GRAN BARISTO 05 TROUBLESHOOTING
Detailed description of the diagnosis menu
1. Product counters
"Product counters" represents the total number of deliveries performed by the machine for
each product from the production.
2. Error counters
"Error counters" displays the total number of errors "out of service" (fail) occurred in the system
(see "Errors log"), and allows you to reset the drive (see "Errors reset").
The maximum number of "fail" count is 20.
The submenu "Errors log" is available only if there is at least one error and, if so, submit the fol-
lowing information:
Error code: is the numerical code for the type of fail has occurred in the system. For example,
"Error code E01" is the error with index 1 and is equivalent to the Grinder blocked.
Error index: represents the numeric position of the error in the internal list.
The maximum number of elements in the list is 20: the list is handled in a circular fashion, that
is, the data in the fi rst position is always the last error that occurred in order of time (eg 01/07
means that you are reading the most recent error on a total of 7 errors).
Error text: is the text description of the type of error that occurred in the system.
For example: "Grinder blocked."
The cancellation of the error list by "Errors reset", as it deletes all information relating thereto,
also prevents access to the menu under "Errors log".
List of possible errors of "out of service":
Grinder blocked (E01): occurs if the grinder is to have the mills blocked.
In this case, the machine stops the instant the user asks for the machine to dispense a drink
made of coffee (just coffee beans).
Brewing unit blocked work (E03): occurs when the brew unit can not move from location to
location work home.
Brewing unit blocked home (E04): occurs when the brew unit can not move from the home
position to the work position.
Water circuit interrupted (E05): occurs when the fl ow meter is faulty, disconnected or does
not occur passage of water. In these cases, since the machine fails to correctly read the pulses
of water, enters alarm condition "CHARGING CIRCUIT" in the moment in which the user asks to
dispense a product:
if the "charging circuit" the machine supply fails block.This total.
DC Valve short circuit (E06): occurs when one of the valves of the fl ute is short-circuited.
This problem may occur during the delivery of a product based on milk.
