First consider the cause of insufficient water inflow. If the motor can run normally.
Therefore, I provide here a simple method to test the water inflow flow
Remove the nozzle from the high-pressure water gun. Watch to see if enough water comes out of the muzzle.
If the water output is still relatively small without a nozzle, it proves that there is a problem with your water inlet. You need to consider the above three points.
Insufficient water pressure and flow may be caused by the following reasons:
1. The incoming water comes from the water tank (the incoming water pressure is less than 0 BAR). Usually, pumps below 15 liters can only inhale incoming water within 3 meters. Of course, this is related to the height of the water tank. The water tank usually cannot be lower than the cleaning machine.
2. The water inlet comes from tap water (theoretically speaking, the water inlet pressure is greater than 0BAR), but there may be a leak in a certain water inlet or water inlet pipe, which will lead to insufficient water inlet.
Secondly, the setting problem of the pressure regulating valve leads to low pressure in the cleaning machine. Excessive laxity or tightness of the pressure regulating valve will cause the cleaning machine to not work properly, so the pressure regulating valve needs to be loosened. Restart the machine and slowly tighten the pressure regulating valve spring. Yes the pressure is slowly rising.
