Good Morning: I have Arctic Coyote Hot Tub - Bandit that has had a new 2 speed pump installed in June 2015. Last night noticed that the water was not strong coming out of jets. When pressing the power button (only 1 button to push) the power should go the high speed so that water is rushing out the jets. It does not. Venturi dial also does not do anything. The only thing that works is the slow recirculating and the heater light is flashing. We emptied the hot tub, put hose down the filter, replaced the disposal filter, and plugged it back in. Still no strong power. It just sounds like it is having a hard time pushing the water through, with no change of speed.

Any ideas? Is it a malfunctioning pump?
