Atwood 6gal self ignite wont stay lit


Are you sure of model number, as it doesn't indicate electronic ignition. That said, if you do have electronic ignition, there is a small thermal cut-out in power line (brown wire) to thermostat terminal. It is inside the clear plastic sleeve and is connected between power wire and thermostat. Pull it apart and remove that thermal cut out temporarily and just connect wire direct to thermostat terminal where other end came off. Now try it, if it ignites and runs good, replace that thermal cut out. If no better, get back to me. That thermal cut out is a safety device in case of flame up, so be sure to replace it once diagnosis confirms it is defective.

High temperature thermal cut-out has tripped


Type, model, brand, age of water heater, and general installation of water heater are unknown.

1) Electric tank-type water heater: replace thermostats and test elements.

2) Gas tank-type: replace gas control valve, clean air intake screen/ location varies by brand:

3) Tankless: call service technician, or replace tankless with tank-type and save money long-term.

4) Add comment and describe water heater using label located on side of unit, and include what you are doing to 'reset' the thermal cut-out.

The safety thermal cut off switch keep cutting off and am not getting any hot water in the shower


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.

My Tempra, 29 Plus quit heating. I checked the breakers and they are ON. Where is the thermal cut-out located ? How is it reset? What temperatue should I set on the dial?


Take off front cover, on the top of the two cylinders in there (the heating system) there will be a small red button. That is the Safety Thermal Cut out, depress that red button. It is similar to a circuit breaker. If the red LED comes on when you turn on hot water at a sink then that was the problem. I have on that trips periodically. Its annoying but not enough to replace the part yet. Good luck.

The internal circut breaker snaps off soon after water starts to pass though. Why would that happen?


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.

Where do I find the reset button on the Stiebel Eltron Tempra 15?


On the Tempra 29 there is a "safety thermal cut-out" on the top of each of the heating elements within the box. I have had to open it up before to push the breaker. They are a small red plastic push button on the top. Carefully press the braker button without touching the electrical wiring inside. I hope that works for you.

Bosch PowerStar125 won't heat and I can't get one element to work


It sounds like you have a copper canister unit. Ohm out the elements in that one canister. the directions are on the websight for bosch, or I can walk you through it. But you will need a digital multimeter to do this. If you have a blown element in that one canister, then the tco will not reset.
