Troubleshooting - Husqvarna Automower 420 Technical Manual

6 Troubleshooting

The troubleshooting section consists of 2 main areas:
1. Messages
2. Symptom
Each message and symptom is explained using one or more possible causes of the problem, followed by
one or more solutions.
First go through the basic and installation-related possible causes described in the following sections in this
chapter. Before further troubleshooting and component replacement is carried out, also perform the following
actions:
1. Update the main program and the HMI program to the latest version. Many problems are solved
immediately by the new software. When the robotic lawnmower is connected to Autocheck EXP, the
Assistant notifies if a newer software version is available.
2. Reset user settings in the mower by selecting Settings -> Reset user settings, enter the PIN code
and press OK or from Autocheck EXP: Tools -> Reset user settings.
Only if none of the above steps solve the problem, continued troubleshooting should be carried out and any
components replaced.
