E9 Mower Locked is an anti-theft or connectivity lock state on supported Landroid models. Restore the configured Wi-Fi, bring the mower into range, confirm it is online in the owning account, and allow the cloud state to refresh. A router change, new credentials, extended outage, weak coverage, account mismatch, or app failure can trigger the

E5 Mower Lifted is a safety stop indicating that the mower detected a lift condition. Place it on flat lawn, remove anything supporting the body or wheels, clean accessible moving areas, and restart without bypassing the sensor. Roots, holes, edging, toys, branches, packed debris, stiff body movement, or a lift-sensor fault can cause E5. The

E4 Mower Trapped appears when Landroid cannot move away from a location despite repeated attempts. Power off, move it to firm level lawn, inspect wheels and underside, then correct the exact trap point. Ruts, soft soil, roots, gravel, low obstacles, narrow gaps, packed wheels, or boundary geometry can trap it. The mower should leave the

E3 Blade Motor Fault means the cutting motor or blade disc could not operate normally. Power off fully, follow battery guidance, wear gloves, and inspect for packed grass, string, sticks, damaged blades, or resistance. Packed grass, wrapped string, trapped objects, bent blades, bearing resistance, damaged wiring, or a control fault may trigger E3. The disc

E1 Outside Working Area means Landroid detects a loop signal but believes it is on the wrong side of it. Place the mower well inside the loop, verify terminal direction, inspect crossed wire and islands, and try a short simple test loop. Reversed connections, crossed wire, incorrectly wired islands, weak signal, interference, or a mower

E1 Wire Missing means a wired Landroid cannot detect a usable boundary-loop signal. The break may be in the wire, a connector, the base power supply, or the mower’s signal detection. Quick answer: Check the charging base light and power first, then test the boundary loop with a short known-good wire. Repair outdoor connections only
