Perimeter wire not detected
Bosch Indego perimeter wire not detected on a robot mower
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On the Indego S/S+ 500 and M/M+ 700, the mower is not receiving the perimeter wire signal. Bosch points to no power at the docking station, a damaged or cut wire, wrong installation or interference: first check that the docking station LED is on.
Safety first
Stop and check this first
- Before working on the docking station or the power supply, Bosch says to remove the plug from the mains. Do not open the power supply: if the docking station does not start, take it to a Bosch Service Centre.

What a technician must be able to justify
Technician visit
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 signal measurement
What they doThe technician uses the Wire signal function in the Tools menu, which Bosch describes as being for the Service Agent, to read the signal strength and find the problem section.
They must show youthe signal strength before and after the repair.
In writingthe cause found, the section repaired and any parts replaced.
Docking station check
What they doIf the docking station does not start with the power supply connected, the Bosch Service Centre checks the docking station and its power supply.
They must show youthe docking station on with a green LED and the mower detecting the wire.
In writingthe docking station diagnosis and any part replaced.

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.
Docking station LED
- Who:
- you, without opening the power supply.
- How:
- look at the docking station LED: it should be on; if it flashes, Bosch says the wire is interrupted, the wrong length or not connected while the mower is outside the docking station.
- Result that matters:
- knowing whether the docking station has power and sees the wire loop.
- If it is off:
- check that the plug is connected; if the docking station does not start, contact your Bosch Service Centre.
- If it flashes:
- check the wire, then switch the power supply off and on again, as the manual says.
- Evidence to keep:
- photo or video of the docking station LED and of the message on the display.

Walk the perimeter wire
- Who:
- you, walking along the edge of the lawn.
- How:
- walk the wire looking for cuts, loose sections or pegs more than 75 cm apart; if you find a cut, Bosch says to repair it with the wire connectors and make the wire taut.
- Result that matters:
- finding a cut or a loose section that explains the lost signal.
- If there is a cut:
- join it with the Bosch wire connectors following the Installation Guide.
- If you see no damage:
- go on to check for interference near the docking station.
- Evidence to keep:
- photo of the cut and of the repair.

Excess wire and wire ID
- Who:
- you, from the mower menu.
- How:
- remove any excess wire coiled up near the docking station and, if the message stays, change the wire ID under Settings > Advanced > Wire ID, as Bosch suggests for interference.
- Result that matters:
- the mower detecting the wire again without interference.
- If the message clears:
- keep the new ID and note the change.
- If the wire is still not detected:
- ask a Bosch Service Centre to check it.
- Evidence to keep:
- photo of the menu showing the chosen wire ID.

What it means
The troubleshooting table in the Bosch Indego S/S+ 500 and M/M+ 700 original instructions (F 016 L94 038) lists 'Perimeter wire not detected' with four causes: no power at the docking station, a damaged or cut perimeter wire, wrong installation (for example not enough distance between wires) and the wire being close to a source of interference. If the docking station LED flashes, the wire is interrupted, too long or too short (it must be 20 to 350 m) or not connected. Other Indego models may show different messages, and the message alone does not prove that a part is faulty.

Symptoms and causes
Probable causes · in order
- No power at the docking stationCommon
Bosch says to check that the docking station is powered up with its LED on; without power there is no signal in the perimeter wire.
Evidence: Bosch Indego S/S+ 500 y M/M+ 700 instrucciones originales F 016 L94 038
- Perimeter wire damaged or cutCommon
A cut in the wire interrupts the signal; the manual links repeated cuts to a wire that is not taut or pegs more than 75 cm apart.
Evidence: Bosch Indego S/S+ 500 y M/M+ 700 instrucciones originales F 016 L94 038
- Wrong length or installationPossible
The wire must be 20 to 350 m long and perimeter wire runs must be at least 75 cm apart, following the Installation Guide.
Evidence: Bosch Indego S/S+ 500 y M/M+ 700 instrucciones originales F 016 L94 038
- Interference near the docking stationPossible
Excess wire coiled up near the docking station or a nearby source of interference; Bosch says to remove the excess and change the wire ID in the menu.
