9 Troubleshooting
In this chapter, a number of messages are listed which may be shown in the display if there is a malfunction. There
is a proposal as to the cause and steps to take for each message. This chapter also presents some symptoms that
can guide you if the robotic lawnmower does not work as expected. More suggestions for steps to take in the event of
malfunction or symptoms can be found on www.gardena.com.
9.1 Fault messages
Below a number of messages are listed which may be shown in the display of the robotic lawnmower. Contact
GARDENA Central Service if the same message appears often. See MEMO on page 2.
Message Cause Action
Wheel motor blocked,
left
Grass or other object has wrapped

Check the drive wheel and remove the grass
or other object.
Wheel motor blocked,
right
Grass or other object has wrapped
around the drive wheel.
Cutting system
blocked
Grass or other object has wrapped
around the blade disc.
The blade disc lies in a pool of water.
Move the robotic lawnmower and if possible
prevent the collection of water in the working
area.
No loop signal
The power supply is not connected.
Check the wall socket connection and whether
an earth-fault breaker has tripped.
The low voltage cable is damaged
or not connected.
Check that the low voltage cable is not
damaged. Check that it is also properly
connected to the charging station and to the
power supply.
The boundary wire is not connected
to the charging station
Check that the boundary wire connectors are
tted properly to the charging station. See 3.5
Connecting the boundary wire on page 27.
Boundary wire broken.
Find out where the break is, see 9.5 Finding
breaks in the loop wire on page 75. Replace
the damaged section of the loop with a new
loop wire and splice using an original coupler.
ECO mode is activated and the
robotic lawnmower has attempted
to start outside the charging station.
Place the robotic lawnmower in the charging
station, press the START button and close the
hatch. See 6.8 Settings on page 56.
The boundary wire is laid in the
wrong direction around an island.
Check that the boundary wire has been laid
according to the instructions. See 3 Installation
on page 15.
The connection between the robotic
lawnmower and the charging station
has been broken.
Place the robotic lawnmower in the charging
station and generate a new loop signal,
see 6.4 Security on page 47.
Disturbances from metal objects
(fences, reinforcement steel) or
buried cables close by.
Try moving the boundary wire.
