Having problems steaming Milk hot?
Use Milk flow restrictor Click Here to order to steam Milk Hotter
Eliminate Milk Carafe. They are expensive and need frequent refilling, intense cleaning
and replacement of damaged or lost rubber connectors. Use of Milk flow restrictor with
15" Silicone tube Order part # 26151-S15
The restrictor is used on frothers that draw milk from a Milk container. Cannot be used
for straight Pannarello frothers.
Extensive Calcium deposits are seen in almost every espresso machine
we open for repairs.
Filter cartridges are preventative, expensive & ineffective as descaler.
The Brita filter installed on the kitchen faucet works better.
Calcium sediment inside the machine causes the following problems:
(1) reduces internal flow of water with full or partial clogging.
(2) generates back pressure in the Hydraulic system & causes internal leaks.
(3) reduces pump pressure, reduced flow of coffee & internal leakage reduces
programmed coffee in the cup (4) Error codes "Fill water" or Ventilate will display.
This will shut the machine down & force expensive repairs.
Descaling is best done manually, every two or three months.
Order Best descaler (#DSC-6) from our online store for effective & authentic Descaling

2.2. Specifi cation for the measurement of the coffee products temperature.
The temper
ature is infl uenced by the fl ow from the dispenser and stratifi
cation of temperatures in
the glass. In order to consider these phenomena and to introduce measures that allow comparisons in controlled conditions, below guidelines must be followed:
Conditions:
a) Water temperature in tank: 23°C (+/-2°C).
b) It must be used a plastic cup (see picture N°1).
c) It must be used a thermocouple thermometer (e.g. type K - see picture N°2).
d) The coffee machine is tested without any change of parameters or calibrations, which may
affect the temperature of products, so the measurement of temperature must be done with
machine in default factory setting.
Procedure:
1. The temperature must be measured in the cup, immediately after dispensing. Cup has to be
placed on a non-metal surface using a thermocouple thermometer.
2. The temperature in the cup is measured by immersing the probe of the thermometer up to
touch the bottom.The probe then must be moved in a circular motion for 5/6 rotations. At the
of the rotations, stop in the center of the cup.
3. The highest temperature measured during the rotations is the value we are searching for, and
that must be reported;
4. Test measurement: from end of dispensing to the end of rotations must be completed within 12
seconds.
Limits of acceptability
The acceptance limits are divided by features and products and are the following:
Espresso Coffee Italy Q.ty 25/40 gr.
Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C
Coffee Q.ty 70/120 gr.
Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C
