Dish-washing machine control method and device, dish-washing machine and storage medium

The invention discloses a control method and device of a dish-washing machine, the dish-washing machine and a storage medium. The method comprises the steps that the water hardness change trend of multiple water hardness measured values of an inner container within preset time is determined; when the change trend of the water hardness is increased, the regional water hardness of the place where the dish-washing machine is located is obtained, and the water inflow of the activated water is determined based on the regional water hardness; and injecting the water inlet amount of activated water into the water softening container so as to activate the water softening raw material in the water softening container. According to the technical scheme, when the change trend of the water hardness is increased, the water inlet amount of the corresponding activated water is determined based on the obtained regional water hardness, the activated water with the water inlet amount is injected into the water softening contai
