Having a tankless water heater installed in your home is a great way to ensure that you have consistent hot water when you need it. However, like other hot water heaters, tankless hot water heaters aren't immune to problems and needing repairs. Here are a few signs that your tankless hot water heater may need repair.

Water Isn't Getting As Hot As You Expect It To

While most tankless hot water heaters will last for a couple of decades under normal use and proper maintenance, excessive use can cause your tankless water heater to fail prematurely. Usually, this failure starts progressively, beginning with reduced temperatures in your hot water. You should have the water heater examined by a repair technician right away when this starts to occur.

It's important to note that imminent failure isn't the only reason for reduced hot water temperatures. Sometimes, your home's water pressure is too high for the water heater to properly heat the water when it flows through. You may be able to restore your preferred hot water temperature if you adjust your water pressure valve to reduce the pressure of the water flow.

Water Temperature Is Cold Or Inconsistent

When your water heater fails to warm the water or produces inconsistent temperatures in the water, these are both causes for concern. In most cases, both of these problems are the result of inconsistent power supply to the heater.

If the standby light is lit, that means it's still getting consistent power. However, if the standby light isn't lit, you should call a water heater repair technician right away. They can test the power supply and replace your water heater if necessary to restore adequate power.

Water-Demanding Appliances Don't Work

Sometimes, tankless water heaters won't heat the water enough for your dishwasher or washing machine to work properly. If you notice that your appliances aren't doing what they should, it may be a problem with the temperature control on your water heater.

You can adjust the temperature control or you can adjust the valves so that the cold water flows more slowly to increase the hot water temperature.

Any time you experience problems with your tankless water heater, you should reach out to a tankless water heater repair technician right away. He or she can inspect and repair the problem. It's safer to have the work done by a certified repair technician than it is to try to do the work yourself.
