Symptoms
- Mower wanders near the dock but doesn't connect
- Mower stops or gets stuck before reaching the dock
- App shows a docking error or timeout
- Worked fine before but has become inconsistent
Likely causes
- CommonBoundary wire signal weak near the dockA break, splice, or interference near the perimeter wire close to the dock confuses the homing signal.
- CommonDocking station not level or positioned per specMost docks need a specific clear approach distance and level ground to guide the mower in reliably.
- PossibleCharging contacts dirtyDirt or corrosion on the mower's or dock's charging pins can prevent a successful connection even if it reaches the dock.
- PossibleMetal or interference near the dockNearby metal objects or other wireless signals can disrupt the low-power homing signal.
What to do
- Check the app or mower manual for the required clear approach zone in front of the dock and remove any obstacles.
- Confirm the dock sits level and firmly anchored, since a tilted or loose dock can misalign the charging pins.
- Inspect the charging contacts on both the mower and dock, cleaning off dirt or corrosion with a dry cloth.
- Walk the boundary wire near the dock looking for visible breaks, loose splices, or crossed wires.
- Move any large metal objects or other wireless equipment away from the dock area if possible.
- Run the mower's built-in docking or diagnostic test, if available, to isolate the issue further.
Tools and parts
- Dry cloth
- Wire splice connectors (if needed)

When to call a pro
If docking issues continue after checking placement and the wire, the manufacturer's support or an installer can test the signal system.
