Common Tankless Water Heater Problems We Fix

Tankless water heaters are efficient and space-saving, but they aren’t immune to wear and tear. If you're searching for “tankless water heater repair near me”, chances are you're experiencing one of the issues below:

No Hot Water

This is the #1 call we get. If your unit is running but not heating, it could be a problem with the ignitor, gas valve, or sensor. We’ll get to the root cause quickly.

Fluctuating Water Temperature

Hot, then cold, then hot again? It’s frustrating and often caused by a dirty heat exchanger, flow sensor issue, or mineral buildup from hard water—something many Chula Vista homes deal with.

Error Codes

Is your unit flashing a code you don’t understand? Don’t panic. We’ll diagnose the issue and walk you through the fix in simple terms.

Unit Shuts Down

If your tankless system keeps turning off mid-shower or after a few minutes of use, it could be a safety shut-off caused by overheating or poor ventilation.

Water Leaks

Tankless water heaters can develop small leaks at fittings or from internal parts. Left unchecked, these can cause water damage or corrosion.

Not Sure If It’s Time to Call?

Here are a few signs it’s time to reach out for Chula Vista, CA, tankless water heater repair:

  • You have to reset your unit frequently
  • Your water takes too long to get hot
  • You hear clicking, whining, or rumbling noises
  • Hot water cuts out when using multiple fixtures
  • You notice a drop in water pressure with hot water only


Even if the problem seems small now, catching it early can save you from a full tankless water heater replacement later.
