Lanark spa bath. Air jets keep coming on and off all day and night.. No water in the tub. Air jets are not working when I'm in the bath. They stay on for a second only.

SOURCE: I have a new Pentair

difficult i know but all i would do here is to dismantle the pump and take it to specialist electric motor rewinder and ask them to have a look ,had quite a few problems like this of late and its down to made in china windings in the pumps ,they are nowhere near as good as a nice general electric made in the good old USA or a bosch or something made to a proper standard

SOURCE: I have a Lanark double

fill the tub with water and then turn the pump on. Get under the tub next to the pump and loosen the union on the discharge of the pump until some water starts coming out. If you have an air lock this will relief that and the pump should start pushing water to the jets.

SOURCE: hot tub jets won't come on. Backlight on topside works and shows current temp. but jets or led lights in tub won't work. Topside panel buttons are dead. What is problem? Viking Royale spa

This sounds like a back circuit board to us.
