Question about Water Heaters

1 Answer

Water heater heats water and then cuts off. I replaced the lower element with a guaranteed for life element. It still heats up and cuts off. There is a control box on top that allows for an easy reset. Meanwhile the tenant is frustrated with having no hot water. The breaker never blows. There is power to the unit. it just needs to be reset.

3) Add a comment with more detailed information:
You have electric water heater.
Unknown brand, possibly energy-smart.
Unknown control box.
Cut off? Do you mean 'reset' is tripped?

4) Whirlpool energy smart requires 10 gauge wire and 30 amp breaker.
Control panel may not function with undersized electric supply.
Control panel has blinking-light errors ... if no error code then maybe the control box is bad.

SOURCE: Electric Water Heater Out

Have you reset thermostat on the heater, it will be the top thermostat right above the element. It will have a red reset button to press to reset. They will trip causing the heater not to work till it's reset or replaced due to thermostat gone bad. Chances are you may only have to reset it.

Please go to link below with to get some very helpful information on these topic's. If you replaced everything but the thermostat or reset it that's all left to hold out power to water heater. The thermostat is a safety device to protect the home owner. You may have had a element short out to trip it.
It will take 30 to 45 minutes to start to produce hot water after power comes back on.

SOURCE: My hot water heater tripped the circuit breaker on

Tough problem here. Most dual element heaters share one line. if this is the case and you have power on the top and none on the bottom I would check the connecting wires one to another. also check the settings of the thermostats. They may be adjusted all the way down. If the wires and connections are good I would recommend ohm testing the new elements. I have burned elements out by introducing cold water to very hot coils (forgetting to turn the water on after flipping the breaker)
Never forget that calcium buildup will short the element. If touching on the bottom you will burn it up.
If this does not help try borrowing hot water from neighbors ;)
Good luck

What if I replaced a long heating element with a short one on my water heater?


Won't matter much... except long elements generally burn out less often than short ones since heat is spread across larger surface area .. assuming both elements are same wattage.
Lower wattage element will heat water less quickly by a few gallons per hour.

Got 5 minutes of hot water then cold. replaced both elements and thermos. still 5 minutes of hot water. power bill increased nearly 400% in 30 days. HELP!!! please.


When the top of the tank is hot the upper thermostat removes power from the upper heating element and transfers the power to the lower thermostat and heating element. If the lower thermostat is defective, then the lower portion of the tank will not be heated and the supply will be greatly reduced. You replaced both elements however check that the lower element is coming on after ther upper one cuts out and is acutally working.
Check for power at the upper thermostat terminals where the power is sent to the lower thermostat and heating element. If there is no power then the upper thermostat should be replaced. If there is power then check for power at the lower heating element. If there is no power at the lower heating element then replace the lower thermostat.
If there is power to the lower heating element then it should be getting hot. If it is not, maybe defective. Another possibility is a broken dip tube. Check for a broken dip tube and replace if necessary.

If the dip tube is broken, the incoming cold liquid can mix with the out going hot liquid and cause it to seem as though you are running out.

LOWER ELEMENT IS NOT GETTING ANY VOLTAGE ON MODEL 65220RS


Short answer: Thermostats may be bad. Replace both thermostats.

Long answer:
1) If water heater has some hot water, then upper element is good and water heater has 240Volts, and best suspect is burned out lower element.
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

2) If water heater has no hot water because 240volt circuit breaker is tripped on one leg, and only 120Volts is arriving at water heater, then upper part of water heater can appear to have voltage and lower part of water heater can appear to have no voltage.

I am guessing this is an ele water heater and the temp setting are not the problem.
Problem: Not enough hot water or water temperature too low. When the top of the tank is hot the upper thermostat removes power from the upper heating element and transfers the power to the lower thermostat and heating element. If the lower thermostat is defective, then the lower portion of the tank will not be heated and the supply will be greatly reduced.
Check for power at the upper thermostat terminals where the power is sent to the lower thermostat and heating element. If there is no power then the upper thermostat should be replaced. If there is power then check for power at the lower heating element. If there is no power at the lower heating element then replace the lower thermostat.
If there is power to the lower heating element then it should be getting hot. If it is not, replace it. Another possibility is a broken dip tube. Check for a broken dip tube and replace if necessary.

The dip tub is located under the fitting where the hot water comes out.

The reset button has popped more then once.


You have electric water heater.
Electric water heaters are fully repairable by homeowner.

Reliance is AO Smith company
http://www.aosmith.com/OperatingUnits/Detail.aspx?id=138&ekmensel=c580fa7b_12_0_138_3
http://www.reliancewaterheaters.com/prod/elec.html

Age of Reliance water heater is shown on serial number located on side of tank:
first digit is letter. Next two digits are numbers: for example C06 means 2006.
Serial number also shows model number & wattage of elements in case you need new element from hardware store.

ECO reset button trips when upper thermostat senses temperatures higher than 150 to 180 degrees.
When ECO energy cut off trips, it turns off power at the reset button, so the tank does not continue overheating.
Tripping reset button says tank is receiving electricity, so we can eliminate that suspect.

There are 4 reasons why ECO will trip.
1) Bad upper or 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
2) Loose wire or shorted wire at or near upper thermostat: Open covers on water heater and inspect parts for signs of high heat and burning.
3) Bad element shorted to ground in center of element: Solution test elements and replace defective element.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html
4) Factory-installed insulation and cover has been removed from tank: thermostat exposed to cooler temperatures, and misreads tank temperature, and then elements keep heating water.

If you want to test all the parts before replacing anything:
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html


Thermostats are generic, and each functions same way and each can replace the other.
Same is true for both upper and lower thermostats

You can open the top up again. I would not turn the temp higher than 130 degrees, maximum. However, there should be above the thermostat a red button. This is where the power wires connect to the thermostats and heating elements. Sometimes this button needs to be reset, press it and discern if you hear a click sound. This means that the high temperature safety switch has tripped open and you had to manually "reset" it. There are two thermostats by the way. The water heater usually works this way. There are two thermostats and two heaters. The upper tank heater turns on first and it heats the top half of the tank. Then when the thermostat above is satisfied it then allows the bottom heater to come on and heat the bottom half of the tank. You might want to set the bottom heater thermostat as well. This is made this way because it is actually faster and more efficient to heat the top half first and the bottom half secondly. Try this first with the reset button. We could check voltages, but that requires a level of knowledge and safety that I am not sure that you are comfortable with. Pictures of the upper and lower thermostats and connections will help if the "reset" does not do the trick. By the way, not meaning or implying anything, but did you move the thermostat in the right direction? Sometimes the dials can be confusing.

Reset button seems to be stuck down and run out of hot water to soon


If I understand correctly, you have an electric water heater.
The water heater is dual element and has 2 access panels on water heater.
You run out of hot water quickly.
And the reset is stuck down.

First of all, if the reset button is tripped, the water heater will produce NO hot water.
The reset, or ECO (electricity cut off), is designed to cut off all power to water heater.
So if you have some hot water, then ECO reset is fine.
The thermostat may be bad, but the ECO is fine

Next in line:
If your upper element is burned out, then the water heater will not make any hot water.
So if you have some hot water, that tells us the upper element is working.

The three remaining suspects are upper thermostat, lower thermostat, lower element

Let's test the lower element.
Turn off the power.
Remove both wires from lower element.
Test across both screws with a continuity tester.

d18ee07.jpg
The continuity tester has a battery and when light comes on, it says the circuit is complete.
Test1) Test across both screws on lower element with continuity tester.
If the light comes on then the element is good so far, but element has to pass one more test.
Test2) Test each screw on element to any bare metal part of water heater.
If the light does NOT come on with the second test, then element is good.
Element has to pass both tests. Light ON first test. Light OFF second test. Then element is probably good. This is not a fail-proof test but it is a good indicator.

I'm betting the lower element is burned out and you need to replace lower element. And you may need to vacuum out the sediment.
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

Now if lower element is good, then the easiest thing is to do is replace both thermostats. After replacing both thermostats, the water heater will probably work. If there is still a problem, then the lower element was not as good as the test showed, and it should be replaced also.

Installed new upper & lower elements & thermostats, only top htr works


If original problem was caused by sediment burning out lower element, did you clean sediment out of water heater when changing lower element?
Two element water heaters are 240V.
Thermostats cut power on one hot wire, but 240V circuit has 2 hot wires. So lower element has power at all times coming from the red wire.
1) Use ordinary tester or multimeter set to 240V <> test each screw of lower element to bare metal part of water heater. Each screw should show 120V. If there is no power, then upper thermostat is defective, screw on upper thermostat is loose, or red wire between upper and lower parts of water heater is bad.
2) Remove wires from lower element. Use continuity tester or multimeter set to ohms <> test across both screws of element to see if power travels through element <> if element is bad, then continuity tester will not light up and multimeter will show no ohms. Put wires back on element after test.
3) Start with cold water in tank. Turn on water heater & upper element will turn on. Put ear on side of tank to hear if upper element is heating water. Test #3 screw to #2 screw on low left side of thermostat, should read 240V > Test #3 screw to #4 screw on low right side of thermostat, should read 0V.
Put ear on side of tank. When upper element turns off: Test #3 screw to #2 screw on low left side of thermostat, should read 0V > Test #3 screw to #4 screw on low right side of thermostat, should read 240V. If this test shows 0V and 0V, then upper thermostat is bad. If reading is correct, immediately move to next test.
http://waterheatertimer.org/images/Thermostats-numbered-divided-500.jpg
4) Turn temp on lower thermostat to 150. Using ordinary tester or multimeter set to 240V <> Test across both screws of lower element. If there is no reading, and you know element is good from step 2, then lower thermostat is bad, or wire is bad between lower element and lower thermostat, or wire is bad between lower thermostat and top part of heater.
5) Test across both lower thermostat screws, should read 240V.If this test is good, it means wires are good. Put jumper wire across both screws of lower thermostat, and test lower element again. If element finally turns on with jumper wire, then lower thermostat is bad.

If wire is bad between upper and lower parts of water heater, and water heater has tight-fitting 2" foam insulation, it usually indicates water heater replacement.

No hot water


If the water does not heat, then you have to troubleshoot to find the problem. With a voltmeter determine if 240VAC is actually getting to the water heater. Take care here - a defective circuit breaker can give a false 240 volt reading - check for the 240 volts across the upper element (i.e. when the 240 volts has a live load on it, not just an open circuit test).
Also, remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.
