CVA610 Coffee System
4.18.1

Water Intake

The Water Pump is responsible for taking in water from the Water
Tank. The bottom of the pump contains a safety valve. The valve is
designed to open should the system pressure exceed 16 bar (232
psi). A hose is connected to the valve to route the water away from
the components.
4.18.2

Water Path - Coffee

Water exiting the Water Pump is pumped under pressure through
the Flowmeter, through the Coffee / Hot Water Heater and through
the Heater Outlet Valve (Nipple) into the Brew Unit. Water passes
through the compressed coffee grounds and exits the Brew Unit as
coffee. The coffee then flows to the dispenser tubes on the front of
the appliance into the user cup.
4.18.3

Water Path - Hot water

Water exiting the Water Pump is pumped under pressure through
the Flowmeter, through the Coffee Heater and through the Hot
Water Valve and Hot Water Outlet.
4.18.4

Water Path - Steam

Water flows the same as the hot water system, except the water
exiting the Coffee / Hot Water Heater is routed via Steam Solenoid
into the Steam Heater. Steam exits the Steam Heater and exits via
the Steam Valve and Frothing Nozzle.
4.18.5

Steam Valve and Steam Valve Switch

The Steam Valve is a mechanical valve regulated via a knob on the
front of the appliance. As the knob is turned counterclockwise the
amount of steam exiting the valve increases.
The Steam Valve Switch is mounted to the Steam Valve Bracket.
When the Steam Valve is opened, the Steam Valve Switch is
actuated.
The switch is monitored by the Electronic and when actuated, the
Electronic energizes the Steam Solenoid (routing the exiting water
from the Coffee / Hot Water to the Steam Heater).
