Fan Coastdown; Door Contact Switch (S24); Release Element (Y56) For Steam Reduction - Miele DG 408 Series Technical Information

DG 408x Steam Ovens
to the air duct (Figure 010-1, Item 2). The fan draws in cool air through the air
vents in the housing, and the cool air mixes with the vapors in the air duct
(Figure 010-1, Item 4). The cool air/vapor mix is expelled through the gap
between the fascia and the oven cavity (Figure 010-1, Item 3). Excess steam
from the steam generator is carried directly to the fan via the vent hose
(Figure 010-1, Item 6) and pushed out at the front of the appliance. Shortly
before cooking time is up, relay K1/61 activates the release element, which
causes a metal rod to slowly open the door a crack. This reduces the steam
in the oven cavity. See Figure 010-1, Item 5. Once the buzzer sounds to
indicate the end of cooking time, the door slowly closes.

Fan Coastdown

To reduce the vapors that are still in the oven cavity after cooking has ended,
the fan continues running after the appliance is switched off.
This prevents
steam from settling on the fascia of the cabinetry when opening the door
condensate from forming in the housing by residual steam.
Coastdown duration depends on whether or not the steam generator has
been removed from the appliance after the cooking process. Warm cooked
food in the appliance delays the cooling and leads to a longer coastdown
time. Coastdown time is not adjustable!
If steam generator was removed: Coastdown takes at least 8 minutes. If
after the first 8 minutes the interior temperature has not dropped below
113°F (45°C), then the coastdown time is extended for an additional 8
minutes until the interior temperature drops below 113°F (45°C).
If steam generator was not removed: Coastdown takes at least 60
minutes. If after the first 60 minutes the interior temperature has not
dropped below 113°F (45°C), then the cooldown time is extended for an
additional 8 minutes until the interior temperature drops below 113°F
(45°C).
2.3

Door Contact Switch (S24)

If the door is opened during the cooking process, the door contact switch
signals the control electronic, which switches off the steam generator heater
(1R25, 2R25).
Note:
With the door open a crack, new cooking selections can be made.
However, the steam generator heater will not be switched on for
approximately one to two minutes.
2.4

Release Element (Y56) for Steam Reduction

Shortly before cooking time is up, relay K1/61 activates the release element,
which slowly opens the door a crack. This reduces the steam in the oven
cavity. After the buzzer sounds to signal the end of cooking time, the door
slowly closes again.
While the door is open a crack, new cooking selections can be made.
However, the steam generator heater will not be switched on for
approximately one to two minutes.
