Dryer displays E09 and will not start or stops abruptly; often associated with power or control issues.

Safety first: Unplug the dryer and verify the outlet voltage with a meter before suspecting internal faults.

E09 generally indicates a serious control or power problem.

• Check power supply: Verify the wall outlet provides the correct voltage (e.g., 220–240 V AC in many regions). Inspect the plug and cord for damage or overheating.
• Inspect internal wiring: Remove the top panel and inspect the main harness connections to the control board. Look for burned connectors, loose plugs, or signs of moisture damage.
• Examine the control board: With the board exposed, look for burnt spots, swollen capacitors, or cracked solder joints. Any visible damage usually means the board must be replaced.
• Reset attempt: After checking connections, leave the dryer unplugged for 5–10 minutes, then reconnect and try again. If E09 returns immediately, the control board is likely defective.
• Board replacement: Label and photograph all connectors before removing the board. Transfer any removable wiring harnesses carefully. If you are not comfortable working with electronics, contact a professional technician.
