The cold season is here and you are all set to have a warm and fresh bath. You have a water heater that helps you have that privilege. But what if your hot water turns lukewarm, or cold or it runs out before you’re done with your shower, who is to blame?

Definitely, it’s the water heater.

Whenever such kinds of incident occur the first thing that you must do is to check the water heater so you can find out the actual problem. If the problem is the with the setting of the heater, then opt for resetting it.

So, to help you out, this article will highlight how to reset the water heater so you can enjoy warm water as anticipated.

If you have experience working with electricity, only then you can follow these steps. Or else we would advise you to contact a professional.

Resetting Water Heater in 2019

Step 1: Disconnect the Water Heater

Have a visual inspection of the heater conducted to check out if the reservoir is leaking or the TP valve is releasing water. The TP valve basically stands for temperature and pressure relief valve. The TP valve should be placed on or close to the top of the water tank. On the basis of the location of the leaks, water can be found on the top, bottom or sides of the heating device. You can also find water on the floor or walls around it.

If water is present, then you have the turn off the breaker from the electric panel prior to approaching the water heater. Once you turn that off, you need to turn the water off via closing the valve above or near it. Note that you have to close it clockwise. If the area is dry, you also have to turn off the breaker so you can examine the cause of the issue.

Step 2: Take Out the Cover Plates

Take out the cover plates from the face of the water heater. You will basically find two of them. The energy cut-off or ECO which is the high limit switch is a safety device that helps cut off all the power connected to the upper and lower elements and their thermostats when overheating occurs. It should be located below the top cover and affixed against the reservoir above the upper thermostat directly.

In general, the energy cut-off trips when the water temperature in the reservoir gets in the range between 150 to 180 degree Fahrenheit. But that depends on the sensitivity of the heater. You cannot reset such safety device until the temperature of the water is cooler than that of the temperature in which the energy cut-off got tripped. This ECO switch basically differs the exact temperature drop that is required.

Step 3: Take Out the Insulation Pad

You will find a foam insulation pad right there inside the water heater. It helps conceal the button you which you need to access to reset the unit. You will have to take the pad out with your hands and keep it aside. There you will find a reset button which is red in color on the ECO. If you find any moisture surrounding the reset button or on the pad, chances are that the element gasket is leaking. So at first, you will have to fix the leaking. Then press the button to reset the water heater. You will hear a clicking sound if the heater has cooled down adequately and that the energy cut-off is working appropriately.

If the button does not click immediately, then keep your finger pressed against the button until you get the click sound.

What if you don’t hear the click?

If you do not get to hear the click after you press the reset button, then you will have to examine all the wires of the heater for loose wire nuts. If you think the wiring is fine, then perhaps you need to replace the controller.

Different heaters work in different ways. While some of them click immediately, some take five seconds to click. If you still don’t hear the sound, then reassemble the heater anyway as it will still restore the hot water.

If the Switch doesn’t Reset

Step 1: Thermostat Replacement

Replace the thermostat if the switch of energy cut off device fails to reset or if it trips frequently. Do the replacement task only if you have experienced, or else you will have to call an expert or a plumber to analyze and repair the issue.

Step 2: Interior Parts Inspection

Investigate the interior part of the heater for the sign of burn or overheating. If you are someone professional DIYer, then you can change the burnt out thermostats or heating elements. Besides, you can also change the anode rod if required. But all of these are dependent on your comfort zone and your experience. When the anode rod gets corroded, it affects the functionality of the water heater This kind of rods have been engineered to be a sacrificial part of the water heater so you can sacrifice it and get a new one when the existing one deteriorates.

Reassembling the Heater:

Step one: Put back the Insulation Pad

You will need to put the insulation pad back to the heater. Take the pad which you had taken out earlier.

Step 2: Screw Back

Then you will need to put the door on the control panel back in place and the screw it to fix it.

Step 3: Turn the Power On

Then have the cable plugged in for restoring the power. You can also flip the necessary switch for that. Wait for few hours, your water should be heated by then to run properly.

Wrap Up!

So, this is how you reset the water heater. You have to be very patient while performing all the steps. However, If you have no idea regarding the way to switch off and reset the heater, then it’s better you call an expert to do that for you. It would be very risky to mess around with a water heater if it’s turned on.

How to Test Water Heater Element 2019!

The cold season might trigger you to use water heater mostly. But just like all the other electric devices, a water heater can also stop working properly. The most mainstream situation can be the time when the heater produced less hot water or no hot water. And when that happens, the elements or their thermostats may be at fault. At this point, the first thing you should do is to check the functioning of the elements yourself. you can perform a test if you want to find out the culprit.

So, in the write, you will get to know how to test the water heater element properly. If you follow the steps just like the way mentioned here, you can complete the testing mission successfully.

How do Water Heater Elements Work?

Electric water heaters mostly come with two elements. And it’s possible that both or either of them could go off. Moreover, you will also find a thermostat for each of the elements.

If something goes wrong with the thermostats, then the elements will not be able to heat up. In this case, all you should do is: get a few testers and a couple of precautions. Then you’re all geared up!

Most of the time, it is seen that the upper element of heating and its thermostat control the lower one and its thermostat. If water heater no longer produces hot water, then either upper element or its thermostat could be the actual culprit. But if the device starts warming up water but it’s not as much hot as it should, then suspect the lower element or its thermostat.

But no worries! There are a few tests that you can do so you can understand the actual issue with the heater.

Things You’ll Need!

  • Noncontact voltage detector
  • Multi-meter
  • Voltage tester
  • Screwdriver
  • Safety goggles
  • Gloves

Methods of Testing

If you see your water heater that is tripping the circuit breaker continually, then perhaps it could mean that the element got grounded and might end up creating an electric short. At this point, you will need a multi-meter so you can find out how the elements went damaged.

Before that, you should turn off the breaker inside the main electric panel that provides power to the heating device. Majority of the water heaters use a circuit breaker that comes with 30-amp double-pole.

Try to find the panels that are fixed with the screws to each of the water heater’s sides. Relying on what the size your water heater is, the device will either have one or two panels. Take out the screws so you can release them from the panels.

Also, take out the insulation that was exposed whole taking out the panels. The type of insulation will depend on the age of the heating device, it could be either closed-cell extruded polystyrene foam or fiberglass.

Has it pulled the plastic safety cover from the face of the element? The cover basically snaps on and off the elements and the thermostats.

Then, use a non-contact voltage detector and hold it just next to the wires that are connected to the face of the element. And then hold it near to each wire that is connected to the thermostat. You will find the voltage detector emitting an audible alarm and flashing light if there is electricity present in the water heater.

Loosen the screws of two elements and take out the wires from the screws below. Keep a note of the wattage of an element that is written on the sides of the element face.

Rotate the dial on the multimeter to Rx1k which means ‘resistance times 1,000 ohms. Touch any of the screws of element face with one of the probes of the multimeter. Place the other probe on the other screw. If the element has 3,500 wattages, then it should register 1516 ohms, if it has 4,500 wattages, then it should register 12-13 ohms, and if it has 5,500 wattages, then it should register 10-11 ohms. Switch the element if it doesn’t register on the multimeter.

Leave any of the probes touching one of the screws on the face of the element. Then leave the other probe touching a metal part of the heating device. If the needle of the multi-meter happens to move, then the heater element is grounded. It means you must replace the element.

It is also important to ensure that you test both the screws on the element face.

Touch each of the screws with one of the probes of a multimeter. Place the other probe against the base of the metal that is connected to the element where it enters the heating device. If the needle on the face of the multi-meter moves, then it means that the element is damaged and you must replace it.

Have it attached the wires back to the face of the element. Clip the plastic cover on the element and the thermostat. After that re-install the insulation and fix the panels to the sides of the water reservoir. Then, turn on the breaker to the heating device.

Safety Tips

Make sure before you step into the testing water heater, you wear safety gears such as goggles and gloves. These gears will keep you protected from any accident or risk that can occur during the inspection. Also, check if you have unplugged the main power of the heater and turned it off. You should also drain the water from the tank as well before conducting a test of the water heater element.

Wrap Up!

Testing water heater element can be a little time consuming, but it needs nothing but some testers, gears and your determination. If you get dependent on someone professional, then it is expected that they will end up charging you up with a lot of fees. But, if you can get the job done on your own, then it will not only be convenient to fix a damaged water element but also save you up a lot of your money. Hopefully, now you will be able to test the water heater element in a proper way without the need of any professional.

How to Maintain Water Heater 2019!

A water heater is likely to last around 7 to 12 years depending on the proper maintenance. So, if you want the heater to work properly then maintenance is definitely required. Be it regularly, week, monthly or annually, it is essential that you examine every part of the heater.

However, we would never advise you to maintain the water heater if you don’t have any experience working with electricity or plumbing.  So, it’s better to go for it only if you think yourself someone experienced.

Coming back to the main point, the water heater requires some love and care since it will boost up the performance of the unit.

And if don’t know how to maintain a water heater, then this guide will help you out.

Services the Water Heater

If you plan to go through regular servicing, you won’t be needing any expert to do the task for you. With the help of a bucket and a screwdriver, you can conduct the servicing task of the water heater all by yourself. Prior to going for it, make sure you turn the power off for safety.

Turn the circuit breaker for the water heater in the breaker box.
Turn the pilot knob (that is situated on the thermostat or valve of the water heater) to the off point.

TPR Valve Test

Turn the power and the water supply valve off. Have a bucket placed below the pipe that is linked to the TPR (temperature pressure release) valve on the side or top of the water reservoir. The TPR valve opens only when the pressure of the tank is higher. Lift the tab of the valve to drain the tank. If the water keeps on flowing, then drain it halfway. With a pipe wrench, unscrew the old valve and set up the new one. It’s because frequent replacement of TPR valve will help the water heater last longer.

Anode Rod Analysis

Place a hose to the drain cock of the reservoir and let a few amounts of water gallon drain. Now, put a 1 1/16 inches socket on the top of the anode rod’s hex head onto the heater.

Then unscrew the rod. If it is coated with calcium or is less than 0.5 inches thick, then you have to get a new one and wrap the threads with a seal tape.

Then, place the new rod back to the reservoir and after that tighten it firmly.

Sediment Subtraction

Drain the water into the bucket from the tank and start gearing up to wash out all the sediments that have built up on the bottom of the tank. Removing the sediment will prevent rust and also enhance the energy efficiency of the heater.

The best will be only if you do a complete flush of the unit, although it will require the shutting down of the water heater.

However, you can also opt for a mini-flush since that will work well enough for washing out the sediments. It will take a fraction of your time and you can do it while running the water heater.

Have a bucket placed below the drain valve that is there close to the bottom of the tank.

Dial the valve counterclockwise so you can drain about 2-gallon of water into the bucket. While some drain valves comprise of a short stem with a slot to use a screwdriver, some of them come with a handle. However, after you finish doing the mini flush, dial the valve clockwise to close it back.

You have to be very careful while doing the task since the water will be scalding hot and it can burn you up.

Temperature Adjustment Tasks

Unscrew the cover after you notice the temperature dial on the water tank’s side. Water heaters are basically preset to the temperature of 130 to 140 degree Fahrenheit. If not, then it is better to adjust the temperature by dialing to 120-degree Fahrenheit using a screwdriver. You can expect to save around 5% of the energy bill for lowering every 10-degree temperature. If you are planning to be away from home for quite often, switch off the water heater and tune the thermostat down to its lowest setting.

However, you might also require to take out a small metal panel that covers the thermostat, if you want to lower the temperature.

For this, turn off the breaker at the breaker box and switch off the power of the heater.

Then, you have to take the access panel of the thermostat and set the temperature to your preferred setting.

After that, have the thermostat cover replaced and switch on the power again at the breaker box.

Mission – Pipe insulation

Make a purchase of a couple of self-sticking foam pipe insulation that comes in 3/8 inches thick and matches the diameter of the pipe. Slide the foam pad on the pipes as far as your hands can reach. Squeeze the insulation closed after peeling the tape. If the pipe is 6-inch long or lesser from the flue, cover it using the fiberglass pipe wrap. Make sure the wrap is 1-inch thick.

If you insulate the cold water pipe, it will help prevent the condensation during summertime.

Mission – Heater insulation

Cut the insulation blanket so it can fit the Temperature pressure release valve, the pipes and the temperature control that has been stuck out of the tank. Seal the cuts using a tape after wrapping the side of the tank. Don’t cover the top of a gas or propane liquid heaters. But as for the electric ones, cap the heater using insulation that’ll come in an oversized circle. After that, wrap the edges with the tape securely to the tank’s side.


Maintaining the water heater is definitely not one’s cup of tea. But if you want to enjoy the privilege of warm water, then you have to show enough care.

As we have underlined every part and area of the water heater that you can perform maintenance on, it will be easier for you to do all the task.

But before that, don’t forget to judge your level of expertise!
