In the United States, Honeywell makes many products in and out of the home, From motion detectors to navigation systems for airlines. Honeywell also makes water heater control valves that are used on several water heater brands.
When faced with a hot water supply issue, the first troubleshooting step is usually to reset the unit. But frustration ensues when you cannot figure out how to get that done.
I had the same frustration as you do when trying to locate Honeywell water heater reset button.
But it is important to note that manufacturers make reset buttons hard to access to prevent accidental activation.
This article will show you how to activate the Honeywell water heater reset button system.
The Reset Button on the Honeywell Water Heater is the pilot light knob. You can reset the water heater by lighting the pilot and turning the knob to “very hot” for ten seconds, “hot” for ten seconds and to “pilot” for 10 seconds. Your code light will begin blinking normally
Most water heaters have a reset button which is usually found underneath a metal cover in the middle of the water tank. The Honeywell Water Heater is different in this regard.
How to Reset Your Honeywell Water Heater
When you arrive at your water heater, you will notice that the code light is either blinking abnormally or permanently on, indicating that there is a fault.
You can reset your Honeywell hot Water heater in four steps.
- Head to you hot water tank and make sure that the pilot light turned on.
- Turn the pilot light knob to the “very hot” position for 10 seconds.
- Turn the pilot light knob to the “hot” position for 10 seconds.
- Turn the pilot light knob to the “pilot” position for 10 seconds
At the end of this sequence, the pilot light will begin blinking again.
Why is My Honeywell Hot Water Heater Tripping the Reset Button?
Honeywell designs its heater reset buttons to trip as a safety precaution. When the water temperature rises in an uncontrolled fashion, the reset button is tripped.
Here are some reasons why the reset button may trip.
Bad Heating Element
The heating element is responsible for raising the temperature of the water in the tank.
If it is damaged or has a short in it, the temperature of the water will continue to rise. This triggers the reset button to trip because it is unable to communicate with the thermostat.
To resolve this issue, a replacement heating element may be required.
The thermostats in the water heater are responsible for monitoring the temperature in the tank.
It operates by delivering signals to the heating element, which either turns on to boost the temperature or turns off to lower it.
If the thermostat fails, it is unable to perform its function, causing the reset button to trip since there is no communication between the thermostat and the heating element.
Electrical Problems (Bad or loose Wiring and Circuit breakers)
Electrical issues are a common cause for the Honeywell water heater’s reset button to trip. I normally start by looking for faulty wiring and damaged circuit breakers.
The reset button might be tripped by loose wires. In many circumstances, you can see when there is an issue with the wiring of your unit’s components. You may find burnt pieces, or when you delicately pull on a wire, it may entirely detach from the component to which it is attached.
Circuit breakers deteriorate as they age as well. When you open your electrical panel, you may notice that they are hot to the touch, and you may even smell burning.
Checking for and removing electrical problems as a possible reason of your unit’s reset button tripping is an important step in the troubleshooting process.
What setting should my Honeywell Water Heater be on
Your Honeywell water heater should be set at a temperature of 120 degrees Fahrenheit. This is the temperature recommended by the department of energy.
This temperature maximizes the balance between what is needed for most home uses and controlling your energy costs. The hotter the temperature, the more energy is required to maintain that temperature because your water heater will need to cycle on and off more frequently.
Honeywell Hot Water Heater Control Settings
The Honeywell Water Heater has the following Temperature Settings
|Very Hot||160 degrees|
One thing I have noticed is that the temperature setting at the water heater can be very different from the temperature at the point of use. Heat losses can occur all through your piping system. It is important to keep this in mind and use a thermometer to determine if the temperature is where you expect it to be.
How to Turn Up Honeywell Water Heater
The Honeywell Control Valve has three settings, A, B, C on the pilot light knob to control the maximum temperature of the water heater.
To change the maximum temperature on the water heater, turn the dial up from A to B or to C. It is important to wait for at least 30 minutes for the switch in temperature to take full effect. It takes the heating elements that much time after the dial is adjusted to heat up the water that is in the tank.
Does a Honeywell Water Heater Thermostat Have a Battery
No. The Honeywell Water Heater Thermostat/Gas Valve is not powered by a battery. The thermostat is powered by a thermocouple. The thermocouple works by converting heat it generates in to electricity.
The heat is generated as a result of the deferential in conductivity that occurs within the thermocouple. That differential causes electrical current to flow which in turn powers the thermostat.
Honeywell Water Heater Reset
Resetting your Honeywell Water Heater is relatively easy once you realize that there is no reset button. Make sure that the pilot is turned on, switch the dial to “very hot” for 10 seconds, to “hot” for 10 seconds and to “pilot” for 10 seconds. This will reset your water heater.
