Key Operator

The bistro! Key Operator is authorized to perform the following service tasks of service level 1: • Perform customer check-up• Change descaling filter• Descaling

The Key Operator also does repairs.

Service maintenance 1 and service maintenance 2 should only be done by service personnel specially trained for this machine.

To perform the tasks listed above the Key Operator has access to the service routines, the component test as well as to the counters “total number of brewings” and “operating time”, to the “maintenance counters” (restricted to customer check-up) and the “descaling filter” in the machine data.

This access is protected by a special PIN (Key Operator).

The maintenance messages “customer check-up”, “service maintenance 1”, “service maintenance 2” and “revision” are displayed. They can be set with “KonfigTool”.Unlike in the presto, no service messages for individual components such as grinders, portioners and mixer are displayed.

Customer check-up see Maintenance schedules chapter Change of descaling filter see menu service date Descaling see service routines menu

Menu PIN Key Operator





Descaling filter

The authorization is intended for customers who can change the descaling filter themselves. In this case the care menu features an item “counter reset”.

Customer check-up

This is set to “yes” if the machine is supposed to display a request for performing customer check-up after 15,000 brewings. The menu item for resetting the counter is then included in the care menu.

Customer check-up comprises the changing of foamer and mixer cup with the respective nozzles and hoses.

Service Routines





4.3 Valves submenuAdditional information in the tests:• Condition of water pressure switch• Condition of steam pressure switch• Maximum current consumption of the valve(s)

The brewer must be functioning during brewing-valve test as the brewer accepts the brewing water during the test and discharges it afterwards.

4.4 Milk unit submenuAdditional information in the tests:• Condition of water pressure switch• Condition of steam pressure switch• Maximum current consumption of the valve(s)

4.5 Steam boiler submenuAdditional information in the tests:• Steam pressure: Ok = boiler pressure reached• Electrodes: Indicates if the LW and PW electrodes have

contact or not

During the PW/LW electrode test the current capacitative value is displayed

5 Service routines software

Service routines overview

5.1 First run upThe software is restarted, a “reset event” is entered into the laptop ring memory (see Reset reasons chapter). The mandatory cleaning operation is reset as if a cleaning cycle had just been performed.A cleaning cycle currently in progress can be interrupted.

If a cleaning cycle was interrupted appropriate measures must be taken to ensure that no residues of cleaning-agents remain in the machine. The cleaning-cycle should therefore be run again.

The reset in the setting menu is treated in the same manner by the software; the customer reset, however, does not reset the mandatory cleaning operation.





5.2 Brewer calibration• After entering factory data • After replacing brewing unit• After replacing brewing unit motor• After replacing brewing cylinder • After each brewer maintenance The standard value of the brewing unit must be re-checked so that the “empty” messages are issued correctly.

The calibration must be performed with the brewing unit completely clean and empty.

5.3 Portioner calibrationThe calibration must be done so that the amount of coffee powder can be correctly set in grams in the settings menu. The alignment value also affects the software-technical empty message. After determining the alignment value, the grinder correction is reset to 100 %.

5.4 Replacing control unit backup battery after F157

When error message F 157 occurs, the battery must be replaced.

Follow the instructions on the display: � Save all data in the service memory � Disconnect the machine from the mains � Replace battery � Reconnect the machine to the mains

All data are automatically reloaded into the customer memory.

until a slight contact of the running grinder disks is audible. � Fit grinding-disk scale � Turn grinding-disks 4 scale steps backwards (1 scale step

equals 0.05 mm) which gives the basic clearance of 0.2 mm � Fit disc 33.1324.7000 in such a way that its cam prevents

further screwing down. � Set scale with the number 0 towards the upper marking and

stick it on.

Setting standard grinding-discs (“Rossi” 33.0693.000:Basic settings for left grinder (espresso): 1.5Basic setting right grinder (Café creme): 3.5Basic setting for 1 grinder only: 2.6

Settings for Ditting grinding-disks 33 .9462.6000: Grinding degree is 1 degree finer than standard.

8.2 Adjusting pressure reducer � Turn off external water tap � Open stopcock on water filter, depressurize and close cock

again. � Open front panel, remove front protective cover. � Remove blind nipple from the plug-in connector of the

espresso pump � Connect adjusting tool 33.2730.0000, to the plug-in

connection of the espresso pump. Hold loose end into the drip tray.

� Turn on external water-tap again. (Attention, water will run out of the setting-tool).

� Adjust pressure reducer by turning the set-screw to 0,23 +/- 0,01 MPa (2,3 +/- 0,1 bar) flowing pressure.

� Static pressure can be measured with the blind nipple of the setting-tool, Setpoint 0,26 ± 0,036 MPa (2,36 ± 0,36 bar) turn of external water-tap.
