Ice making method and ice maker

The invention provides an ice making method and an ice maker, and relates to the technical field of ice making. The ice making method comprises the following steps: starting a hot air valve, and heating an ice tray; starting a water inlet electromagnetic valve, detecting the water level value in a water storage tank by a water level probe, and switching off the water inlet electromagnetic valve when reaching preset water level value; pumping water in the water storage tank by a water pump, and flushing the ice tray; starting a water draining electromagnetic valve, draining the water in the water storage tank, and switching off the water draining electromagnetic valve; starting the water inlet electromagnetic valve again, detecting the water level value in the water storage tank by the water level probe, and switching off the water inlet electromagnetic valve when reaching the preset water level value; switching off the hot air valve, cyclically pumping the water in the water storage tank by the water pump, sp
