What Ron is getting at is you may need to clean Calcium deposits out of the inside of the venturi - the part that introduces air to the pump
I had a problem with mine last year and found it takes too long to effectively clean it out quickly, so I bought a spare for my Skimz and keep one soaking in vinegar all week. Then I scrub it out with a jewellers flathead screwdriver before use
I clean my skimmer weekly and swap the venturis everytime
