Mammotion Intermittent Power / Reset Issue

Robot mower randomly reboots during operation without showing a specific error code

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose battery connector, Failing battery causing voltage dips, Loose mainboard power connector, Overheating mainboard regulator

Safety: Turn OFF the mower and disconnect the battery before inspecting connectors.

Battery plug: Ensure the battery connector is tight and fully engaged.
Mainboard power: Reseat the main power connector on the mainboard.
Thermal check: After a short run, carefully feel (without touching live circuits) for excessive heat near the mainboard regulators. Ensure vents are not blocked.
If reboots continue, test with a known-good battery pack. If still present, the mainboard may require replacement.
