Tried to operate in service mode yesterday, but pump would not operate. Reset button on Intellitouch control panel panel then started flashing. Reset the button, but still the pump will not function. Interior IS4 control panel operates with no problem when in Auto mode. The same night, used the spa and noticed the spa light flashing off and on and then the IS4 spa sde remote quit functioning all together. The IS4 interior control panel indicated the error code of IS4 #1. I was able to reset the interior control panel, but obviously there is an issue. The situation leads me to believe that the Intellitouch control panel and the IS4 symptom are related. The Intelliflow pump (when circulating to water to the pool) works just fine in Auto mode. Only in Service mode or Auto Spa mode is where I have the problem. Any ideas/suggestions?
