I had this problem once a loooooooong time ago with a 248 that was at my previous place of employment. If I remember correctly, my issue was caused by a set screw on the drive gear that had worked itself loose. My issue was stright forward and quickly repaired. Hope you're just as lucky!

Squeegee error on a 248 is strictly that sensor (reed SW) on corresponding (Front / rear) squeegee cylinder is not seeing a change in state... Either a physical obstruction preventing cylinder from exending fully - OR- if it is extending fully, then sensor or wiring of sensor feedback failure.

Most likely it is a faulty cable in the e-chain . You can test it in diagnostic: lower the back squeege and manually move back and forth for its entire travel the print carriage while monitoring the sensor output of the squeege. You will see at some point of the travel that the squeege sensor output changes its state.
