Your spa should filter in low mode during your filter cycle in standard mode. If your jets or any button is pressed during filtration your cycle will pause and resume after the spa as been dormant for 40 mins. If you are seeing something different and have a Gecko system (placed in H2X models in 2023) you may want to review if you have warm weather mode enabled ( his can override the filter cycles if the spa senses it's getting too hot). If you would like further walkthroughs on your spa's settings you can call 1-800-860-7727 or email to support@masterspas.com.
