Mine did the same thing. the tub is plugged into a ground fault interupter (gfi) plug. hit the reset button. if this doesn't work, check the circuit the gfi is on, sometimes they are on the same circuit as the plugs at the sink. check them for reset also. if this fails, on the motor of the tub, there should be a reset button. try to reset it. OH first make sure the breaker has not been tripped.
