The machine is on but it doesn’t suck paint

DP-X6 Portable Electric Airless Paint Sprayer

DP-X6 Electric Airless Paint Sprayer with Gun & Hose

  1. the suction ball get stuck, or the outlet ball get stuck. The ball could be stuck with the ball seat during the long period of transportation or stock for over 1 month. so you need to use a wrench to punch the fluid pump (at the position of suction valve & outlet valve), and when the ball move a little, then the paint could be sucked immediately.
  2. the machine is overloaded, it has too much material in it.For example one or more of the different filters or even the airless spray gun nozzles are obstructed with material. The possible points of obstruction would be:
  • The suction filter
  • The main filter
  • The gun filter
  • The nozzle has a paint jam

This may be the reason why the airless sprayer doesn’t work, the motor runs but it does not suck. What can we do? Check that the filters and nozzles are clean, and if they are letting the material flow. Best thing to do is to remove and clean them or if they are damaged replace them.

3. check the position that the pressure valve is in.The pressure valve controls the direction in which the paint is flowing. This valve has two positions:

Flowing back to the container

Flowing through the hose and to the gun in normal work position

When starting a project after a long pause, it’s very possible that they will be air inside our device. Before we start working, we need to empty the machine. First we have to make the air flow back and out of the machine.As soon as the material starts to flow out of the equipment, that means the equipment is empty of air. We can now change the valve position to the working mode, so it can flow forward.

Another recommendation is to check that the suction system has enough material and it’s covered with it, especially the filter must be covered by paint. Sometimes it can happen and by working vibrations, the filter goes up a little bit, so it just floats and it’s not submerged.

If there is not enough material to cover the filter, the device won’t work in its best performance. So, please remember to check this too!
