I THINK I'M AT A BAD POINT . THE TUB ,WHEN I FIRST TURN THE BREAKERS ON IS NOW FLASHING RED , NOT HEATING FOR A TIME AND WHEN I TEST VOLTAGE TO THE CIRCULATING PUMP IT FLUCTUATES AND IS NOT STEADY . IF THAT IS THE BOARD I CANT AFFORD TO REPLACE IT. SO I WILL DRAIN THE TUB . THANKS FOR ALL YOUR SUGGESTIONS

I THE TURNED BREAKERS ON AND THIS TIME IT DIDN'T TAKE LONG FOR THE RED LIGHT TO FLASH. THE LITTLE LED GREEN LIGHT STAYED ON . THE BOARD , ITS TOOOO SMALL FOR ME BUT MY WIFE THINKS IT SAYS D 10 AND RIGHT TO THE RIGHT OF IT IT SAYS R 4. THE RED LED TO THE LEFT OF IT WAS ON MOMENTARILY BUT WENT OUT.IT IS LABELED D 9

SORRY I DIDN'T GET BACK FOR A COUPLE DAYS.. IT'S WOOD CUTTING TIME HERE IN MICHIGAN . I DRILLED OUT THE FARREL THEN LET IT RUN WITH BREAKERS ON AND FLASHING RED LIGHT CAME ON. THE CIRCULATION PUMP RUNS ALL THE TIME ANYWAY . PUMP DOESN'T GET HOT ,JUST WARM AND SO I DRAINED THE WATER DOWN SO I COULD SEE WHAT THE PUMP WAS DOING . IT HAD GOOD PRESSURE AND SQUIRTS ALL THE WAY ACROSS THE FILTER COMPARTMENT SO I KNOW THERE IS NO RESTRICTIONS IN FLOW COULD SOMETHING BE IN THE NO FAULT HEATER ? PROBABLY CLEAN IT LIKE THE ON DEMAND WATER HEATERS IN YOUR HOUSE WITH APPLE CIDER VINEGAR . LOOKS LIKE I CAN TAKE THE END OFF THE HEATER AND JUST FILL THE TUBES AND LET IT SET OVERNIGHT.

I HAVE BEEN THINKING AND WHAT RDSPAGUY SAID ABOUT THE CIRCULATION PUMP AND I MAY HAVE FOUND THE PROBLEM . A FEW MONTHS AGO WHEN CLEANING OUT THE LINES BECAUSE THE FLOOR RETURN WAS PARTIALLY PLUGGED I BROKE THE SMALL TIP THAT GOES FROM THE ELL ABOVE THE CIRCULATION PUMP UP TO THE FILTER AREA.(EVERYTHING IS BRITTLE.) I COULDN'T FIND A REPLACEMENT ELL AND WHEN I DID I HAD TO ADAPT IT BECAUSE IT WOULDN'T FIT THE TUBING. SINCE I HAD TO USE FARRELL'S TO ADAPT I AM WONDERING IF THE INSIDE OF THE FARRELL'S ARE TO SMALL AND RESTRICTING THE FLOW OF WATER ,JUST WONDERING . DOES ANYONE KNOW WHERE I CAN FIND THE RIGHT ELL WITH THE RIGHT TIP ON IT THAT FITS MY PLASTIC TUBING THE OTHER THING IS IT IS A HOT SPRINGS 2002 NOT 3

OK IT SET FOR A COUPLE DAYS AND I TESTED IT ON THE LEADS FROM THE THERMISTORS UNPLUGGED FROM BOARD. THE OUTLET THERMISTOR LEAD MEASURED 10.58 THE INLET THERMISTOR LEAD MEASURED 10.44 PLUGGED IN THERMISTORS AND TURNED ON THE BREAKERS AND IT HEATED FOR ABOUT 1 HR. THEN WENT INTO THE FLASHING RED LIGHT MODE. IMMEDIATELY SHUT BREAKERS OFF AND UNPLUGGED THE LEADS FROM THE BOARD THE OUTLET THERMISTOR LEAD MEASURED 8.34 THE INLET THERMISTOR LEAD MEASURED 87.5

BOTH BOARDS ARE REMARKABLE CLEAN ON THE BACK SIDE.

YES THAT IS THE LEADS I'M TALKING ABOUT . AND I TESTED IT THAT WAY ,THE WAY YOU JUST SAID . THE READINGS ARE WHAT I POSTED IN MY LAST POST WHAT ARE THEY SUPPOSED TO READ OR BE? I CAN'T READ THE SCHEMATIC PRINT IS TOOOO SMALL EVEN WITH A MAGNIFYING GLASS. I'M 82 , HAVE REALLY POOR EYESIGHT

THANKS FOR YOUR QUICK RESPONSE 1 I SET OHMMETER TO 20k 2 GOT A 8.20 READING ON THE INLET LEAD WITHOUT BEING PLUGGED ONTO THE BOARD 3 GOT A 8.28 READING ON THE OUTLET LEAD WITHOUT BEING PLUGGED INTO THE BOARD STEP 2 1 WITH BREAKERS ON AND BOTH LEADS PLUGGED INTO THE BOARD AND RED LIGHT FLASHING . 2 OHM METER SET AT 20V 3 2.41V AT INLET, PLUGGED INTO THE BOARD 4 2.40V AT OUTLET, PLUGGED ONTO THE BOARD NOTE I HAVE NO CLUE AS TO HOW TO TEST THE THERMISTORS. I COULDN'T FIND ANYTHING WITH A VIDEO ON YOUTUBE , JUST ON TESTING THERMISTORS , MAYBE SOMEBODY SHOULD DO IT.

THE RED LIGHT IS FLASHING ON A 2003 HOT SPRINGS GRANDEE 1 FLUSHED OUT ALL LINES AND HAVE GOOD FLOW PUMPS ALL WORKING UNTIL IT GOES TO RED LIGHT FLASHING. 2 CIRCULATION PUMP IS WORKING AND NO AIR LOCKS 3 RUN WITHOUT FILTERS TO CHECK THEM WITH SAME RESULTS ,THEY ARE CLEAN AND PUT BACK IN 4 HEATER WORKS GOOD FOR ABOUT 30 MIN. THEN GOES BACK TO RED LIGHT FLASHING AND NOTHING WORKS EXCEPT CIRCULATION PUMP 5 AFTER RED LIGHT FLASHES I HAVE TO SHUT OFF BREAKERS AND WAIT FOR A HOUR OR MORE TO RESET THE BREAKERS OR THE TUB WILL STILL FLASHES RED SO IT IS NOT WATER FLOW . WHAT NEXT? . WEAK PARTS ON BOARD?
