8 Possible Reasons Electric Water Heater no Hot  Water (2021)

Expect hot water to come out when you turn on the sink or shower. Taking a shower is unpleasant in some respects, as there is no hot water and it has to be cold. Apart from the impact of frozen water, you can also worry about the energy efficiency of the water heater and whether there is a natural gas leak. Before focusing on the worst scenario, you can be confident that there are many reasons why your home does not have hot water. To start troubleshooting, make sure your home has a gas or electric water heater. Here are some common reasons for water problems and how to fix them.

  • Tank Leak 

There must be water in the tank for the water heater to do its job. If there is no hot water, the tank may be leaking. Empty tanks are a serious problem and are not energy efficient at all. Check the connection between the device and its valves and pipes. If you are sure, check the tank compartment. If there is water in the compartment, it is very likely that the device will need to be replaced.Tank leak

  • Gas leak 

Leakage of natural gas from the water heater is troublesome and dangerous. If you suspect a gas leak, please contact the gas company as soon as possible. The technician at the gas company is an expert, but his goal is not to repair the water heater. The next step depends on the evaluation of the device. In the event of a gas leak, the gas company will work on a local solution. If there are no gas leaks, continue troubleshooting.

Signs and symptoms of a gas leak
  • Electric water heater failure

When it comes to water heaters, energy efficiency is important. Both electric and gas water heaters can keep you awake in the house without hot water. But do you know the difference between gas and electric water heaters? The electric version is of course based on electricity. If you don’t have hot water in your house, turn off the heating first. Then reset the breaker. If the breaker trips, your home will get hot water again in about an hour. Circuit breakers that keep tripping are a bad sign. Therefore, press the reset button. If the problem persists, please contact a qualified electrician.

  • Defective gas valve 

If you have a gas water heater and no hot water, you need to check the power line of the appliance. If there are no leaks, look at the gas valve. It must be safe and in the right place. Then double-check that the gas is on. When the gas valve is ready, check the indicator light. The pilot may need to turn it back on several times. It has to stay. If this is not the case, the gas supply is cut off and the gas mains may be the cause.

If none of these steps provide hot water within an hour, it may be time to invest in a new energy-efficient water heater. Be sure to call an expert.

Keep in mind that there are additional costs to consider when replacing a water heater, and most homeowners choose either a traditional water heater or a tankless water heater.Defective gas valve

  • Defective thermostat

The thermostat must be set between 122 and 140 degrees Fahrenheit for the water heater to produce hot water and be more energy-efficient. If you don’t have hot water, lack power, or are too hot, check the thermostat at the top. If the thermostat is defective, it will need to be replaced. Lack of regular maintenance can cause problems even if the thermostat is functioning due to sediment buildup. To solve this problem, wash the water heater.

If the tank is too small, the household will be less energy efficient and will soon run out of hot water. Perhaps the device did the job only when you and your spouse. But as your family grew, so did the demand for hot water and more hot showers. This means it’s time for a larger hot water tank. Please note that when updating, electric water heaters take longer to heat than gas water heaters.

  • Weather

The outside air temperature determines how fast the water can be heated. Even in areas such as the southwest, the energy efficiency and performance of hot water tanks can be compromised in winter. Living in areas exposed to cold splashes can affect the system and cause water problems. You may need to get out of the cold and isolate your device.

  • Recommended tools and materials

If you are looking for energy efficiency at home, you may want to replace or repair your water heater yourself. It is always advisable to leave the work to a qualified electrician. However, if you want to try out DIY projects but have some experience, you will need tools such as:

  • Driver
  • Key
  • Electricity and plumbing tape
  • Safety goggles
  • Welding torch
  • Pipe cutter

Any other tools will depend on the type of heater you have

Water Heater no Hot  Water in the House?

On-demand hot water is natural for us. One of the worst things homeowners can experience is the lack of hot water in their homes. There are many cases where hot water does not work because the water heater wears out or does not work.

No hot water electric water heater

There are several reasons why electric water heaters don’t work at all. Review the following areas to begin troubleshooting.

Defects in heating elements

Heating elements can fail and are actually one of the most common problems with electric water heaters (if any). You’ll have to replace the elements of the water heater, but fortunately, it’s pretty easy.

Faulty thermostat

The upper thermostat of the electric water heater actually controls both the upper and lower heating elements. This leads to a terrifying situation where hot water does not work. The lower thermostat controls only the lower heating element. So if it doesn’t work (but the thermostat at the top works), the hot water isn’t heated enough. Solution: Replace Thermostat

The circuit breaker has fallen

Check the breaker box to see if the water heater is working. Water heaters (like other large devices) require their own electrical circuits. The water heater switch should be easy to see when triggered. It does not match the other switches in the box.

To reset, toggle the switch to the “off” position and then to the “on” position. If you click again, you will need to contact your electrician to diagnose the problem.

Other causes of water heater, no hot water

  • Accidental grounding

Look for short-circuited foreign objects in the electrical connections.

  • Reset button triggered

Repetitive interventions can be a sign of reset button failure. First, try resetting your water heater. If that doesn’t work, you’ll need to replace the component.

  • Short thread 

Frayed or scratched cables can cause a direct short circuit. Replace the failed cable immediately to avoid the possibility of fire.

  • Water leak

If you don’t have hot water, it’s not your typical slow drip leak, so it’s pretty clear if a leak is a problem. If the tightening does not work, you may be able to tighten and replace the leaking connection. Many leaking water heaters are easy to repair, but leaking tanks mean that the water heater needs to be replaced.

  • Small fuse or breaker

Replace the defective device with a device designed for higher amperage. This probably doesn’t happen anywhere, but if you just replaced your water heater with a new model, this could be the cause.

  • Weak breaker

This is especially true for the elderly. However, circuit breakers can fail over time and must be replaced. Replace the switch.

No hot water-gas water heater

Gas units have different problems than electrical units, but usually, both types can be repaired. Special care should be taken when handling natural gas. If you repair it yourself, do it only if you are 100% sure. Otherwise, please refer to the form above for at least one free quote from a local plumbing expert.

If your water heater does not hot water in your house, check the following:

  • No gas supply

Something is blocking the gas from reaching the pilot and burner. The gas supply may have been accidentally interrupted. Make sure the gas is on and the gas valve is not in the closed position. In that case, open the valve and follow the steps to reignite the pilot.

  • The light is off

If gas is flowing even though it is off, check the following points.

  • Thermocouple

The tip of the thermocouple must be in the flame of the pilot flame and firmly connected to the gas line. If checked, check the thermocouple for clogging and replace the thermocouple if necessary.

  • Line air

Check the gas flow and turn on the pilot light several times to push the air out of the line.

  • Pilot port blocked

This component can be removed and cleaned to improve the functionality of the water heater.

Power line blockage, twist, or defect

Holes in the gas line can cause intermittent heating. Replace defective cables immediately.

  • Defective gas control valve

This component can prevent the gas from reaching the igniter or burner. The gas valve cannot be repaired, but it can be replaced cheaply.

  • The burner is dirty or clogged

Soot can build up on the main burner, preventing proper heating and completely blocking the burner’s ignition. Remove and clean the parts.

  • ventilation

Chimneys can be blocked by external events such as storms and rodents. Cleaning the fireplace is not difficult, but it can be a hassle. Excessive or unusual winds can knock down the funnel and annihilate the pilot.

The water is not hot enough

If the drive continues to function with intermittent results, the system components may fail. Once you have verified that your water heater is large enough for the application you need, it is most likely that one of the following suggestions is the component to be repaired.

  • Check the thermostat

If the temperature control is set correctly, the thermostat itself may need to be replaced. As mentioned earlier, when the heat isn’t hot enough, it’s often due to a bad thermostat.

  • Check the burner

Sediment accumulates Gas water heater burners can prevent the water from heating properly. In rare cases, the burner group itself can fail over time. A do-it-yourself replacement is possible, but it is recommended that a specialist handle it.

  • Examine the dip tube

Failure of this component is not common, but it does occur occasionally. It is unlikely that you have 20 million water heaters made of fragile polypropylene tubing between 1993 and 1996, but even recent ones have no guarantee against failure. In the event of a failure, the water heater immersion tube will need to be replaced.

  • Wiring is loose

Loose connections to electric water pipes can cause the unit to malfunction. Power off the device and make sure all connections are safe and free of corrosion. This problem is very rare.
