2.1.2 Water Path – Coffee
The highlighted path in Figure 051-2 details the flow of water in the coffee- and
espresso-making process. Water flows from the water tank (3), through the flow meter
(4), and into the coffee/hot-water pump (5), where it is pumped out through the
coffee/hot-water heater (10). From there it flows through the pressure relief valve (12),
then the brew unit filled with coffee (15) and finally through the dispenser into the
cup(s). The coffee puck drops into the waste container, and the residual water runs
via the drain valve (13) into the drip tray (17).

2.1.3 Water Path – Hot Water
The highlighted path in Figure 051-3 details the flow of water for hot-water production.
When "hot water" is selected, water is drawn from the water tank (3), through the flow
meter (4), and into the coffee/hot-water pump (5), where it is pumped out through the
coffee/hot-water heater (10). The hot-water solenoid (9) opens the hot-water path, and
the hot water runs through the hot-water dispenser into the cup.
