Common Signs You Need Tankless Water Heater Repair

While tankless units are low-maintenance by design, they still require occasional repairs. Here are the most common indicators something’s wrong:

• Water doesn’t get hot – If you’re only getting lukewarm or cold water, it may be a failed heating element, ignition issue, or sediment buildup inside the unit.
  
  
• Fluctuating temperatures – Inconsistent water temperature often stems from a clogged heat exchanger or malfunctioning flow sensor.
  
  
• Error codes – Modern tankless heaters come with diagnostic displays. If you see an error code, it’s best to contact a professional to interpret and fix the issue.
  
  
• Reduced water pressure – Mineral scaling or debris in the inlet filter can restrict flow.
  
  
• Strange noises – Unusual banging, whining, or hissing can signal internal damage or scale buildup.
  
  

If you're noticing any of these symptoms, call Thorough Plumbing at 844-933-5874 before minor issues become major expenses.
