Max G2 Completely dead after using the accelerator but control panel lights up if manually pushing.

I’ve got a Max G2 and unfortunately I think there was some unexpected rain one night. I let the scooter sit for days and it drove normally but the motor in the rear sounded a bit louder than normal.

Today it died after hitting the accelerator. But I was able to get it on a few more time and also noticed the rear wheel would spin backwards for a second, but then go to the correct direction (had it lifted on a platform to see) but after hitting the accelerator again it completely died.

If I try and ride it like a manual razor scooter and get fast enough the control panel does come to life for a second or two but won’t stay on.

I did try disconnecting the handlebar wire and leaving it off for a few minutes, but that didn’t do anything.

Any suggestions? It’s only got 200 miles and I know right before it died. It was about 90% charged.
