An automatic beverage brewing apparatus (20) having a brew chamber assembly (24) with a brew chamber (45), an inlet (43), an outlet (41), and a controllable water distribution system (30) coupled to the brew chamber (45) for controllably introducing brew water and flush water to the brew chamber (45). A filter assembly (52) is disposed in the brew chamber (45) and an opening is formed through the filter assembly (52) for communicating with the brew chamber outlet (41). The water distribution system (30) includes a flush water dispenser positioned centrally in the brew chamber (45). A spool (58) is disposed in the brew chamber (45) and is operatively associated with a device (28) for controllably moving the spool (58) in axial and rotary directions. The spool (58) includes a head (122), a base (125), and a necked portion (127) extending between the head (122) and the base (125). The dimensions of the head (122), base (125) and necked portion (127) allow the filter assembly (52) to be installed and removed over the head (122) and base (125). The spool (58) is disposed in the brew chamber (45) with the head (122) controllably movable in the inlet (43) and the base (125) controllably movable in the outlet (41) for controllably opening and plugging the inlet (43) and outlet (41). A port (176) is coupled to the flush water dispenser and extends through the exterior surface of the spool (58). A discharge line (551 from the brew chamber (45) has a controllable discharge valve (55a) to direct flow from the brew chamber (45) through a dispensing line (55b), a waste line (55c), or to prevent flow through either line (55b,55c). Water may be controllably accumulated in the brew chamber (45) by controlling the discharge valve (55) to prevent flow through either line (55b,55c). The discharge valve (55a) blocks the discharge line (55) to retain water in the brew chamber (45) to float spent brewing substance (53a) off of filter material (164) in the filter assembly (S2).
