E8 error appears; cooker powers on but none of the cooking programs will start.

Safety first: Unplug the unit before removing any panels. Capacitors on the control board may retain charge briefly after unplugging.

Step-by-step checks:

• 1. Power reset: Unplug the multicooker for at least 10 minutes to allow internal electronics to discharge. Plug back in and test again.
• 2. Check outlet and cord: Verify the wall outlet has correct voltage and that the Saturn power cord and plug are not damaged or overheated.
• 3. Inspect control panel connection: Remove the top or front panel (depending on model) to access the display/control PCB. Ensure the ribbon cable between the keypad/display and main board is fully seated.
• 4. Look for burn marks: Examine the main PCB for burnt components, cracked solder joints, or bulging capacitors in the power supply section.
• 5. Surge protection: If E8 appeared after a power surge or outage, the board may be permanently damaged and require replacement.

Recommendation: Control board repair typically requires electronic troubleshooting and soldering. In most cases, replacing the entire main PCB with a genuine Saturn spare part is the practical solution.
