Possible Causes

Loose communication cable between user interface and main control board, Damaged display PCB, Faulty main control PCB, Water ingress into control compartment

How to Fix / Troubleshooting

Safety: Turn off power at the breaker before opening the control panel.

Steps:

  • Inspect communication cable: Open the front panel of the Fairland heater and locate the low-voltage cable between the display (HMI) and the main PCB. Reseat both ends.
  • Check for moisture: Look for condensation or water marks inside the control box. Dry gently with a cloth and allow the unit to air dry before re-energizing.
  • Check for damage: Examine the cable for pinches or cuts, especially where it passes through metal openings.

Next steps:

  • If E08 persists, either the display PCB or the main control PCB may be defective. A technician should test and replace the faulty board.
