It's poosible that some of you spa jet nozzles are blocked inside the jets. If the jets are plastic....there should be a clip that holds them in. Once the clip is out....the jets can be inspected for debris. Some jets the clip doesn't come all the way out.....you just have to pry the end of the clip at the tab with a screwdriver while pulling out the jet. Also.....check that you don't have too many jets turned off.....that could be also causing the problem. Hope this helps. Check that first before removing any jets.
