F1 Cup Sealer E3/E4 Error Message Fix

This video here will show you how to fix the issue for an E3 or E4 Cup Sealing machine error. This is for the F1 Cup Sealer Model. To fix this , MAKE SURE THE MACHINE IS OFF AND UNPLUGGED TO AVOID ANY SHORTAGES ON THE UNIT ITSELF. Open the back of the machine with the 4x screws holding it in place. Once removed, you will see a sensor on the back. You can do one of two thing. 1. The sensor is not functioning or being read by the machine. What you can do first , is locate the sensor and CLICK THE SENSOR 20-30x times consecutively. This will ensure that the sensor is working and may allow that sensor to reset. Do this step first to see if this will resolve the issue. 2. Make sure that the sensor is touching and being clicked. If the machine operates and does NOT click this sensor, more than likely, it is not sending signal to the rest of the machine to perform the next step. Whether being sealing the cup, exposing the tray, lifting the heating plate, etc. The problem lies where this sensor is too FAR and is not being clicked to send the signal. Using the screws to remove the sensor will allow you to re-configure the position so it is being clicked. This will more than likely resolve the issue.
