Display shows Er5 and grill will not run the auger or fan.

Safety first: Unplug the grill before inspecting wiring. Do not open the control board housing while it is connected to mains power.

• Step 1 – Check outlet: Plug a known‑good appliance or lamp into the same outlet to verify power. If the outlet is dead or intermittent, have it repaired before using the grill.
• Step 2 – Remove extension cords: Plug the grill directly into a grounded outlet. Long or thin extension cords can cause voltage drop and trigger Er5.
• Step 3 – Inspect power cord: Examine the Landmann power cord for cuts, crushed sections, or burn marks. Replace the cord if any damage is found.
• Step 4 – Verify power inlet and switch: If your model has a rocker power switch or IEC inlet, ensure the plug is fully seated and the switch is firmly in the ON position. Check for looseness or arcing marks.
• Step 5 – Internal inspection: With the grill unplugged, remove the control panel and inspect the internal power supply area for burnt components or loose connectors. Reseat all multi‑pin plugs.
• Step 6 – Board replacement: If Er5 persists with a known‑good outlet and cord, the internal power supply on the control board is likely faulty. Replace the control board or contact a qualified technician.
