I just replaced my pump (Waterway Executive 4hp pump) on my Catalina Spa and fired it up. For some reason, the pump turns on for 10 seconds and the jets flow, but then it shuts off immediately. It remains idle for 2 minutes and then turns on again for 10 seconds. This cycle has been repeating endlessly as far as I can tell since installing the pump a couple days ago. Also, there are no error messages on the spa's readout display, only shows the temperature like normal. Any ideas?
