CSO24 and CSO30 (SWS #13508346)Theory of Operation
3-6#9001333 - Revision A - August, 2014
Using the Temperature Probe
The probe monitors food temperature and announces when it has reached a temperature considered “done” and
safe for consumption. Using the probe also helps to maintain ideal tenderness. The internal temperatures shown in
the chart below are the USDA recommendations for safe food consumption and desired doneness may vary.
Positioning the Temperature Probe1. Insert the probe into the thickest part of the meat so that the tip is in the center of the meat. Bury the entire
metal shaft into the dish, or as much as is possible. To maintain accuracy, avoid touching bone or fat with the
probe as they conduct heat faster.
2. Insert the plug end of the probe into the socket located on the right interior oven wall behind the metal flap.
3. Ensure probe cable is neatly tucked inside of the oven interior. Close the oven door.
Setting the Probe Temperature1. Select the operating mode and cooking space temperature.
2. With the probe positioned and plugged in, press the TEMP button until the display reads ‘Probe Temperature’.
3. Turn the control knob to set the probe temperature based on the desired level of doneness and press to select.
Probe temperature appears in the left digital display when the temperature reaches 85°F or higher.

Preparing for First Use
CleaningClean the cooking space and accessories with warm, soapy water and a soft cloth.
Open the Water Tank1. Press the WATER button.
Always use this button to open the water tank. Trying to access the water tank manually will damage the oven.
Fill the Water Tank1. Fill the tank with fresh, cold tap water. Never fill the tank with demineralized, filtered or distilled water.
2. Close the lid.
3. Push the water tank into its compartment and ensure it is seated firmly.
The water tank holds enough water for 1.5 hours of continuous steam, typically enough for four or five cooking ses-
sions. In the event the tank needs refilling in the middle of a cooking session, add no more than 2 cups of water.
This will prevent overflow when water is pumped back into the tank.
Close the Water Tank1. Close the panel flap manually.
Before Using the First TimeHeat the empty cooking space without baking pans using auto steam bake mode for 30 minutes at 410°F.
Emptying the Water TankWhen the oven is turned off, residual water is pumped back into the water tank.
• “Water is being pumped off” appears in the text display. Residual water is not pumped back until its temperature
is below 175°F (79°C). If “Do not remove water tank” is displayed in the text display, the temperature of the
residual water is still over 175°F (79°C).
• When the water has been pumped back you may remove, empty and dry the water tank.
• When the symbols are no longer illuminated and the text display is dark, the oven is off.
• Any operating mode can be started again at any time
Checking and Changing Probe TemperatureThe TEMP button toggles between displaying the actual probe temperature and the set temperature.
1. To change the set probe temperature, press the TEMP button twice until the display reads “Probe Temperature”,
then turn the control knob to set a new temperature and press to select.
End of CookingWhen the set probe temperature is reached, the oven automatically turns off.
• “Probe temperature reached” appears in the text display, and the actual probe temperature appears in the left
digital display.
• The probe symbol will flash and an audible signal will sound for 1 minute.
• Probe temperature may continue to rise due to residual heat.

canning jars with steam.
Cooking Modes
Twelve cooking modes bring the world of modern food
preparation right into the kitchen. Steam mode perfectly
poaches fish. Auto steam bake turns out breads that are
tender inside and delightfully glossy and crusty outside.
Now you can enjoy meats, casseroles, breads, appetiz-
ers, desserts or multi-course meals with enhanced taste,
texture and appearance.
SteamFrom vegetables, poultry and fish to grains, beans, pasta
and egg dishes, gentle steam heat is ideal for capturing
nutrition, color and flavor.
Steam mode heats with steam and hot air, with a tem-
perature range of 85°F (29°C) to 210°F (99°C): just
enough heat to firm up a batch of homemade yogurt, or
greater steam heat to thoroughly cook meats and side
dishes to perfection.
Use the steam function for any food you would have
heated in a saucepan, and for all foods that would bene-
fit from gentle handling such as fish and seafood, veg-
gies and rices. Steam offers great flexibility. Cook meal
elements together such as chicken and rice or fish and
veggies without odor or flavor transfer. Prepare frozen
vegetables and defrost foods evenly without any hot
spots. Gently extract juices while preserving the integrity
of flavor, color, texture, shape and vitamin content.
ReheatReheat mode uses steam and hot air to rehydrate food
gently. Combining just the right balance of air convection
and rehydrating moisture, reheat mode warms one to
four pans of food evenly and without drying.
Reheat mode temperatures range from 210°F (99°C) to
300°F (149°C). Entrees, casseroles, sides and leftovers
are warmed to serving temperature without compromis-
ing quality. Frozen meals and convenience foods can
also be brought gently and thoroughly up to their ideal
serving temperatures. Bread baked days ago can be
regenerated at 300°F (149°C) for an aromatic, fresh-
from-the-oven crust and moist interior.
Use the reheat function for any food you would have
reheated in the oven, range or microwave with superior
results.

Auto Steam BakeBake just like a professional with auto steam bake mode. By heating with steam first, then using convection heat to
finish baking, bagels, breads, buns, rolls and pastries acquire a tender interior, a beautiful exterior and a natural
shine without the need for brushing with an egg wash. Auto steam bake mode temperatures range from 210°F
(99°C) to 445°F (229°C). Use this mode for breads, buns, cakes and pastries whether fresh, par-baked or frozen.
Do not preheat.
ConvectionA fan creates the movement of hot air created by a heating element at the back of the oven for convection cooking to
distribute heat evenly around food for consistent results and browning. Convection also eliminates odor transfer mak-
ing it ideal for cooking desserts, meats and vegetables all together.
Convection mode temperatures range from 85°F(29°C) to 445°F (229°C). Cooking temperatures versus traditional
ovens may be 25 degrees less, and times may be about 25% faster, saving valuable time and lowering energy costs.
Use convection mode for muffins, biscuits and roasts. Convection mode is also ideal for speeding up cooking time,
and for cooking different types of foods together at once to save time. For instance, add dinner rolls and aromatic
veggies like broccoli to your meat-cooking session without any odor transference to create a complete meal where
every menu item is conveniently cooked together, and is done at the same time.
Convection HumidIn convection humid mode, a heating element at the back of the oven produces heat and oven ventilation is sealed
so that moisture produced during cooking remains in the oven.
Convection humid temperatures range from 85°F(29°C) to 445°F (229°C).
Use convection humid for cakes, casseroles, grain dishes, lasagna and meats.
Convection SteamConvection steam is great for roasting vegetables, grains or potatoes, and multiple items together, like a 12-pound
turkey with trimmings. Cook the turkey with steam, then add vegetables or potatoes, turn off steam, and it will all
roast and be done together. You control the steam supply.
Convection steam mode temperatures range from 85°F(29°C) to 445°F (229°C). Steam transfers energy to the food
more efficiently than hot air alone, which speeds up the cooking process. Food retains its own moisture and delicate
parts are more resistant to burning.
Use convection steam for any foods you want to be tender inside and roasted or crisped outside.

GourmetGourmet cooks food to perfection; simply tell it what type of
food you are putting inside of the oven. The climate sensor
knows the amount, shape and consistency and adjusts
time, temperature and humidity so no baking instructions
are required.
Select your item and preferred level of doneness. After a
few minutes it will tell you when your dish will be ready.
Great results are achieved easily, quickly and stress-free.
Use Gourmet to prepare any of the foods in the table at
right, whether they come fresh from your garden, refrigera-
tor, freezer or pantry:
Slow RoastSlow roast mode is the ultimate convenience. Insert the
probe into your prepared meat, select a slow roast setting,
tell the oven what time you want it done, and come home to
a perfectly cooked meal.

Recipes ModeUse the recipes mode for an easy and fun way to cook entire meals from appetizers and entrees to desserts. The
recipes are listed by code in the chart below.
The recipe collection harnesses the power of many different cooking modes. All you need to do is place your food
into the cooking space, turn the control knob to recipes, make your selection, and choose the number of portions or
level of browning. The oven determines the rest of the details for you and never overcooks, for delightful results.
The recipes mode is ideal if you are in a hurry, looking to try a new recipe, or need to prepare a variety of food for a
party or social occasion.

My RecipesIt’s easy to cook all your favorite recipes with a convection steam oven for healthier fare that tastes better than ever,
makes meal preparation stress-free, and the cleanup a snap.
With my recipes you can add ten of your favorite recipes, and replace or edit them at your pleasure. Recipes may
also be copied into my recipes, and even edited as you see fit.
Keep WarmSometimes great food cannot be enjoyed when it’s hot from the oven. Instead of cooling it, putting it in the refrigera-
tor, and then warming it again in the microwave, simply use the keep warm mode. Food can even be plated and
multiple dinner plates can be kept warm at once, making staggered mealtimes more convenient.
The combination of convection and steam heat preserves food’s taste, texture, looks and quality so every bite is as
delicious as if it were fresh from the oven.
CleanseCleanse mode is ideal for baby bottles and canning jars. Using steam in a contained environment, the cleanse
process is less fussy, faster, and safer than conventional methods.

Food Probe Socket Assembly
To remove the food probe socket assembly, the top and
back panel will need to be removed first, then (See
Figure 4-28):
1. Using a tin-snips or similar tool cut the metal bridge
at the four corners of the perforated probe socket
cover.
2. If foil insulation is present, use a knife to carefully cut
the foil covered insulation along the edges of the
opening and pull the insulation out.
3. Disconnect all electrical leads from back of probe
socket.
4. Inside the cavity open the door of probe assembly
and hold the nut around the probe socket stem.
5. While holding the nut around the probe socket stem,
rotate back of probe socket counterclockwise until
nut around the probe socket stem inside cavity is
removed, then lift socket from hole.

Table of Contents
1. Malfunctions with Error Codes .......................................................................................................................... 5-3
2. Malfunctions/Messages Without Error Codes .................................................................................................... 5-9
3. Malfunctions Without Fault Displays//Messages ............................................................................................... 5-10
4. Switching Demo-Modus ON/OFF ...................................................................................................................... 5-10
5. Diagnostic Mode (History and Counters) .......................................................................................................... 5-11
NOTES:• If the appliance has an error, that error code will appear on the display when it is happening to the appliance
without entering diagnostic mode.• Though not listed, the cause of all error codes could be the result of, in rare cases, other factors such as:
- Faulty wiring e.g. through a short circuit, break, loose contact, earth contact, etc.- Problems with the electronics assembly groups, caused by moisture, dirt, component failure, EMC influ-
ences, etc.• Before continuing, please take note of the WARNINGS and CAUTIONS below.
• TO AVOID ELECTRIC SHOCK, NEVER TOUCH ANY PART OF THE ELECTRICAL CIRCUIT WITH HANDS OR
UN-INSULATED TOOLS WHILE THE POWER IS CONNECTED.
• FAILURE TO INSTALL THE MOUNTING SCREWS CAN ALLOW THE OVEN TO TIP FORWARD DURING USE!
Be careful when handling sheet metal parts - Edges may be sharp.
