Philips Mg7950/15 Wet And Dry Shaver Started Malfunctioning After Shower Usage

I bought the Philips Mg7950/15 wet and dry shaving set on July 22, 2024. I noticed that it was used but I didn't care. It may have come from a return. I used it 3 times and there was no problem. However, I used it for the first time in the shower on September 8. After I was done, I separated the machine and its accessories, washed it and laid it on a towel to dry. After 5 minutes, the machine started working by itself. I can't stop it in any way. Water probably leaked inside and it is short-circuiting. I love the Philips brand very much but this situation disappointed me. The wet and dry model leaked water in the shower. I am very angry with the brand, I will try to return it.
