Nordson® F1 Fault – Installing New Hose

You have just spent half an hour removing an old glue hose and installing a new one, powered up your Nordson® ProBlue® system and, BAM…..A F1 Fault Light. That bites! Fortunately, it is a quick and easy fix. 

This indicates there is a compromise in one of the electrical connections. In other words, one of the 2 connections is not fully plugged in.  Try these steps to resolve:

 • Power off melter.
 • Check both electrical connections on both ends of the hose.
 • Turn power on for melter and you should be good to go. 

If you are still having issues, call us for free technical support…..800-235-8090 or email at sales@keystoneparts.com
