SOURCE: after about an hour the breaker trips

I would say then the heating element has a resistive short to ground. The 1.98m Ohm reading is high, but not high enough -- should be infinite. I would say replace heating element... And, when you install new one, make sure there is no water leaking thru heating element cavity and ensure area around cavity is clean & "in order".

How old is water heater?

SOURCE: I had a bad lower element, replaced it, refilled

Check power going into thermostat and coming out. Power comes through top thermostat to rest of electrical component's. Thermostat may be tripped out if so press red reset button. If it don't reset the thermostat may be bad.

SOURCE: upper heating element never turns on just replaced

If you have 220 volts at the poles on the upper heating element and it doesn't heat up, it has to be the element or a loose connection where the power hooks up to it. If after replacing the element and the power was applied to the element before the tank filled back up with water, the element probably burned out again. The tank must be full before turning power on to the tank.

Replacement element part # for 83VR52-2


Look at watt rating printed on end of each element.
Elements are generic and available at hardware store.
You do not need special element. Just match the wattage, or choose less wattage, do not choose higher wattage.

Might pick up both thermostats too.

Replaced both lower and top elements and upper thermostat still no hot water. proper elec. going to unit.what could it be?


You need to take 1/2 hour to learn basics and then test water heater parts before replacing anything.
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html
Follow the troubleshooting steps, and it will tell you exactly where the problem is.
Otherwise we can guess at 20 different things.

Water heater is 240V because you have more than 1 element.
Did you test for 240V across top two screws of upper element?
Breaker can be tripped off on one leg and 120V arrives at water heater so heater looks like it has electricity, but circuit is not complete.

The problem can be loose wire, bad 240V circuit breaker, sediment reaching lower element, bad thermostat, bad upper element, tripped ECO reset button.

Did you replace factory insulation and cover over thermostats after replacing elements?
Did you vacuum out sediment when replacing lower element?

How long ago did you replace elements? If you turned power ON before tank was completely filled with water, then you burned out the element. If upper element is burned out, the tank has no hot water, even if lower element is good.
Test the upper element:
http://waterheatertimer.org/How-to-test-water-heater-element.html
See how a water heater works:
http://waterheatertimer.org/How-it-works.html

And finally, why so many folks write to fixya saying they replaced both elements and upper thermostat, but they never replace lower thermostat for another $6? I have been puzzled about that since lower thermostat turns on and off each time tank temperature drops and is responsible for keeping water warm during standby hours. Lower thermostat cycles more times than upper thermostat.

Add a comment if you need specific assistance with any of the testing steps.

We just recently replaced both heating elements in our water heater. Now the water is just barely getting warm and not hot. What's wrong??


Electric water heater if fully repairable by homeowner:

A] First of all, we know your upper element is working because you have some hot water:
http://waterheatertimer.org/How-it-works.html
That says tank is not overheating.
It says tank is getting 240Volts.
It we know water heater is 240Volts because you have 2 elements.
And it says reset button is not tripped.

B] That leaves 4 suspects:
Suspect 1) Bad Upper thermostat or Bad Lower thermostat: solution replace both thermostats for about 25$. Steps shown in link below.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Suspect 2) Burned out Lower element: solution take out element, clean sediment out of tank, put in new element. Steps shown in link below
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
Suspect 3) Loose wire or connection: solution open covers and remove insulation and look for signs of burning and high heat. Tighten all screws very tight. Replace burned part. Put insulation and covers back over thermostat so thermostat not exposed to cool air which will cause thermostat to misread tank temperature.

C] Before replacing anything, you can test water heater parts and determine exact cause of problem. Testing requires $5 multimeter from Lowes or Home Depot:
Install battery in multimeter.
When test calls for testing voltage, rotate multimeter dial to 240 or 250 or 277 Volts.
When test calls for testing continuity, rotate multimeter dial to ohms (upside down horseshoe symbol is ohms)
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html
After doing 30 minutes of testing, you will be expert in water heaters.

D] You replaced elements for a reason
.
Did you test elements before replacing?
Was tank producing some hot water before you replaced elements?
If tank producing some hot water, then lower element was bad, and upper element was good.

And when you replaced lower element, did you also clean sediment out of tank?

If sediment builds up inside tank, it will reach lower element and burn out the element.
That could have been original problem, and it could be same problem again.
Restore full efficiency to tank by cleaning out sediment and replacing lower element.

Hot water runs out in 5 minutes it use to last 20minutes


Electric water heater can be repaired by homeowner.

Water heater has some hot water.
We know 3 things for sure:
- electricity is ok
- upper element is ok
- tank does not have overheating problem

Here are the suspects:
- Burned or loose wire
- Upper thermostat not working
- Lower thermostat not working
- Lower element not working

What to do:
1) Turn off power, open water heater covers and look for signs of burned or loose wire, especially on lower element. Burned wire on lower element says lower element is burned out.

2) Test lower element.
Lower elements burn out when sediment builds up inside tank.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html

3) If wires are ok. And you do not want to test parts, then replace upper and lower thermostat for 25$. If problem persists, replace lower element.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

4) If you want to test thermostats and elements before replacing anything:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

5) When finished, be sure to put insulation and covers back on tank so thermostats don't receive cool air and misread tank temperature. This will prevent overheating of tank that causes red reset button to trip.

My Reliance water heater suddenly produced only luke warmwarm water. I checked for power to the elements. Top one had nothing, bottom one had 110. I replaced the top element (which looked ok.) (power...


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.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

5) Final thing would be full troubleshoot:
