Why does my 2 priv say no atomizer even though I changed the tank?

Woke up and my vape kept saying no atomizer. I cleaned it and tried to changed the tank to see if it was the mod or the tank. It is the mod. I dont understand how that happened though? Is there a way to fix it? Looked everywhere and unfortunately there are no vape shops that do repairs near me….. could it be water damage? and if so how would i be able to tell. someone help:(
