Possible Causes

Failed main control board, Corrupted control firmware, Loose or oxidized control harness connections, Voltage surge damage

How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control panel or touching any wiring.

Step-by-step checks:

  • Power reset: Turn off the breaker or unplug the dryer for at least 5 minutes. Restore power and see if the error clears. This can reset minor control glitches.
  • Inspect control connections: Remove the control panel to access the main control board. Check all harness connectors for secure fit and signs of corrosion or heat damage. Reseat each connector one at a time.
  • Check for moisture or contamination: Look for signs of water intrusion, detergent residue, or insect damage on the board and connectors. Clean gently with electronics-safe cleaner if needed (with power disconnected and fully dry before reassembly).
  • Board inspection: Examine the control board for burnt components, cracked solder joints, or bulging capacitors. Any visible damage usually means the board must be replaced.

When to call a technician: Firmware issues and board-level diagnostics typically require specialized tools. If a reset and connector checks do not resolve E06, professional service is recommended.
