Possible Causes

Loose ribbon cable between display and main board, Failed LCD/touchscreen module, Faulty HMI communication driver on control board, Moisture ingress into front panel

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before removing the front panel or display assembly.

Steps to troubleshoot:

  • Visual inspection: Check the front display for cracks, condensation, or signs of impact.
  • Reseat connectors: With the enclosure open and power OFF, gently reseat the ribbon cable or harness connecting the display to the main control board.
  • Check for corrosion: Look for green/white corrosion on the display connector pins, indicating moisture damage.
  • Test after reseating: Restore power and see if the display initializes without E17.

If the fault persists, either the display module or the HMI interface on the main control board is defective. Replace the display assembly first; if unresolved, replace the main control board.
