SOURCE: need to empty reliance 501 hot water heater how?

1) Shut the breaker off to it at the panel. 2) Hook a hose up to it (the bottom has a drain). 3) Close the valve to the water heater (on the cold water supply). 4) Open drain on the bottom of water heater. 5) Open the relief valve to allow air into the tank (it won't drain otherwise - think if you put your finger on one end of a straw - the liquid stays in until you let go). Why are you draining it by the way?

There is an address near the end of this link to request manuals of reliance water heaters not listed. http://www.reliancewaterheaters.com/lit/om.html
it is quite possible that your heater works on the same principle as one of the other models and just differs in capacity or power rating.

Check the breaker and top thermostat and make sure they are not tripped. Move onto replacing elements if above is not the problem.
Turn water and power off to heater and attach a water hose to bottom of heater to drain down tank. May have to open hot side on a facuet to get it to drain.
Once drained remove elements with 1 1/2" found at local hardware stores. once elements removed and new ones in place. Turn water on and get the air out of the system. Once water is flowing from the hot side from all of facuet's in house.
Once all air is out now yaou are resady to turn power onto heater.

I wrote a page for changing water heater thermostat.
The photos take you through step-by-step
I recommend replacing both upper and lower thermostats so it eliminates thermostats as possible cause if water heater keeps overheating.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

The Reliance 606 manual shows your water heater uses generic upper and lower thermostats from hardware store.

Likely the thermostat will solve the problem:

50 gal. reliance electric heater. Water is getting way too hot and the settings were not changed. elements must be working for the water to be so hot. My guess would be the thermostat(s) since it won't...


Thermostats is in need of replacement and sounds like they are sticking. So it would be best to change both out. Turn power off to change them out it would be best for safety issues to change out as soon as you could. I have seen thermostats burn up in compartment on water heater.

We installed a brand new Reliance Electric Hot Water Heater, but no hot water, only lukewarm! Replaced top heating element and still no hot water!! Any suggestions as to what we need to do now?


If you have some hot water from dual-element water heater, then that tells us:
Water heater is 240Volt.
Upper element is working. If upper element is not working, then heater has NO hot water.
Reset button is not tripped.
Electricity and breaker to water heater are delivering 240Volts to heater.

Remaining suspects are:
1) Bad upper or lower thermostat: Solution: replace both thermostats for 28$.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
2) Bad lower element: Solution test and replace element:
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html
3) Loose wire or loose connection: Solution: open both covers and inspect for burning. Tighten all screws very tight.
4) Bad wire: Solution: Buy cheap multimeter from Home Center and do a 30 minute troubleshoot of entire water heater before replacing any parts:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html
When testing for voltage, rotate multimeter dial to 240-250-277VAC
When testing elements or continuity, rotate multimeter dial to Ohms.

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

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

6) Troubleshoot electric water heater
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

7) How to replace lower element and clean sediment out of tank:

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.

My water is not getting hot just warm


There can be a variety of reasons.
And there can be a combination of causes.
Does your tank have 1 access door or 2?
There is a heating element and thermostat behind each door.

The one thing we know for certain is that the upper element is producing some hot water.

The problem can be the thermostat.
For example if your thermostat is bad, that can cause the symptoms you describe.
If you have 1 element, it might be covered with sediment and ready to burn out.
If you have 2 thermostats, the lower thermostat can be bad.
The lower element can also be burned out
Or there might be 2 problems combined.

If it was my heater, I would test all the parts because I know water heaters.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

You many not want to test the water heater.
In this case, you can replace both thermostats and see if that corrects the problem.

Or we can work together over the next days or weeks and get your water heater working.
Set your schedule and add a comment when you need more assistance.

I have to press the reset button every day, what is wrong, thank you!!!


Thermostat is tripping out due to thermostat or element may be going bad. Also take a look at the element's wire's connected to them and make sure there are no burn places. Because the thermostat will trip out for safety of the heater.
The thermostat's and elements are not exspensive to replace. Please inspect them very closely and be safe.

If you replace the thermostat please turn power off and changing the elements turn water off.
If elements need changing fill heater and get all air out of lines before turning the heater's power on.
