New haywood pool heater to hook to sta rite mx1000 heater control box

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:

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.

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"

make sure that you have adequate water flow going through the heater and that your water chemistry is balanced.
