    What to do if fluid is spitting from the gun of my Graco 17С327 Paint Sprayer?

      If your Graco Paint Sprayer is spitting fluid from the gun, it could be due to a few reasons. There might be air in the pump or hose, so check and tighten all fluid connections, and cycle the pump slowly during priming. Another possibility is a partially clogged spray tip, which you should clear. Also, ensure that your fluid supply isn't low or empty, and refill it if necessary, then prime the pump.

    Why is my Graco 17С327 pump difficult to prime?
    • M
      Mia BryantAug 22, 2025
      If you're finding it difficult to prime your Graco Paint Sprayer, consider these potential causes. Air in the pump or hose can be a culprit, so check and tighten all fluid connections, and cycle the pump slowly during priming. A leaking intake valve can also make priming difficult; clean the intake valve, ensuring the ball seat is in good condition. Worn pump packings may also be the cause, and in that case, you would need to replace them. Lastly, ensure the paint isn't too thick, and thin it according to the supplier's recommendations.

      Amanda BowmanAug 25, 2025
      If you notice excessive paint leakage into the throat packing nut of your Graco Paint Sprayer, there are a few possible reasons. The throat packing nut might be loose; remove the spacer and tighten the nut just enough to stop the leakage. Alternatively, the throat packings could be worn or damaged, requiring replacement. Also, the displacement rod might be worn or damaged, and would need to be replaced.

    Why is the pump output low on my Graco Paint Sprayer?
    • J
      jacobwatsonAug 28, 2025
      If the pump output is low on your Graco Paint Sprayer, several factors could be responsible. First, check if the spray tip is worn and replace it if necessary. A clogged spray tip can also reduce output, so relieve the pressure and clean it. Ensure that you have enough paint supply and reprime the pump. Inspect the intake strainer for clogs, and clean it if needed. Also, a clogged fluid or tip filter can cause this issue, so clean the filter. Finally, leaking from the prime valve can lead to low pump output, so repair the prime valve.

      Adam MorrisAug 30, 2025
      If the motor runs but the pump doesn't stroke on your Graco Paint Sprayer, it could be due to a damaged connecting rod assembly, which would need replacement. Alternatively, the gears or drive housing might be damaged, requiring inspection and possible replacement.

    Why Graco 17С327 Paint Sprayer does not run and the control board status light blinks 6 times?
    • B
      Brad RodriguezSep 2, 2025
      If your Graco Paint Sprayer doesn't run at all and the control board status light blinks 6 times repeatedly, it could be due to the motor being hot or a fault in the motor thermal device. Allow the sprayer to cool down. If it runs when cool, address the cause of overheating by ensuring the sprayer is in a cooler location with good ventilation and that the motor air intake isn't blocked. If it still doesn't run, replace the motor. Make sure to check the thermal device connector at the control board and measure the resistance of the thermal device.

    Why does my Graco 17С327 Paint Sprayer stop after running for a few minutes?
    • D
      Diamond WarrenSep 4, 2025
      If your Graco Paint Sprayer operates for only 5 to 10 minutes and then stops, the pump packing nut might be too tight. This restricts pump action and overloads the motor. Loosen the pump packing nut, and check for leaks around the throat. If necessary, replace the pump packings.

    What to do if Graco Paint Sprayer does not run and control board blinks 5 times?
    • A
      amanda83Sep 7, 2025
      If your Graco Paint Sprayer doesn't run and the control board status light blinks 5 times repeatedly, the control might be commanding the motor to run, but the motor shaft isn't rotating. This could be due to a locked rotor, an open connection between the motor and control, a problem with the motor or control board, or excessive motor amp draw. Remove the pump and try to run the sprayer. If the motor runs, check for a locked or frozen pump or drive train. If it doesn't run, disconnect the motor connector(s) from the control board socket(s), ensuring the contacts are clean and secure. Then, spin the motor fan and restart the sprayer. If it runs, replace the control board.

      Tina StarkSep 10, 2025
      For basic electrical problems with your Graco Paint Sprayer, ensure the motor leads are securely fastened and properly mated. Replace any loose terminals and crimp them to the leads, ensuring they are firmly connected. Clean the circuit board terminals and securely reconnect the leads. Also, inspect the motor armature commutator for burn spots, gouges, or extreme roughness, and have a motor shop resurface the commutator if possible.
