    How to fix no adhesive coming from Nordson Melting Machines?
    • J
      Jonathan WilliamsAug 2, 2025
      If your Nordson Melting Machine isn't dispensing adhesive, start by checking if the melter tank is empty and fill it if necessary. Ensure the melter motor is switched on. Also, verify the melter pump is functioning correctly. Other potential causes include the application head not reaching operating temperature (wait until it does, and check the temperature setting), a clogged nozzle (clean it), or a stuck nozzle stem (replace the control module). Furthermore, make sure the control air is connected. If the application head is cold, refer to the section addressing heating issues. If the solenoid valves aren't switching, consult the relevant section for troubleshooting those.

      Christine GeorgeAug 8, 2025
      If the application head on your Nordson Melting Machine isn't heating, first ensure the temperature is set correctly on the temperature controller. Check that the power plug is securely connected. If the problem persists, disconnect the unit from the line voltage and inspect the fuses in the melter; replace them if they are defective. A faulty heater cartridge in the application head could also be the cause, so consider replacing it.

    Why is the application pattern not exact on Nordson EP 30 Melting Machines?
    • C
      cruztiffanyAug 14, 2025
      If the application pattern from your Nordson Melting Machine isn't exact, begin by ensuring the temperature is precisely set on both the melter and the application head. Verify that the adhesive quantity and pressure are also set accurately. Check the distance between the nozzle and the substrate, ensuring it's correct. Confirm that the control unit for the solenoid valves is programmed correctly. Clean the nozzle if it's polluted inside or outside, or replace it if damaged. Ensure the application quantity and substrate processing speed are properly attuned. If the adhesive is unsuitable, consult the manufacturer.

    What to do if solenoid valves do not switch in Nordson Melting Machines?
    • K
      Kathryn JordanAug 21, 2025
      If the solenoid valves on your Nordson Melting Machine aren't switching, first ensure that the control unit is switched on. Then, check that the connecting plug is properly plugged in and tight. A loose connection can prevent the valves from switching correctly; ensure a secure fit.

    Why application head does not reach the set temperature in Nordson EP 30?
    • D
      Dr. Jessica CowanAug 27, 2025
      If the application head on your Nordson Melting Machine isn't reaching the set temperature, the heater cartridge(s) in the application head may be defective and require replacement. Another possible cause is a low ambient temperature; raising the ambient temperature may resolve the issue.
