Problem with pumps turning on randomly

I have an in ground gunite saltwater pool with the pentair easy touch remote control box inside the house. Lately it has been turning the hot tub jets on by itself at random days and times. This morning I was woken by my child informing me the hot tub was empty and spraying water in the air. The hot tub jet light was on again and the hot tub was 2/3 drained and the jets were spraying. (This isn't the first time that has happened.) Unlike before, simply pressing the button was not working and I had to go outside to turn it off poolside. Does anyone have a suggestion as to what is causing the jets to turn on randomly and at other times, it drains itself while the jets are going?
