I have a Reliance 606 water heater that no longer provides hot water. Any ideas?


the heating element has most likely burned out (if its electric) if its gas then look to see if it is lightinng. if electric, the element is easy to replace and not very expensive.

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.

I'm getting hot water for 2 minutes , then it gets cold


Most electric hot water heaters have two thermostats, one near the top of the tank and one near the bottom, and are covered by removable metal cover plates. The thermostats are pressed firmly against the bare metal wall of the hot water heaters tank.

The top thermostat usually has a high limit switch that will trip if the water gets too hot. When it trips it shuts off the electricity to both the upper and lower heating elements.

To reset the high limit switch there is usually a red button that you must press. When the upper limit switch trips it is often an indication that something else has gone wrong with the heater.


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.

Hope this helps out

Replaced bottom element and both thermosats. the reset button tripped what would cause this to happen


Reset trips when upper thermostat senses high heat event over 150 degrees F.

High heat can be caused by:

1) Element shorted to ground through center of element. Thermostats turn off one leg of 240V circuit. Elements always have 120V available. If element is shorted to ground, it might not trip breaker, and continues to heat using one leg of 240 with circuit completed to ground wire.
Test elements:
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html#120-240

2) Insulation and cover not put back over thermostat. Thermostat exposed to cool air, misreads temperature causing element to continue heating.

3) Thermostat sticking in ON position. I usually replace both thermostats at same time to save another trip.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

4) Shorted wire or loose wire at or near upper thermostat. Check that screws are very tight against copper wire.

5) One suspect can be eliminated is 240Volt power to heater.
Your heater circuit is good.

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

Rheem 83xr52-2 50 gal residential water heater. Water temp was low. I cut power at electric panel, removed upper panel on water heater, turned up thermostat, replaced panel and switched power back on at...


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.

I have a model 71-408 B which just stop heating


If I understand correctly, you have electric water heater.
Heater suddenly stopped heating.

Four things cause sudden loss of water heater.
1) Reset button located under the top cover is tripped > turn off power, remove cover, press reset button > if reset keeps tripping, go to the troubleshooting link shown below.
2) Electric power to heater is interrupted > check circuit breaker > test for voltage > look for loose wire on breaker
3) Upper element burned out > test and replace element
4) Upper thermostat bad > replace upper thermostat

Reset button is best suspect.

Lochinvar electric hot water heater reset button


Is this a two element 220 Volt heater? Do you know how old the elements are?

I have a feeling your elements need to be replaced.

What are your thoughts on my remarks?

My reliance electric waterheater wont shut off.i replaced both upper and lower themostats. it runs till it trips the reset switch.sounds like the upper element still running after lower shuts off


Test elements for short to ground.
Element that is shorted in center might not trip breaker.
Because thermostat only turns off one leg of 240V circuit, the element will continue heating using 120v to ground:
