Welcome to our forum.
In your instruction manual it should explain how to clean a rotating jet. It tells you to submerge the jet in a bucket of water. Rotate the jets internal nozzle while you move it back and forth allowing water to flow through both ends. This motion allows water to wash through the jet bearings to dislodge debris. You are supposed to do this once or twice a year. This info came from a Sundance manual. Hope it helps. Sometimes I think a new one might be more of a solution.Scout
Keep in mind that those jets are waranteed for two years and if it keeps giving trouble after you clean it, have your dealer swap it for a new one.
. The warranties are broken down into sections much like a car if you will although I hate myself for using that sector as a comparative..
My dealer was gave us a bag of extra spinning jets,large and small. He said they were fairly inexpensive. But then again I own a Bahia and they don't use the chrome ones. We swap them around with the fixed jets, and what a difference that makes. Yes by all means do it when the tub is full. We find that because we had extras, some of them are much "looser spinning" than others. I told my dealer this and he said to bring back the sticky ones and he would swap them.
