There is a short somewhere ... You will have to get the fault fixed so the safety will stay engaged.

Probably not what you wanted to hear.

Remove the wires at both ends of the thermal cut-off that is located in the little plastic sleeve below the pressure relief valve area and it's connected to spade connector on thermostat disc. Once removed, connect the female spade from wire to male spade on thermostat disc, and try to light now. If all's o.k. replace thermal cut-off as it is a safety feature to protect in case of flame up.
If not, get back to me.

This is common problem with tank-less electric water heaters. There a a couple of things you can do. Turn the temperature down on the thermostat, this will lower the power requirement. The other thing you can do is replace the safety thermal cut-off switch. If you have two or three replace then all at the same time. Thermal safety switches are manufactured by the hundreds of thousands and go bad quit often. Contact the manufacture for free replacement parts.

E.C.O. is Emergency Cut Out, or some say emergency cut off, whatever. It is a safety item that will cut out, in case the thermostat malfunctions.Basically same as a high limit switch, cuts off power if temperature gets too high.

The ECO is designed to shut off the water heater in case of the water heater overheating. This is to prevent the water heater from exploding. I assume that you have a newer style residental water heater or a commerical boiler. The ECO is a fuseable link that is built into the control and located at the thermostat probe. If the water heater overheats then this link will melt cutting the circuit on the millivolt system(residential) or 24volt system(commercial boiler). If you look under the water heater control(where the temp adjustment is) there are usuall two wires that go from the control to the water heater. These are the ECO wires. Verify the wires have not been cut or damaged. If these wires are cut or damaged then the ECO circuit will be incomplete and you will get the ECO lockout failure. Also make sure that the flame lock-out switch is not tripped. It will be located at the burner compartment cover and have two wires going to it. Most have a little button in the center. These are to sense high heat and one might have tripped closing the circuit. You can push this little button to re-set the switch. If you feel a little "click" then the switch was probably tripped. If it does not have any button then it might be "self resetting". To test that switch use a continuity tester and the circuit should be closed. If these switches are working then the fusable link for the ECO is probably bad from the water heater temp getting too high or was defective and failed. This will require you to remove the water heater control valve and replace the fusable link. If you do not have experience with this I suggest you call a licensed plumber to make the repairs. If this repair is improperly done it could void the warranty on the water heater and/or cause property/personal damage or injury. There is a possiblilty that your water heater thermostat had failed causing the ECO to trip. If that is the case then the ECO safety did it's job.

the diagram on this page shows the safety thermal cut-off on top of the heating vessel on the right, inside the unit, remember to electrically isolate before opening.http://www.tanklesswaterheaters.com/tempra12.html

Hi, first check and try and reset the breaker feeding the water heater. That should be a two pole breaker. The next thing to check is the red safety button on the top thermostat control. It is under the top access panel of the heater, along with a good amount of insulation. Push the red button to reset the safety switch. If these do not remedy your situation, then you will need someone on site to check the water heater in more detail.

Maybe you need to reset the switch.Let ask you this. What type of gas do you have coming to this heater?
