B&D Cordless lawn mower economically repairable?

[CLSteve]

My CM2040 stopped working. I finished 3/4 of my lawn. I stopped and it wouldn’t start again. Only 3 years old. Any troubleshooting tips. Can these be repaired?

I suspect this has a brushless motor. These have a lot of electronics to power and control the motor and are highly stressed. One component goes south and it's done. Pretty expensive mower and most reviews are basically negative. Ouch.

I'm unfamiliar with it, but on some Greenworks models there have been 'electro-mechanical' problems with safety devices and loose 'deadman bail' cables, etc.
Search Youtube too, occasionally good videos of troubleshooting stuff.
