Possible Causes
Grass too tall or wet causing overload, Blade jammed by rope, wire, or branch, Dull or bent blade increasing load, Faulty blade motor or motor bearings
How to Fix / Troubleshooting
Safety first: Turn the main power switch OFF and remove the mower from the lawn. Wait until the blade has completely stopped. Wear gloves before touching the blade.
- Inspect for obstructions: Carefully turn the mower on its side (battery side up as per manual). Check around the blade for wrapped wire, toys, branches, or heavy grass clumps. Remove all debris.
- Check blade condition: Look for a bent, cracked, or heavily worn blade. A damaged blade can overload the motor. Replace the blade if any damage is visible.
- Spin test: With power OFF, gently rotate the blade by hand. It should turn smoothly without grinding or tight spots. If it feels stiff, the blade motor bearings may be failing.
- Adjust mowing schedule: If the grass is very tall or wet, first cut it with a conventional mower, then resume Robomow operation with more frequent cycles to reduce load.
- Reset and test: Return the mower upright, power ON, clear the error, and start a short manual mow in a light‑load area.
- Persistent E5: If the error returns quickly with no obstruction, the blade motor or motor driver on the main board may be defective. Professional diagnosis and replacement are recommended.
