Can the heater be reset?

Why Does My Electric Water Heater Reset Button Keep Tripping? So the red reset button on your electric water heater keeps popping out and needing to be reset.
Here's the most likely problem: The water in your water heater is getting too hot.
When the water temperature in your water heater exceeds 180°, the red reset button (also known as the high-limit switch) trips. This tripping protects you from getting scalded or burned when using hot water in your home.
OK, but then what's causing the water in your water heater to get so hot? The most likely cause is a bad thermostat.
How a bad thermostat causes your water heater reset button to trip Electric water heaters have a lower and upper thermostat-one for each heating element.
The thermostats are responsible for controlling the heating elements. When the water has cooled off, the thermostats kick on the heating elements to heat the water. And once the water has reached your desired temperature, the thermostats shut off the heating element.
(This is very similar to the way your heating and air conditioning thermostat controls your home HVAC system.)
But these thermostats can go bad. When they do, they sometimes get stuck in the "on" position. This means that that the heating element continues to heat your water, eventually causing the high-limit switch to trip.
The fix: The bad thermostat needs to be replaced. A plumber can use a multimeter to test the thermostats and find out which one is bad.
Other problems that can cause your high-limit switch to trip While a bad thermostat is the most common reason your water heater's reset button may trip, it's not the only one. Other common causes include:

• A shorted heating element-It may be that the thermostat is working just fine and shutting off the heating element. But a short in the element is causing it to continue to heat your water.
• Loose wiring-A loose wire in the water heater can generate heat that can cause the high-limit switch to trip.
• Bad high-limit switch-The switch itself may be malfunctioning and tripping when it shouldn't be.

"Resetting the Temperature Cutoff Switch

This unit is equipped with a thermostat which controls the temperature
of the room by turning the heater on and off. The heater is protected
with a safety device to prevent overheating. Should the heater
overheat, an automatic cut out will turn the heater off and it will not
come back on without being reset. It can be reset by switching the
Main On/Off Switch to off and waiting five (5) minutes before switching
the unit back on."

try jumping out the pressure switch see if it lights , or first unplug heater and replug in might reset or it could need a clean

Hi

If clean light is blinking 7times then please reset the power to the dishwasher. After, 5 minutes check if you are still getting the same error. If yes, then it is a water heating fault. To resolve this error try pressing this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air Dry - High Temp - Air Dry.

If this doesn't work then its an issue with the heater circuit, door switch, wash pump not pumping the water past the heater efficiently or due to lack of water to heat. Please make sure that heater is not open circuited and is heating the water efficiently. If heater is fine then make sure water pressure is optimum and fill valve is working fine.
Hope this helps... If it does please do not forget to accept the solution or post back for assistance.

Do you have power to the heater?If you do then I would look for a hi limit switch to reset.It might be the pump you have to reset.

check the power to the relay and pressure switch just remember the problem lies where the power dies.

the thermal resister between the two reset breakers on the bottom is what the problem with mine was
