Segway Navimow i105E error 6105 — Out of boundary error

Likely cause or condition

• Mower is outside the mapped boundary / positioning state incorrect

Also note whether the message appeared after a collision, a map or app change, poor weather, maintenance, charging, or work near the affected lawn area. That timing helps separate a temporary operating condition from a repeatable mower, station or installation fault.

Step-by-step diagnosis

1. Step 1. Place on open flat ground inside boundary or dock, press STOP, wait for normal status and resume.
2. Step 2. Record whether the mower is physically outside the mapped area or only reports that condition.
3. Step 3. Move the mower only after pressing STOP and following the manufacturer handling procedure.
4. Step 4. Check the nearby virtual boundary for recent edits, narrow gaps, obstacles or positioning shadows.
5. Step 5. Place the mower on open, level ground well inside the mapped area before clearing the message.
6. Step 6. Observe the mower status light and positioning state before starting a new task.
7. Step 7. Test whether the event repeats in one location or follows the mower around the lawn.
8. Step 8. Do not redraw the whole map until local obstacles and positioning conditions have been checked.
9. Step 9. Escalate if the mower cannot recognise a clearly open position inside the saved boundary.

After each safe action, write down whether the code cleared, returned immediately, or returned only at a particular place. Stop the test if the mower, battery, cable or charger shows heat, damage, water ingress, burning smell or abnormal noise.

How to interpret the result

• The code clears and stays cleared: complete a short supervised mowing test. Recheck the same area or operating condition before considering the fault resolved.
• The code returns in one location: investigate the lawn, map, passage, signal environment or installation at that location before blaming mower hardware.
• The code returns everywhere: preserve the exact code, time, app screenshots and actions already completed. That evidence gives an authorised technician a cleaner starting point.
• The official first action cannot be completed: stop. Do not improvise around safety systems, sealed electronics or damaged lithium batteries.

Safety limits

Stop the mower and follow the manufacturer shutdown/isolation procedure before touching blades, wheels, charging contacts or internal components.

Never bypass a safety switch, work on powered charging equipment, or open a swollen, hot, leaking or damaged lithium battery. Manufacturer instructions for the exact mower take priority over general guidance. Use an authorised dealer whenever a procedure requires internal electrical testing, sealed-unit access or battery work.

Keep a useful fault record

Save the mower model, serial number, code, date, weather, lawn location, status lights and each completed check in Mower Passport. If the error returns, this history can show whether it is seasonal, location-specific, related to charging, or becoming more frequent. It also prevents the same checks being repeated during a service visit.
