Turn off power, if still running - new water solenoid required.
If it stops running with the power off, then check and clean the level probe. If that dont do it. new control.

Lazer 30 error 22 on panel

The stove quit three times with an ee2 message. The stove is trying to save you from flooding. You may have a fuel problem that is causing the ee2 problem. After three time the stove locks out and won't let you try again. Find out whats up with the fuel. Unplug the heater for 20 minutes and you will be able to try again. Also make sure the igniter is getting hot. Two red wires going into the burner should get hot.

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.

Ignition keeps burning out. Also has crusty carbon deposit building up on bottom. Smelly sooty exhaust prior to failure of igniter. Fuel is clean and filter is too. I have a Lazer 73

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.

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.

Rheem Classic 90 Plus nat. gas furnace status LED flashes twice (pressure switch issue). Service provider replaced switches on second visit. Problem persists. Plug has been (temporarily) removed from...

Check the air filter, condensate drain lines for blockage and vent piping for a build-up of water. If nothing, you will be needing to replace the circuit board (hopefully under warranty).

No hot water - Rinnai tankless hot water heater

sounds like the water line is frozen before it gets to heater. You can take a blow dryer and try to thaw the line.You should be able to hook up a hose on the hot side of water heater. turn valve off so it wont flow into house.You can turn on hot water valve on in kitchen but you will have to thaw cold and hot line. Make sure you know where water shut off is to the house just in case a line breaks.

No hot water

An error code of 11 equals no ignition. Check gas supply, sparker, flame rod, burner and ground.
