Possible Causes

Dust bin not installed, Robot not on floor (lifted), Child lock enabled in app, Faulty start button or keypad PCB

How to Fix / Troubleshooting

Safety: Keep the robot on a flat floor while testing.

  • Check bin and covers: Ensure the dust bin is fully inserted and any top covers are closed properly.
  • Disable child lock: Open the AEG app and verify that any child lock or key lock feature is turned off.
  • Use app start: Try starting a cleaning cycle from the app to rule out a faulty physical button.
  • Reset robot: Perform a soft reset (power cycle) or factory reset if necessary.
  • If it still won’t start: The keypad / control panel PCB or mainboard input circuit may be defective and require replacement.
