The water tank is on the right side of the steam oven. It holds 1.4 quarts (1.3 L) of water. The water tank is not dishwasher 
safe. 

Water level sensor warnings:

The water tank must have enough water to generate the steam needed for the cooking mode and time you are using. As 
the water is converted to steam, the tank level will drop during cooking. Three different water levels are monitored by the 
oven:

 

Important notes about the water used to fill the tank: 
•

Moisten the seal in the tank lid with some water before 
using it for the first time.

•

Use only fresh tap water or, if necessary, plain non-
carbonated purchased water to fill water tank. 

•

If your water is very hard (10 grains per gallon or 
higher), we recommend using softened water.

•

If your tap water is highly chlorinated (>40 mg/L), use 
plain non-carbonated purchased water with a low 
amount of chlorine.

Check the water hardness using the test strip provided or 
ask your water utility company.
