Resetting EcoSmart Tankless Water Heaters (Fully Explained)

The most recent update was made on November 19th, 2021. Modern tankless water heaters have shown to be an extremely convenient addition to a wide range of home situations. It takes up less room and requires less upkeep. As a result, it is becoming increasingly popular as an alternative to traditional water heaters. EcoSmart tankless water heaters are the same as any other tankless or traditional tank water heater in terms of performance. They are nonetheless prone to malfunctions in spite of this.

This article discusses how to properly take care of your EcoSmart.

Several new tankless water heater types have been introduced recently, including those from EcoSmart in particular.

The sizes, uses, and energy efficiency of the options are all different.

EchoSmart Tankless Water Heater Reset Button

Some electric tankless water heaters feature a reset button on the side of the unit. In addition, it serves a very vital function. Malfunctions and possible electrical concerns might develop from time to time. As a safety measure, the reset button may trip and cause the machine to shut down as a feature. In such instance, the reset button effectively functions as an internal circuit breaker. It is a safety feature that keeps your water heater from sustaining additional harm. A significant electrical threat that may endanger you or your family is also prevented by this device.

Just make sure it isn’t the result of a lack of maintenance or careless handling of the unit before proceeding.

So, what is the best way to reset your EcoSmart?

If the device is not turning on, it is possible that a malfunction or a power surge occurred, which caused the fuse to blow. The problem can be resolved by changing the fuse. The unit can then be reset at that point.

Cleaning An EcoSmart Tankless Heating Unit

Cleaning an EcoSmart water heater is not a time-consuming endeavor. However, there are several processes involved. The cleaning process is divided into three parts, which are detailed below.

Preliminary Steps

Turning off the device is the first step. After that, turn off the tankless water heater’s circuit breakers by pressing the power button. Make certain you complete the next step. This assures that there is no electric current present that might electrocute you at any point in time. After that, turn off the water intake valve or shut off the main water supply. After that, turn on a hot water faucet in your home. This will completely drain any remaining hot water from the tankless device. Additionally, hot water will not scorch you after the hoses are disconnected. Close the outlet valve that is connected to the hot water output of the unit when that is done. As a precaution, loosen both the intake and output hoses from their respective valves. This will prevent any hot water from backflowing from the pipe when the hose is removed. They connect the unit’s intake and outlet water lines together
These hoses are flexible. After that, remove the front cover of your tankless water heater. This will need you to remove four screws, and then you will need to unscrew the wires that are linked to the heating element. The majority of tankless water heaters include more than one heating element. The heating components may be placed in a variety of locations. This is dependent on the individual EcoSmart model you have. On bigger devices, the heating components are located vertically on the top left side. Heating elements on smaller units should be laid horizontally on top
Then, unscrew the heating element in a counter-clockwise movement until it is completely removed. There will be some scale building on the copper tubing of the heating element, which you will notice.

Cleaning and Flushing

Remove the flow resistor from the water line leading out of the unit. Then thoroughly clean it inside and out to remove any mineral flakes or scale buildups. After that, immerse the heating element’s pipes in vinegar for a few minutes. You may also utilize a descaling method to help with the scaling. Allow the heating element to soak for a period of time until the scale accumulation is removed. This might take up to three hours or more. It is dependent on the quantity of buildup that has accumulated in the pipes. After soaking, some accumulation may still be present. It’s best to try to remove it with a towel that has been soaked in vinegar or a descaling solution. Make certain that the hexagon brass tops of the heating components remain completely dry throughout the process. They are equipped with technology that allows the electrical lines to rejoin. After that, make sure that the heating element is free of debris. Afterwards, reinstall it in the chambers from which it was removed. Reconnect the intake hose to the unit’s inlet water line using the hose clamps provided. Place a bucket beneath the outflow pipe so that it is completely submerged. This is where the water that runs out of the unit is collected. Following that, open the intake valve. Drain and check for leaks by allowing water to run through the device. It is possible that mineral flakes (in the bucket) will be expelled from the unit. Alternatively, let the water to continue to run until all flakes stuck inside the unit’s pipes have been flushed out.

Thorough Flushing

Units that are supplied with hard water will require extensive flushing. The same is true for tankless heaters whose owners do not do routine maintenance on them. In this case, just plain water will not be effective for the unit. It is preferable to use 3-4 gallons of undiluted white vinegar rather than diluted white vinegar. You may also utilize a descaling method to help with the scaling. This form of flushing will necessitate the use of a small submersible pump or any other circulating pump.

These hoses will be used to connect the unit’s intake and outflow to the appropriate connections.

The steps are as follows:

Close the intake valve once again, and then replace the unit’s cover for the time being. Water will not be able to splash onto the electrical components within the machine as a result of this. It is sufficient to secure it with two screws
After that, fill the bucket with all of the vinegar or descaling solution that you have. After that, install it immediately beneath the water heater unit, as shown. After that, disconnect the intake hose from the water input line of the device. It should be replaced with one of the laundry hoses. Check to be that it is properly attached to the inlet water line
Then connect the other end of this hose to the output of the submersible pump to complete the installation. Pour vinegar or a descaling solution into the bucket beneath the pump and submerge it. Connect the other end of the laundry hose to the water output line of the unit. Also submerge the other end of the hose in the bucket
Start the pump by pressing the button. Allow it to suck the vinegar or solution out of the bucket as it pleases. After that, pump it into and out of the unit’s system as needed. Do this for at least 30 minutes
You may notice some mineral flakes still coming out of the outlet beyond that time period. Allow it to run for a few more minutes in this situation. Make certain that the movement of fluid within the vehicle washes away all of the flakes and scale deposits

Assembling and Final Checks

Check to see that the unit is free of flakes and scale deposits before using it. After that, switch off the pump and disconnect the laundry hoses from both the water intake and output pipes of the machine. Make a new connection between the intake hose and the unit’s input water line. Reattach the flow resistor to the unit’s outlet by screwing it back in place. Afterwards, attach the outlet valve hose to the flow resistor located on the unit’s outlet. Check for leaks by re-opening the intake valve once again. Afterwards, turn on the exit valve as well. After that, take off the unit’s cover. Then, by inserting the wires into the heating components, you may complete the process. Place the cover back on top of the device. Also, make certain that the screw is securely fastened. After that, turn on the circuit breakers for the device. Then check to see whether the water is heating up via the taps. Finally, you may enjoy your clean, hot water once more.

Check to see sure the device is free of flakes and scale buildup. Afterwards, switch off the pump and disconnect the laundry hoses from both the water inlet and output lines of the machine. Reattach the intake hose to the unit’s input water line once again; and Reconnect the flow resistor to the unit’s outlet by screwing it back in place. Afterwards, attach the outlet valve hose to the flow resistor located on the unit’s outlet; and Examine for leaks by re-opening the intake valve. Afterwards, open both the inlet and exit valves.

Then, by putting the wires into the heating components, you may complete the connection.

Also, be certain that it is securely fastened.

Then, to see if the water is heating, check the faucets.

Filtration Maintenance

Maintaining your tankless unit’s filtration system is an important operation that keeps your tankless unit clean. Consult with your local municipal water provider if at all possible. Inquire about the water conditions in your neighborhood. You may even request that the water be tested. When you live in an area with hard water, this is extremely essential knowledge to have at your disposal. Whole-house water filtration systems can be used to keep filtration systems in good working order. Select the type of filtering you want.

You may find a variety of options at your local hardware or plumbing store.

It’s possible that you have hard water problems in your house.

As a result, the scale building on your tankless heater will be reduced significantly. More information about filtration may be found in the EcoSmartmanual, which can be found here.
