What to do if my Graco 190ES Paint Sprayer motor won’t operate?
- G
  glangAug 1, 2025
  If your Graco Paint Sprayer motor won’t operate, try the following: First, slowly increase the pressure setting. If that doesn't work, the spray tip or fluid filter may be clogged, so relieve the pressure and clear the clog or clean the gun filter. If water or water-based paint has frozen in the sprayer, thaw it completely in a warm area before starting. If paint has hardened, replace the pump packings. Also, check the displacement pump connecting rod pin and ensure it is in place and secured with the spring retainer. If the fan still won’t turn, replace the motor.

  If the motor runs and the pump strokes, but no paint is coming out of your Graco Paint Sprayer, ensure the prime valve is closed. Check and refill the paint supply, then re-prime the pump. Remove, clean, and reinstall the intake strainer if it's clogged. Tighten the nut on the suction tube and check the o-ring if the suction tube is leaking air.

  If your Graco Paint Sprayer motor runs but the pump does not stroke, replace the pump pin if it is missing, and ensure the retaining spring is fully in the groove around the connecting rod. If the connecting rod assembly is damaged, replace it. Inspect the drive housing assembly and gears for damage, and replace if necessary.

Why is my Graco Paint Sprayer motor hot and running intermittently?
- V
  vwilliamsAug 21, 2025
  If your Graco Paint Sprayer motor is hot and runs intermittently, it might be due to several reasons. Ensure the ambient temperature is not above 115°F (46°C) and that the sprayer is not in direct sunlight; move it to a cooler, shaded area if necessary. Also, check the motor for burned windings by removing the positive (red) brush and inspecting for burned commutator bars, and replace the motor if found. Lastly, check the tightness of the pump packing nut; if it's too tight, loosen it to prevent restricted pump action and damage to the packings. If there's leaking around the throat, replace the pump packings.
