Attached Spa jets aren't turning on

Spa Attached to Pool. When I turn on the spa the pumps pressure jumps from 20 (pool circulation) to 30. Most times the jets fail to start going, water is coming out but at normal speed not jet speed. Oddly I have found if splash water out of the spa the jets eventually turn on. Any ideas on what the issue might be and why lowering the water would have any impact? Filter is brand new. Thanks!

This could be related to the water flowing through the jets are backing up and causing a restriction. Your system will need to be inspected to find the cause of back pressure, and it is normal for you filter pressure to rise when a variable speed pump is increased in speed.

Thanks for the reply! Can you provide more information on back pressure causes? It's odd because sometimes the jets work just fine with the spa water level normal and others I have to lower the height of the water to get them going. Where would I start to look for back pressure? back at the pump? The pool has an automation system that controls the valves, is it possible there is an issue with a valve? There is no issue with the pool when it's circulating, all of the cleaners and sprayers work fine without issue.
