6 Troubleshooting
6.1 Introduction - 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.
6.2 Fault messages
Below a number of fault messages are listed which may be shown in the display of the robotic lawnmower. Contact
your local GARDENA representative if the same message appears often.
Message
Cause
Action
Wheel motor blocked,
left
Grass or other object has wrapped around
the drive wheel.
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.
Check the drive wheel and remove the grass
or other object.
Cutting system
blocked
Grass or other object has wrapped around
the blade disc.
Check the drive wheel and remove the grass
or other object.
The blade disc lies in a pool of water.
Move the robotic lawnmower and prevent the
collection of water in the working area.
No loop signal
The power supply is not connected.
Check the wall socket connection and wheth-
er an earth-fault breaker has tripped or not.
Check that the low voltage cable is connected
to the charging station.
The low voltage cable is damaged or not con-
nected.
Check that the low voltage cable is not dam-
aged. Check that it is also properly connected
to the charging station and to the power sup-
ply.
The boundary wire is not connected to the
charging station.
Check that the boundary wire connectors are
fitted properly to the charging station. Re-
place connectors if damaged. See
ing the boundary wire on page 18.
Boundary wire broken.
Find out where the break is. Replace the
damaged section of the loop with a new loop
wire and splice using an original coupler. See
Find breaks in the loop wire on page 48.
ECO mode is activated and the robotic lawn-
mower 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
Settings on page 29.
The boundary wire is crossed on its way to
and from an island.
Check that the boundary wire is laid accord-
ing to instructions, e.g. in the right direction
Installation on page
26.
The connection between the robotic lawn-
mower and the charging station has been
broken.
Place the robotic lawnmower in the charging
station and generate a new loop signal, see
New loop signal on page 26.
Disturbances from metal objects (fences, re-
inforcement steel) or buried cables close by.
Try moving the boundary wire.
Trapped
The robotic lawnmower has got caught in
something.
Free the robotic lawnmower and rectify the
reason for it becoming trapped.
The robotic lawnmower is stuck behind a
number of obstacles.
Check if there are any obstacles which make
it hard for the robotic lawnmower to move on
from this location.
