I have a swift river spa bought from lowes 6 years ago. it's been a great spa and i've read tons of great advice from this forum for many years. It's time i join the forum and ask for help!
My spa's topside is throwing a code: PS1. The owners manual says
"the system checks for a closed pressure/flow switch with the low speed pump or high speed pump active. if an error is detected the heater will be deactivated, this code with reset if fixed within 2 1/2 minutes, if not a manual restart is required. This may be caused by dirty filters, try cleaning filters before calling technician."
The filters were cleaned, no success
the flow switch was replaced, no success
the circ pump was replaced, no success
the manufacturer now says i need to buy a control pack ($400) but they're the ones that said I need a flow switch and then the circ pump. So I come to you.
Does anyone know of any reasons the system would detect a closed flow switch?
-the code pops up before i ever turn on a pump, and the manual says it detects "while the pump is active"
-after a manual reboot the circ pump comes on immediately and the code does not pop up until the circ pump stops.
-The code pops up after a minute without a pump ever being "active" but if I turn on a pump the code pops up faster.
-sometimes (rarely) the circ pump will never stop and the code will not pop up untill i turn a pump on.
I'm just trying to see if there's a little thing i'm missing before i spend 400 on a control pack (and hope it works)
Thanks you for your time everyone!!!
