Section 5 - Service Keypad Functions
Genesis machines are fitted with a service keypad (a)
mounted on the rear of the door. This keypad contains the
Engineers Program entry key and also allows an
engineer/operator to carry out specific functions during
routine cleaning and maintenance.
N.B. During certain operations e.g. View Counters it is
necessary for the engineer to utilise the selection keypad
and LCD mounted on the front of the door to access data.
Please refer to Section 3 - Programming Mode for details of selection keypad layout
and functions.
When the safety key is inserted into the door switch and the machine is switched on,
the service keypad allows the engineer to carry out the following functions:
5.1 Switch 1 - Program Entry
This switch allows the engineer to access the Engineers Program (Section 4, page 16).
5.2 Switch 2 - Brewer Open (Freshbrew Models)
1. This switch operates the brewer fitted to freshbrew machines and allows the
brewer chamber(s) to be removed for cleaning or maintenance.
2. When the Brewer Open switch (2) is pressed and released, the brewer will
index to its fully open position and stop.The engineer can then safely lift the latch,
remove the chambers and carry cleaning or maintenance. Pressing and releasing
the switch again will cause the brewer chamber(s) assembly to return to its closed
position.
5.3 Switch 3 - Rinse/Flush
1. The flush sequence operates automatically and rinses the mixing bowls. Before
the sequence begins, the system waits until the water in the boiler is at the
correct temperature determined by the thermistor.
2. In order to guarantee the highest standards of cleanliness, the boiler fill valve is
disabled, ensuring that the water used in the sequence is delivered at the optimum
temperature to kill any micro-organisms. Each hot water valve and the
corresponding whipper is switched on in sequence for a pre-set flush time.
3. Once the flush cycle is complete, the boiler refills and when the water is at the
correct temperature, the machine returns to standby mode, ready to vend.
