Sylvan Gemini pool/spa saltwater pool. The plumbing has to be manually adjusted when switching which side you are heating or cleaning. This used to work great in all settings. Currently normal swim mode works and spa only seems a little weak. If I change to what is supposed to be pool clean the pump cannot stay primed and I believe the suction cleaner gets inconsistent pressure causing it to not work properly.
When the pool is in normal swim mode and filter pump are running as expected there is a sequence I am supposed to use when switching to pool clean. Even if I follow that the suction is good for about 30 seconds then starts getting air in system and the inconsistent pressure starts.
