UE MegaBoom speaker not working after being submerged in the pool?

My UE MegaBoom speaker is about four years old. It was accidently dropped in my pool, all the ports were closed. I had two other UE MegaBoom speakers partyup’d playing music, total of three UE MegaBoom speakers. The speaker that fell in the pool stopped working after about five minutes. Is there a repair shop out there that can repair it? Thank you
