Pool heater Sta-rite error code 128 r5

SOURCE: pool heater

If the heater fails to ignite after three attempts, the heater will automatically go into Lock Out. This is a safety feature on the heater.

Things for you to look at to see what is causing the problem are the display panel and diagnostic lights. When you turn on the heater, is it reading the correct water temp? If not, the Thermister has gone bad and will need to be replaced. When you try to start the heater, is there an Error Code displayed? Which of the Service Lights are coming on when the heater will not light? If it is the Serivce System, that is usually low flow of water. You may have a dirty filter, skimmer or pump basket full of debris, or a valve not completely open.

If the Service System light is the one coming on, then you will need to take off the top two halves of the heater and turn over the Display Panel. There are diagnostic lights on the back side of the panel. There may be a red light next to any of the following:

AGS, AFS, SFS, HLS, PS or THERMISTOR

If there is a red light next to one of these, then that is what has malfunctioned. If you need an Owner's Manual for the heater, you can find one online at the following link:

The 126 is not an error code, but it maybe the temp of the water that the heater is reading. If the heater thinks the water is 126 degrees, it will not start at all.

If the heater is reading the wrong water temp, the problem is the Thermister, which is the sensor that is suppose to read the water temp. You will need to replace this sensor in order to correct the problem with the heater. It is really easy to do!

If you have a manual for the heater, if you go to the Replacement Parts Listing for the Electrical System, page 53 in the online version, the Thermistor is Item #9. It goes into the left side of the manifold in the to place, between the first two manifold bolts.

I am not sure if you have received an answer to the issue, or not, but just in case! An EO5 error code is an open stack flue sensor, or switch, There are two forms of the stack flue sensor, so you will need to know which one you have on the heater.

What this error code means is that the sensor "read" the flue temp to be over 500 degrees. Usually, it is just gone bad and reading the wrong temp.

IF you have tried to restart the heater and received the same outcome, the r5, or S, is a badk control board. Sorry about that one!

What you may want to try is resetting the heater. You will need to put the SunTouch in the maintenance mode. Then turn off the heater, turn off the Circuit Breaker for the heater, wait about 15 to 20 minutes, then reverse the order. Circuit breaker, then heater, then try and start the heater without the SunTouch first. If it works, then try with the SunTouch.

Its the top. There is a membrane that controls the circuit board....the button pad is bad

Testimonial: "Thanks, I agree. After checking power supply all the way through to control board, placing a jumper from pins 9/8 and 9/7 on J6 I get lights on LED's"
