You already know the many benefits of a tankless water heater. For instance, a tankless water heater is more reliable and occupies less space compared to the traditional tanked water heater. Such benefits are probably the reasons you invested in a tankless water heater in the first place. However, although a tankless water heater is much better than a tanked water heater, it can also develop problems that can negatively affect its efficacy and efficiency. Unfortunately, given the importance of the water heater in your Richardson, TX home, a water heater problem can cause serious inconveniences. For instance, it can force you and your family to take cold showers and perform other cleaning chores with ice-cold water. Therefore, if your water heater is broken, you need to ensure that it is immediately fixed by a professional tankless water heater repair expert. Below are some common reasons to call a water heater repair service to your house.

Mineral Buildup

The water in your house is not 100% pure. It can contain minerals such as magnesium and calcium. The harder the water coming to your home is, the more minerals it contains. With time, these minerals get deposited in your tankless water heater. Unfortunately, the mineral buildup in your unit can end up impairing its operation. For instance, it can block the valves and even render some components of your water heater defunct. To prevent such an eventuality, you need to ensure that your tankless water heater is serviced by a professional tankless water heater repair expert on a regular basis. The professional will ensure that your water heater is flushed and checked for any developing issues before the mineral deposits can start to cause any problems.

“No ignition” Message

Ignition problems are some of the most common issues that tankless water heater owners deal with. When there is an ignition problem, your water heater will display a message that reads “No ignition.” In most cases, ignition issues are caused by problems with gas supply. Therefore, when the “No ignition” message is displayed, you need to first confirm if you have run out of gas or if the valves are fully open. If you have enough gas in your propane tank and the water and gas valves seem okay, then the ignition kit could be faulty. In such a situation, you will need a professional tankless water heater repair to help you repair or replace the ignition kit, depending on what the underlying cause of the ignition problem is. Professional water heater repair experts have the necessary skills and tools to isolate the exact cause of the underlying ignition issue and advise you on the most efficient solution for it.

Flame Failure message

Flame failure is a common tankless water heater problem that usually occurs due to electrical issues or gas pressure issues. When you see your tankless water heater display the “flame failure” message, you should first confirm that you have not run out of gas before doing anything else. If your propane tank is full, then the problem might be a little more complicated for you. For instance, a flame failure could be caused by inadequate ventilation or even a faulty regulator. The issue can also occur if the gas line is too narrow. Whatever the underlying cause of the problem might be, you need to call a professional tankless water heater repair expert, such as Bluefrog Plumbing + Drain of North Dallas, to ensure that it is accurately diagnosed and quickly fixed to restore the supply of hot water to your house.

System Overload

Depending on the capacity of your water heater, having multiple hot water applications running simultaneously can overload it. For instance, the water heater might struggle to supply enough hot water when you have several showers running at the same time. Of course, you can solve this issue by cutting the demand for hot water at any given time. However, if your tankless water heater is getting overloaded on a frequent basis, it is imperative for you to talk to your tankless water heater repair expert about the need to upgrade or have an additional water heater.

Exhaust/Air Flow Blockage

If your tankless water heater is powered by propane, then it needs to be properly ventilated to ensure that it gets adequate oxygen to burn the fuel efficiently. Proper ventilation also ensures that the gasses produced by the combustion process are quickly released into the atmosphere to keep your water heater running smoothly. If your tankless water heater is not ventilated properly, it will display an error code informing you that the exhaust or air supply is blocked. In addition to making your water heater less efficient in how it burns the fuel, ventilation issues could also lead to a fire. Therefore, you need to call a professional tankless water heater repair expert as soon as you notice an error code warning you about poor ventilation. The professional will inspect the unit for any vent pipe blockages or deterioration and fix the issue accordingly.

The Bottom Line

Overall, it is apparent that although tankless water heaters come with a lot of benefits compared to tanked models, they are associated with some unique issues that can give homeowners some problems. Therefore, if you have invested in a tankless water heater, you need to be in touch with a professional tankless water heater repair expert you can always call when your water heater is not working as it should.
