Battery Voltage Too Low means the pack is too deeply discharged for normal startup. Seat the mower precisely on the powered base, leave it undisturbed for emergency charging, and verify battery percentage rises. Long storage, failure to reach the base, dirty contacts, station power loss, cold, battery aging, or charging faults can deeply discharge it.

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

E7 means charging is paused because the battery is too hot or cold, or the mower cannot read it normally. Move the mower and base out of extreme sun or cold, let the pack normalize naturally, then restart and redock it. Direct sun, freezing weather, trapped heat, charging after a hard run, poor communication, or

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
