The spa is half in the ground and half out with a custom tile enclosure. My first thought was perhaps a proper venting system obstruction but I could not see anything that seemed to be venting out, except for the access doors to the equipment. Also, it seems that the condensation is only on one side of the equipment "cabinet". I was not able to find a leak but the condensation is not only on the plumbing and motors/pumps but also seen on the overhead tiles as if everything is sweating. Is there an environment/humidity control unit for the interior of the "cabinet"? Perhaps some kind of blower?
thanks for your help.
