2.5.3 General Information - Service Mode 1 Service mode 1 can be used to advance through the individual program steps of a selected program. Steps should be advanced rapidly with a maximum of 2 seconds of pause. If a step is not advanced, the selected program is continued normally from the step reached. The parameters affecting the fault-monitoring system also apply during the service mode. If, e.g., a heating step is accessed, then a fault is registered if sufficient water has not previously entered the cabinet (water level is checked via the heating level switch). After the start of a program, the current program position is shown via the program sequence indicator. The wash block display is suppressed and the actual temperature is shown normally when selected via the top program function button. TheDryingfunction can be selected or deselected via thecbutton before the start of a program, if it is normally available for the program being checked. A cleaning program selected in service mode 1 can be quit or interrupted as follows: –Open the door The door lock is not active in service mode 1. The cleaning program is interrupted and, when the door is closed again, the program continues in service mode 1 from the step reached. –Shut off the machine The cleaning program is interrupted and, when power is restored, the program continues in service mode 1 from the step reached. –Turn the program selector switch to the 12 o'clock setting The selected cleaning program is interrupted or the program currently selected but not started is canceled. The electronic is still in service mode 1. A different program can now be selected and started. –Quit service mode 1 Turn the program selector switch to the 12 o'clock setting and shut off the machine. 2.5.4 General Information - Service Mode 2 x Note Before making settings in service mode 2 the fault memory should be checked. If service mode 2 is quit with saving, then all entries in the fault memory are deleted. Service mode 2 can be quit without saving any parameter changes that may have been made by interrupting the power supply in some way (e.g., by opening the door). Service mode 2 is divided into 6 or 7 service levels (S 21toS 26orS 27, depending on model). Printer interface data can only be modified or displayed if a Descriptive Technical Documentation 070-6 DTD no. 62-7881 This information should not be duplicated or passed on without Miele approval.

printer interface is present and activated. When stepping back and forth through the various programming levels the active programming level is onlydisplayed, e.g.,S 23, when the program selector switch is turned to the 12 o'clock setting. Settings in service mode 2 always apply for all cleaning programs, except when impermissible settings have been made in individual cleaning programs. Service mode 2 can be quit without saving any parameter changes that may have been made by interrupting the power supply, e.g., by opening the door. 2.6 Program Summaries 2.6.1 Program Summary (P 06) - G 7882 x Program Block G 7882 Wash Programs1) SPECIAL 93°C-10 minSPECIAL AN 93°C-10 minvario TD vario TD AN VR 1[—] [—][10 L cold water] — [1 min] [60 s drainage] VR 2[—] [—]—[15.5 L cold water] [1 min] [90 s drainage] HR 1[10.5 L cold water] [16 L cold water]10.5 L cold water 16 L cold water [DOS 1 / 40°C] [DOS 1 / 40°C]DOS 1 / 40°C DOS 1 / 40°C [[93°C / 10 min]] [[93°C / 10 min]]55°C / 5 min 55°C / 5 min [60 s drainage] [90 s drainage] 60 s drainage 90 s drainage HR 2[—] [—]— — CH-DESIN[—] [—] [—] [—] SP 1— — — — SP 29 L cold water 14.5 L cold water 9 L cold water 14.5 L cold water DOS 3 immediately DOS 3 immediately DOS 3 immediately DOS 3 immediately 1 min 1 min 1 min 1 min 60 s drainage 90 s drainage 60 s drainage 90 s drainage SP 35 L cold water —5 L cold water 10.5 L cold water 1 min 1 min 1 min 60 s drainage 60 s drainage 90 s drainage SP 4— — — — NS 1[—] [—]— — NS 2[9.5 L demineralized water][15 L demineralized water]9.5 L demineralized water15 L demineralized water [DOS 2 / T2] [DOS 2 / T2]DOS 2 / T2 DOS 2 / T2 [75°C / 3 min] [75°C / 3 min]93°C / 5 min 83°C / 10 min [60 s drainage] [90 s drainage]60 s drainage 90 s drainage Table 5:G 7882 (P 06) Program Summary, Part 1 1)The program blocks that appear in bold within the square brackets are fixed and cannot be activated or deactivated, except for the type of water intake.

2.7 Software Index Versions, Program Sequence Plans 2.7.1 List of Software Index Versions and Modifications –Software index P 00 (start of pilot series) –Software index P 01 (ID 488) –Software index P 02 (ID 524) –Software index P 03 (ID 560) Introduction of service mode function S 27. –Software index P 04 (ID 585) 1. Parameter adjustment of all "vario TD”programs. The washing parameters of programs "vario TD", "vario TD AN" and "B" (vario TD NR of G 7882/CD) increased from 113°F (45°C), 3 minutes, to 131°F (55°C), 5 minutes. 2. Additional rinse in program SPECIAL 93°C 10 min. The rinse SP 3 with reduced water quantity has been activated for program SPECIAL 93°C 10 min in order to prevent carryover of salt from a reactivation cycle (especially important in the dental field). The change applies to all machines that use this program. 3. Modification of water intake for vario TD. In order to ensure better cleaning performance, the second water intake for "vario TD" programs is also carried out with cold water. This makes no difference in models G 7881, G 7882 and G 7883, as they do not have a hot-water connection. This change means that in G 7882 and G 7883 CD models, the second water intake is now with cold water. 4. Drainage times - Steam condenser (DHK). The drainage cycle of the aerosol-injection steam condenser has been modified in order to remove water that has entered from the wash process before closing the steam condenser vent opening. 5. Introduction of function to block STOP. Service mode level S 26 has introduced a function at selector switch setting 2 which prevents program interruption by selecting STOP. However, if a fault occurs during a program that leads to program interruption, the STOP setting for fault acknowledgement is still required. 6. After ventilating a dispenser with pump, a "0" is no longer displayed but "dox", where the x represents dispenser number 1, 3 or 4. –Software index P 05 (ID 860) Descriptive Technical Documentation DTD no. 62-7881 070-11 18.09.2013, US_am This information should not be duplicated or passed on without Miele approval.

1. If an aerosol-injection steam condenser is installed, the steam condenser (DHK) pause can also be activated without drying in order to, e.g., reduce the level of steam escaping with high-temperature programs. 2. Depending on model (with/without steam condenser (DHK) and with/ without drying unit (TA)), service mode 2 (level S 26 - Function 3) offers various options as follows: 1. S 26 - "-": DHK (aerosol-injection steam condenser) not installed 2. S 26 - 30: Without additional steam condenser (DHK) pause 3. S 26 - 31: With additional steam condenser (DHK) pause when drying is not active (applicable to models with/without drying unit (TA)) 4. S 26 - 32: With additional steam condenser (DHK) pause when drying is active (applicable only to models without drying unit (TA)) 3. The G 7882 CD is supplied as standard without rinse aid dispensing. If a new electronic module is supplied as a spare part, it must be programmed to activate rinse aid dispensing if this had previously been set. 4. G 7883 and G 7883 CD–The dispensing options in program block CHEM-DESIN have been extended. The order of the setting figures has been adjusted. x Functions (E 03-4x)Machine Model G 7883 / 83 CD G 7882 / 82 CD No dispensing 40 40 Dispensing via DOS 1 immediately 41— Dispensing via DOS 1 from 40°C 42— Dispensing via DOS 2 immediately 43— Dispensing via DOS 2 from 40°C 44— Dispensing via DOS 3 immediately 45— Dispensing via DOS 3 from 40°C 46— Dispensing via DOS 4 immediately—47 (was 41) Dispensing via DOS 4 from 40°C—48 (was 42) Table 9:Extended Dispensing Options 5. Reduction of cleaning temperature level E 01- Function 10. Previously the reduction of the maximum temperature from 93°C to 90°C was only carried out correctly in program block HR1. As in this block the parameters of SPECIAL program are also defined; duration here was also correctly automatically extended from 10 minutes to 25 minutes. All other temperatures > 90°C then also had to be reduced manually. This is no longer necessary with the modified software. 6. Time basis for ventilation functions (programming mode) modified. The time basis for automatic ventilation functions has been modified from 1.1 seconds to 1 second.

7. If a reduced water quantity is programmed in program blocks VR2, SP1 or SP2, then heating should not take place in these blocks because the wash pressure is not sufficiently constant and this can lead to the registration of a fault (F 3EorF 27). The interdependence has been adjusted. 8. With the electronic module EGPL 081 P 05 (ID 860), a diagnostic support file (DUD) for the Miele diagnostic utility (MDU) has been created for the first time. 9. In the programming mode, the range of dispensing options in program block CHEM-DESIN has only been extended for the G 7883 and G 7883 CD. However, values for the other machines have been modified. In service mode level S 26, two new functions have been added under positions 3 and 4. The program summary of G 7882 CD has changed with regard to dispensed agent utilization in the final rinse stage. –Software index P 06 (ID 1180) 1. Clock setting in customer programming mode. Sometimes the service department is needed to make the changeover from summer time to winter time and vice versa. In order to offer the operator the possibility to set the clock time himself, programming mode level E 34 has been created with which the time and date output at the printer interface can be set. The functionality is equivalent to the clock setting function at service mode S 22 (functions 3 to 7). However, settings will only be accepted if the interface has been activated in service mode S 21. Several seconds may elapse before the current data is output via the interface. Default values are displayed until the current data can be shown. 2. In order to be able to follow the actual program structure on a printout, program block names where no special parameters (such as dispensing or wash temperature) are set are now also printed. 3. Machine number index. With the introduction of the new control, the packaging of new machines is printed with the number 062 (clock setting for operator). 4. Drain pump pause. To improve drainage, 2.2 seconds after the drain pump has started, it is stopped for 2.2 seconds and then operated normally until the drainage time has elapsed. This action improves pump ventilation. 5. I 2C bus fault. Under certain circumstances, communication problems of the I 2C bus might not be registered. This only affects communication with the additional module EZL 031/081 and is indicated with fault codeF 11. If Descriptive Technical Documentation DTD no. 62-7881 070-13 18.09.2013, US_am This information should not be duplicated or passed on without Miele approval. All rights reserved.
this fault is registered when an interface is active, the fault codeF 13is always correctly generated. The modified software ensures that this communication problem is correctly identified. 6. A new diagnostic support file (DUD) for the Miele diagnostic utility (MDU) has been created for electronic module EGPL 081 P 06 (ID 1180). 7. With the introduction of the new control, the machine technical documentation is no longer located behind the cover plate under the door, but is now included with the machine accessory pack which also includes the operating instructions. –Software index P 07 (ID 33960) 1. Hot-air drying filter time reset. In machines with software index P 06 with a drying unit (TA), both filters are always active. As new G 7891-93 models have only one fine filter, the use of a single filter is taken into consideration. This modification has no effect on previous machine versions. 2. Creation of a batch number. The protocol (report) function has been extended to include the creation of a batch number and the printer interface has been modified accordingly. The control transmits a 2-digit version number, which can be created via the diagnostic support file (DUD) to the interface, and the interface creates a 6-digit sequential batch number. The version number is required in order to be able to differentiate between new and old protocols should the printer interface be replaced because a new interface always starts with the number 000001. With version number 00, the creation of a batch number is suppressed. In old control versions up to P 06, a batch number is not created, even with a new interface. 3. Door lock. The routine to lock the door has been modified. From software index P 07, the door is locked immediately after a program has started. 4. Dispenser relay control with EZQ 081. Due to a change in legal requirements, all disinfectors with the control family MC Novo must be fitted with a dispenser relay control by the end of 2007. This is to be certain that continuous dispensing can be definitely avoided. In order to ensure backwards compatibility with older controls, service mode S 26 has been extended with function 5. 5. Fault codes with EZQ 081 (print texts of the serial interfaces). The printed texts have been extended to include the dispenser relay control functions. The following fault codes have been established which will only be evaluated with active dispenser relay control (S 26 - 51): F 31: Dispenser relay control cannot be monitored or is defective (dispenser relay control). Descriptive Technical Documentation 070-14 DTD no. 62-7881 This information should not be duplicated or passed on without Miele approval. All rights reserved. 18.09.2013, US_am
F 32: Faulty activation, dispenser relay on EGPL or EZL stuck (dispensing relay). F 33: Maximum permitted activation time exceeded (dispensing time). 6. Control modifications, corrections and extensions. The automatic ventilation times stored in the electronic module have been adjusted for the internal dispenser pump DOS 3. When an electronic module is reset, the dispenser control settings (E 02 - Functions 9 - 11) are no longer overwritten. This means that now when an old electronic module is replaced with a new one and the flow control is deactivated at the same time, this will not be reactivated after a reset. 7. Creation of new diagnostic support file (DUD). A new diagnostic support file (DUD) for the Miele diagnostic utility (MDU) has been created for electronic module EGPL 081 P 07 (ID 1290). 2.7.2 Program Sequence Plans - G 7882, G 7882 CD (EGPL 081) x Fig. 6:Software Index P 03, Version 03 Descriptive Technical Documentation DTD no. 62-7881 070-15 18.09.2013, US_am This information should not be duplicated or passed on without Miele approval.
