Re: My Heater shuts down and I don't have a manuual to...
I NEED TO KNOW WHAT THE EE2 CODE MEANS.ON YOUR FURNACE THERE IS A LIST OF ERROR CODES,PROBABLY ON THE BACK OF THE DOOR ON THE HEATER.WE NEED TO START FROM THERE TO GET AN UNDERSTANDING OF WHAT THE UNIT IS TRYING TO TELL US. JEFF

Check your stack flu sensor. Sensor can not be jumped. As soon as the heater fires hold down the pool or spa button until the stack temp appears. At 500 degrees the heater will shut off giving a code. The heater should not restart. I would also check for wire damage based on the description of your issue and the board restarting on it own. You may also have damage to the "user interface board" , hard to say with out on site trouble shooting.
A host of problems develop on these heaters by draining fuel to supply the heater from the tank bottom. Use the bottom tank port to pull off moisture occasionally and get equipped with a top mount duplex tank bushing. Plug one of the 2 ports on the bushing, feed 3/8" soft copper tube into the brass adapter until copper touches bottom of tank;(you'll need to hand straighten it as it goes in), scribe a sharpie mark on the copper for a reference point and pull the tube back out 2-3 inches. Now your fuel supply is above any reasonable moisture accumulation in the tank. Bend tube gently and route to your heater. Don't think your heater impulse pump will **** from the tank, you have to prime it by sucking and it will work by siphon to feed your heater forever if the tank doesn't run out of fuel. Don't forget a good inline filter isolated with valve each side. Ideally this should be placed lower than the lowest expect fuel level in the tank.Best of good luck to you. email@example.com
EE 2 can be caused by a couple of things but is usually a fuel issue or a flame rod problem. The circulation fan will not come on until the burner has warmed up. The combustion blower should start almost as soon as you turn the heater on. Turn the heater on and listen for the combustion blower. If it doesn\'t start, do you get an error code? If the blower started wait for the fuel pump to come on. It will start when the burner lights come on. If the fuel pump makes a loud ticking or thumping sound, it isn\'t getting any fuel. Check the fuel filter and the strainer in the fuel sump. Make sure the valve is turned off at the barrel before removing the fuel strainer. If the fuel pump is working normally, does the heater light up. If it doesn\'t, check the igniter. You can check that first if you want and have a clamp on ammeter. Place it around one of the igniter leads and you should read 2 to 4 amps when you turn the heater on. If the heater does light but then cuts off after about a minute, clean the flame rod. Unplug the heater before removing the flame rod because it may kill the circuit board if the heater is plugged in and the flame rod touches ground. Let me know what you find.
Probably a fuel flow problem. Does the pump start making a loud thumping sound before the heater cuts off. Check the fuel filter and the strainer in the fue sump. Turn off the fuel at the barrel before removing the fuel strainer. Also check the flame sensor. Unplug the heater before attempting to remove the flame rod because it may burn out the circuit board if it touches metal with the heater plugged in. Use some steelwool or fine sandpaper to clean it if it is dirty. Another possibility with the EE-6 is that it is overheating, however, since you are getting EE-2 also I would suspect that fuel is the problem. Another thing to check would be the fuel nozzle. It can sometimes get clogged with carbon deposits. Let me know what you find if this doesn't fix it.
EE 2 means its not getting fuel, your flame sensor could be dirty, or there could be a problem with the circuit board. The heater goes thru a 3 min warm-up/purge before the pump comes on. If the pump is making a loud ticking sound then it isn't getting fuel. You should then check your filter and the strainer in the fuel sump. If the pump isn't making a noise you could check the flame rod and clean it with some steel wool. You should check to make sure the igniter is working also. After you turn your heater on the cover on the igniter will start to get warm and will get very hot before the purge is done so use caution. Hope this helps.
Clear all the paper out of your fuser (don't use a sharp object) and anything in the paper path before and after it. Clear the code with pound-star-C-star-14-start-yes-CA. If it still comes back you have a broken sensor or sensor flag in your fuser.
