Husqvarna Automower Error Code 3: How to Fix It

Q: What causes Husqvarna Automower Error 3?

Error 3 is caused by wrong loop signals, typically from electronic interference near the boundary wire or charging station, crossed wires, damaged boundary wire, or loose connections at the charging station.

Q: Can I still use my mower with Error 3?

No, Error 3 is a high-severity error that prevents safe operation. The mower cannot properly detect the boundary and may leave the designated area or operate unsafely.

Q: How do I find a break in my boundary wire?

Use a multimeter to test continuity across the wire loop. Start at the charging station and work in sections, testing resistance until you find an area with no continuity indicating a break.

Q: What electronic devices can interfere with my Automower?

LED landscape lighting, wireless routers, electric fences, pool equipment, sprinkler controllers, and other automated garden devices can all interfere with the boundary wire signal.

Q: How deep should I bury the boundary wire?

Boundary wire should be buried 1-4 inches deep. Shallow burial risks damage from garden tools, while deeper burial can weaken the signal strength to the mower.

Abstract

Husqvarna Automower Error 3 indicates a wrong loop signal, typically caused by interfering signals from nearby electronics or crossed boundary wires. This high-severity error prevents your mower from operating safely and requires immediate attention to restore normal function.
