Firstly, I have a top notch plumber/electrician(combined) who has been installing the parts and trouble shooting the issues with our hot tub. In 2009 we had this hot tube fixed at your shop at a considerable cost and then it was mothballed until this fall when we connected it. Upon startup the circulation pump failed and we had it replaced. Upon re-start the flo2 error code was encountered so we purchased a new flow sensor from your shop a few days ago. Upon restart the unit functioned property for at least an hour(Almer the plumber/electrician monitored it for an hour and then departed), but when I returned home the flo2 error code had returned. If you could provide some insight into troubleshooting this issue it would be appreciated.
We live in Kenora so bringing the hot tub to Winnipeg is not an option and neither is having an aqua tech technican travel to Kenora.
We purchased this hot tub from Aqua Tech and have also had an inground pool installed by your shop
