Scooter turn off automatically HELLP!

Guys this evening I went out riding my jupiter 110 and on returning home my scooter got off by itself,it happened 3 times.

It happened when i slowed down like in traffic and slowed when a car came in front of me.

It happens when I slow down ,

I am guessing it might be because I washed my scooter this morning. 😭😭

Help anyone knows about it.

My scooter had it's first service on June it's alright.

Until this happened i think because I washed it.
