PSoL and PSoH

[bluepokenut]

I have these trouble codes on my hot tub. I bought the control pack from Hot Tub Works if that helps.

PSoL is an error code for the pressure switch and PSoH is an error code for overheating. Since you are experiencing both that leads me to believe you may be having a water flow issue. So the first thing you should do is remove the spa filter (http://www.hottubworks.com/HotTubSpaFilters/Filter_Search.php) and turn on jets (http://www.hottubworks.com/SpaParts/JetsLanding.php) to see if the error codes clear. If they do you should replace the filter with a new one. The old filter may have been restricting the flow of water through the heater (http://www.hottubworks.com/SpaParts/HeatersLanding.php) causing both error codes.
