Why is my Graco Ultimate Mx II 795 Paint Sprayer not spraying with enough pressure?
- Q

  If you're getting low output or pressure from your Graco Paint Sprayer, several things could be the cause. Here's what to check: * A worn or clogged spray tip: Replace or clean it. * Low paint supply: Refill and reprime the pump. * Clogged intake strainer or filter: Remove and clean them. * Loose suction hose connections: Tighten them and check for damaged seals. * Leaking prime valve: Repair it. * Worn packings: Replace them, and check the piston valve seat.

What to do if my Graco Ultimate Mx II 795 Paint Sprayer shows error E=02?
- H
  hannah36Aug 21, 2025
  If your Graco Paint Sprayer shows the error code E=02, it means the control board is getting too much pressure signal from the transducer, which could be damaged or the fluid path might be blocked. First, check the fluid path for any clogs, such as a clogged filter. If you're using AutoClean, open the prime valve and gun. Make sure you're using an airless paint spray hose without metal braid, and it should be at least 1/4 inch x 50 ft. Smaller hoses or those with metal braid can cause high-pressure spikes. If the fluid path isn't clogged and you're using the right hose, try replacing the transducer.

  Andrew ParkerAug 25, 2025
  If your Graco Paint Sprayer isn't running or stops, try these steps: First, plug the sprayer into a grounded outlet with the correct voltage. Next, turn the power switch OFF for 30 seconds and then back ON to ensure it's in normal run mode. If that doesn't work, turn the pressure control knob up by half.

  If your Graco Paint Sprayer displays error code E=06, it could mean the motor is too hot or there's a bad connection with the motor/thermal device. Start by checking all the wire connections from the motor to the control board. If the connections are fine, let the sprayer cool down. If it runs when cool, find out why it's overheating. Keep the sprayer in a cooler spot with good airflow and make sure the motor's air intake isn't blocked.

  If your Graco Paint Sprayer shows error code E=05, it might mean the pump or drive is locked, or there's a motor connection or wiring problem. First, check the motor wiring connections. Then, check for a pump or drive train that's locked or frozen. If the wiring is okay and the pump/drive train isn't locked, replace the motor.

What does error code E=03 mean on my Graco Ultimate Mx II 795 Paint Sprayer?
- A
  Alexander DennisAug 30, 2025
  If your Graco Paint Sprayer displays error code E=03, it indicates a transducer or transducer connection error. Start by checking the transducer connection. Disconnect and reconnect the transducer plug to ensure it's making good contact with the control board socket, and check the transducer contacts. Open the prime valve. Connect a known good transducer in place of the sprayer transducer and turn the sprayer ON. If the sprayer runs, replace the transducer. If it doesn't run, replace the control board.

Why is the motor running but the pump isn't stroking on my Graco Paint Sprayer?
- J
  Jessica PatelSep 1, 2025
  If your Graco Paint Sprayer motor runs, but the pump doesn't stroke, the displacement pump pin might be damaged or missing. Replace the pump pin if it's missing. Also, make sure the retainer spring is fully in the groove all around the connecting rod. Check the connecting rod assembly for damage and replace it if needed. Inspect the drive housing assembly and gears for damage and replace if necessary.

  If your Graco Paint Sprayer shows error code E=07, it means the sprayer exceeded 2000 psi during the timed flush cycle. Make sure the prime valve and gun are open. Also, ensure there are no flow obstructions or a clogged filter.

  If your Graco Paint Sprayer displays error code E=10, it indicates a high control board temperature. First, make sure the motor air intake is not blocked. Also, ensure the control board is properly connected to the back plate and that conductive thermal paste is used on the power components.
