Heater wont fire display not reading anything no error codes on IID or lights on back of board


How old is the heater? Is the control fuse good? The issue you are describing is exactly what should happen if you power up the heater and DO NOT select POOL or SPA. If the membrane pad on top of the heater is not working or the user-interface board is bad then the heater will not be able to turn the heater on.

When turning on power display reads 128 then error code r 13, after this it say's spa on but the temp reads 126 and the water temp is only about 68 so the heater never comes on.


This is not an error code. 128 r13 is the normal programming or software version for your model. you need to press the spa on button again, make sure the temp set point is higher then the actual water temperature

I turn on the heater and get error code R=9 and then shuts off....what do I do?


Hi,
R9 is not an error code, but a software revision code.

Here is what you should do.
Take off the front panel underneath the circuit board.
Turn the heater on, if it doesn't Fire and gives no error code you need to look at the back of he circuit board and see what red lights are on. If you find one on there will be letters next to it to point you in the right direction of the issue. Example h1 or h2 would mean high limit 1 or 2.
If you don't have space to look by taking off the front panel only then you would have to take all panels off and get the top loose so you can lift it carefully to access the back of the circuit board.
Once you've done this let me know what you find and I may be able to further assist

I have two error codes: 180/R9 anlong with 128/R8 HELP!


Error pertains to stack flue sensor setting.
There are two modes for low level programming and default is a (0) Zero but for outdoor spas this must be reset to a one ( 1 )
Just hold the off button down for 30 seconds let up, press down again, use arrow buttons on key pad to set from 0 to 1...press off again....play with it and see for yourself...I don't now why Sta-rite buries this information and makes us guess.

Again, on mine, this all pertains to the Stack Flue Sensor setting.... you can look at your heater and see what they look like...outside toward bottom the SF must be a 1 and not Zero or you get the quick flash 128-R8 notice...also, the Stack flue senor is finicky and connections must be good...use steal wool to re-seat but be careful as connector break off easily thus requiring a new stack flue sensor...
I accidentally discovered this when I turned the board upside down and spotted the LED red light on indicating a fault with the SFS**

I wish some one would tell us how to by-pass the stack flue sensor to make the heater work.
Good luck...hopefully the power button is close by and your board is working....

Fault code R9 comes on


R9 is a boot up sequence number. If possible, remove the top disk to view the circuit board under the control panel and start the heater again, look for any fault LEDs to illuminate.
