  If there's no blast air flow and the water pump isn't cycling when the blast control is engaged on your Graco Power Tool, check a few things. First, ensure your air supply provides 100-125 psi; verify your air compressor setup if it doesn't. Next, make sure the Emergency Stop is disengaged. Finally, inspect the hose cable for damaged or shorted wiring in the electric blast control circuit, check the battery and control panel connections, confirm the DC power source is 12V, and check/replace the 3A fuse inside the control panel. If current exists, replace the relay.

What to do if the blast control is not engaged but blasting still occurs with Graco EcoQuip?

  If your Graco Power Tool is blasting even when the blast control isn't engaged, it could be due to a few reasons. The main air regulator might be stuck open. Also, the blast control tubing might not be connected properly, so ensure the air tubing is correctly routed and connected. Lastly, the electric blast control circuit could be malfunctioning, so inspect the hose cable for damaged or shorted wiring, check the battery and control panel connections, ensure the DC power source is 12V, and check the 3A fuse inside the control panel, replacing it if necessary. If current exists in the circuit, replace the relay.

Why is there no blast air flow when the blast control is engaged on my Graco EcoQuip, and the water pump cycles?

  If you're experiencing no blast air flow and the water pump cycles when the blast control is engaged on your Graco Power Tool, it might be due to the blast regulator not being adjusted to the correct pressure, so adjust the blast regulator to the desired pressure while the blast control is engaged. Another reason may be that the tubing to the main air regulator is not properly connected, so confirm that the tubing from the blast regulator to the main air regulator is intact. Also, the blast air regulator may be malfunctioning, in which case you should replace it.

Why won't the blast pressure reach the desired set point on my Graco EcoQuip?
- A
  Austin MejiaSep 5, 2025
  If the blast pressure on your Graco Power Tool isn't reaching the desired set point, there are a couple of potential causes. The air supply might be inadequate, so ensure the air inlet pressure gauge reads 100-125 psi; if it doesn't, check the air compressor for proper setup. Alternatively, the blast air regulator could be malfunctioning, in which case you should replace it.

What causes a strong hose recoil when engaging the blast control switch on the Graco EcoQuip Power Tool?

  A strong hose recoil when engaging the blast control switch on your Graco Power Tool can occur for a few reasons: 1. The unit might not be on a level surface, so place it on one. If that's not possible, ensure the Auto-Vent is on the higher side of the unit. 2. The initial pot pressure might not be set correctly, so confirm the auto-vent valve is working and set the initial pot pressure 30 psi above the blast pressure. 3. The Auto-Vent could be malfunctioning, so perform the auto-vent cleaning procedure. 4. The diaphragm may need to be flushed, so perform the diaphragm flush procedure. If flushing doesn't solve the problem, consider repairing the diaphragm valve.
