Like all other plumbing devices and appliances, the hot water heater can malfunction from time to time. A water heater can malfunction due to old age. With proper care and maintenance, conventional storage water heaters can last 10-15 years while tankless models can last up to 20 years. A water heater can also malfunction due to negligence and poor maintenance. You should always take good care of your hot water heater. Inspect the device regularly to ensure that it’s working properly. You should also hire a professional plumber to inspect the device more thoroughly once or twice a year. Low quality water heaters tend to break down very frequently. When shopping for a new water heater, consider the brand reputation and the warranty offered by the manufacturer. These two considerations will help you choose a high quality model. Whichever the cause, water heaters develop many different problems over time. The following are some of the most common water heater problems and we have also included viable solutions.

Temperature Control Problems

One of the most serious water problems is temperature control or setting problems. A water heater should have a perfectly working temperature control system. Most water heaters come with a default temperature setting of 140 degrees. But this temperature is a bit high and it can cause scalding if you use the water for showering or cleaning. The recommended temperature for a water heater is 120 degrees. At this temperature, no scalding will occur and it will also inhibit bacterial growth. But if your dishwasher does not preheat the water, you can always adjust to 140 degrees when cleaning the dishes and then back to 120 degrees. A serious problem occurs when the temperature control system is faulty. This means that you can set the temperature at 120 degrees and get water under or over that temperature. This can cause serious burn accidents in the house or supply you with cold water. If you notice such a problem in your water heater, call any professional plumber who provides Cincinnati water heater installation and repair services immediately.


Corrosion is one of the most common water heater problems at home. The hot water storage tank can corrode after repeated usage. But the water heater comes with an ingenious solution to prevent the tank from corroding. Water heaters have an anode rod that attracts all the minerals in the water thereby protecting the tank from corrosion. The anode rod corrodes instead of the tank. The anode rod should be inspected regularly and replaced when it’s worn out. If your water heater starts producing rusty water, then it means that the anode rod requires replacing or the tank is corroded.


Water heaters can start leaking at any time in any of their components. The connecting pipes that supply or remove water from the water heater can start leaking. The tank can also corrode, break, and start leaking. Inspect your water heater regularly to ensure that it’s not leaking. Call a professional plumber the moment you notice a leak.

Total Failure

A water heater can fail completely. It can stop working altogether. This can be caused by many different factors. It could have developed a short in the power supply system. It could also turn itself off automatically if there is a major problem in its settings or controls. If your water heater fails completely, call a professional plumber immediately.
