Robomow displays E6 and stops, often when turning or on slopes.

Safety first: Turn the mower OFF and remove it from the slope or obstacle area before inspection.

• Check wheels for obstructions: Inspect both drive wheels for stones, branches, or packed mud between the wheel and chassis. Remove any debris.
• Inspect lawn conditions: Verify the mower is not operating on slopes steeper than the model's rated maximum. Fill holes or ruts that can trap a wheel.
• Spin wheels by hand: With power OFF, lift one side at a time and rotate the wheel. It should turn smoothly with some gearbox resistance but no grinding or binding.
• Check wheel treads: Worn treads can cause slipping and overload. Replace the wheel if the tread is significantly worn.
• Reset and test: Place the mower on level ground, power ON, clear the error, and start a manual mow. Observe if one wheel hesitates or makes noise.
• If E6 recurs on one side: The corresponding drive motor/gearbox assembly may be failing and should be replaced as a unit.
