This shows you how to fix an E3 Error message on a F1 Cup Sealer machine . The Sensor on the BACK of the machine where the cup tray swings in and out is loose or not being pressed , which causes the reel not to spin or move, or even causing the heat plate to come down .
This needs to be re-adjusted , so that it is clicked. Perhaps that sensor was loose and needs to be re-adjusted. This will get rid of the E3 Error issue.
ALSO CHECK IF THERE ARE ANY LOOSE WIRES NOT PLUGGED INTO THE CIRCUIT BOARD .
Let us know if this fix the issue.
