This application relates to the field of ice-making equipment technology, and discloses an ice-making device and its control method. The ice-making device includes an ice-making module for making ice and a refrigeration system for providing cooling capacity for ice making. The method includes: during the continuous operation of the refrigeration system for ice making, in response to meeting a preset drainage trigger condition, controlling the execution of a water replacement operation, the water replacement operation including: draining at least a portion of the water in the ice-making module; and after draining, resupplying water to the ice-making module. This application can inhibit scale deposition and maintain unobstructed venting, and reduces the impact on the ice-making speed.
