Question about Rheem 80 GAL ELEC TALL Water Heater 6YR SC 82V802

1 Answer

My water heater thermostat keeps on tripping. I recently changed the temperature settings. I do not know if I increased or decreased the settings. What should I do. Due to this problem I switched on my second hot water system at night and in the morning I found the hot water coming out of safety valve pipe. I opened and closed the safety valve, the water stopped yet no hot water came to the taps. Does it mean that the outlet valve is blocked as it neither closes nor opens the threads are loose.

Hi .. if the thermostat is tripping and the safety valve is dripping , that would indicate that the water is being over heated , or the tank is at a low level . Check the thermostst setting, it should be about mid scale. Check the supply valve to be sure that there is a constant supply of cold water. Any thoughts?

Water heats up then trips off red button


The lit red button may be an indicator that the water temperature inside the water heater flow channel has become too hot. If the outflow facet is adjusted to allow more water outflow (opened more) the water temperature should drop some and therefore with increased water flow, the temperature inside the water heater will also decrease. Or, if there is a manually adjustable outflow valve on the water heater, adjusting it to a more open position would also decrease the internal temperature.

I have a 2002 atwood G6A-8E. It has been working well, however on the way home from a recent trip we heard a noise that sounded like pressure being realeased. I stoped and checked the release valve but...


Make sure you check back of water heater inside as well for any sign of water leak too. Pressure release may have been your city water hook-up as well, being it is a check valve too.
You have electronic ignition, and the temperature is regulated by the thermostat, below the pressure relief valve, which is pre-set. It simply sits against tank and when water reaches set temperature at that point , it shuts it off. Beside that is an ECO , (emergency cut off) that looks the same but is set at a slightly higher temperature, in case the thermostat malfunctions. There is a possibility that your thermostat is malfunctioning, and it's shutting off at the higher temperature. I'd replace both thermostat and ECO, as they usually come as a set and aren't overly expensive. You'll see the white letters on dark foam cover. THERM, AND ECO. Just carefully peel it off and you'll see how to change them. Make sure springs and retainers go back on the way they should in order to keep them up against tank properly. There is a thermostat available with a little cooler temperature if you prefer.

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

Hello, i have a reliance 606 im having a problem that the reset button, it keep on tripping. when i reset it last like 2 days then it trips again. i have changed the upper thermostat and element and it...


It sounds like you have things pretty well covered. I would change reset and if it continues to trip breaker I would check wiring very carefully where it enters top of water heater. Check for any nicks or bare spots on wiring insulation. Other than that about all I can think of is to change breaker. Sometimes they do get weak and trip to easily. Hope this helps. Thanks

The red button keeps poping causing the hot water heater to shut off. I have to constantly reset it.


The red reset button or ECO or energy cut off turns off power to electric water heater.
The ECO responds to temperatures in excess of 150 degrees F.

Preliminary work:
You can use thermometer to check water temperature immediately after ECO trips.
Compare water temperature against the thermostat setting.

There are 4 things that can cause ECO to trip:
1) Bad thermostat is sticking and letting element continue heating water, or ECO is reading incorrect temperature.
2) Factory installed insulation and cover missing from tank, and thermostat is exposed to cooler air and misreads tank temperature.
3) Element shorted to ground in center of element. This completes 120V circuit to ground which will cause element to continuously heat the water.
4) Loose wire near ECO causing high-heat electrical event.

Solution:
Check for missing insulation.
Check screw terminals for signs of high heat and burning >> tighten screws.
Replace both thermostats using detailed instructions given on link below.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

If the problem continues after replacing thermostats, more troubleshooting is needed:

Water heater will not work unless i push reset button will work for 24 hours or so then will stop working and i have to go out and reset it


The reset button or ECO (emergency cut-off) is a safety device.
The ECO trips and cuts off power to entire water heater when it detects temperatures over 150 degrees.
This prevents overheating and eventual explosion of water heater.

The ECO will trip for 4 possible reasons:
1) Bad thermostat. Water temperature inside tank exceeds 150 degrees F because thermostat is sticking in ON position, and thermostat does not turn off element correctly.
2) Loose wire inside or near upper thermostat that causes ECO to sense higher temperature
3) Bad element shorted to ground near center of element, and short does not cause breaker to trip
4) Factory-installed insulation and cover are removed from water heater >>> cooler air causes thermostat to read wrong temperature, and thermostat keeps heating water inside tank

Steps you can take:
First thing is to check if factory-insulation-and-cover are present.
Next look for signs of burning at or near screw terminals. Tighten loose wire if found.
Especially check the lower element screw terminals.
Take a photograph of the parts so you can see the parts larger on your computer, and compare parts more easily when buying new parts.
Next most likely suspect are the thermostats.
For around $22, you can buy generic upper-and-lower thermostats at Lowes or hardware store > then replace the thermostat(s) and see if problem persists.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

If problem continues after steps above
You will need to test water heater parts to track down the exact problem:
You need a inexpensive multimeter from Radio Shack, and the steps are simple, and you will know everything about an electric water heater afterward.

Rheem Hot Water Cylider Thermostat keeps tripping


Sounds like you have a faulty thermostat.  This is the unit that detects the water temperature, and if it is not where it is set, will kick the switch to allow electricity to flow to the elements you replaced. The thermostats are relatively cheap and if you have the knowledge to change the elements, changing these thermostats should not be a problem.
