Possible Causes
Household circuit undervoltage, Loose power cord connection at smoker, Damaged internal power cord or terminal block, Failing low-voltage regulator on control board
How to Fix / Troubleshooting
Safety first: Unplug the smoker before inspecting the power inlet or internal wiring.
Steps to address E9:
- Check outlet and circuit: Plug a different high-load appliance (like a kettle) into the same outlet to confirm proper voltage and stability. Avoid using long or undersized extension cords.
- Inspect power cord: Examine the Landmann power cord for cuts, kinks, or burn marks. Replace if damaged.
- Check internal connections: Remove the rear or bottom panel to access the power inlet and terminal block. Tighten any loose screws and ensure spade connectors are fully seated.
- Look at the control board power section: If accessible, inspect the area where AC is converted to low voltage (transformer or switching supply). Burnt or bulging components indicate the board must be replaced.
- Test again: After securing connections, reassemble and test. If E9 persists on a known-good outlet, the control board is likely defective.
