If your tankless water heater isn’t working as efficiently as it used to, it may be time for a reset. Follow these steps to reset your tankless water heater and get it back to peak performance.
Step 1: Disconnect the Tankless Water Heater
If you’re planning on inspecting or servicing your tankless water heater, it’s important to first disconnect it from electricity. This is a safety measure to ensure that you don’t get electrocuted while working on the unit. To do this, simply locate the cable that connects the unit to a power source and disconnect it.
Step 2: Find and Remove Cover Plate
Some models of tankless water heaters will have cover plates. Remove the cover plate with a Phillips or flathead screwdriver.
The cover plate sits on the front of the unit to protect the interior from the exterior. Once you locate the cover plate, you will see at least two screws holding it in place.
Use your screwdriver to remove the screws, and then carefully remove the cover plate. Beware of any sharp edges on the plate, and take care not to damage the unit as you remove the cover.
Step 3: Take Out the Insulation
When you remove the cover plate, you are likely to find insulation. Insulation acts as another barrier between the cover plate and the water heating unit. Remove the insulation from the tankless water heater. Inspect the insulation for any signs of moisture. Any signs of moisture can be indicative of a problem with the tankless water heater. If you find any moisture, it is best to contact a professional to have the problem assessed and repaired.
Step 4: Locate the Reset Button
If your tankless water heater isn’t working, the first thing you should check is the reset button. This button is usually located on the front or right side of the machine. If you can’t find it there, look at the back of the machine. If you still can’t find the reset button, call customer service.
Step 5: Change the Thermostat
Most tankless water heaters have a knob that changes the temperature of the thermostat. To change the thermostat, locate the knob and turn it clockwise. For the best results, turn the knob as far clockwise as it will go.
Step 6: Check for Power Outages in The Home
If your tankless water heater isn’t working, it could be indicative of a larger power issue in your home. Check for other power outages and see if any breaker switches are in the wrong position. You may just need to flip a switch to get your power back on. If the problem persists, you may have more serious electrical issues and should call a professional.
Is There a Reset Button on My Tankless Water Heater?
Most tankless water heaters have a reset button that can be used to restart the heating process if the unit stops working properly. The reset button is usually located on the front or right side of the unit. If your tankless water heater does not have a reset button, you may need to contact a professional for assistance.
What Are the Most Common Problems with Tankless Water Heaters?
If you’re looking for a way to save money and be more efficient, then a tankless water heater is a great option for you. These heaters work by heating water on-demand, so you’re not paying to heat water that you’re not using. Although they’re not very common, issues can arise with tankless water heaters if something isn’t working correctly. In this case, it’s best to consult with a professional to get the problem resolved.

What Happens When A Tankless Water Heater Fails?
If a gas tankless water heater fails to ignite, it could be because the gas jets have become dirty. In this case, it’s important to call a professional to clean the jets and ensure that the problem doesn’t persist. Ignition failure can also occur if there’s a problem with the pilot light or thermocouple. Again, in this situation, it’s best to consult a professional to diagnose and resolve the issue.
Why Does My Tankless Hot Water Heater Go Cold?
One of the most significant reasons why the tankless water heater suddenly turns cold during a shower is low water pressure. The flow of water within your device is lower than the activation flow rate required, resulting in the gas burner turning off or not igniting at all.
This can be a major inconvenience, especially if you are in the middle of a shower. There are a few things you can do to try and resolve this issue, such as increasing the water pressure within your home or checking for any blockages in the water heater itself.
What Trips the Reset Button on A Hot Water Heater?
There are several things that can trip the reset button on a hot water heater. Some of the most common reasons include power outages, malfunctioning thermostats, and pilot light issues. If you’re experiencing any of these problems, it’s best to call a professional to take a look at your hot water heater.
How Long Do You Hold the Reset Button on A Hot Water Heater?
To reset your hot water heater, press and hold the reset button for about 35 to 50 minutes. If your hot water heater has a pilot light, you may need to relight it after resetting the unit.
In conclusion, a tankless water heater troubleshooting guide will help you to determine where the issue is coming from. Tankless water heaters are efficient and easy to maintain but still can have issues that you need to take care of. You can always call a tankless water heater technician who will help you to fix or repair your water heater.
