Step-by-Step Solution
Inspect Boundary and Guide Wires
Walk the perimeter checking that boundary wire is intact with no cuts breaks or loose connections. Pay special attention to areas where wire crosses walkways or where it may have been damaged by landscaping.
Clean Charging Station and Mower Contacts
Turn off mower and clean charging contacts on both station and mower with dry cloth. Remove grass clippings dirt and corrosion. Ensure contacts are properly aligned and spring-loaded contacts move freely.
Verify Charging Station Placement
Confirm charging station is on level ground with adequate clearance (3 feet front 1.5 feet sides). Station should be positioned with guide wire creating clear straight path for mower to follow back to dock.

Use mower diagnostic mode or app to test guide wire signal strength. If signal weak check guide wire connections to charging station and verify wire has no breaks along its path to outer boundary.
Reset Navigation and Recalibrate
Perform mower reset according to manual then run auto-calibration sequence if available. This clears navigation memory and re-learns optimal docking approach path for your specific charging station setup.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Guide wire should run in straight line from charging station to boundary with minimal curves. Curves in guide wire can confuse mower navigation.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
