Cleaning and Maintenance Cuisinart CSO-300NC

Always allow the oven to cool completely before cleaning.

To clean the interior walls, you can first loosen food debris by running the Steam cycle function. Follow the Operating Instructions, using the Steam function default [30 minutes at 210˚F (99°C)]. Once cycle is complete wipe interior with a cloth or sponge. DO NOT use harsh abrasives or corrosive products, which could damage the oven wall surface.

Note: If oven is not in use for more than 1 month, fill water reservoir and run oven on Steam function at 210˚F (99°C) for 60 minutes before using.

How to Drain the Internal Water Tank

Your steam oven is equipped with a water drain so you can empty the internal water tank. The drain outlet is at the rear of the oven. We recommend that you drain the tank when you do not plan to use your oven for an extended period of time. You should also drain the tank at the end of each decalcification process.
To drain the tank, follow these steps

Remove the external water reservoir from the oven by lifting it vertically using the handle.
Position a tray, short bowl or other container under the rear drain to catch the water.
Turn the cap counter-clockwise to remove the cap and open the drain. Open the drain slowly to ensure you catch the water in your container.
Tilt the oven back slightly as necessary to empty all of the water from the tank.
When finished, replace the cap by rotating it clockwise until secure. Do not over-tighten.

Decalcification of Steam and Convection

Decalcification refers to the removal of calcium deposits that form over time. These deposits can cause damage to the machine. For best performance from your Combo Steam + Convection Oven, decalcify annually for average use and twice a year for heavy use.

To decalcify

Remove the reservoir from the unit and empty it completely.
Drain internal water tank as described in the above section. Add 1 cup (250 ml) of water and 1 cup (250 ml) of distilled white vinegar to the reservoir. Return reservoir to the unit. Wait 30 seconds and press the program button to reset the Steam function at 210˚F (99°C) for 75 minutes. Press the Start/Cancel button and let the oven run until the "Add water" alert sounds.
Remove the reservoir from the unit and empty it completely. Set oven to the Steam function at 210˚F (99°C) for 30 minutes. Press the Start/Cancel button and let the oven run until the "Add water" alert sounds.
While the unit is running, add 1 cup (250 ml) of water and 1 cup (250 ml) of distilled white vinegar to the reservoir. When the “Add water” alert sounds, return reservoir to the unit. Wait 30 seconds and press the program button to reset the Steam function at 210˚F (99°C) for 75 minutes. Press the Start/Cancel button and let the oven run until the "Add water" alert sounds.
Remove the reservoir and rinse out with fresh clean water. Fill the reservoir halfway with clean water. Return the reservoir to the unit.
Wait 30 seconds and press the program button. Oven will resume from the point at which the cycle was interrupted. Let the oven run until the "Add water" alert sounds or the timer runs out. Drain the internal water tank again to fully flush out the system.

Troubleshooting

Why is my unit beeping?
Steam reservoir is empty. Remove and refill with water, then replace.
Why is water is leaking onto the counter.
Drip tray is not in place, or it may be full. Always check before each use and empty after use.
