elements (1R25, 2R25), (Figure 040-1, Item 6), to heat the water in the inner
chamber. As water evaporates from the inner chamber, it is automatically
replenished with water from the outer chamber.
2.1.2 Water Level
The electronic continuously displays the water level, which is automatically
calculated by the electronic using a float (with magnet) within the steam
generator (Figure 040-1, Items 3 and 3a) and the water level float switch
(S12) (Figure 040-1, Item 4). After a pre-set heating countdown, the steam
generator heater element steam switches off and the display prompts the
user to add water.
2.1.3 Steam Generator Present Switch (S84)
The steam generator present switch registers if the steam generator is
installed in the appropriate position.
2.1.4 Heating
The steam generator can only be activated when
The steam generator switch is activated by the presence of the steam
generator (Figure 040-1, Item 5)
The water level float switch registers a sufficient quantity of water is
present within the steam generator (Figure 040-1, Item 4)
The oven door is closed.
During the heating-up phase, generally both heater circuits are activated.
In the maintenance phase, after the required temperature has been reached,
only one heater circuit is cycled (on/off) to maintain the oven cavity
temperature. If the temperature drops below a certain threshold, e.g., after
the oven door is opened, both heater elements may be activated.
3 Fault Repair
3.1 Appliance Does Not Heat
1. Ensure that the appliance is electrically connected to the proper supply.
2. Ensure that the appliance is NOT in the “demonstration mode”.
3. Ensure that the proper steam generator is being used. If a steam
generator from a different model number (e.g., DG 2xxx) is used it can
result in adverse operation.
3.2 Appliance Heats Too Slowly
1. Ensure that the appliance is electrically connected to the proper supply.
2. Ensure that the appliance is NOT in the “demonstration mode”.
3. Ensure that the proper steam generator is being used. If a steam
generator from a different model number (e.g., DG 2xxx) is used it can
result in adverse operation.
