Here's an article detailing electric water heater repair, that will be helpful to you.

Generally, when the reset button must be activated repeatedly, it indicates that one of the thermostats is not working properly. It is failing to sense the the actual temperature of the water in the tank.

This may be caused by a number of different things with the more likely being a defective thermostat, water damaged thermostat, poor contact of the thermostat with the tank itself (this can be due to rust build up between the two or insufficient spring pressure holding the thermostat against the tank).

You should do a visual inspection of the thermostats (with the power off!) to rule out the poor spring pressure, presence of rust or water and water damage to the thermostat. Repair sources of leaks if possible, remove thermostat(s) to clean the mating surfaces behind it and replace thermostats / parts that are weak or bent (in the case of the spring clip); wet or show evidence of earlier water damage.

Once the thermostat(s) can properly detect the rising temperature of the water being heated by the heating element again, it will shut off power to the heating element when the water matches the temperature you have selected. When the thermostat is unable to accurately determine the water temperature due to poor contact with the tank, the thermostat will continue too allow power to flow to the heating element - causing the water temperature to rise significantly higher than the level selected. This is when the high temperature switch operates to prevent the water from being heated any more. Needless to say, scalding is a very real threat any time the heaters continue to heat the water to a temperature higher than 140 degrees.

I hope this helps & good luck!

The water heater breaker keeps tripping and I have to reset it to get hot water. It continues to be a problem, what should I do?


Thermostat could be bad causing the breaker to trip due to it being shorted. It's either your breaker or the thermostat, more than likely the upper thermostat is bad.

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-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.

WHERE IS THE RESET BUTTON ON THE 6EM30-2 FROM AUG 2004?


Electric water heater has panels located on front of water heater.
Remove top cover, and insulation to reveal thermostat and element.

Stand on dry surface, including boards or plywood.
Do not hold screwdriver in mouth.
Do not touch any metal.
Red reset button is located on thermostat.
Push in reset.
If reset will not re-engage, then thermostat may be bad, or some other problem exists.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Screw terminals on thermostat are live.
When finished, insulation and cover must be put back over thermostat so thermostat not exposed to cool air that will cause thermostat to misread tank temperature.
Put ear against tank to hear bubbly-fizzing sound that says water heater is working.

If water heater is leaking or wet, do not touch unless circuit breaker is turned off.

Electric water heater is fully repairable by homeowner.
ECO red reset button trips when upper thermostat senses overheating.
You many have underlying problem if reset continues tripping:

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.

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

HELLO, MY WATERHEATER KEEPS TRIPPING THE RESET BUTTON ABOUT TWO TIMES A MONTH. WHAT COULD BE THE PROBLEM?


could be faulty thermostat/reset button, or shorted element. Breaker to water heater off,
Check elements for continuity to ground. should be no continuity to ground. If elements OK replace reset button. If you have noticed very hot water and elements checked OK then replace both thermostats along with reset button

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:
