Why does my Graco QUANTM i30 beep and show a yellow light?

If your Graco Water Pump emits a beeping alert sound and the LED light is yellow, it could be due to the pump starting its automatic startup sequence because it is connected to a power source while the control knob is not in the off position. To resolve this, turn the control knob to the off position or disconnect the power. Alternatively, if you intend to operate the pump, allow it to complete the automatic startup sequence.
