Why Is My Water Heater Not Heating?

Common reasons for no hot water and questions to ask before repair or replacement.

Educational information: This article is general plumbing information, not a diagnosis of a specific property.

Start With the Symptom

Plumbing problems often have more than one possible cause. Look for changes in flow, drainage, pressure, temperature, odors, moisture, staining, or fixture behavior. Document what you observe and when it happens.

Common Causes

Depending on the problem, possible causes can include buildup, damaged components, aging or corroded piping, foreign objects, poor drainage, pressure issues, or a failure elsewhere in the plumbing system.

When to Call a Plumber

Professional assessment is appropriate when the issue is recurring, inaccessible, causing water damage, affecting multiple fixtures, creating a sewage backup, or cannot be safely diagnosed.

What to Ask the Plumber

  • What is the likely source?
  • What inspection was performed?
  • What repair options are available?
  • What is included in the estimate?
  • What maintenance could prevent recurrence?
