Hi all. Hoping someone can point me in the right direction before I take this spa to the tip. I have a Hot Springs Vanguard spa (Australian/NZ) model. Not sure of the year it is as the model number doesn't seem to match anything. V29996? I purchased it second hand 2 years ago and it has always worked until now. It now has a flashing green light and the spa is not heating properly. What I have tried so far. Removed the main filter, Replaced the Hi limit thermister and control thermister I have checked the flow and there are plenty of O2 bubbles and water flow coming into the spa Also to note the external control panel (the one you access from in the spa) has never worked and the MOTO-MASSAGE jets have never worked I am not sure what I should be looking at next to replace. Has anyone has this issue before and fixed it?

I have a picture I can PM if needed I have a 2003 Caldera Aspire. Past November the original Heater Control Relay Board finally went out. I replaced with the updated Heater Relay Board (part #77119). Everything worked great, then suddenly about 2 weeks ago... No Heat. BUT a reset of the breakers, Heat would come back on for a few days then QUIT. Figured it was the filter, so took it out and cleaned... heat stopped during the middle of the night and has never come back on regardless of breaker resetting durations or times. WHAT DOES FLASHING RED LIGHT STAND FOR??? ON MAIN BOARD: LIM ON = GREEN - good ON MAIN BOARD: HTR = RED - good (works as it should with temp settings set) ON HEAT CONTROL BOARD RED LED #D9 = FLASHING RED - bad ON HEAT CONTROL BOARD GREED LED #D10 = GREEN - good (power from breaker for heater okay) I have tested power from the breakers, all 3 breakers GOOD (main panel and 2 in panel near tub) all power from breaker getting to tub as it should 240V Ground is good, Neutral is good tested the HI LOW (overheat sensor) using OHM meter, also hooked to tub put sensor in ice water and again in super hot water... tub cuts all power both hot and cold as it should tested the PRESSURE SENSOR when circulation pump is disconnected with OHM Meter, pressure sensor brakes contact and no power goes thru... with circulation pump on, contact made, power goes thru. (tested connections) adjusted pressure sensor, to see if any difference.. no difference, put adjustments back to stock checked for OHMs on heater, was good (do not remember exact number) checked all connections on both boards - all seems good Removed Heater Control Board - no burning, no ion smell, no signs of any issues, re-installed and double checked to make sure little pins were aligned properly, and double checked all wires after reinstalling Still NO power to the heater AND AFTER ALL OF THIS, THAT D9 LED RED FLASHING LIGHT KEEPS FLASHING what does it signify? please help? I have googled, and forum searched, but can not find answer. I am starting to believe I am going to have to buy another heater relay board...
