Why is my Qualcast Q1W-SP16-1900 not building pressure?

If your Qualcast Pressure Washer is not building up pressure, or the pressure is very low, there might be air in the system. If so, ventilate the machine by running it without the high-pressure hose until water flows without bubbles, then re-attach the hose. Also, the issue might be with leaks in the inlet pipes leading to the pump, a blocked hose, or a kink in the pipe.
