Stiga Intermittent Power Loss or Loose Connection

Robot mower starts but stops after a few minutes without an error code and can be restarted again.

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, Intermittent main switch, Cracked solder joint on main board, Vibration‑sensitive wiring fault

Safety first: Turn OFF the mower and remove it from the lawn.

Check main switch: Toggle the main power switch several times. Ensure it clicks positively and is not loose.
Inspect battery plug: Open the battery compartment and reseat the battery connector firmly.
Wiggle test (advanced): With the mower ON and stationary, gently tap or wiggle the housing near the main board and battery. If it shuts down, a loose connection or cracked solder joint is likely.
Service: Board‑level repair for cracked joints should be done by a professional.
