Water Heater Pilot Won’t Stay Lit (Washington)

Water Heater Pilot Light Keeps Going Out, Washington Troubleshooting Guide

A pilot light that won’t stay lit is one of the most common water heater issues in Washington. Moisture, rusted burner assemblies, and drafts from older homes can cause ignition failure, overheating, and repeated shutdowns. Liberty Tradesmen provides fast, same‑day water heater repair throughout Snohomish County.

Why Water Heater Pilot Lights Go Out More Often in Washington

Washington’s climate and home construction create unique challenges:

  • Moisture interfering with combustion
  • Rusted burner assemblies reducing flame stability
  • Drafts from older homes blowing out the pilot flame

These conditions make regular maintenance and proper diagnostics essential.

Common Causes of Pilot Light Failure

  • Dirty or weak thermocouple
  • Faulty gas control valve
  • Clogged burner assembly
  • Drafts blowing out the flame
  • Sediment overheating inside the tank

Each of these issues can cause the pilot to light briefly and then shut off.

Washington‑Specific Causes

  • Moisture affecting combustion
  • Rusted burner assembly
  • Drafts from older homes

These factors often accelerate wear on ignition and safety components.

Symptoms Washington Homeowners Often Notice

  • Pilot lights but goes out after a few seconds
  • No hot water
  • Burner will not ignite
  • Rotten egg smell (possible gas leak, call immediately)

If you notice any of these symptoms, the water heater is shutting down for safety.

Professional Fixes for Pilot Light Problems

  • Clean or replace the thermocouple
  • Clean the burner assembly
  • Replace the gas control valve
  • Flush the tank to remove sediment

A full diagnostic ensures the correct repair and prevents repeat failures.

When Repair Isn’t Possible

If the water heater is 10–12+ years old, sediment overheating may have damaged internal parts such as the burner chamber, flue baffle, or gas valve. At this stage, replacement is typically more reliable and cost‑effective.
