Guide not found
Gardena Guide not found on robot mower: guide wire not detected
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
The SILENO cannot detect the guide wire it follows back to the charging station. Gardena gives three causes: the wire is not connected to the station, it is damaged, or it is not joined to the boundary loop. Check the station lamp and the splice before suspecting a fault.
Safety first
Stop and check this first
- Gardena says to disconnect the charging station from the power outlet before you work on the guide wire or its splice with the boundary loop.
Safe checks you can perform
- Check the colour of the station lamp
- Inspect the G connector on the station
- Walk the guide wire to the splice

What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Wire break location by GARDENA service
What they doIf the guide wire is properly connected and the lamp still flashes yellow, GARDENA service can locate a buried break that is not visible.
They must show youthe exact point where the break was found and the method used to find it.
In writingthe length of wire replaced, the couplers used and the final price of the job.
Charging station check if the lamp makes no sense
What they doA solid red lamp on the station means a circuit board or power supply fault that, according to the manual, GARDENA service must correct.
They must show youa station test with the guide wire connected and the resulting lamp colour.
In writingthe fault found, the part replaced and the repair warranty.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check the colour of the station lamp
- Who:
- you, next to the charging station.
- How:
- look at the indicator: Gardena says a flashing yellow light means the guide wire is not connected to the station or is damaged, while solid or flashing green indicates a correct installation.
- Result that matters:
- confirming whether the station sees a problem in the guide wire circuit.
- If the lamp flashes yellow:
- the fault lies in the guide wire or its connection, so carry on with the checks below.
- If the lamp is green:
- the wire looks fine and it is worth repeating the guide calibration from the menu.
- Evidence to keep:
- a dated photo of the station lamp.

Inspect the G connector on the station
- Who:
- you, with the mower off and the station unplugged from the outlet.
- How:
- push STOP, set the mower to OFF by holding ON/OFF for three seconds and take it out of the station. Disconnect the station from the power outlet and make sure the guide wire connector is pressed on and seated on the pin marked G, with the wire routed through the slot in the plate.
- Result that matters:
- a firm connector on the right pin with no visible corrosion.
- If it was loose or on another pin:
- fit it correctly, plug the station back in and check that the lamp turns green.
- If the connector was fine:
- follow the wire to the splice with the loop.
- Evidence to keep:
- a photo of the connector and the pin before and after the check.

Walk the guide wire to the splice
- Who:
- you, following the wire carefully without pulling on it.
- How:
- trace the wire from the station to the point where it joins the boundary loop. Look for cuts, freshly dug areas and the splice coupler: Gardena wants the wire ends visible through the transparent part and does not accept twinned wires or taped screw terminals.
- Result that matters:
- finding a cut or a bad splice that explains the message.
- If you find a damaged section:
- replace it with new guide wire and original couplers.
- If you see nothing wrong:
- ask service to help locate a hidden break.
- Evidence to keep:
- photos of the splice and of any suspect section, with its position in the garden.

What it means
In the information message table of the SILENO city and SILENO life operator's manual (page 40), "Guide not found" has three causes: the guide wire is not connected to the charging station, the guide wire is damaged, or it is not connected to the boundary loop. The actions are to connect it, replace the damaged section, or join it correctly to the loop. It is an information message and on its own does not prove that the mower or the station has a faulty part.

Symptoms and causes
Probable causes · in order
- Guide wire loose at the stationCommon
The guide wire connector belongs on the metal pin marked G on the charging station; if it comes off, the mower stops receiving the guide signal.
Evidence: Gardena SILENO city and SILENO life operator's manual 2023 (1298-022)
- Damaged section of guide wirePossible
A spade, stones shifting with ground frost or mowing too low just after installation can break the wire or its insulation weeks later.
Evidence: Gardena SILENO city and SILENO life operator's manual 2023 (1298-022)
- Guide wire not spliced to the boundary loopPossible
The end of the guide wire must be joined to the boundary wire with a properly pressed original coupler; a weak or taped joint oxidizes over time.
