My business is Laser Heating Service in the North Pole/Fairbanks area of Alaska. EE12 is the error code for overheating. Most likely you have a Laser 30 giving you this error code. The most common reason for the EE12 error code is that the Toyo is not getting enough air circulation across the heat exchanger and causing it to overheat. Look at the back of your Toyo where the black frame around the circulating fan and flue pipe is. You will see a screen that slides in a slot at the back of the Toyo. Slide the screen out and clean it. If you have a smoker or the Toyo is in a kitchen area where it collects nicotine or grease then you may need to clean it with hot water, detergent, or 409 Cleaner to get the sticky residue off that the dust fuzz collects on and clog your screen. EE12 can be caused by a couple other issues, but they are more rare. Try this first and let me know if it works! toyotechnician

Call manufacturer or Installer - Direct Vent Furnaces are not a DIY service. Carbon Monoxide is deadly and can easily be emitted if there is something wrong with the heater. Get professional help before anything further is done, as it needs a full inspection for your safety.
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 usually has to do with the fuel. Does the heater make a loud ticking or thumping sound? That's the sound the fuel pump makes when its not getting any fuel. Check your filter, check the strainer in the fuel sump. Depending on how cold it is any water in the fuel line could be frozen blocking the fuel flow. You might also check the flame rod for soot. It can be cleaned with some steel wool.(email@example.com)
Could be water in your barrel. Did you replace the filter? It can freeze and block the fuel flow. Check the strainer in the fuel sump. Is your code EE 6 or EE 2. Depending on the code you may need to clean the flame rod.
If you can't get rid of the EE8 message and you think the motor is really turning it may be turning too slow. This will be caused by corrosion that has dripped down into the blower and gotten on the Rev sensor. The solution is to change the motor. If you are not handy with tools you may have to just change the whole blower. The motor is around $150, the whole blower is $350. The corrosion may have happened over the summer and fall.Heating and cooling causes condensation and the water drips down into the blower.
How long has it been since you've cleaned your stove? If it's been a while the flame sensor (the part with the metal rod) may be building up a chain of carbon blocking the igniter from igniting the flame. A temp fix is to jiggle the sssensor but what is needed is a cleaning. Also you may need a new burner ring. That solved my problem last winter.
EE-22 means that the unit has tried three times to ignite. after this it goes into a "lockout" condition. remove the power and the computer will reset itself. it will then try to re-ignite. check for a fuel blockage, dirty filter etc. if there's water in your kerosene it will not fire! kerosene floats on top of water. bleed your system until you get kero and no water. use a gas additive to remove water. dry-gas will work. just empty the bottle's contents into your tank. on your computer type in toyostove error codes. this will take you to toyo's site and explains the error codes.
code 12 is low gas pressure, or that the flame sensors are not picking up a flame, try removing the flame rods, in a rinnai infinity when you pull the cover off they are right in the middle, you can use a file to clean any carbon etc off,
