Possible fix for the Error 1 - LDS not working
Material:
Screwdriver
9V Battery
2 connectors
Disassemble the upper part until you get to the LDS, then unplug it, connect it to the 9V battery and let it run for a few minutes. Put it back and assemble the vacuum again.
Or you can use an external power source, using a USB cable and laptop / PC / power bank. It works perfectly fine after, you don't need to change it.
