B. Cavity set point temperature (default) is
displayed in the temperature display then
reverts to the actual cavity temperature.
C. Press combi key an additional 1 to 5 times
to increase the steam factor setting from
10 to 50. With each successive key press,
an additional LED illuminates to indicate
the setting. The default steam factor
setting is 5 (one LED on).
D. Steam generator fill solenoid is energized
until proper water level is reached then
turns off. See “WATER LEVEL
SENSORS” under “COMPONENT
FUNCTION”.
E. First LED for the cooking program phase
flashes.
