How to Fix / Troubleshooting

Safety first: Unplug the dryer before accessing the control panel.

Steps to inspect control system:

  • Verify power supply: Confirm correct voltage at the outlet and that the circuit breaker is not partially tripped.
  • Check harness connections: Remove the top panel and control panel cover. Inspect all connectors to the main control board for looseness or corrosion. Reseat each connector firmly.
  • Visual inspection of PCB: Look for burnt areas, swollen capacitors, or cracked solder joints, especially around relays and power components.
  • Reset: With power disconnected, leave the dryer off for 5–10 minutes, then reconnect and test. If E08 returns and no wiring issues are found, the control board is likely defective.

Replacement of the main control board involves handling static-sensitive electronics and high-voltage connections; if unsure, use a professional service.
