When starting the machine or during operation the GUI displays a “Pump Valve Error”


This problem is most likely caused by improper clean-out of the valve assembly or inadequate system warm-up time. Product residue can cause the torque required to turn the valve to become excessive.


The following steps should be taken to correct the pump errors.

  1. From the GUI enable the chamber heater.

  2. Bring the chamber heater to temp, and allow to sit for 30 minutes.

  3. Re-Initialize the pump from the GUI pump control, located under the video feed.

  4. Proceed with normal operations.


To prevent this problem, ensure that the system is consistently cleaned after each use with 99% isopropyl alcohol, and that the valve assembly is not permitted to cool-down with product still inside.

Further Solutions

If the above steps do not clear the error, try heating the valve assembly with a heat-gun until it is a consistent 75c and restart the machine.
