The tankless water heater is a great choice for your home. It is convenient, energy efficient, and can save you dollars on your energy bills each month. However, there are times when it can malfunction and need repair.

That’s why The Clog Dawg Plumbing & Hydrojetting Inc is here. In this article, we’ll walk you through how to check for some normal tankless water heater issues and how to fix them before calling for professional help.
What Are The Tankless Water Heater’s Pros And Cons?
If you’ve ever had a water heater, you know what a pain it can be to wait for your hot water to heat up—especially if you’re in the shower and have left the faucet on. With a tankless water heater, you no longer have to worry about this problem.
However, like with any other product on the market, there are some pros and cons to consider before making your decision.
Here’s a chart that provides a side-by-side overview of the pros and cons of tankless water heaters:
| Pros | Cons |
| Energy efficient | Higher upfront cost |
| Continuous hot water supply | Limited flow rate for simultaneous use |
| Space-saving design | Initial lag time for hot water delivery |
| Longer lifespan | May require an upgraded electrical or gas supply |
| Reduced risk of water damage from leaks | Maintenance and descaling requirements |
What Causes Tankless Water Heaters To Go Bad?
If you’ve ever had a tankless water heater go bad, you know it’s not a fun experience. And if you’re trying to figure out what caused your tankless water heater to fail, it can be even more frustrating.
Several factors can contribute to the deterioration or failure of a tankless water heater. Here are some common causes:
Sediment buildup
One of the main reasons why tankless water heaters stop working is because of sediment buildup. You may have heard of this before: sediment is tiny particles that clog up your pipes, making them less effective at heating water.
Hard water
Hard water creates scale inside the tankless water heater, which causes it not to work properly. Hard water is caused by minerals in your tap water that build up over time and make it difficult for your tankless water heater to function properly.
Faulty wiring or a faulty thermostat
If the wiring in your tankless water heater is faulty, or if the thermostat is faulty and cannot send signals to the unit’s heating elements, then your heater will not work correctly and may even break down entirely.
Lack of maintenance
If you don’t keep up with the maintenance of tankless water heaters, it can lead to problems. It’s important to keep the system clean and free of sediment so that it continues to work at its best. You should also be mindful of how much water is going into the tankless heater so that it doesn’t overload or run dry.
Overloading the system
If you are using too much water in a short period of time, this can cause your tankless heater to stop working properly. If you have a lot of people living in your home or if many guests are visiting at once, then it’s best not to utilize more than one faucet at a time because this will overload the system and cause problems with heating up water quickly enough for everyone who needs it!
Faulty parts inside
Sometimes there are parts inside the system itself that break down over time due to regular wear and tear from being used frequently every day over long periods (or even shorter periods!). These components might need replacing if they stop working or no longer function properly due to damage done by repeated use over time.
Improper installation or setup
A tankless water heater works by heating up a coil of copper tubing that runs via your house. If there’s any kind of kink or kink in the line anywhere along its path, it’ll cause problems—not just for heating up your water but also for heating up your wallet as you replace parts over and over again!
Incorrect voltage supply
Tankless water heaters use electricity (duh), so if there isn’t enough juice coming into the house from the electrical company, your heater won’t work either!
Pro Tips Before Calling the Experts for Tankless Water Heater Repair
A tankless water heater is an amazing piece of equipment that can reduce your energy costs by up to 70% and your water heating bill by up to 20%. However, if you don’t use it properly or if you don’t maintain it, things might not go as smoothly.
That’s why we’ve put together this list of common tankless water heater problems and how you can fix them before calling a professional plumber for Tankless Water Heater Repair & Installation in North Atlanta.
No Hot Water:
- Check the power supply: Ensure that the unit is receiving power and that there are no tripped circuit breakers or blown fuses.
- Inspect the gas supply (for gas-powered units): Ensure the gas valve is loose and that there is an adequate supply of gas.
- Check for error codes: Tankless water heaters often have error codes that can help diagnose specific issues. Refer to the manufacturer’s manual to identify and troubleshoot the specific error code.
- Flush the system: Sediment or scale buildup can affect water flow and heating. Flushing the system may help remove any blockages.
Insufficient Hot Water:
- Check the flow rate: Tankless water heaters have a maximum flow rate they can handle. Ensure you do not exceed the heater’s capacity by running too many hot water appliances simultaneously.
- Clean or descale the unit: Mineral deposits can accumulate over time, reducing heat transfer efficiency. Cleaning or descaling the heat exchanger may improve performance.
- Adjust temperature settings: Check if the temperature settings on the unit are appropriately adjusted. Increasing the temperature setting may help if the water is not hot enough.
Intermittent Hot Water:
- Check for error codes: Like the “No hot water” issue, error codes can provide insight into the specific problem. Refer to the manufacturer’s manual for troubleshooting instructions.
- Clean or replace the air intake or exhaust vents: Blocked or restricted vents can cause the unit to shut off or operate improperly. Ensure that the vents are clean and free from obstructions.
- Inspect the gas supply: If the unit is gas-powered, ensure that there is a proper and consistent gas supply.
Error Codes Or Malfunctions:
- Refer to the manual: Error codes are typically specific to the manufacturer and model. Consult the manual to identify the meaning of the error code and follow the recommended troubleshooting steps.
- Reset the unit: Sometimes, a simple reset can resolve minor malfunctions. Turn off the power to the unit, wait a few minutes, and then turn it back on.
Regular Tankless Water Heater Maintenance is the Key
It’s time to take your water heater seriously.
Your water heater is a lot like a car: it’s an important part of the household that you don’t think about until it stops working. And when it does, you’re going to be really annoyed.
That’s why we’re here—to help you avoid that situation. We’ll give you some helpful tips for regularly maintaining a tankless water heater and will walk you through the many benefits of regular tankless water heater maintenance.
Here are some key maintenance tasks that should be performed on a regular basis for tankless water heater maintenance:
- Look for leaks and cracks in the casing.
- Make sure it’s not overheating or underperforming.
- Consider replacing your tank if you’ve had it for 10 years or more.
- Check your tankless water heater’s temperature gauge regularly. If it shows that the water is too hot, there may be something wrong with the system, and you should contact a professional immediately.
- Make sure that any filters have not become clogged and are cleaned regularly. This will help ensure that the flow of water through your tankless unit is not restricted in any way and that all parts of the system work properly together as one piece.
- Be sure to immediately replace any corroded or damaged parts so they do not cause further damage or create new problems for you down the line!
- Be sure to follow the manufacturer’s instructions for cleaning and maintenance.
- Check the venting system at least once per year for clogs or leaks.
- Check the electrical connections at least once yearly for corrosion or lost connections.
- Turn it down a notch. When you first turn on your tankless water heater, don’t use it at full capacity right away. Once the unit has had a chance to warm up and get comfortable in its new home, then go ahead and start using it for everything from showering to washing dishes.
- Keep the gas supply line away from other appliances and vents to avoid carbon monoxide leaks.
- Inspect the electrical wiring to ensure it is safe and up to code. You can also check that all ground wires are intact and securely attached to the base of your tankless water heater.
- Make sure you’re using the right size tankless water heater for your home’s needs—if you have too many occupants or too much laundry, you’ll need to upgrade!
- Stay on top of the maintenance schedule to keep your tankless water heater working at maximum efficiency.
Have you ever wondered what the benefits of maintaining your tankless water heater are? Now, If you own a tankless water heater, you know that it’s not always the easiest thing to keep up with.
