I have an Older (99 I Believe) Hot Springs Grandee, It has Worked Fine Since Installed April this year, but over the Last 2 nights Has only the Red Power Light Flashing. If I Set and Reset the 2 Breakers (20 And 30 Amp) On the Side of the House then Walk to the Front of the Tub, the power light will Stop Flashing and the Display is Illuminated showing the set temp (Also if I Lean near the Tub it Sounds like the Circulation pump is running) but within a Couple of Minutes the Display will stop being illuminated with the set temp and the Red Power light will start to flash. What can Cause the Power light to Flash (Dirty Filters, Bad Circ Pump, Thermistors)? Is there a Best Sequence to try and Isolate the Cause of the Flashing Power Light? FYI (I have a Fluke 87 and know my way around a meter so can test resistance and voltages easily to Speed Diagnosis) Any Hints or Tips Greatly Appreciated!

Serial number is different from what I am familiar with. Is this an export tub to canada or Europe? I Believe it is a USA Made Spa, Just purchased it here in the USA (Missouri 30 Miles South of St Louis to be Specific). I think it May be a 1998 or 1999. FYI it Has the Digital Control Panel and IQ2000 Controller, and older Fiber optic Based Topside Controls. Please click on the Links below to See Pics of the SN Label and Grandee SPA.
