Robot mower shows E6 and stops near the boundary wire; may not detect the loop correctly.

Safety first: Unplug the charging station power supply from the mains before working on the boundary wire.

• Check charging station LEDs: On Parkside bases, a steady green LED usually indicates a healthy loop. A flashing or off LED suggests a boundary fault. Refer to your model's legend.
• Inspect boundary connections: Verify that both ends of the boundary wire are firmly clamped into the base station terminals and that there is no corrosion. Trim and re‑strip the wire ends if necessary.
• Walk the wire: Follow the perimeter wire around the garden looking for cuts, chew marks (from pets/rodents), or places where garden tools may have damaged it. Repair breaks using waterproof Parkside boundary wire connectors.
• Check for splices: Any previous joins are common failure points. Re‑make suspect joints with fresh gel‑filled connectors.
• Test loop resistance: With a multimeter, measure continuity between the two wire ends at the base (with the base disconnected). An open circuit indicates a break still present.

When to suspect the base: If the wire is continuous and correctly connected but the base LED still indicates a fault and E6 persists, the boundary transmitter board in the charging station may be defective.
