  1. The ready light flashing is the temp thermistor. It is either no good, unplugged or plugged into board wrong.
  2. If you have a cover lifter from Hotspring that screws into aluminum plates that are inside encasement make sure they are in replacement.
  3. Where are you located? If you turn the jet faces counterclockwise they will unscrew from wall fitting. Take a look at o-ring gaskets and see what they look like. If white and you see cracks they have failed. To fix without cutting out plumbing and fittings requires sealing with Permatex ultra grey gasket maker according to Hot spring.
  4. The spa is miswired If the wires in photo are coded correctly with white being the 20amp neutral and green ground.
  5. I am in the USA so your spa is wired a little different could you show the inside of IQ box cover that has wiring and jumper configurations. ON USA Spas If the lim ok is not lit up the power light(red) on control panel will be flashing.
  6. If the red power light is blinking all functions of spa will be locked out except circ pump operation. Can you access the IQ Box and let us know what leds are lit up And photos help..
  7. On a 2008 control panel you have the red power light and green ready light . above is a blue fibre optic ambient light that is lit up from a led plugged into control panel . may need to check connection or wire behind bezel.
  8. Check to see if red low speed wire is on jet 2 low on IQ box, may have put it on jet1low.
  9. The temp control thermistor is plugged in wrong at main circuit board. Power down hot tub and move the 4pin connector that is right next to the "limit ok " led to the 4pin that is labeled"regtherm"
  10. You are having intermittent problems with circulation pump not working. Take the fuse assembly out of the equation to see if it solves the problem,if pump is getting constant 120v and not working it is time for new pump. The pumps have computer chip which helps to self prime impeller that probably went bad.
  11. Put black lead that is attached to inline fuse holder directly to board. those fuse holders get loose and cause problems. If it continues to not move water when getting proper voltage ,replace pump.
  12. Turn on both breakers in sub panel. If still getting E6 code the breaker is no good or wired wrong at terminal block in hot tub.
  13. I would put a non gfci 50amp in main panel and put the 20 and 30 gfcis out by the spa, like the manufacturer has it set up. It will also make the service tech or your life easier when you have a component failure. Also if you are in an area that has cold winters the main breaker tripping will result in total spa shut down which may lead to frozen hottub. Yes it more expensive now but could save you from major expense later.
  14. Bigspa If that serial number is correct the jet pumps need to be switched from 110volt to 220volt. The motor Plate will have the wiring diagram.
  15. Dave I just realized that we have two different hot tubs. With the limit ok lit and tstat good, the board should send power to heater and the heater led should light up. Is the summer timer on? If not then you may have an issue with main circuit board and or control panel.
