Replace heat trap nipples or inserts?
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#heat-trap
Factory Heat traps save $2-$9 per year but can cause noise, and you can make your own heat traps.

Electric water heater is probably the only household appliance made today that can be maintained and repaired by homeowner to last almost indefinitely. Certainly no other water heater can last as long, even with maintenance.

SOURCE: I have an AO Smith Model EES 52 917 hot water

You have electric water heater.

Inside the upper panel on water heater is a thermostat with red reset button.
1) Click the reset.
2) Put insulation back over thermostat so it is not exposed to cooler air, so it reads correct temperature.

After resetting thermostat, you will have hot water.
The reset automatically clicks off when thermostat detects temperatures in excess of 150 degrees.
The re-set is a safety device, and it keeps everything safe.
If reset will not 're-set' with cold water in the tank, then thermostat is bad, replace thermostat.
You can repair electric water heater yourself following steps on links below

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

If the reset clicks off again, just reset it
This is not a dangerous situation
Reset thermostat as many times as necessary until you can fix the problem

If you have trouble fixing the problem, add a comment at bottom of this page and it sends me an e-mail and I will help further

SOURCE: MY HOT WATER COMES OUT

A new water heater may not solve the problem - do you have colored water coming out of the cold side, at all faucets and in your commode too? If so then your pipes may be corroded inside ( typical from well water systems) and will need replacement too. Initially I would suggest hooking up a garden hose to the drain on the heater and, after running the other end of the hose outside, open that valve to see if the water is colored. If so, then I would strongly suspect your water heater needs replacing. Also, look under the water heater to see if there's any leakage, indicated by brown stains either on the floor under the heater or running down the side.

SOURCE: want to replace 17 years

If I understand the wording on the max rebate you will need to go with one of the high effiency on demand heaters such as bosch or whirpool .There are several more manufactures that will qualify for up to 1600.00 on taxes and some dealers offer there own incentive programs. Most of these heaters are going to cost in excess of 2000.00 plus installation but they will save operating expenses. Hope this helps. Thank you

AO Smith is biggest manufacturer and ships about 140,000 units per month sold under different brands. Look at rating on tank. Is it a 9 year tank? Or 6 year? Or lifetime?
http://waterheatertimer.org/Water-heater-manufacturers.html

Number of factors can cause rust around element:

1) Element is seeping moisture: check and replace element.
Elements can start leaking any time
http://waterheatertimer.org/Water-heater-is-leaking.html

2) Anode rod can be depleted from variety of factors including water softener or calcification over anode so it will not work: Check and replace anode rod every 1-2 years with water softener, every 3-5 without water softener. New anode rod will STOP the rust, but will not repair tank that is rusted.
Tanks with longer warranties have 2 anode rods, one on hot water nipple, the other on top of tank.
http://waterheatertimer.org/Replace-anode-rod.html

3) Stray current corrosion: add a jumper wire between hot and cold pipes, and make sure tank is grounded. If there is stray current, it will deplete steel in tank if tank is not grounded.
For example one fellow had a tank that rusted out every few years until he discovered his big radio antenna was grounded back to hot water pipe and the tank was not grounded, so the interference depleted his tank.

SOURCE: I have an AO Smith

The water that is leaking, more than likely, has gotten into where the electrical hook up is, Yes, that is the electrcal hook up. There also should be a ground under or attached to that flap. Be very careful, this is 220v. I would make sure the breaker, fuse is out before you go poking around more wires. You should have a panel(s) on the front of the heater help on by screws, take them off and see if it is wet in that area. With water in the pan also, the water could be leaking down inside the metal tank, which could short out the whole heater. The haeter is grounded so that in the event that water and electric make contact with the metal housing, it should pop the breaker. You, among other things may not have a good ground which is dangerous. Anyway if all seems dry around the elements and thermostats, you may have a bad element or, if you have two elements, you may have to reset the thermostat by pushing the little round red button. You need to take care of the leak but, if you know how, check the heater out and, if its all rusty, etc., you might ought to repalce it.

We aare in a home unit with a Rheem 80 gallon electric hot water system installed JANUARY 2011 it and it has issued terrifyingly loud rumbling noises. When I pulled the pressure release lever i t...


1) The pressure release valve is operating correctly and the sound it made is typical.
So pressure release is okay.
Always protect yourself from very hot water that can spray out of pressure release.

2) Rumbling sound is typical sign of sediment build-up inside tank, and usually indicates that tank needs to be cleaned out.
Seems odd that a brand-new tank could have sediment after only 8-9 months.
Did somebody recycle a 'new-looking' heater and sell it as 'new' heater?
Look at label on side of tank, and find brand and serial number to find actual age of water heater:
http://waterheatertimer.org/pdf/WaterHeaterSerialNumberDecoder.pdf

3) Because sound might not be sediment.
You can add a comment and it will send e-mail, and I will continue to answer.
No reason to be terrified of water heater. They are very safe, and homeowner can fix electric water heater same day for a few dollars.

4) Please listen to exactly where sound is coming from.

5) If sound seems to come from the pipes, and pipes are vibrating, then the plumbing is suspect, for example a check-valve, or pressure valve, and we can talk about that when you add a comment.

6) If sound is from inside the tank, then I suggest you turn off power, let water cool, drain water heater, open bottom of water heater, remove element, and check for sediment.

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

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 have a Reliance 501 water heater, when I take a shower now I only get about 5 min. of hot water is there something on the heater I have to reset? Thnx Mike


Electric water heater is fully repairable by homeowner.
Following information will tell you how.

1) Background on your heater:
Reliance is AO Smith company.
http://www.aosmith.com/OperatingUnits/Detail.aspx?id=138&ekmensel=c580fa7b_12_0_138_3

Age of water heater is shown in serial number. First character is letter. Second 2 characters are numbers, which are year of manufacture. For example 05 is year 2005.

The 501 manual is not shown on Reliance website:
http://www.reliancewaterheaters.com/prod/elec.html

2) Two things known for sure:
- electricity is OK
- upper element is working because there is some hot water.

3) Three things can cause problem you describe:
- Loose wire located from upper thermostat to lower element and thermostat.
- Upper or lower thermostat is bad
- Lower element is burned out

4) How to troubleshoot and repair
- Turn off power, open covers and look for loose and burned wiring, especially on lower element.
- When finished, put back insulation and covers so thermostat not exposed to cooler temperatures.
- Burned wire on lower element is evidence that lower element is burned out.

- If you do not want to follow testing steps below, next step is to replace both upper and lower thermostat for about 25$ and see if problem persists.
- If problem persists, replace lower element.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

5) Test lower element, before replacing anything
http://waterheatertimer.org/How-to-test-water-heater-element.html

Reliance is an AO Smith company

http://www.reliancewaterheaters.com/prod/elec.html
Link above goes to Reliance electric water heaters
I cannot find your model number
The serial number seems to show it was made in 1994, so the spec sheet would be difficult to find
You must have bought a good heater and taken care of it for it to last that long.

http://www.reliancewaterheaters.com/lit/spec/electric/R606E0510.pdf

Typical 40 gallon Reliance electric:
18" x 59-1/2"
20-1/2" x 44"

http://www.reliancewaterheaters.com/lit/spec/electric/R909E0510.pdf
Self-cleaning type Reliance 40 gallon
19" x 60"
21-1/2" x 46"

The size of your heater can be determined by measuring the height, and then measure across the top to get the diameter. Your measurements will be close to the numbers shown above.
