A starting system for a pump includes a driving motor, an electric source, a
selector
switch, a starter sensor, a temperature sensor and a control unit. The selector
switch is located between the driving motor and the electric source for reversing
polarity of the electric power supplied from the electric source to the driving
motor. The starter sensor senses whether or not the driving motor has been started.
The temperature sensor senses a temperature. The control unit operates the selector
switch so as to repeatedly give the driving motor indications of reverse rotation
and normal rotation in a case where the starter sensor does not sense that the
driving motor has been started even if the control unit operates the selector switch
so as to give the driving motor the indication of normal rotation in a state where
the temperature sensed by the temperature sensor is below a preset temperature.
