6.5 Symptoms
If your robotic lawnmower does not work as expected, follow the symptoms guide below.
There is a FAQ (Frequently Asked Questions) on www.gardena.com which provides more detailed answers to a
number of standard questions. Contact GARDENA customer service if you still cannot find the reason for the fault.
Symptoms Cause Action
The robotic lawnmow-
er has difficulty dock-
ing.
The boundary wire is not laid in a long
straight line that is far enough out from the
charging station.
Check that the charging station has been in-
stalled according to the instructions in
Instal-
ling and connecting the charging station on
page 13
The guide wire is not inserted in the slot un-
der the charging station.
It is absolutely critical for operation that the
guide wire is perfectly straight and is in the
correct position under the charging station.
Therefore make sure that the guide wire is al-
ways in its slot in the charging station. See
Laying and connecting the guide wire on
page 19
.
The charging station is on a slope. Place the charging station on a surface that is
entirely level. See
Best charging station loca-
tion on page 11
.
The robotic lawnmow-
er runs at the wrong
time
The robotic lawnmower clock needs to be set. Set the clock. See
Time & Date on page 28
.
The start and stop times for mowing are in-
correct.
Reset the start time and stop time settings for
mowing. See
Advanced on page 23
.
The robotic lawnmow-
er vibrates.
Damaged blades lead to imbalance in the
cutting system.
Inspect the blades and screws and replace
them if necessary. See
To replace the blades
on page 39
.
Too many blades in the same position lead to
imbalance in the cutting system.
Check that only one blade is fitted at each
screw.
Different versions (thickness) of GARDENA
blades are used.
Check if the blades are of different versions.
The robotic lawnmow-
er runs, but the blade
disc does not rotate.
The robotic lawnmower searches for the
charging station.
No action. The blade disc does not rotate
when the robotic lawnmower is searching for
the charging station.
The robotic lawnmow-
er mows for shorter
periods than usual
between charges.
Grass or other foreign object blocks the blade
disc.
Remove and clean the blade disc. See
Clean
the robotic lawnmower on page 38
.
The battery is spent. Replace the battery. See
Battery on page 39
.
Both the mowing and
charging times are
shorter than usual.
The battery is spent. Replace the battery. See
Battery on page 39
.
The robotic lawnmow-
er is parked for hours
in the charging sta-
tion.
The robotic lawnmower has an inbuilt standby
period according to the Standby time table.
See
Standby on page 36
.
No action.
The STOP button has been activated. Open the hatch, enter the PIN code and con-
firm with the OK button. Press the Start but-
