2-speed

Hi. I have a hot tub with Balboa GS500Z and Wellis ACM0681 dual speed pump. When at high speed/jet it only runs for 2-3 minutes. (should run for 15 minutes) Anyone know what the problem could be?

We have a brandnew Hayward Powerflo Matrix 2 speed pump installed April 2020 by a professional electrician. Everything was working fine until yesterday when I noticed that the pump won’t work on High Speed. But it works on Low Speed. I’ve checked the pump basket and nothing is blocking it. No...
