4.18.1 Water Intake
The water pump takes in water from the water tank. The bottom of the pump
contains a safety valve which opens at approximately 16 bar (232 psi) system
pressure. If the pressure is too high and the safety valve opens, water is drained off
via a hose to the drip tray.
4.18.2 Water Path - Coffee
Water exiting the water pump is pumped under pressure through the flow meter,
through the coffee/hot-water heater and then through the water valve 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's cup.
