husqvarna Automower 430xh/450xh
20 fault codes documented
Blade disc not rotating — No cutting action while product moves
The product moves around the work area but the blade disc, which performs the cutting, is not rotating. This is normal when the product is searching or reversing.
Blue flashing light — Boundary wire not connected or damaged
The indicator lamp on the charging station is flashing blue, indicating a problem with the boundary wire. This could mean the wire is not properly connected or there is a break in the loop.
Cutting height blocked — Adjustment mechanism obstructed
The mechanism for adjusting the cutting height is blocked by grass or other debris, or objects are stuck between the blade disc and the chassis.
Cutting system blocked — Blade disc obstructed or in water
The blade disc is unable to rotate freely due to obstructions or being submerged in water. This prevents the product from cutting grass effectively.
Difficulty docking — Product struggles to return to charging station
The product struggles to correctly dock itself into the charging station. This can be caused by improper installation of the guide wire or the charging station itself.
Green flashing light — Good signal, ECO mode enabled
The indicator lamp in the charging station shows a flashing green light. This means the signals are good and ECO mode is currently active, which is a normal operating condition.
Green solid light — Good signal, normal operation
The indicator lamp in the charging station shows a solid green light, indicating strong and correct signals. This is the normal operating state for the charging station.
Headlights flash — Product stopped due to a fault
The robotic mower's headlights are flashing. This indicates that the product has stopped operating because of an internal fault. This visual alert needs to be enabled in the product's settings.
Mowing and charging times shorter — Battery degradation
Both the amount of time the product mows and the time it takes to charge are shorter than normal. This usually points to a degraded or spent battery.
No loop signal — Boundary wire or power issue
The robotic mower cannot detect the boundary wire signal. This often indicates a power problem with the charging station or a break in the boundary wire. Check the charging station's LED status for more clues.
Parked for hours — Product remains in charging station without operating
The product stays in the charging station for an extended period without initiating its mowing schedule, indicating a potential setting issue or environmental factor.
Product vibrates — Imbalance in the cutting system
The product exhibits noticeable vibrations during operation, indicating an imbalance in the cutting system. This can affect cutting quality and mower longevity.
Red flashing light — Interference in charging station antenna
The indicator lamp in the charging station shows a red flashing light, suggesting interference with the charging station's antenna. This can disrupt communication with the product.
Red solid light — Error in circuit board or power supply
The indicator lamp in the charging station shows a solid red light, indicating a more serious internal error such as a fault with the circuit board or an incorrect power supply to the station.
Runs at wrong time — Mowing schedule or internal clock incorrect
The product is operating outside of the expected mowing schedule or at incorrect times, indicating a setting issue with its internal clock or schedule.
Shorter mowing periods — Reduced operation time per charge
The product's operational time between charges is shorter than expected, indicating potential issues with the battery or cutting efficiency due to obstructions or dull blades.
Trapped — Product blocked in a small area
The product is unable to move freely and is stuck in a confined space due to surrounding obstacles. It cannot navigate away from its current location.
Uneven mowing results — Inconsistent grass height or missed areas
The lawn does not have a consistent, even cut, showing patches of longer grass or areas that appear to be missed by the product.
Wheel motor blocked — Obstruction preventing wheel movement
The product's drive wheel is unable to move due to grass or other objects wrapped around it. This prevents the product from operating correctly.
Wrong PIN code — Incorrect PIN entered
An incorrect PIN code has been entered on the product's keypad. You are allowed 5 attempts before the product becomes temporarily blocked.
