Dispensing Hot Water - Keurig B3000 Service Manual

5. Dispensing Hot Water - To deliver hot water only, the system is closed, vent valve [J] is de-
energized, and the hot water dispense valve [OO] is opened. Through a combination of the force of
gravity and a pressure boost from the brew pump, water now flows from the lower hot water tank cover
thru a silicone tube, the hot water dispense valve [OO], a silicone o-ring, seal cover, and the hot water
trough. The water does not take the same path as in the coffee brewing process because the boost in
pressure form the brew pump [G] is lower than the cracking pressure of the brew path check valve [M].
