING: Make sure the waste container is under the
brewer spout to catch the water coming from the brewer
(throughout the complete rinse cycle).

Maintenance
To keep the Eccellenza Express running efficiently and at peak performance, the
following maintenance procedures must be performed at their specified intervals. It
is recommended that equipment maintenance be scheduled at a time that would be
the least disruptive to your customers. Whenever possible, replace the components
requiring maintenance with new or refurbished ones, and then refurbish the older
components at your shop.
Daily
►Empty the Drip Tray – empty the contents of the drip tray and rinse the
tray and grill under clean running water.
►Empty the Waste Bin – empty the contents of the waste bin.
►Refill the Coffee Hoppers, Powder Hoppers – top off the coffee and
powder hoppers, and reset the product counters.
►Perform a Whipper Rinse Cycle – this should be done immediately after
refilling the powder hoppers to flush any product that may have fallen into
the whipper.
►Wipe Exterior and Countertop – using the clean towel, wipe any coffee
grounds and spills from the exterior of the machine and the countertop.
Weekly
►Clean the Grounds Tray and Floor Liner – empty and clean the
grounds tray located below the brewer. Remove and clean the floor liner
over the base of the machine.
►Wipe Interior Walls and Door - using a clean towel, wipe any coffee
grounds and spills from the interior of the machine and the front door.
►Perform a Brewer Quick Rinse Cycle – for the weekly Brewer Quick
Rinse cycle, it is not necessary to use any brewer cleaner. Simply flushing
the system with the hot water will help to keep it clean.
►Clean the Brew Chamber – the brew chamber should be removed and
thoroughly rinsed under warm running water.
►Clean the Grinder Spout – coffee grounds will accumulate in the grinder
spout opening due to static electricity and moisture from the brewer. The
grounds need to be removed or the grinder may jam. With the brew
chamber removed, use a plastic stir stick to delicately remove any coffee
accumulation from around the inner edge of the grinder spout.
WARNING:
Never use ammonia based cleaners on any machine
surface as the surface will become discolored and/or damaged
permanently. Use only mild cleaning products, such as dish soap.

Eccellenza Express – Service Manual

Monthly
►Perform a Brewer Rinse Cycle – the full Brewer Rinse cycle requires the
use of brewer cleaner to remove oils and stains from the brewer.
►Clean the Brewer Filter Screen – to minimize servicing time, replace
the filter screen with one that has already been cleaned, then clean the
stained filter screen at the shop and use it the next time a filter screen
replacement is required.
►Clean the Whipper System – disassemble the whipper system and clean
the components with hot water.
►Clean Hoses and Spouts – clean the exterior of all the product hoses
and spouts with a wet towel.
►Thoroughly Clean the Interior – clean the interior walls, base and
components with a clean wet towel.
Every 6-12 Months
►Inspect Electrical Wiring and Components - inspect all of the
equipment wiring, terminals, connectors and electrical components
(valves, motors, relays, element, etc.) for signs of wear, damage or
overheating at connection points. Replace them, if required.
►Inspect Water Hoses and Tubing - inspect all plumbing connections,
water hoses, tubing, clamps, fittings and water related components
(valves, water tank, etc.) for signs of wear or damage. Replace them, if
required.
►Clean the Coffee and Powder Hoppers – the hoppers should be
emptied of product and given a thorough cleaning to remove stains and
oils that may have accumulated inside them.
►Clean and/or Adjust the Grinder – remove the grinder cover and clean
the area around the grinding heads. Should the coffee being ground look
too coarse, the grinder may require a re-adjustment.
►Delime the Water Tank -to minimize servicing time, replace the water
tank with a tank that has already been delimed, then clean the removed
tank at the shop and use it the next time a tank replacement is required.
►Clean the Outlet Valves - to minimize servicing time, replace the outlet
valves with valves that have already been cleaned, then clean the removed
valves at the shop and use them the next time a valve replacement is
required.
►Replace the Water Filter – the water filter should be replaced at least
once a year, or when the water flow rate through the filter has decreased.
This is an indication that the filter is starting to clog.
Every 3 Years
