I have a 90's vintage calspa that I replaced the controller on this summer. I bought an ACC ePACK digital controller from Spa Babes. After installing everything worked fine for the next 2 months. The water level dropped about 4"to 5" due to a leak (now fixed) I believe this is when the low pressure PSoL error started. If refilled the tub to the right level and still had the error I powered off everything and it came back with the same error. I tred bleeding the system as described in the manual but my pump will not turn on to circulate while I loosen the pipe going to the controller. I try adjusting the pressure switch from min to max with no chage.

I drained the tub, reseated the connections on the pump (240 V 2-stage). I filled the tub and it started working. Brought the tub up to temp and used it one night. Two days later it had the PSoL error again. I have just taken out the filter and cycled the powere with the same error, PSoL. I adjusted the pressure switch again but there was no change and I cannot get the pump to circulate.

Assuming you have a quick fix and it works how do you adjust the pressure switch?
Thanks, Zoomer
