The same happened to mine (I like to use it as a carb plug on my cleisen adapters on a bong).
I ran warm 100% iso through my until it flowed clear(this took quite a while to do adding a drip at a time to the oven), my unit was out of warranty and barely being used due to restriction so I thought what can I lose?
Mine works great again but you might not be as lucky, I also sat my unit in front of a fan to dry it out for afew hours and left it for a couple more days before trying it again.
