9 Fill water tank with a bit more than 1 L of water. Any more than that is diluting it. Breville instructions say fill to the water line but sounds like dilution to me.
Breville also says fill with cold water whereas back of Breville descaler packet says warm water. Go with warm because dissolving is easier in warm.
