What to do if Graco FinishPro GX19 runs but pump doesn't prime?
- S
  Scott HernandezAug 18, 2025
  If your Graco Paint Sprayer runs but the pump isn't priming or loses prime while in use, first, try pressing the PushPrime button to dislodge the ball, or power flush the sprayer. Ensure the Prime/Spray Valve is in the PRIME position until paint exits the drain tube. If you're using thick fluids, prime the pump with oil or water-based flushing fluid. Check the inlet strainer and make sure the suction tube is immersed in paint. Strain the paint to remove any debris. For thick or sticky paint, try momentarily turning the ON/OFF switch off and on several times. Inspect the suction tube connection for any cracks or vacuum leaks. Clean the outlet valve assembly and check if the inlet valve check ball or seat is dirty.

  If your Graco Paint Sprayer is spraying paint that runs down the wall or sags, move the gun faster. Also, choose a spray tip with a smaller hole size, use a spray tip with a wider fan, and ensure the gun is far enough from the surface.

Why does my Graco FinishPro GX19 Paint Sprayer make no sound when turned on?
- B
  Brenda GeorgeSep 7, 2025
  If your Graco Paint Sprayer makes no sound when the pressure control is ON and the ON/OFF switch is ON (illuminated), replace the battery with a charged battery. If the battery has reached the end of its life, replace it. If the motor is damaged, replace the motor. If the ON/OFF switch light blinks three times, allow the battery to cool down or warm up to room temperature. If the light blinks four times, replace the pump and/or motor assembly. If the light blinks five times, allow the motor to cool down to room temperature.
