Yes the griddle is removable for washing but the probe holes could still get wet. Our last griddle( not dash) quit working from corrosion in those holes. Yes you need to let it dry completely before use. It is easy to wash in the sink without the base. Read the manual.The griddle works great for our daily pancakes and bacon. I'd like to try hamburgers but worry about heating where there is no food to cook. I have several Dash products and they are durable and I do use them.
