Signs Your Tankless Water Heater Needs Repair

Call Action for repairs if you notice any problems with your tankless water heater, such as:

  • Lukewarm or cool water: A malfunctioning thermostat, a faulty gas valve, a damaged heating element, or a clogged heat exchanger can prevent the water from heating adequately.
  • The water heater shuts off repeatedly: If your water heater isn’t supplied with the correct amount of water due to a clogged water filter or heat exchanger, it will shut off prematurely as a safety feature.
  • Low hot water pressure: Over time, sediment and mineral accumulations can build up in the heat exchanger, restricting the flow of hot water.
  • Poor water quality: If your hot water is discolored, smells odd, or has sediment, there may be a problem with the water heater, its filter, or your water supply.

Tankless Water Heater FAQs

What is the life expectancy of a tankless water heater?

With proper maintenance and regular flushing of the heat exchanger, you can expect a tankless water heater to last 20 to 25 years or longer. To get the most from your tankless water heater, schedule maintenance once a year, change your water filter often, service your water softener, and call our team at Action for repairs as soon as your notice any problems.

What are the most common problems with tankless water heaters?

Easily, the most common problem in tankless water heaters is mineral accumulation or limescale in the heat exchanger. This can usually be prevented with periodic flushing of the heat exchanger and routine maintenance. Other common problems include igniter or flame sensor failures, faulty gas valves, a clogged exhaust, faulty thermostats, damaged heating elements, or leaks.

What do you do when your tankless water heater stops working?

If your tankless water heater stops working, ensure the circuit breaker is not tripped, then check your water filter and replace it if necessary. Make sure the air intake and exhaust are not blocked and the gas valve is open. Call our Action team for repairs if it still won’t function properly.
