No, you should not put water or any liquids directly into the main unit of a slow cooker. The main unit, also known as the base or housing, contains the heating element and electrical components, and it is not designed to come into direct contact with water or liquids.
The proper way to use a slow cooker is as follows:
Place the removable ceramic or stoneware insert (the cooking pot) inside the main unit.
Add your ingredients and any liquids (e.g., broth, sauces, or water) to the cooking pot.
Put the lid on the slow cooker to cover the cooking pot.
Set the desired cooking temperature and time using the control panel.
The slow cooker works by heating the cooking pot indirectly through the transfer of heat from the base unit to the ceramic or stoneware insert. This gentle and slow heating method allows the ingredients to cook slowly over an extended period, resulting in tender and flavorful dishes.
Adding water or liquids directly to the main unit could damage the electrical components and pose a safety risk. Always make sure the cooking pot is properly placed inside the main unit and follow the manufacturer's instructions for safe and correct usage.
