E01 low liquid alarm error code on JULABO circulators

In this “Question Mark at Home” video, Mark Diener, JULABO USA’s senior product manager, demonstrates what to do if you get an E01 error code on your JULABO circulator. The E01 error code signifies a low liquid level using an audible alarm and a flashing E01 error code on the circulator’s display. All JULABO circulators have a float switch inside the tank to detect liquid levels. If you turn the unit on immediately without filling the tank with fluid, you’ll get this error code and alarm. You can silence the alarm by pressing the OK button. To fully clear the alarm, turn off the circulator, fill the tank with fluid, and turn the circulator back on, now you’re ready to go. If you have any questions about this error code or any of our alarms and safety features, please call or send us a direct message.
