Question about Rinnai Toyostove Direct Vent Heater: Toyostove Laser 73 Shipping
Ok so I bought a L 73 model two years ago and today I had fuel delivered in prep for the winter. When I turned the Toyo on it waited about 5 minutes before giving me an EE 08 error message. The manual showed blower motor trouble and I was bummed so I called a friend. He gave me the following information he learned from a Toyo dealer as a "temp" fix until a more thorough cleaning can take place.
Apparently stuff (crusties, ash and burnt debris) have a tendency to build up around the blower motor fan which causes it to get stuck. This is not the large visible fan on the back, but the smaller internal one. There is a rubberized hose leading to the larger fan and a smaller flexible stainless exhaust next to it, which is the one I was told to remove.
Once you remove the flexible exhaust get a flashlight and look into the back and you'll see the fan (or only about the 1/3 of it which is visible). Take a pencil eraser and gently remove the build up between the exhaust slats. I also used my craftsman shop vac which fit nicely right over the hole to remove the debris. Once you have all the soot, crusties and stuff removed the fan should be spinning at warp speed when you remove the shop vac.
This took my literally about 10 minutes to disconnect, clean and reconnect. About 8-10 minutes later the unit was working great! Hope this helps anyone having similar problems.

no ignition: out of fuel check fuel gauge or tank, refuel
fuel tank valve closed open valve turning clockwise
air pocket in fuel line push reset button on the fuel sump, located right inside .
clogged flue pipe clean flue pipe
clogged fuel strainer clean fuel strainer

it sounds like it may be a clogged strainer located in fuel sump or a bad circuit board hope this helps

Try this lick to REE. They are Toyotomi supplier on the west coast.

I see that you say your fuel is clean but igniter failure is commonly caused by tiny drops of water hitting the hot igniter. A sign of this is small pin holes in the igniter and a pinkish color. You could check the voltage on the ckt board where the igniter connects. I think it is 120vac but I don't have the manual in front of me. Excessive voltage could burn it out alsl. You need to clean the carbon deposits but be careful not to destroy the burner mat. You would have to take the combustion chamber apart to do this. Check you igniter gasket, this could be the cause of the smell. If you can take the top off of the fuel sump, look in there and make sure there is no water contamination. Let me know what you find.

EE10 is not good. This means you had a flame in the pot when there should not have been one. The red button is to be used very carefully. One time for one second. I think you have pushed the button too much and got a fair amount of fuel into the burner. Without pushing the red button try the stove again. If you burn out the fuel in the burner the stove will operate normally. If the code continues I would look at the hook up for the air and exhaust to be sure they are correct. If they are backward it can cause an EE10.
Keep us posted,

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.
