We have situations like that where even with an electrical meter it may appear that both sides of the panel have voltage when actually one of the main breakers or fuse has blown. If that is the case power flows through some 220 volt devices to feed the second side of the panel but no 220 volt appliances work. If that is the case then the voltage will not be 120 volts on the second side but some lighting has a brown out or too low of a voltage. If none of this is happening then you have blown your element. To prove that... verify with a multimeter that you have 220 volts on the element.

SOURCE: Water heater with electonic igniter will not work in power outage

What type of heater is this? I need to know the model name and make and then we can go threw the process of how to do it. Most gas heaters do not have power to them and I only know of a few tankless heaters that do.

SOURCE: ON-DEMAND WATER HEATER NOT WORKING

I am assuming that this is an electric unit? The heating elements could be bad. I would contact the manufacturer for a service manual for your unit. There you will find instructions on how you might be able to reset the unit if possible. One thing you can try is to shut all power down to the unit and then restart. Also check for any "reset" switches on it as well.

SOURCE: Power outage caused c8 / 76 error - No Hot Water

How old is your unit...if less than 5 years old tell Polam/Rheem customer support you are recieving a code 76 error - this is a loss of communication between the remote and the burner control assembly. Part will be covered under MF defect warranty. However, the part is covered....the labor to install is not.
If you are slightly technical you can install the part yourself...customer support will walk you through the process and they give you a step-by-step procedure to follow.

SOURCE: Too much water draining from Vulcan Electric H/W relief valve.

Dear Julie. Do you have an expansion tank installed? If so it is probably waterlogged. If you come home shower etc. use lots hot water then go to bed or leave the cold water in your tank heats and expands as it heats. In the old days a toilet ballcock valve would relieve this pressure but modern toilets with diaphragm valves wont so the pt valve relieves pressure. Installing an expansion tank on the cold water line near the heater will absorb the extra water & stop the pt valve from activating.

SOURCE: i switched off the power to my electric rheem 142

Turn power off to water heater at breaker panel, remove cover where electrical cord is, and check behind it for thermostat, with red button in center, push it in to reset. It may have tripped for some reason when power turned back on to it. Do you have a multimeter, to test for power at heating element?

Water inside tank-type water heater can remain hot for some time.
That's one advantage of well-insulated tank-type water heaters.

Power outage can be related to failure of gas control.
Unplug stuff when power goes out. And then plug back in after power is restored.
Water heaters with electronics are not protected from surge.
Electronics can blow out during and after power outage. For example nearby lightning strike will cause current to run along household wires. With ordinary power outage, once power is restored, the surge can affect all kinds of electronic circuitry such as timers, water heaters, water softener, treadmill etc.

Sounds like you have intellivent gas control valve:

I want to add an under-counter auxiliary water heater to my 15A dishwasher circuit. I need to install some sort of relay to cut out the water heater when the dishwasher is being run, to avoid overloading...


If I understand correctly you have 15 amp breaker with 14gauge wire.
Total watt capacity of 15 amp breaker is recommended at 80% rated load = 12 amps

You want to connect two appliances to same 15 amp line.
1) You have 6 amp Dishwasher that draws 720 Watts
2) You have under the counter water heater with 1500 Watt element that draws 12.5 amps.
3) Combined load is 18.5 Amps and 2220 Watts, approximately
So you do not want dishwasher and water heater turned on at same time.
Makes good sense.

Solutions:
> Easiest thing would be to put water heater on ordinary wall switch located inside sink cabinet.
Back when garbage disposals first came out, garbage disposal switch was inside sink cabinet. You opened cabine door and flipped the switch.
> Next solution would be to put water heater on a timer located under the sink. There are different timers. In-wall timers and box-type

In-wall timer would need relay/contactor
A battery operated timer like the ST01C would not need to be reset after power outage
http://waterheatertimer.org/Programmable.html
Here are instruction pages for selecting and installing the relay/contactor.
http://waterheatertimer.org/H230A.html
http://waterheatertimer.org/Install.html
Add a comment any time.

Box-type timer like T101 120Volt timer. This timer needs no relay/contactor.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101
Timer needs to be reset after power outage, but operates on ordinary 120V power, and is simple to install.

> There is no easy way to wire the dishwasher and water heater together so one is certain not to operate when other is turned on. There are likely electronic control panels for that project. But since you know the hours when dishwasher is likely to be ON, then set water heater timer to turn OFF during those hours. Water inside tank will stay hot for a couple hours, so there is no loss.

It sounds like you are a solid electrician.
If needed, add comment any time for more assistance.

Lower element will always test 120V to ground since thermostats turn off one hot wire.

Listed below are suspects in order of ease.

1) Check that hot water is not running out of TP valve and down into a drain.
This will cause water heater to run all the time but not be able to keep up.

2) Test elements before replacing anything:
http://waterheatertimer.org/How-to-test-water-heater-element.html

3) Test electricity to water heater:
http://waterheatertimer.org/Test-electricity-to-water-heater.html

4) Replace both thermostats.

New Rheem electric 50 gallon not heating


Check the elements, if you have access to a meter to check them. If they are getting power to elements and you have no hot water.
The elements are not working correctly. I had some elements check out ok till the thermostat's turned on and the elements didn't heat.
Sounds like the elements are bad.

Hello. If you turn off the power and drain the tank then examine each of the heating elements you will find that the upper element is deteriorated. The fix is to replace the heating element. Actually though my practice is when one is bad the other isn't far behind so for a few dollars I change both when I have the tank drained. Joe
