Is the sprayer turning on?
Is it priming?
Does it spray at all?
There are several causes:
1. The needle is held open with debris.
2. The grey nut at the back of the gun is turned too tight, loosen it slightly.
3. The needle may be worn and needs to be replaced. Have the gun serviced or install a new repair kit for the specific gun you are using.

Follow these steps:
Make sure the unit is plugged into a working outlet. If it is, turn the sprayer on and then turn the sprayer’s pressure control knob clockwise until the motor starts running.
When the gun trigger is released, the motor and pump will automatically turn off. Once you pull the gun trigger and start spraying, the motor and pump will turn on again. This is normal operation and eliminates constant motor noise and reduces wear for longer life.
If the motor continues to run when the gun trigger is released, it is not primed.
Make sure the Prime/Spray Valve is pointed forward in the Spray position
The spray tip is likely clogged. Turn the spray tip 180 degrees to the unclog position, aim the spray gun into a bucket and pull the trigger for one second to clear the clog. Turn the spray tip back to the spray position and resume spraying.
The best way to reduce tip clogs is to strain you paint of the larger debris.
Make sure the pressure control is turned up to a higher spray pressure. Try moving closer to the surface. If you continue to see lines in your pattern, you may need a larger tip size if you sprayer can support it (the largest tip that the Project Painter Plus and X5/LTS15 can support is the tip that is included). Otherwise, add a small amount of water or solvent, depending upon your material. Be sure to work the water or solvent into the paint that is in your paint hose by reversing the tip and spraying the paint back into the paint bucket until the thinner material is worked into the paint hose. Don’t forget to turn your spray tip back to the spray position.
You most likely have a tip plug. Turn the spray tip 180 degrees to the unclog position, aim the spray gun into a bucket and pull the trigger for one second to clear the clog. Turn the spray tip back to the spray position and resume spraying.
The pump needs to be serviced or replaced.
The spray hose connection is not tight. Use a wrench to tighten the spray hose to the sprayer and to the gun.
Slowly increase pressure setting to see if motor starts.
