Robot mower stops and displays E2, often shortly after starting or when turning.

Safety first: Switch OFF the main power and keep the mower upright when inspecting. Avoid working on steep slopes.

Steps to check:

• Check slope: Verify that the area where E2 occurs is within the Worx Landroid's maximum slope rating (typically around 20–35% depending on model). Move the charging base if it is on a slope.
• Remove hang‑ups: Inspect for roots, edging stones, or holes that cause one wheel to drop or lift. Fill holes and smooth transitions around patios and paths.
• Clean undercarriage: Turn the mower on its side (power OFF) and remove built‑up grass around wheels and chassis that could cause uneven support.
• Inspect tilt sensor connection: Open the top cover and locate the tilt sensor module (often a small board or sensor fixed to the chassis). Ensure its connector to the main PCB is firmly seated.
• Reset: Reassemble, place the mower on flat ground, power ON, and start a test run. Observe if E2 reappears only on certain slopes.

When to call a technician: Persistent E2 on level ground suggests a faulty tilt sensor or main board that should be replaced by a service center.
