Really depends on oxidizer levels and sanitizer levels that you add before you close the lid. These chems. need to gas off before you close the lid 15-20 min.. If you do not add anything before the cycle - should be fine. Also, close your air controls so the jets dont't create extra gas off. Closing the lid after adding sanitizer or oxidizer can also burn your cover and break down the poly protecting your foam cores. Paddy

How old is the spa? Plastic in the pump means something broke. Maybe a valve or diverter? Paddy

Hey, I have worked on a few Arctics. The spas have a "check valve" that diverts water to certain jets when you turn that big dial (diverter valve). If the flapper inside the valve breaks chunks of plastic show up and the pump flow reduces due to the fact that the flow is now distributed to all the jets at once instead of just certain "zones" of jets. An arctic dealer should know of this problem, and the process needed for repair. Hope this helps. Let me know. Paddy
