To carry out the 50,000 vend service, proceed as follows:
1. Disconnect the machine from the mains
electricity. Open the front door of the
machine.
2. Remove the coffee dispense pipe from the
brewer outlet.
Holding the unit as shown in the photograph,
lift the green lever (a) and carefully pull the
brewer unit out of the machine.
3. Carefully unclip the wiper arm from the
brewer unit and place to one side.
Remove the filter assembly from the brewer.
Holding the filter assembly as shown, turn
the green locking ring anti-clockwise to its
open position, indicated by the two arrows.
Carefully remove the old filter unit down and
out of the CoEx® brewer unit. Discard the
used filter unit.
4. Using a 3mm allen key, remove the bolt
securing the brewer drive coupling to the
input shaft. Pull the coupling off of the shaft
and place to one side.
Ensure that the captive lock nut is retained in
the drive coupling moulding.

unscrew and remove the three retaining
screws which secure the brewer unit

Carefully ease both the front and rear
brewer panels away from the central piston
