Pressure gauges

All the Elektra coffee machines
are provided with a dual pressure
gauge to show pump pressure
(left side) and boiler pressure
(right). The pump pressure is the
water pressure at the pump outlet,

When the machine is making coffee,
the pump turns on to force water
through the grounds. The pump
pressure increases to 8 bar (green
region on left side scale). The boiler
pressure will drop slightly, but
should remain at around 1 bar.

Automatic and The Elektra coffee machines are
available in semi-automatic and

automatic.
In an Automatic machine the
water flow is measured by flow
meters in the machine. This
means the barista simply presses
a button to make a particular cof-
fee drink, with the machine turn-
ing off the flow automatically
when exactly the right amount of
water has been dispensed into the
cup (or cups for a two cup handle).
The amount of water dispensed is
not affected by the density of the
coffee grounds, so you are always
assured of the right level. The finer
the coffee grounds, the longer it

will take for the water to be
dispensed. The amount of water
for each type of coffee drink is
factory set, and can only be
changed by a technician.
A Semi-automatic machine has
either pushbuttons or levers to
control the group head water flow
for making coffee. The levers on a
semiautomatic machine operate
internal switches, so flicking a
lever has the same action as
pressing a button. The water flow
is not measured by the machine,
so the barista has to turn off the
flow when the cup (or cups) con-
tains the right level of extracted
coffee.
