Mark,
Our website literature refers to the pump as a Bubble Blaster 2000. I double checked everything and did not find it referring to the Bubble Blaster 1000.
Regardless, how old is your skimmer and how old is the pump? If it is more than 3 years old, then it is out of warranty and you will need to purchase a new pump. Here is the link...

If the pump is less than 3 years old and you have proof of purchase, then please start a ticket using the "Submit a Ticket" link to we can start the warranty process.
