Flushing the electric Combitherm steam generator on a daily basis helps to prolong the life of the steam
generator heating elements and helps prevent the necessity of service requirements. The control provides
this feature as an automatic function when the oven ON/OFF power key is pressed to the ON position at the
start of each working day.
PRESS THE ON/OFF POWER KEY TO THE ON POSITION.
DISPLAY MESSAGE INDICATES:

1. Press the Power Switch to the OFF position. Rotate the Steam Generator Drain Cap located at the back
of the oven until water begins to flow from the four holes in the cap. In approximately 20 to 60
seconds, a sufficient quantity of water will have drained from the steam generator so that the drain cap
can be completely removed.
2. As the water continues to flow from the generator, it will have a milky or cloudy appearance, which
indicates deposits in the generator are beginning to flush through the system. Let the water continue to
drain until the flow begins to subside.
3. When the flow begins to subside, remove the hand-held hose from the side of the oven and direct a
stream of fresh water directly into the steam generator drain opening located directly behind the Steam
Generator Drain Cap. Repeat this procedure several times until the water begins to run clear.
4. Press the oven Power Switch to the ON position. When the audible signal is heard, press the Steam
Mode Key. A new supply of fresh, cold water will begin to flow through the steam generator. Repeat
this procedure several times until the water runs completely clear.
5. Once the water is completely clear, replace the Steam Generator Drain Cap over the steam generator
drain by turning it clockwise, by hand, until there is a slight resistance.
