Possible Causes

Loose communication cable, Damaged display panel, Faulty main control PCB, Incorrect wiring after service

How to Fix / Troubleshooting

Safety: Disconnect power before removing the front panel or accessing electronics.

  • Check low-voltage harness: Inspect the cable between the main control board and the front display/keyboard module. Ensure both ends are fully seated and not damaged.
  • Look for moisture: Check for signs of condensation or water ingress on the control board and display. Dry gently if minor moisture is present; if boards are wet, they may need replacement.
  • Power cycle: Restore power and perform a full power cycle (off for 30 seconds, then on) to reset communication.

If E14 persists, either the display module or main PCB is likely defective and should be replaced by a Kospel service technician.
