Ez Cloner Mister Pump Making Noises?

When it fires up it makes a clunking sound like a bearing is loose or a piece of hydroton is stuck in there?

I've looked in there slightly but haven't seen anything to cause this.

Do these pumps go bad often? I don't know exactly how long it's been doing this.

Its a pump out of a 30 ex cloner.

How much is just a new pump?

You have a life time warranty on the 750 mag drive. They are over 100 bucks. Hope you can get it replaced. They are suppose to last forever. Only one moving part.

I would take it out and clean it up to see.
