CW-3000 water chiller beeps constantly and no water flow

A customer bought a CW-3000 water chiller to cool 80 watt CO2 laser cutter, when he filled up the tank and connected the IN/OUT hoses to the laser, and then the Alarm Light is ON and beeps 3 times pauses and beeps 3 times constantly. At the same time, he found the water temperature and the fan in the back is working but NO water flow.
