Gas Water Heaters Troubleshooting Guide

Common Problems

Heater does not heat the water

The most fundamental and apparent complaint about a water heater is that it doesn’t work properly.The remedy to this problem is also the most fundamental.The following are possible causes of a malfunctioning Thermostat that prevents the water heater from generating hot water: It is a thermoelectric device known as a thermocouple that controls the temperature of water heaters.It is composed of a strip of two metals that acts as a thermostat.

  • It monitors the temperature of the flame from a pilot burner and cuts off the gas supply if the temperature is not high enough to light the pilot burner properly.
  • The presence of a malfunctioning thermocouple might result in the gas supply remaining shut off despite the fact that the heaters are in excellent condition.

Thermal sensor (thermocouple): The thermal sensor measures the temperature of the flame by directing the flame from the pilot burner onto the thermal sensor. Because of insufficient heat generated by the pilot burner, the thermostat may decide to keep the gas supply turned off.

If the pilot burner and thermostat are positioned in such a manner that the flame does not reach the thermostat at its maximum intensity, the assembly should be repositioned to correct the problem.Make certain that none of these components is clogged with silt or filth.The component that is at fault should be immediately replaced, if it is evident (for example, if the pilot burner does not ignite at all).In every other case, have a professional make his diagnosis.

  • Some heaters feature thermostat chambers that are completely sealed.
  • Don’t try to fix them yourself if you have one of these problems; instead, call a professional straight soon.

Heater works inefficiently

Problems in air combustion might arise as a result of incomplete burning operations and incorrect ventilation, which can impair the heater’s ability to work.The heating capacity of the heater is affected by various depositions in the heater, which are often caused by hard water or dust.The problem can be resolved by removing these encumbrances.If the heater still does not operate, it is possible that the pilot burner-thermocouple combination is faulty.

  • Check to be that the thermostat is set to the proper temperature, not a few degrees cooler than normal, before proceeding.
  • Check to see if the heater is capable of heating the amount of water you require.
  • It is possible that the water will be lukewarm if it is not properly fitted.
  • If this is the case, lower the water flow.
  • Check to see whether the gas supply is being obstructed in any way.
  • Gas water heaters require a constant supply of gas to operate at peak efficiency.
  • If the gas line is obstructed, the obstruction must be removed.
  • If there is even the slightest gas leakage, the gas line should be replaced immediately.
  • Check to see that the hot and cold water pipes do not come into contact at any point.
  • If this is the case, get a plumber to properly separate them.

Heater produces noise while heating

When the heater is in operation, the deposition and subsequent accumulation of insoluble scale in the tank might cause a popping sound to be heard. The problem should be resolved by just flushing the tank. If you notice any noise coming from your tankless heater, contact a professional right once.

Water from the heater stinks

Some water heaters heat the water by heating it with magnesium rods. Whenever these rods come into contact with bacteria present in the water, they generate hydrogen sulfide, which has the distinctive smell of rotten eggs about it. Chlorine bleach should be used to clean the tank (preferably flush afterwards). If the problem remains, try switching to zinc-plated rods.

Leakage from the heater tank

This is a grave problem, and the only way to resolve it is to completely replace the heater. Nonetheless, if the price is a deterrent, speak with a professional before making the choice to toss it; however, do not resort to a quick-fix solution.

Heater produces rust-colored water

It is possible for rusty-colored water to arise from corrosion caused by electrochemical processes occurring within the tank. Additionally, it may signal that the anode heating rod needs to be replaced in some instances. Changing the anode rods to zinc-plated ones will eliminate the rotten eggs smell, just as it did in the previous example.

Leakage from the pressure release valve

This condition can be caused by very hot water temperatures. It is possible to address the situation by lowering the thermostat. When this occurs, it can potentially signify a valve failure, in which case the valve must be replaced immediately.

Pilot light of the heater does not stay lit

Check to see that the pilot burner is adequately covered, since a gust of wind might cause it to go out completely.This problem is frequently caused by a malfunctioning thermocouple.It is possible that this problem will occur if the thermocouple in the thermostat assembly becomes displaced for whatever reason.It can be resolved by moving it to a different location or by replacing it.

  • WARNING: Do not leave a heater running while performing any repairs.
  • If at all feasible, turn off the gas supply.
  • As long as you are not disconnecting the gas line, you should not smell gas.
  • If you do smell gas, ensure sure the gas supply has been properly switched off.
  • If the odor remains, contact your local gas provider immediately.
  • Water heater parts should only be replaced or repaired under strict safety guidelines.
  • Before you begin to work on the heater, be sure that the pilot control valve has been turned off completely.
  • Disconnect the water supply to the heater and empty the heater of any remaining water.
  • Always look to the user handbook for troubleshooting instructions; more often than not, they will help you to resolve the issue.
  • If you believe the situation is too tough to solve, or that a certain action is too dangerous, you are almost certainly correct.
  • In such instances, it is best to consult with an expert.

In spite of the fact that gas water heaters are commonplace, mishaps involving gasoline may go tragically wrong in a split second.Early symptoms of an issue should not be ignored.Take precautions!

13 Common Water Heater Problems (Tricks to Fix)

  1. Modern water heaters are meant to last for a long period of time.
  2. The majority of them come with lengthy warranties, and you hope to be able to use them without issue for many years in the future.
  3. The combination of heat, water, and all of the many components that make them function, however, will always result in issues.
  1. Many problems with your heater are not life-threatening, and the key to repairing them is accurately diagnosing what is wrong with it.
  2. Here are our top 13 water heater problems – along with some advise on how to address them – to aid you in your diagnostic process.

Before you start

  1. There are many different types of water heaters available, including ones that run on gas and those that run on electricity.
  2. You should use extreme caution while working with an electric water heater since they are high-voltage equipment.
  3. Before you begin working on the heater’s electrical components, be certain that the power has been switched off – this involves turning off the breaker for your heater at the service panel – before you begin.
  1. Another precaution you should take is to use a voltage tester to check all of the wires before you start working with them.
  2. It is possible that failure to do so will result in significant harm or perhaps death.

1. No hot water

  1. In the event that you are experiencing no hot water, there are various probable causes, and you must work through each of them carefully in order to eliminate each one – and this will also depend on whether you have an electric or a gas-powered heater.
  2. In the most obvious case, an electric heater is unable to function because no electricity is being supplied to the heater.
  3. Begin by looking for tripped circuit breakers and resetting them if they are still in place.
  1. If this has happened, there is a simple solution: simply switch the computer off and on again.
  2. It is possible that you may need to replace the fuse if it has blown.
  3. The next step is to verify that the high-temperature cutoff is operational.
  • Open the panel and hit the red ″reset″ button to restart the system.
  • Check to see whether the water is now able to warm up.
  • You might also have a heating element or components that are malfunctioning, which is another option.
  • These should be tested and replaced if necessary.
  • If, after testing each of them, you are still unable to identify the source of your lack of hot water, it may be necessary to seek expert assistance.

Ensure that the gas valve is open if you are using a gas space heater or heater.If this is not the case, you may be experiencing difficulties with the pilot or the burner.Check out numbers 10, 11, and 12 below to discover how to deal with these problems.To learn more about how to troubleshoot an electric water heater in greater depth, please watch the video below:

2. Not enough hot water or water not hot enough

  1. When it comes to not having enough hot water, the explanation for this will vary depending on the sort of water heater you have.
  2. The problem with your heater if it has a tank might be as simple as the tank being insufficiently large for your purposes.
  3. If your tank is too small for the amount of people who will be showering, for example, you may run out of hot water before everyone has done their showering.
  1. If this is the case, you should consider investing in a new water heater that can accommodate your requirements.
  2. If your heater previously provided enough hot water for everyone but has abruptly stopped or is no longer capable of heating the water enough, the problem is most likely due to a faulty heating element.
  3. Examine them and replace them if required.
  • Another fast cure is to check the thermostat — you may just need to raise the temperature by a few degrees.
  • Also keep in mind that, during the winter, you may need to raise the thermostat setting since the groundwater you are heating comes at a lower temperature than in the summer.
  • If you have a tankless heater, you may be trying to run more fixtures than the unit’s power can handle.
  • Check the manufacturer’s specifications to see how many fixtures the unit can handle.
  • You might be experiencing difficulties because your heater is not strong enough for your needs.

Tankless heaters must also work harder in the winter, so if you are experiencing this issue during the colder months, it is possible that this is the cause of your problem.Upgrades to a more powerful unit may be necessary in your situation.

3. Water too hot

  1. That the thermostat has been set too high is almost probably the cause of the problem, but it is a simple problem to fix.
  2. Simply reduce the temperature on your thermostat and you should be set to go.
  3. The temperature pressure valve should be checked if this does not solve the problem; if it is malfunctioning, the heater will not shut off when it reaches the proper temperature.
  1. This is a potentially dangerous condition, and you will need to replace the valve as soon as you possibly can.

4. Water takes too long to heat

Among the possible causes of water taking a long time to heat are malfunctioning heating elements, silt buildup on the components, and a malfunctioning thermostat, among others. Ensure that you check each of these items in turn and replace them as necessary. If you have a gas-powered model, the problem might be due to the burner – see12 for more details.

5. Low water pressure

  1. Low water pressure is frequently caused by a lack of sufficient width in the pipes.
  2. Pipes in older homes are typically 12 inches in diameter, but pipes in newer homes are often 3 inches in diameter.
  3. If you live in an older house and are experiencing low water pressure, it is possible that the problem may not stem from the boiler at all.
  1. Instead, you may need to consider installing bigger pipes in your home to remedy the problem at hand.

6. Leaks

Leaks can occur as a consequence of loose connections, in which case you will need to tighten them using a wrench to prevent further damage. They can also emanate from valves, which can be changed if necessary. If the leak originates from the tank, the situation is more serious since the tank may be rusted. Corrosion will cause your tank to fail completely, and you will have to replace it.

7. Dirty water

If the color of your water begins to change to a nasty rust, you are most likely dealing with corrosion within your tank. The only way to fix this is to replace the tank entirely. However, it is possible that the problem is caused by a failing anode rod; thus, before replacing the tank, flush the tank and replace the anode rod to see whether this resolves the issue.

8. Smelly water

  1. If your water has a foul odor, it is possible that bacteria in your heater is to blame.
  2. This is especially prevalent if your water is obtained from a well, as it is in most cases.
  3. Flushing your tank may be beneficial, or you may try boiling the water to the highest temperature possible to eliminate all of the bacteria.
  1. It may be necessary to wipe it out with chlorine bleach if this does not work.
  2. The stench of rotten eggs in your water might be caused by a malfunctioning anode rod, in which case you should replace it immediately.

9. Tank makes noises

  1. It is possible for water heaters to create noise for a variety of reasons.
  2. As the water heats up, rumbling, popping, and banging sounds are produced by a build-up of scale in the tank and on the heating components.
  3. This is the most prevalent cause of the noises.
  1. If this is the case, emptying and descaling the tank may be necessary.
  2. To avoid this problem from arising in the first place, you should totally flush the tank out every few months to keep it clean.
  3. Depending on how serious the situation grows, you may be forced to replace the tank entirely.
  • Because of the usual expansion and contraction caused by heat, water heaters and pipes might create noise from time to time.
  • This is completely safe, but there isn’t much you can do to prevent the noise.

10. Pilot doesn’t light

  1. There are a variety of reasons why you may be experiencing problems with your pilot light.
  2. If it won’t light in the first place, it might be because the pilot light orifice or tube is blocked – or it could simply be that the pilot light needs to be replaced.
  3. Another possibility is that the thermocouple is defective or has come away from its socket.
  1. It is also possible that there is air in the gas line or that the gas valve is malfunctioning.

11. Pilot lights and then goes out

If the light comes on but then goes out, the reasons for this might be the same. It is possible that the thermocouple has to be replaced, that you have a defective gas valve, or that the vent has been clogged.

12. Burner goes out

This is most likely a similar issue to the one that was causing the pilot light to malfunction. It might be caused by a clogged orifice, a fault with the thermocouple, or a clogged orifice and vent.

13. No hot water for bathtub

  1. Even if you have no difficulty utilizing your shower or operating a dishwasher or washing machine, you may be experiencing difficulties getting hot water to run a bath.
  2. The issue might stem from your heater’s design.
  3. If you have a tankless heater, this is most likely the source of the problem.
  1. Tankless water heaters heat water as it runs through them, providing you with an endless supply of hot water on demand at all times.
  2. However, if the water passes through the system too rapidly, it will not have enough time to heat up properly.
  3. Showers and other uses do not necessitate such a big volume of water, thus the water will be heated to the temperature you anticipate it to be.
  • The water flow required to operate a bath, on the other hand, is significantly higher, and your tankless heater may simply not be able to keep up with it.
  • If this is the case, you will need to look into other options for heating your bath, since your tankless unit will not be able to provide you with the hot water that you require.

Identify the problem early

Often, the most essential thing you can do is recognize an issue as soon as possible and take efforts to resolve it as soon as possible. If you ignore the situation, it will only worsen and will almost certainly result in you having to pay more money in the future. And now that you’ve read this guide, you should have a solid sense of where to begin your search.

Gas Water Heater Not Working? Here’s a Troubleshooting Guide

You may use this troubleshooting guide to determine why your gas water heater isn’t working — or to know what to do if it ever does start working again.

How Does a Gas Water Heater Work?

  1. When a gas-fired water heater is used, it normally warms 40 to 60 gallons of water until the temperature reaches 120 to 140 degrees (we recommend 120 degrees).
  2. And it has been doing this for almost ten years, every single day.
  3. When it comes to a home workhorse as crucial as a refrigerator, anything can go wrong.
  1. That’s why it’s a good idea to become familiar with how they operate and how to troubleshoot them.
  2. When a hot water faucet is switched on, hot water is drawn from the tank of a gas water heater and discharged via the hot water outlet.
  3. It accomplishes this while cold water is being introduced into the tank through a dip tube.
  • A temperature decrease is detected and a valve is opened, sending gas to the burner, where it is lit by the pilot light or an electric spark, depending on the thermostat.
  • The flue is used to exhaust the heated air that has been released from the burner chamber (and its heat-retaining baffle).
  • After that, the air is expelled through the draft hood and vent.

What is A Gas Water Heater’s Recovery Capacity?

  1. The amount of gallons that can be heated from 50 degrees to 150 degrees (Fahrenheit) in one hour is referred to as the recovery capacity.
  2. This amount (as well as the tank’s capacity) is imprinted on a metal plate that is attached to the majority of gas water heaters.
  3. Hot water not being adequate is a typical complaint that is usually caused by a water heater that is too small.
  1. In other words, the problem is frequently caused by the fact that the demand for hot water exceeds the capacity of the tank to store it.

Gas Water Heater Maintenance

Here are four basic maintenance tasks that can help you improve the efficiency of your water heater. You should perform them on a regular basis as follows:

  1. Remove all debris from under and around the water heater to prevent dust from fouling the pilot and burner
  2. Drain the tank on a regular basis to ensure there is no sediment.
  3. Once a year, disassemble and thoroughly clean the vent and draft hoot.
  4. Once a year, inspect and test the temperature and pressure release valve (T&P Valve) on the water heater.

PRECAUTIONS: Before working on a gas water heater, be sure that the gas shutdown valve is turned off. If you need to make repairs to the control unit, pilot, burner, or gas supply lines (or if your tank is leaking or damaged), you should consider calling a reputable plumber to do the work. If the tank is leaking, be certain that the plumber is a trained emergency plumbing technician.
