How to Tell When Your Tankless Water Heater Needs Repairs

Many homeowners don’t realize something is wrong with their tankless water heater until the hot water suddenly stops flowing. But there are often early warning signs that indicate a problem is brewing. If you notice any of the following, it’s time to schedule tankless water heater repair:

Inconsistent Water Temperature

If your water goes from hot to cold unexpectedly, or fluctuates while you’re using it, your tankless water heater may have a faulty thermostat, mineral buildup, or a malfunctioning heat exchanger.

No Hot Water

A complete lack of hot water is a clear sign that something’s wrong. This could be due to electrical issues, gas supply problems, or internal component failure.

Error Codes on Display Panel

Most modern tankless water heaters come equipped with digital displays that show error codes when something isn’t working properly. These codes help our technicians quickly identify and address the issue.

Strange Noises

Hissing, banging, or rumbling noises coming from your tankless unit may be caused by scaling, loose parts, or mechanical wear.

Reduced Water Pressure

If your hot water flow feels weaker than usual, mineral buildup or a clogged filter may be to blame.

When to Consider Replacement Instead of Repair

Sometimes, repairing an old or severely damaged tankless unit isn’t the most cost-effective option. If your water heater is:

  • Over 15 years old
  • Requiring frequent repairs
  • No longer meeting your household’s hot water needs
  • Showing signs of corrosion or internal damage


…we may recommend a replacement instead. We’ll help you weigh the pros and cons and guide you through the installation process if a new unit is the better choice.

Prevent Costly Repairs With Regular Maintenance

Tankless water heaters may last up to 20 years, but only if they’re properly maintained. Without regular care, mineral deposits from Highland Park’s hard water can accumulate inside the system, causing premature wear and tear.

At Ravinia Plumbing, we offer preventative maintenance services to keep your tankless water heater running efficiently year-round. During a maintenance visit, we’ll:

  • Flush the system to remove scale buildup
  • Inspect filters and clean intake screens
  • Check gas lines or electrical connections
  • Test the heat exchanger and thermostat
