FAQs

Does a water heater have two reset buttons?

No, not every water heater has two reset buttons. But every tankless water heater from Stiebel Eltron comes with two thermal safety reset buttons.

What happens If I push the reset button on my water heater?

The reset button is basically a safety device on a water heater. This button gets tripped when the water temperature exceeds the safety level or reaches 180F. In this case, you need to reset the button manually to get the water heater back to its normal operating condition.

Should I hit the reset button on my water heater?

Yes, you should hit the reset button if it gets tripped to bring the water heater into its normal operating state. However, I don’t recommend you to press the reset button if the unit is functioning in its tip-top condition.

How long should I wait after resetting water heater?

It depends on the type of water heater you own. If you have an on-demand water heater, you will get the hot water instantly after resetting the unit.

However, you will get warm water within 30-40 minutes if you own a gas-operated tank water heater. At the same time, an electric tank water heater will take up to an hour to deliver hot water after resetting it.

What causes hot water heater to trip reset button?

The water heater generally triggers the reset button when the water temperature inside it reaches 180 degrees F. By tripping the reset button, the unit shuts the power off to the unit to avoid further damage.

In short, overheating is the main culprit that causes the unit to trip the reset button. Typically, the unit overheats the water when the heating system gets clogged by dirt or debris. 

That’s why you should flush the water heater every six months to per year, depending on the condition of your supply water.

End-Note

So, follow the instructions I mentioned above and get the safety cutouts reset successfully.
