What to do if Graco Water Pump dispenses incorrect amount of material?
If your Graco Water Pump isn't dispensing material correctly, several factors could be at play. First, ensure the tank ball valve is open. Next, check if the tank is empty and add fluid if needed. A clogged tank can also cause this issue, so clean it thoroughly. Finally, air in the material can disrupt dispensing; in this case, prime the machine.
Why is the material dispensed by my Graco Water Pump not the correct weight?
If the material dispensed by your Graco Water Pump isn't the correct weight, there are a few things to investigate. Start by recalibrating, running a 3-point calibration, as the specific gravity of the materials might have changed since the last calibration. Also, a malfunctioning check valve could be the culprit; remove it and clean or replace it if necessary. Lastly, a worn or broken piston can cause weight inaccuracies, so consider replacing the piston.
How to troubleshoot a completely dark display module on a Graco Water Pump?
If the display module on your Graco Water Pump is completely dark, begin by verifying that the AC power switch is turned on. If it is on, check the machine's breakers and reset them if necessary. A loose connection could also be the cause; tighten the 5-pin cable on the Advanced Display Module. If none of these steps work, the Advanced Display Module may be faulty and need replacement.
Why does my Graco Water Pump have high temperature overshoots?
If you're experiencing abnormal primary heat control with high temperature overshoots in your Graco Water Pump, start by examining the RTD connection to the long green plug on the heater control board. Unplug and re-plug the RTD wires, cleaning off any debris, and repeat for the long green connector. Ensure the RTD is contacting the heater element by loosening the ferrule nut, pushing in the RTD, and tightening the nut 1/4 turn past tight while holding the RTD tip against the heater element. Also, check the RTD connections and power up zones one at a time to verify temperature rise. If problems persist, a failed heater element may need replacement, or the RTD may be wired incorrectly, requiring a connection check.
What to do if Graco Water Pump hose heats slowly?
If the hose on your Graco Water Pump heats slower than usual or doesn't reach temperature, consider these factors. If the ambient temperature is too cold, use an auxiliary hose system. Check the FTS to ensure it hasn't failed or isn't installed incorrectly. Also, verify the line voltage, as low voltage significantly reduces the power available to the hose heat system.
Why is my Graco Water Pump leaking material from the pump seal?
If you observe significant material leaking from the pump seal of your Graco Water Pump, it's likely that the pump shaft and/or shaft seal are worn. Remove the pump shaft assembly and reinstall the pump rebuild kit.
What to do if Graco HFR Power Tool dispenses incorrect amount of material?
If you're not getting the right amount of material from your Graco Power Tool, here's what might be happening: * The ball valve might be closed. Make sure to open the tank ball valve. * The tank could be empty. Add more fluid. * There might be a clog in the tank. Try cleaning it out. * There could be air in the material. Prime the machine.
Why is Graco HFR dispensing material with incorrect weight?
If the material dispensed by your Graco Power Tool isn't the correct weight, consider these potential causes and solutions: 1. The specific gravity of the materials may have changed since the last calibration. Try running a calibration. 2. There might be a check valve malfunction. Remove the check valve and clean or replace it if needed. 3. A worn or broken piston could be the culprit. Replace the piston.
How to fix dark display module on Graco HFR?
If the display module on your Graco Power Tool is completely dark, here are a few things to check: * Make sure the AC power switch is turned ON. * Check the machine's breakers and reset them if necessary. * Ensure the 5-pin cable on the Advanced Display Module is tightened. * The Advanced Display Module might be bad and need replacement.
What to do if Graco HFR primary heat control is abnormal?
If the primary heat control on your Graco Power Tool is acting up with high temperature overshoots, here's what to investigate: * A dirty RTD connection could be the problem. Unplug and re-plug the RTD wires. * The RTD might not be contacting the heater element. Loosen the ferrule nut, push in the RTD so the tip contacts the heater element, and then tighten the ferrule nut 1/4 turn past tight while holding the RTD tip against the heater element. * The heater element might have failed and needs replacing. * There could be a signal failure from the RTD. Check the connections. * The RTD might be wired incorrectly. Check the connections, power up zones one at a time, and verify that the temperature for each zone rises.
