Girard Tankless Water Heater Reset Button [The Ultimate Guide]

While operating the Girard tankless water heater, users encounter several issues that require just resetting the unit to resolve that problem. But when you’ll head to find the reset button, it’s quite obvious that you will get confused about whether the unit equips a reset button or not.

Thus, before moving toward the resetting steps, it would be better to figure out the location of the reset button on your Girard tankless model. 

Where Is The Reset Button Of The Girard Tankless Water Heater?

While operating your Girard tankless water heater, I bet several times you might be wondering about the reset button location on your unit. To be truth, there isn’t any built-in button on the remote controller that can be regarded as a reset button. 

But wait!! There is a mysterious fact that you need to know!! 

There is an ECO valve on the left side towards the back of the heater. As per the expert’s reviews, this button acts as a reset button for the Girard models that can be pressed to reset the unit. 

For better visualization, take a look at the below pictures indicating the exact location of the Girard tankless water heater reset button.

Whenever there is an unsafe condition in the system, the switch gets tripped and shuts off the unit to prevent unwanted damage. The major reason that trips the button includes intermittent overheating, flame failure, erroneous heating issues, electrical disruptions, or any faulty wiring connections. 

As a result of this fact, the complete heating process becomes stalled and you won’t get the hot water as before.

Anyway, there is nothing to worry about! Through a quick resetting, the system will bring your heater unit into the default setting and start to heat the water again! 

Proceed to the below how-to section! 

How To Reset Girard Tankless Water Heater [2 Easy Methods To Follow!!]

Resetting your Girard tankless water heater is an easy and handy job. You can do it by following any of the below two methods. Here I’ve included both methods with the needed procedures. Here you go! 

Method #1: Through The Reset Button/ ECO Switch

Follow the below step-by-step procedures to reset the Girard tankless water heater through the ECO switch:

Step #1: Turn Off The Power Supply

First, you’ll have to shut off the power connection to your water heater. Turn off the power supply from the power switch. Just turn it off. Unplug the power cord from the wall socket. Or, you may also disconnect the electric supply from the circuit breaker. 

Locate the circuit breaker for your water heater and flip it to the “OFF” position. Before proceeding to the next step, make sure there is no electricity going through the unit.

Step #2: Shut Off The Hot Water Faucet

After disconnecting the power supply, it’s time to turn off the water flow to your heater. For instance, go to the hot water faucets for your water heater that is providing the water to the unit.

Turn the faucet clockwise and it will prevent water flowing to your heater when you’re working on it.

Step #3: Remove The Heater’s Front Panel

Now, to access the reset button, you need to remove the front panel of your water heater. It might be attached with a few screws. Just remove the screws and disconnect the front panel. When done, you will find the ON/Off power switch just at the front. Make sure it is turned off. 

Also, check out the fuse beside the heater power switch and ensure it is in well working condition. 

Step #4: Locate The Reset Button

After taking off the front panel, find the reset button from the inside. I’ve already mentioned the reset button location above with a clear image. 

Hope that you’ve located the reset button.

Step #5: Press & Hold The Reset Button

The reset button generally tends to pop in when the heater is going through a major malfunction. To reset, press the button to the inside firmly and it will pop out. 

That’s all you’ve done! Your tankless water heater is reset and the control panel will be set into the default settings. 

Step #6: Reassemble Your Tankless Water Heater

Once you have successfully reset your tankless water heater, it is time to reassemble the unit. Before that, turn the heater ON/Off switch to the “ON” position.

Then, place the front panel and screw it firmly. Turn the power switch back or plug the power cord to start the electric supply. 

Finally, turn on the hot water faucet and check whether your heater is running smoothly or not. If not, be sure there are some major issues with your water heater.

In such cases, you need to identify the root reason for that specific problem and fix those to get the heater back into normal operation. 

Here, our complete Girard tankless water heater troubleshooting guide may prove well in providing you with effective solutions for any heater problems.

Method #2: A Soft Reset  

Don’t worry if you can’t figure out the ECO or hi-limit switch on your Girard tankless water heater to reset your unit.

There is another effective method by which you can perform a soft reset on your water heater. To do a soft reset-

  • Turn the hot water faucets for your water heater to the off position. 
  • Wait for 10-15 minutes.
  • After that time, turn it back on. 

That’s done! The control panel of your water heater will be reset.

5 Major Issues That Would Trip The Girard Tankless Water Heater Reset Button

It’s not always proved well to just reset the heater to back all the heaters into normal situations. This is because there are several factors that most often lead to the reset button keeps tripping and stopping further water heating.

Thus, when the reset button trips off, it’s a good recommendation to figure out the actual reasons behind the issues. Here, I’ve listed a few major issues that would trip your tankless water heater randomly:

01. Faulty Thermostat

A failed thermostat is one of the major reasons why the reset button trips and the heater goes into Lockout mode. Either there would be a faulty wiring connection to the thermostat or the element is defective itself. 

Most of the time, there is no continuity through the thermostat for why it may stop working or be stuck. As the core function of the thermostat is regulating the water heater temperature, we can’t ignore a single malfunction of it.

How To Fix:

Inspect the thermostat and verify it has a good wiring connection to the heater. Then check the continuity of the element with a voltmeter. In case there is no continuity in the meter, be sure the thermostat has already failed and you need to replace it as soon as you can. 

02. Incorrect Temperature Setting

In most cases, the reset button trips when the thermostat is set to an inaccurate temperature setting. If you set the temperature too high or beyond the recommended level, it leads to the heater overheating. 

When this happens, the reset button automatically trips and turns off the heating water to protect you from getting scalded when you are using the hot water.

How To Fix:

It’s always better to ensure the proper temperature level in your thermostat. As per the Girard tankless water heater manual recommendation, you should not exceed the temperature of 115° (F).

03. Loose Or Faulty Wiring Connection

A loose wiring connection is one of the most common reasons why the reset button trips randomly. Basically, the bad wiring connection of the heater generates heat that affects the overall heating process of the unit. 

If so, it is certainly a critical safety hazard for you that needs immediate action to resolve.

How To Fix:

Inspect all the wiring connections of your water heater. Higher chances most of the ones are simply loosened. For instance, tighten it firmly.

In case you find any separation in the connectors or melted wires, don’t be late to contact a plumber to identify and fix the issues.

04. Bad Reset Button/ECO Switch

Along with all the above reasons, most of the time, a bad reset button is the culprit itself that is interrupting the heater from normal function. Basically, the reset button is one of the safety devices in the water heater that cuts off the energy to the unit in the case of high water temperatures.

But if the reset button has worn out, it will still cut off the power to the heater even after the temperature is normal.

How To Fix:

Inspect the reset button for any defection. If you suspect this device has failed, I recommend contacting a professional plumber to discuss the next step. 

05. Sediment Build-Up

If you have been using your RV tankless water heater for so long, building up the calcium and lime in the heater inside is quite obvious. The build-up of sediment throughout the system is one of the frequent causes of tripping the reset button continuously. 

During the heating process, the water heater may come into contact with hard water containing calcium and magnesium. After long use without proper maintenance, these naturally occurring minerals form into sediment particles that settle to the inside of the heater. 

When the sediment builds up, you will encounter several issues in the system, like overheating, temperature fluctuations, too hot water, rising energy bills, and so on.

How To Fix:

When sediment builds up, you will need to flush your water to remove the hard particles and restore the machine. Don’t get in trouble if you’re unaware of the right procedures about how you’ll flush your Girard tankless water heater.

This effective video will guide you through the easiest process to do so.

Why Will You Need To Reset Your Girard Tankless Water Heater

There are multiple reasons why the system demands a resetting to come back to normal operation. For your convenience here I’ve listed the major ones with all effective solutions beyond the resetting: 

01. No Hot Water

It is the most common phenomenon for users that the tankless water heater stops producing hot water suddenly. Whenever this happens, resetting the unit works like magic. 

You just need to turn off the power connection to your water heater, shut off the hot water faucet, and let the heater reset for about 10-15 minutes. Then turn the electric and water supply back on. 

In case the problem still persists, be sure there are several more responsive factors that you need to concentrate on. 

How To Fix:

Take a look at the below quick table highlighting all the probable reasons along with the instant solutions:

Probable Reasons Possible Solutions
Low-temperature setting Turn up the temperature on the thermostat. 
Interruption in the power supply# Make sure the heater power switch is ON.
# Replace the broken switch. 
# Reset the tripped circuit breaker. 
The gas valve isn’t fully openRemove the obstructions from the gas line
High water pressure # Adjust the water pressure from the flow regulator.
# If needed, replace the bad flow sensor.
Loose or worn-out wiringTighten the loose wiring or replace the worn-out ones. 
Blocked ventingInspect the exhaust venting for any obstructions. Clean it. 

02. Water Heater Keeps Turning Off

If your tankless water heater is failing to stay on, be sure there are some minor glitches in your system that continuously turn off while in operation. The problem can easily be resolved by restarting or resetting the system.

Unplug the heater from the power connection, remove the front cover, and access the ECO valve. Press the button and let the heater reset.

But if it fails to resolve the issue, you need to figure out the other reasons why your RV water heater shuts off too frequently.

How To Fix: 

Here, I’ve included all the probable responsive factors that are interrupting your tankless water heater to keep on:

Probable Reasons Possible Solutions 
Faulty power supply # Look for worn-out wiring and fix them.
# Reset the tripped circuit breaker.
# Replace the bad fuse. 
Low water flow# Increase the water pressure from the water control valve or pressure regulator. 
Insufficient water supply # Make sure all the exhaust venting of your heater is free of blockage.
# If needed, clean out the air inlet filter screen. 

03. Flame Failure

If your Girard tankless water heater isn’t igniting, or if there is no flame, there are several factors that would be responsible here. It mainly happens due to insufficient fuel supply. 

Either there is a leak in your propane system or the cylinder valve is not completely open. Above, the propane cylinder may be empty as well.

How To Fix:

Most of the time, resetting the unit will be enough to resolve the ignition failure in your RV tankless water heater. Do a soft reset in your system by turning off the hot water faucet and see whether your heater starts lighting again. 

If not, inspect the fuel supply system for your heater. Such as:

  • First off, check the propane cylinder tank and refill it if necessary.
  • Then make sure the valve is turned all the way open.
  • If all is okay, check for leaks in the tanks. You can easily identify it from the smell. Replace the leaked tank as soon as possible.

04. System Overload

While operating the water heater, you may notice a sudden reduction in water flow or volume from your shower faucet. It is most likely related to too many simultaneous hot water demands on your tankless heater. 

Basically, all RV tankless water heaters have a maximum flow rate capacity to provide hot water without any distractions. If you’re exceeding the recommended level of the maximum range, it will easily lead to system overloading. 

A system overload immediately shuts down the unit entirely or you will not get enough hot water or at times not at all. 

How To Fix:

  • First off, make sure there are not too many simultaneous demands that are being made on your RV tankless heater. Turn off some of the faucets.
  • Now reset the unit to factory or default settings.
  • If still the same problem persists, you may have to upgrade your system with a larger one to handle the volume of water you need. 

05. If There Is an Error Code Displayed

If the controller of the heater detects an unsafe condition in the system or the heater struggles with any issues, it triggers an error code corresponding to that specific problem. 

The most common Girard tankless water heater errors are E0, E1, E2, E3, E4, E5, E6, E7, E8, E9, En, and Fd. Each of the errors indicates different issues going through the system.

Anyway, whenever you encounter any of the error codes above, resetting the unit should be your first troubleshooting step. Most of the time, it will be enough to eliminate the code from the display. 

If not, you need to figure out the actual trouble points for that error by defining the error indication. For instance, our comprehensive Girard tankless water heater error codes will guide you with the best solutions. 

What Should I Do If the Resetting Process Doesn’t Work?

Well! After resetting your RV tankless water heater, it should come back to normal operation. In case, your heater’s problems haven’t been fixed yet, I recommend heading to the water heater specialists or contacting the Girard tankless water heater customer support for further discussion.
