We have a 2019 HydroPool swim Spa that we’ve owned for about two months. It is installed indoors. There are three pumps, one of the two main swim jets is not working. The other two work fine. It does not make a sound. We’ve done all the troubleshooting such as topping off the water, checking for any air leaks, rinsing the filter, no debris in skimmer basket. We confirmed electricity to the pump. Not sure what else to do. On the main screen intermittently it will detect the flow problem and give a warning message to check all the above things. The one thing we don’t know how to check is pump blockage. Any ideas?
