description The invention provides a control method of a water pump, and belongs to the technical field of water pumps. The control method solves the technical problem that an existing water pump is inaccurate in control. Sensors used for detecting pressure and temperature are arranged at the outlet end of the water pump. The control method comprises the following steps that a, electrifying and starting are performed: after waiting for 3s after electrifying for the first time, the water pump is started; and b, the shutdown pressure is set to be P1, the starting pressure is set to be P2, the pressure of the outlet end of the water pump is detected to be P3 through the sensor, the temperature of the outlet end of the water pump is detected to be T through the sensor at the fixed frequency, the T is calculated as+1 when rising once and is calculated as minus 1 when falling or not changing once, and the sum value is calculated as M in a continuous time period, wherein the range of the P1 is [P1min, P1max], and P1min is equal
