Signs You Need Tankless Water Heater Repair

In many cases, your system will show warning signs before it stops working entirely. Paying attention to these changes can help you schedule a repair before the problem gets worse.

You may need professional service if you notice:

  • Inconsistent water temperature
  • Reduced water pressure from hot taps
  • Error codes on the display panel
  • Unusual noises from the unit
  • Water leaks near the unit
  • No hot water at all

Continuing to run a malfunctioning system can lead to more extensive damage, so schedule tankless water heater repair ASAP if you notice any of the signs above.

Tankless Water Heater Problems We Fix

Tankless water heaters are built to be durable, but they still require maintenance and occasional repair. Mineral buildup, worn components, and electrical issues can all interfere with performance. Our team is equipped to diagnose and resolve a wide range of tankless water heater repair needs, including:

  • Mineral scale buildup in the heat exchanger: Hard water can cause scaling that reduces efficiency and restricts water flow.
  • Ignition or flame failure: Problems with the burner assembly or ignition system can prevent the unit from heating properly.
  • Clogged inlet filter or water line restrictions: Debris or sediment can limit water flow through the system.
  • Faulty temperature sensors or thermostats: Malfunctioning sensors can cause inconsistent water temperatures.
  • Ventilation or exhaust blockages: Improper venting can lead to safety shutoffs or performance problems.
  • Electrical component failure: Control board issues or wiring problems can disrupt normal operation.

Because tankless systems are designed to operate on demand, even a small issue can affect performance quickly. Quick repair helps prevent further damage and protects the lifespan of your unit, so call our team right away!

Tankless Water Heater Repair FAQs


That depends on the age of your unit and the nature of the problem. If the system is relatively new and the issue is isolated, repair is often the most practical option. For older systems with recurring problems, replacement may be a more cost-effective long-term solution.

Routine water heater maintenance plays a big role in protecting your system. Scheduling annual tune-ups allows small issues to be addressed before they become larger repairs, helping your unit operate reliably and efficiently for years to come.

Over time, minerals in the water can build up inside the system, especially in areas with hard water. Flushing the unit helps remove that buildup and keeps internal components operating efficiently. Regular flushing can also help maintain performance and extend the life of your tankless system.

The entire team at LePrevost is first class! From the owner to all of the employees I’ve worked with, they’ve been courteous, responsive, professional and a good value.

Liv D.

Furnace started acting up during the coldest day of the year and they were able to send someone to fix it without having to wait days or weeks. Thank you!

Phil T.

I received outstanding service from LePrevost. Very quick response regarding an emergency. Problems solved! This is the best service company I have used in many years.

Roger L.

Very responsive and repaired all I needed in 30 mins. After calling multiple plumbers around the area who never called me back, I found LePrevost through a google search. I was very happy with the technician who fixed a leak in the shower and replaced a toilet pump.

Manuela J.

Over the last several years I have had issues with my furnace. The last 2 times they were emergency calls. Both times the same technician showed up and found the issue right away and took care of the problem. The technician was very knowledgeable and professional.
