Question about Rinnai Toyostove Direct Vent Heater: Laser 56 Toyostove Direct Vent Heater

1 Answer

I have a lazer 56, EE2 is showing up. I cleaned the sensor and the heating rod. It doesn't seem to be pumping any fuel. I also cleaned the filter in the fuel sump? Could it possibly be the fuel pump, it doesn't seem to be pumping fuel?

This is usually a fuel flow problem. If you have a filter at your oil barrel you should check it. Does the fuel pump make a loud thumping noise? If it does, the fuel isn't making it to the fuel pump. It can also be caused by a bad igniter. Use an ohmmeter to check the igniter. Connect it to the ends of the igniter leads. It should read between 15 - 20 ohms. You can also feel the igniter cover while it is going through the start up cycle. It should get warm and may be hot. You can check the fuel pump by removing the fuel line from the burner and directing it into a bowl to see if it is pumping. The pump will not start pumping until the burner lights come on. Also try pressing the fuel reset button on the right side of the heater. It is on the fuel sump. Let me know what you find and I can give you more advice if needed. Your vote and any testimonial are also appreciated.

I keep finding my Lazer 56 off, with the code EE6. What does that mean?


This could be several things. It could be a problem with fuel flow, the high temperature limit is activated, or a problem with the flame rod. Start by checking your filter at the barrel and the strainer in the fuel sump. If you hear a ticking or thumping noise before it cuts off, you are not getting fuel to the fuel pump. Next you can clean your flame rod with some steelwool or fine sandpaper. Lastly, make sure the circulating fan is running and nothing is blocking the air to fan. You can also clean the fan blades if they are dirty.

My toyo lazer 30 won't start, and the EE2 problem comes up.


With an EE2 message you have a problem with the stove igniting during start up. If you continue to try you will end up with an EE22 and the stove will be locked out. If so, un plug for 20 minutes. While you are waiting check out you fuel system. Low fuel, no fuel, dirty filter on tank and stove. Be sure to bled the air off the top of the filter when you change it.

Keep us posted.

I have an error EE 2 on my lazer 56 toyostove Does anyone know what that means?


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.

Toyo Laser 56 EE2 message--no flame? valves open and clean filter


You might of got type 2 fuel oil. If it is a smaller tank sometimes the fueler doesn't clear the line before filling and you'll slug down some type2 which will snuff the flame.
Check to see if the filler kinked a line outside while filling.
Just an Idea...

Heater want work right


EE2 Means only one thing. The flame rod is not detecting a flame.
The cause could be anything that prevents a flame.
1) no fuel
a) out of fuel - check tank
b) clogged line - clean
c) clogged filter (either on tank or screen in stove) -clean
d) igniter not working- replace
e) dirty flame rod (clean, then determine why it's dirty or it will happen again)
those are the quick fixes other than that contact the dealer you bought it from.

Toyostove Laser 56 EE 2 error


Tim,

I have been working on Toyo's for 14 years now. During this time I have never seen a flame rod that was bad except ones that people have broken themselves. The rod is just a piece of heavy wire that is insulated against the pot. It is almost impossible to mess it up. Now, that being said, you can have a problem with the flame rod being dirty or sooted. Since your stove is so new I would look at the fuel system. If it is clean I would go after the burner mat. There have been mats lately on new stoves that have caused them to soot up. When this happens the flame rod gets covered with soot and gives the EE2 message. A new stove that has a burner mat problem would be covered by the warranty. Bad fuel that causes a problem will not be covered. The other thing that is not covered is a stove that has had an iced up the exhaust pipe. A good dealer should be able to help you get the stove going and explain the warranty.

EE2 code for toyo laser 56


Hi sammysamual,

My business is Laser Heating Service in the North Pole/Fairbanks areas of Alaska. An EE2 error code is usually fuel related. What does your Toyo do before the EE2 code shows up? If you let me know the sequence of events, I can trouble shoot the problem for you. toyotech

EE2 code for toyo 56


Hi sammysamual,

My business is Laser Heating Service in the North Pole/Fairbanks areas of Alaska. An EE2 error code is usually fuel related. What does your Toyo do before the EE2 code shows up? The firing process is the burner button blinks green for 7-9 minutes, then it clicks up to the medium, yellow light which starts flashing. That is when the fuel pump starts pumping. If you hear a fairly audible tic tic, or thump thump coming from the fuel pump then that is your indication that the fuel pump is starving for fuel. You either have a fuel line restriction, too little fuel, a clogged filter, a clogged sump screen, or rarely, a failing fuel pump. Usually, it is a fuel line restriction.

If you hear no tic tic or thump thump and it just goes off on EE2 then the problem is in the burn chamber. You may have a carbon chain in the chamber causing the flame sensor to temporarily short out. You can clean the flame sensor, fuel nozzle, and igniter to resolve this problem until you can get your Toyo tuned up.

EE2 code for toyo 3


What Does EE2 Mean? Laser 30, 56, and 73 model Laser heaters cease operation and display
the EE2 code on the control panel (instead of the clock or temperature settings) when the primary
flame rod on the heater fails to sense a flame during the first 5 minutes of the Ignition and Pre-
Heat cycle. On the Laser 55 and 72 the heater will stop and the red Reset lamp will light rather
than the EE2 code. (Note: There may be other reasons for the reset lamp to come on but much of
this information will apply.)
What Can Cause An EE2 Error? The primary flame rod is the only sensor in the heater that
can cause the EE2 error. Thus, if it occurs, either there is (1) no flame to detect, or (2) the
sensor failed to detect the flame. The flame rod is located on the lower 1/3 of the burner. It is a
heavy wire with a ceramic insulator. A single white insulated wire connects this device to the
main circuit board.
