This article contains the following sections:
Q1 - Are there wheels excavation signs on the lawn?
If Yes – Proceed to Q2.
If No – Proceed to Q3.
Q2 - Does the path on the lawn enable smooth maneuvaribility? (holes, up/down hill, mud, high grass). See the table below for corrective actions:
If Yes – Proceed to Q3.
If No – Fix the path and check if it resolved the issue. If the error happens again right after the robot slips a bit (due to mud), increase the Slippage Sensitivity by 1 segment.
Service > P238. Proceed to Q3
Q3 - Can the front wheel be rotated freely on its axle and against the robot’s chassis?
If Yes – Proceed to Q4.
If No – Try to release the wheel (there may be debris, mud, or mulches that prevented the wheel’s ability to rotate freely).
If this cannot be released, the robot needs to be taken to an Authorized Service Station for repair
Q4 - Send the robot to work inside the lawn, where it has at least 5 meters to drive forward without hitting an obstacle or reaching a wire.
Will the robot drive straight for more than 2 meters without changing direction?
If Yes – Proceed to Q5.
If No – Open the Behavior screen (Service --> P126) and observe value #2 ‘Last Termination Event’. The table below describes the values that can be seen. Record the value seen while the robot is working, and act in accordance the findings.
Working with Special Display:
Once the desired Special Display menu has been selected, press the button to toggle between user menus and the Special Display screen that was selected. Send the robot to work in Scan mode by pressing
the button and then again press the
button to toggle back to the ‘Behavior’ screen, while the robot mows for observation.
Check value #2 (upper line, second value from the left). While the robot changes direction in a place which it should not change (in the middle of the lawn), observe value #2 shown on the screen and look for its number in the below table. Check the number in the table below.

When Will it Happen? |
What to Do Next? |
|
0 |
None |
No detection. |
Nothing. |
|
4 |
Distance |
This will happen when the robot drives forward 250 meters without reaching a wire, or hits an obstacle (bumper event). |
Check with the customer that the robot’s model is suitable for the size of the lawn. |
|
6 |
Wire |
The robot detects a wire. |
Check with the customer if a wire is indeed in that place, or if it was a false detection. |
|
7 |
Bumper |
The robot detects a Bumper. |
Check with the customer if indeed the robot hit an obstacle, or if it was a false detection. |
|
8 |
Front Wheel Dropoff |
The robot detects a Front Wheel Dropoff event. |
Check with the customer if indeed the robot is stuck in a place where the Front Wheel fell into a hole in the lawn. |
|
9 |
Front Wheel Slippage |
The robot detects a Front Wheel Slippage event. |
Check with the customer if the Front Wheel is rotating freely on its axle and against the robot’s chassis.
|
|
10 |
Drive over current |
This will happen if one of the Drive Wheels is facing a high current. |
Observe there is no visible reason for the Drive Wheel to rotate in friction. If nothing was found, run a Drive Test and act according to the test results. |
|
11 |
Slope |
When the robot drives in a slope of more than 20°, or 35%. |
Robomow is not designed to work on a surface with more than 20 degree slopes. |
|
12 |
Robot stuck |
While mowing, when the robot reaches the wire, it stops and drives back onto the lawn. If the robot fails to return back onto the lawn, it will stop with this error. |
Check the below: 1. Wire is fastened properly into the ground. 2. Make sure the perimeter wire is installed on a flat surface (not more than 6°, or 10%). |
|
13 |
End of Edge |
when robot completes the edge operation for any reason |
|
|
14 |
Lost the wire |
This will happen when the robot loses the wire signal. Make sure the main power was always on. |
If there was no power break, the robot, the Power Box, and the Base Station need to be taken to an Authorized Service Station for further analysis. |
|
15 |
Docking station detection |
The robot detects a Base Station nearby. |
Check with the customer if indeed a Base Station is located within a radius of 2 meters. |
Q5 - Run the robot and observe it for about 30 minutes. Did you notice any odd behavior while it was working? (changed direction in the middle of the lawn, stopped driving forward with no visible reason, etc.)
If Yes – The robot needs to be taken to an Authorized Service Station for further analysis.
If No – Let the robot continue to work and if this error happens again, contact the Hotline for further analysis.
Q1 - Are there wheels excavation signs on the lawn?
If Yes – Proceed to Q2.
If No – Proceed to Q3.
Q2 - Does the path on the lawn enable smooth maneuvaribility? (holes, up/down hill, mud, high grass). See the table below for corrective actions:
If Yes – Proceed to Q3.
If No – Fix the path and check if it resolved the issue. If the error happens again right after the robot slips a bit (due to mud), increase the Slippage Sensitivity by 1 segment. Go to Service > Settings > Slippage > Sensitivity.
Proceed to Q3.
Q3 - Can the front wheel be rotated freely on its axle and against the robot’s chassis?
If Yes – Proceed to Q4.
If No – Try to release the wheel (there may be debris, mud, or mulches that prevented the wheel’s ability to rotate freely).
If this cannot be released, the robot needs to be taken to an Authorized Service Station for repair.
Q4 -Send the robot to work inside the lawn, where it has at least 5 meters to drive forward without hitting an obstacle or reaching a wire.
Will the robot drive straight more than 2 meters without changing direction?
If Yes – Proceed to Q5.
If No – Open the Behavior screen menu: Service > P122
(Service > Information > Special Display > Behavior screen) and observe value #2, ‘Last Termination Event’. The below table describes the values that can be seen. Record the value seen while the robot is working, and act in accordance with the findings.
Working with Special Display:
Once the desired Special Display menu has been selected, press the button to toggle between user menus and the special display screen that was selected. Send the robot to work in Scan mode (skip the Edge), and again press the
button to toggle back to the ‘Behavior’ screen, while the robot mows for observation.
Check value #2 (upper line, second value from the left). While the robot changes direction in a place which it should not change (middle of the lawn), observe value #2 shown on the screen and look for its number in the table below. Check the number in the table below.
