Step 3 – Insert the robot into the Base Station and wait a few seconds. If the robot does not wake up, turn the System Switch to ‘Off’ and wait until the screen turns on with a message “U032”. Proceed to Step 4.

Step 4 – Is there a message “U032” on the screen?

If Yes – Let the battery be charged fully (it may take up to 24 hours) and observe if this happens again. If it happens again, contact the Robomow Hotline for further analysis. Note: Insert Power Box to pause mode by pressing the On/Off button for 3 seconds until red bulb is illuminated.

If No – The robot needs to be taken for repair to an Authorized Service Station.

Step 5 – Disconnect the Drive Unit (make sure the battery is connected). Does the robot come up?

If Yes – Connect the Drive Unit back and observe that the robot does not wake up. If this is the case, you will need to replace the Drive Unit.

If No – Connect the Drive Unit and disconnect the Mow motor. Observe that the robot does not wake up. If this is the case, you will need to replace the Mow Motor.

Step 3 – Is the fuse burnt?

If Yes – Replace the fuse and check if it burns immediately again (this is a fast acting 20A/32V fuse that can be found in local electricity shops). If the fuse gets burnt immediately again, check the fuse wires going to the safety/main switch to see if any part of the wire is browned/burnt. Check the fuse housing as well and smell it to find traces of being burnt. If burnt, Replace Fuse Housing and Battery Cable. The main switch is part of this cable.

If No – Insert the mower into the Base Station, turn the Safety Switch to Off, and wait a few seconds until the screen turns on with the message “Switch On”. Proceed to Step 4.

Step 4 – Is there a “Switch On” message on the screen?

If Yes – Wait 30 minutes to let it charge fully (it may take up to 24 hours). Then turn safety/main switch On and observe if this happens again. If it happens again, contact customer support.

If No – Remove the GSM.

Did removing the GSM help and mower now works fine?

If Yes – Replace the GSM and install a good new one. Test it and make sure it transmits.

If No – Proceed to Step 5.

Step 5 – Check the below parameters in the same order as written in the table. Once the root of the failure is found, stop checking the rest of the parameters, and replace the faulty part.
