Answer:
- The Convection Steam Oven water tank holds approximately 5 cups of water.
- Legacy Convection Steam Oven water tanks hold approximately 4 cups of water.
- There is not a fill line on the water tank.
Water Tank and Lid Removal:
- The top lid fits tightly on the water tank but is removable.
- Pull up to remove the lid.
- If the water tank is stuck in the opening, wiggle it back and forth while pulling out to release it.
Legacy Convection Steam Oven Water Tank:
- The water tank in a Legacy CSO provides approximately 90 minutes of continuous steam.
- Most modes do not use continuous steam, so actual cooking time on one tank may be longer. For example, Slow Roast uses steam but not in a continuous flow, so one tank of water may last several hours.
- Refer to Legacy Convection Steam Oven Cooking Modes for more information on which modes use steam and when.
Convection Steam Oven Plumbed Model Water Tank:
- In CSO plumbed models, the home water supply provides continuous steam for specific cooking modes.
- In CSO plumbed models, the water tank is only used for descaling.
- Refer to Convection Steam Oven Cooking Modes for more information on which modes use steam and when.
- If the unit is not hooked up to the home water supply, it is possible to use the water tank for cooking if needed. The water tank will provide approximately 4 hours of steam.
- In the event that the unit does run out of water, "fill water tank" will appear on the display screen.
- If the "fill water tank" message is ignored, the unit will eventually power itself off as a safety precaution.
- Refer to Convection Steam Oven Fill Water Tank Message for more information.
- Add no more than 2 cups of water to prevent overflow when the unit pumps water from the boiler back into the tank.
- There is a baffle in the tank to prevent water from splashing when filled.
