Did you turn the breaker on ? before filling the tank ?the water tank must be completly full before turning on. the new elements will blow if not submerged in water ..if you have 240 volts at the element and its not heating one is out .only one element can be on at a time so you really need an amp prob to test element .try an ohm meter an check resistance ,sounds like one element is out .hope this helps good luck /P/Swhen filling tank. open a hot water valve, on tub or faucet to remove air while filling the tank. you will hear the air coming out of faucet. when water comes out its filled..

Just re[placed the upper and lower element on our hot water heater. That was three hours ago. the water is still cold.


Push in reset button located on upper thermostat.
Push circuit breaker fully off and then fully on.
Make sure tank is filled with water before turning power ON or elements will burn out

Reliant 40 gallon tall electric water heater replaced both thermostats upper and lower elements flushed tank hot water very hot temp turned down lowest possible keeps tripping reset button what else could...


Problem has to be bad element or bad thermostat.

Test elements for short to ground through metal tank wall:
http://waterheatertimer.org/How-to-test-water-heater-element.html

Make sure factory-installed insulation and cover are re-installed over new thermostats so they do not misread tank temperature.
If problem does not show with elements, then replace thermostats again.

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.

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.

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.
