# MOVA LiDAX error messages: what each alert means and the fix

MOVA LiDAX robot mowers show errors as text messages in the MOVA app, not number codes. MOVA's manuals for the LiDAX Ultra, LiDAX Ultra AWD and LiDAX Pro 800 list 40 of them with a fix for each, and all 40 are here.

## Short answer

MOVA LiDAX mowers show errors as written messages in the MOVA app, such as Robot trapped, Blade disc can't rotate or Failed to dock in the charging station. Most fixes are physical: clear the obstacle, clean the wheels, blade disc, LiDAR or camera, then restart. Safety stops like Robot lifted, Robot tilted and Emergency stop is activated must be unlocked on the mower: enter the PIN on the LiDAX Ultra and AWD models, or press OK twice on the LiDAX Pro 800. If a message survives cleaning and a restart, contact MOVA after-sales service.

| Error message | What it means | Fix from MOVA |
|---|---|---|
| The robot is not connected to the app | The MOVA app cannot reach the mower | Check the robot has finished starting up and the router works, then move closer to connect over Bluetooth |
| Failed to connect to Wi-Fi | The mower cannot join your network, usually because it is 5 GHz | Use a 2.4 GHz network. The mower does not support 5 GHz |

| The robot is in the station but does not charge | The battery is too hot or too cold to charge (AWD and Pro 800) | Let the battery cool or warm up into range, then charge again |
| LiDAR is blocked | Something covers the LiDAR | Remove the LiDAR protective cover. If the LiDAR is very dirty, clean it with a lint free cloth |
| LiDAR malfunction | The LiDAR is very dirty or has a sensor error | Clean the LiDAR if it is dirty and try again, then restart the robot |
| LiDAR is dirty | Dirt on the LiDAR sensor | Wipe the LiDAR with a clean cloth and keep it dry |
| LiDAR temperature is high | The LiDAR is overheating and will stop soon | The robot returns to the station to cool. Run it below 40 °C and park it in shade. It resumes on its own |
| LiDAR temperature is too high | The LiDAR has stopped because it is too hot | Move the robot to a shaded, ventilated spot and run it below 40 °C |
| Robot is lost | The mower has lost its position | Clean the LiDAR, move the robot to an open place in the map, or drive it back to the station in the app |
| Sensor error | A sensor fault | Restart the robot and try again |
| The robot is in the no-go zone | The mower is inside a no-go zone | Move the robot out by hand or with remote control in the app, then try again |
| The robot is outside the map | The mower is outside the mapped area | Move the robot back inside the map by hand or with remote control in the app, then try again |
| Emergency stop is activated | The Stop button was pressed | Enter the PIN on the robot and confirm (Pro 800: press OK twice) |

## How MOVA LiDAX error messages work

MOVA does not use number codes in its LiDAX manuals. When the mower stops, the MOVA app shows a short message, and each manual has a troubleshooting table with the cause and the fix.

The three manuals share most messages, but not all. The LiDAX Ultra uses Battery temperature too high, is high and is low. The LiDAX Ultra AWD and Pro 800 instead say The robot shuts down on the spot, The robot pauses tasks and auto-returns to the station, or The robot is in the station but does not charge. The AWD models also show Drive wheels error in place of Left/right rear wheel error, and add The robot vibrates abnormally while mowing.

## The general fix sequence

MOVA's fixes follow the same order for most messages. Work through it before you contact support.

- Clear the physical cause: remove obstacles, move the mower to an open, flat spot inside the map, or clear the station.

- Clean the part named in the message: wheels, blade disc, LiDAR, front camera or charging contacts.

- For safety stops, unlock the mower on the robot: enter the PIN on the LiDAX Ultra and AWD, or press OK twice on the Pro 800.

- Restart the mower.

- If the message keeps coming back, contact MOVA after-sales service.

## Limits that differ by model

Several fixes depend on the model's limits. The tallest object the mower can cross is 4 cm (1.6 in) on the LiDAX Ultra and Pro 800, and 6 cm (2.4 in) on the AWD. The steepest slope is 45% (24 degrees) on the LiDAX Ultra and Pro 800, and 80% (38.7 degrees) on the AWD. MOVA says to cut grass taller than 10 cm (3.9 in) first on the LiDAX Ultra, and taller than 12 cm (4.7 in) on the AWD and Pro 800.

For heat, MOVA's advice on every model is to run the mower when the air is below 40 °C (104 °F) and to park it in the shade.
