cplarsen Posted September 18, 2007 Report Share Posted September 18, 2007 Have a used 1998 Arena that I just installed. Pumps run for a while, then shut off, and I get the "OH" on the display. Temp is still exactly where set when system resets. I suspect the pump/motor itself is either overheating or the temp probe on the heater is tripping it due to the pump/motor not running. Anyone have any ideas or troubleshooting tips? Quote Link to comment Share on other sites More sharing options...
cplarsen Posted September 19, 2007 Author Report Share Posted September 19, 2007 Ok, think I have it narrowed down to the circulation pump. Quote Link to comment Share on other sites More sharing options...
ce99 Posted September 21, 2007 Report Share Posted September 21, 2007 Ok, think I have it narrowed down to the circulation pump. how old is your D1? I'm pretty sure they have 5 year Warrenty. I just purchased a D1 Nautilus 2 months ago and love it. Let me know what the problem was. Good to stay in tune with other D1 spa owners.
