The top element only comes on when the heater is about out of water. The water is directed to the bottom of the tank. Cold water stays on bottom, Bottom heater element heats water. If you use all that water then the top of the tank gets cold and the top element comes. When the top of the tank is warm, then the bottom element comes on. I would susupect the bottom element as it does most of the work. If you have an ohm meter, turn off electric, and remove wires from element. Check element for continuity. If you don't get reading, then that element is bad.

How to replace the Thermostat and Element for Electric Hot Water Heater


If you are having a problem with your electric hot water heater then you may also wonder if you can replace the failed part. The short answer to this is yes! The replacement is easy enough that most any handy person can easily perform this task.

First off make sure that you remove all power to your electric hot water heater. Then remove the access covers that cover the thermostats and the heating elements. After performing the required diagnostic tests to find the fail part you can then concentrate on the part removal and replacement. Check the tips at the bottom of this one to see how to trouble shoot your hot water heater.

To replace the heating element you may have one of two styles of element. One style has a four bolt flange that holds the element in and the other has threads that hold it in.


Before removing an element make sure that you shut off the water and drain the tank to a level below that of the element that you need to replace. This will keep you from making a mess and possibly hurting your self with the hot water.

For the four bolt flange type element, you simply remove the two wires from the element and then turn out the bolts from the flange. Once the flange is off the element will just pull back and out of the hole.

Replace with a new element and gasket. Make sure that the new gasket gets seated in the hole to seal the element when you tighten down the bolts on the flange again. The bolts do not need to be super tight. Just snug them up good and then fill the hot water heater with water to check for leaks and then tighten more if necessary.

For the screw in elements, a removal tool is a good idea.
506a25d.jpg
605c00e.jpg
A large socket looks like it would work, but because of the thinness of the hex part of the element and the bevel on most large sockets, it is very difficult to get them to grip the element securely. Most hardware stores or home centers sell a very inexpensive removal tool that works very effectively. It is well worth the effort to get the proper tool to do the job. To remove the screw in element you need to turn the element to the left or counter clockwise. Then make sure that you do not cross thread the new element as you turn in clockwise or to the right and tighten it in. Once again, make sure the gasket is seated correctly and do not over tighten. Re-hook the wires after leak checking the tank and replace the cover before energizing the electric hot water heater.
c665c2c.jpg
To replace either the top or bottom thermostat, you also need to de-energize the hot water heater and remove the cover. When removing a thermostat it is a very good idea to mark the wires and the position where they were on the old thermostat. This makes the re-installation of the new thermostat easier. The old thermostat is held tightly too the tank so that it gets a good reading on the tank temperature. Be careful not to bend the bracket that holds the thermostat when you remove the old one. If you do not have the new thermostat making good contact with the tank it will not operate correctly and give you too hot of water. After switching the old thermostat with the new one, replace all of the wires to their correct position, replace the plastic, and the cover before energizing the hot water heater. Both the top and bottom thermostats are similar in their replacement, but the top thermostat also incorporates a safety reset control and switches power to the bottom element when the top of the tank is hot enough, so there a re a few more wires to that thermostat. This also keeps the two thermostats from being interchangeable. You cannot install a bottom thermostat or the top or a top one on the bottom.

This whole process is not as complicated as it may seem and you can do it!

Electric Water Heater not Working


If you have an electric water heater and it is not making any hot water then you have a problem. The good news is that electric water heaters are not that hard to troubleshoot and there are not a lot of things that can go wrong with them. I will go over the things that can give trouble and how to fix them.

First off if you have some hot water but not as much as you did when it was new then you probably have a bad bottom element. Only the top element is working, so you are only getting about 1/3 of a tank of hot water, replace the bottom element and you will be good again.

If you are making steam, then you have a bad thermostat. While you are making the steam out the relief valve, check to see which element is working. The easiest way to do that is to see which element has 220v on the two screws on the element. That thermostat at that element is bad. Replace it and you will stop the sauna.

If you have no hot water then check the red reset button directly above the top thermostat. You may have to push very hard on it to get it to reset. If the reset is tripped then you have a bad thermostat. Finding out which one can be tricky and timing is important to catch the bad thermostat in the act.

No hot water can also be the result of the top heating element going bad. If the top element goes bad then the top thermostat will never get enough heat to trip on the bottom thermostat. Therefore you will get no hot water. Dual element hot water heaters for residential use, do not ever run both elements at the same time. Only the top OR the bottom will be energized at a time.

This all there is to checking an electric hot water heater. If you are having problems go through this list systematically and you will find your problem and be able to fix it.

Water heater


Guessing that you have 240Volt residential non-simultaneous electric water heater? And that you have 30 amp breaker and 10 gauge wire. And that water heater is located within 100 feet of breaker box. And there are no leaks running hot water out of tank. And that you installed fully brand NEW elements of same wattage as old elements. And that fully brand new thermostats were installed, and wiring exactly duplicates wiring that was present before. And that factory-insulation was re-installed over elements and thermostats.

1) Guessing the 'hot water shut off' means the ECO red reset button located on upper thermostat keeps tripping and cutting off electric power to water heater?
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html
http://waterheatertimer.org/images/WH-w-combined2-1000.jpg
http://waterheatertimer.org/How-to-test-water-heater-wires.html

2) If the ECO is tripping, then water is getting too hot, or there is shorted wire located near the upper thermostat, .
Typically replacing both thermostats and replacing elements will solve this problem .... assuming that new thermostats and elements are good, and wiring correct.
Double-Check your wiring on upper and lower thermostats.
Test wires for short.
Make sure factory-insulation is re-installed over thermostats so cool room temperature will not affect temperature reading.
Check that thermostats sit flat against steel tank.
Many short draws hot water can also cause stacking event that will trip circuit breaker.

3) Add comment and say what you find using checklist above.
Be careful to explain findings fully, using same words found on links above, so illuminated diagnosis can be made.

Replace overflow valve to end the drip.

If tank type water heater has some hot water, then upper element is receiving 240V and electric circuit can be eliminated as suspect.
Lower element or shorted wire to lower part of tank or upper thermostat not wired correctly are next suspects. If plumber replaced the parts the wiring will be correct, but he may not have checked for shorted wire.
If the elements were replaced but sediment was not cleaned out of tank, then that can also cause the problem you describe: the new lower element is shorted out because its stuck in the sediment or no water is circulating around the new element.

What to do if water doesn't get hot even though I have increased the thermostat settings... the heater isn't even4 months old and it has done this from day one


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.

A) If your water heater receives very cold incoming water, it may not heat fast enough to keep tank warm.
Add a tempering tank.
http://waterheatertimer.org/Tempering-tank.html
Add insulation over entire water heater except TP valve. Insulate pipes completely.
Read more information:
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html

B) If cold outside temperatures are not to blame, your water heater may have a bad thermostat or element.
Narrow down the suspects:

Water heater is 240Volts since you have more than 1 thermostat.
Water heater has some hot water.
This tells us upper element is working.
And that water heater electricity is working.
And that reset button is not tripped.
And that heater is not experiencing run-away overheating event.

That gives us 3 solid suspects.
1) lower element is burned out. Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:
This will restore water heater to full 99% efficiency.
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

2) Upper or lower thermostat is bad. Replace both thermostats for about $25.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
If you want to test thermostats and all parts before replacing anything:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

3) Burned or shorted wire. Turn off power. Open covers on side of tank. Remove insulation. Inspect parts for signs of high heat and burning. Especially lower element. Tighten any loose wires. Replace part that shows signs of burning.
Put insulation and cover back over thermostats so cooler outside temperature doesn't cause thermostat to misread tank temperature.

I just installed a water heater about 11:00 am today but still do not have hot water what could it be


1) Many times people turn ON the electricity before the tank is filled with water.
This instantly burns out any element that is not submerged in water.
If the upper element is burned out, the lower element may be good, but the way the thermostats work, the upper element must heat top of tank before power is sent to lower element.
http://waterheatertimer.org/How-to-test-water-heater-element.html

2) My new electric water heater had same problem, and the red reset button, or ECO, was tripped on upper thermostat.
Open cover and check reset.

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.

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.

Water Too Hot


needs new thermostat(s) If the whole tank is heating( next time it trips, before using any hot water check the lower tank thru the lower element access(breaker off) If the lower tank is hot-you need a new lower thermostat. if just the upper part of the tank is heating -you need an upper thermostat.
