Robot mower shows E14 and stops; often related to internal electronics overheating.

Safety first: Turn OFF main power and allow the mower to cool before further inspection.

• Cool‑down period: Move the mower to a shaded, well‑ventilated area and let it cool for at least 30 minutes. Do not cover it.
• Check vents: Inspect all ventilation slots and grills for grass, dust, or spider webs. Clean them with a soft brush or compressed air.
• Avoid midday heat: Adjust the mowing schedule so the mower runs in the early morning or evening when temperatures are lower.
• Inspect motors: If the mower feels unusually hot around the blade or wheel motors, check for mechanical drag (jammed blade, stiff wheels) and correct as needed.
• Persistent E14 in mild weather: The internal temperature sensor on the Main Control Board or a motor may be faulty. Have a technician test and replace the affected component.
