My heater stoped heating water. the light is out that shows temp.my husband is in Military and i am alone. I checked circut breaker but I don't know if or where there is a circuit breaker at the box or a reset button??/ can you help me or send a diagram> Linda

I had the same problem with the Stiebel Eltron Tempura 24. Right side unit worked (with blinking LED), but the display and left side (including LED) did not work.

This is CRITICAL. Do not take the cover off unless you have turned off circuit breakers at the circuit breaker panel AND tested that there is no power. There is a lot of voltage/ampreage here and it could be life threatening if you get shocked. Call an electrician (or a plumber) if you don't know what you are doing.

My problem was solved by resetting the safety thermal cutout switch on top of the non working unit (red single press thermistor). See this manual http://www.stiebel-eltron-usa.com/pdf/install_tempra.pdf page 8.

Hello Linda, Open your circuit breaker box. On some, manufactures breakers you will see red on the breaker, Or see if someone labeled the heater in the panel that you opened. "Hot water heater/heater etc." or with a flashlight check carefully each breaker. Some will show half way off or half way on, like in the middle. Circuit breaker are ether ON OR OFF. To reset turn it to off and back to on!
