Water-free detection method for iron with water pump and iron with water pump

The invention discloses a water-free detection method for an iron with a water pump and the iron with the water pump. The method comprises the steps that S1, a heating disc is preheated; s2, judging whether a gear temperature is reached or not, if so, executing S3, and if not, executing S1; s3, heating to a gear temperature, allowing to start a steam function, and then executing S4; s4, identifying whether a user starts a steam function or not, if so, executing S5, and if not, executing S3; s5, whether heating is carried out or not is recognized, if yes, the step S3 is executed after the timing T1 and the timing T2 are cleared, and if not, the step S6 is executed; s6, T1 timing is carried out, whether T1 reaches first time or not is judged, if yes, S10 is executed, and if not, S7 is executed; s7, judging whether a steam function is started or not, and if so, executing S8; if not, executing S9; s8, accumulating and timing the T2, and then executing S5; s9, the T2 stops timing, and then the S5 is executed; and
