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!

Have 40 gallon electric hot water tank 10 gauge wire 20 amp double pole breaker federal pacific fuse box red black ground wire shows power on 2 hrs now not even Luke warm water what could be wrong


I'm an electrician and can help. Federal Pacific equipment is tough stuff. The company went out of business decades ago - due to faulty equipment they made. Aside from that..

There may be no power out of the breaker, bad connections between the breaker and water heater, bad thermostat, bad hi temp sensor, bad heating element and more. I wrote the article linked below - that will help you find and fix any of these problems and more - assuming you have the equipment and ability to work on electric water heaters. If not - call a licensed electrician.

Thermostat for mdl te420t


Take the.plate off of the bottom cover of the water heater after turning off the breaker or removing the fuse from your main electrical panel. After you have done this and the plate is off remove the insulation from over the plastic cap that covers the thermostat/heating element. This thermostat. Controls both heating elements if your heater has two elements. After you take the plastic cover off the thermostat, turn the dial counterclockwise to the desired temp. I find that a 125 degrees is optimum for my household, but I live alone. If you have a family you may want to go a bit higher, 130-140. Also if it is electric get a water softener. It will save you time, money, sweat, and a lot cussing while you're changing water heater elements. Learned from experience on that one plus it deeps your fixtures lime free. Best investment I ever made.

Rheem 50 gallon Electric Water Heater 81V52D C repair ideas needed


It could be element shorted to ground through steel tank, so don't touch tank when breaker is ON.
Or you have undersized 12 gauge wire and 20 amp breaker and the heat has loosened breaker on the busbar. Breaker trips when heat exceeds breaker limit. Jiggle breaker and listen for crackling sound.

To restore hot water now:
Turn off circuit breaker, and open top cover then Push in reset button on top of heater to restore functionality. Put back insulation and factory cover.
To fix water heater: test and replace bad element.

Rheem rte13 standby (green) light not on


You might have crossover problem caused by bad faucet cartridge.
http://waterheatertimer.org/Crossover.html

The green standby light should come on when 240Volt power is applied. Page 6 manual.
Both red lights should come on when tankless is activated. Page 6 manual

RTE 13 requires 60 amp breaker and 6 gauge wire
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html
http://waterheatertimer.org/pdf/Rheem-TanklessElectricUC_AP15447.pdf

Factory temperature setting is usually default 120 degrees.
Adjust temps page 11 manual
Thermostat calibration is always approximate.
120 degrees is not hot enough to burn the skin.
Exceptionally cold incoming water temperature can cause tankless not to heat enough hot water: install tempering tank to preheat water to room temperature.
Tankless cannot be exposed to more than 11 grains hardness in water. Delime tankless yearly, clean water filter monthly, do not install low-flow restrictions or conserve water since the flow rate must remain high for tankless to activate.
Rheem does not post service manuals for their tankless water heaters.

Powerstar 115 tankless tripping reset ontop of #2 heat chamber #1 does not get overly warm mainly because of incoming water temp. but #2 seems to be heating after water flow stops to hot to touch and...


I don't have specific suggestion for tankless tripping breaker or if that is a circuit breaker problem or a tankless problem.

1) Move wires to another same-size breaker and see if problem persists.

2) Compare amp draw on tankless label with wire size and breaker size amp rating.
For example 30 amp breaker using 10ga wire is rated for 80% of listed amps or 24 amps.

3) If you are drawing full 30 amps, then 30 amp breaker is getting hot. Breaker trips with heat. Older breakers can trip more easily.

4) Before calling service technician, open following link for Bosch troubleshooting steps.
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

5) Be sure to read manual for yearly maintenance requirements.

6) Add a tempering tank for incoming cold water problem.

7) All gas tankless brands can be repaired by homeowner for $330.

sorry to say but when you drain an electric water heater and dont turn off the power to it . the elements fry. so make sure breaker is off drain tank and replace the elements refill and then turn breaker back on and all should be fine.hope this helps have a good day!

VERY LITTLE WATER HEAT


What is the inlet temp of the water? If it is cold, your output will suffer. What is the flow into the unit? If it's too fast it doesn't have the proper time to heat the water to full temp. Is this gas or electric? Electric units have more issues than gas. If its electric, one of the elements could be bad. Check your breakers and make sure one of them hasn't tripped (electric). If it is gas, check that you have the correct temp set.

Electric Water Heater Problem


When an electric water heater fails to heat water, either the power to the water heater has been interrupted or there is a problem with the controls or the heating elements. 1) Be sure electricity is being delivered to the appliance. Check the main switch on the water heater and the circuit breaker (or fuse) that serves the water heater. 2) Check the high-temperature cutoff in the water heater. Open the panel, and push the reset button. 3) If these steps don’t solve the problem, call an appliance repairperson.
