Gas Water Heater Repair in Lake Stevens, WA
Most gas water heater problems trace back to a small group of parts: the thermocouple or flame sensor, the gas control valve, the burner assembly or the venting. A technician can usually pinpoint the failed part in one visit and repair it, as long as the tank itself is sound.

If you smell gas
Leave the house, avoid switches and phones inside, and call 911 or your gas utility from outside. Do not try to relight anything until the smell has been checked.
Signs your gas water heater needs repair
The pilot light is out, won't light or keeps going out.
A worn thermocouple or flame sensor is the most common cause. Drafts and venting problems can also blow a pilot out. Our guide to a water heater pilot light that is out shows how to check it.
Water is lukewarm, or the hot water runs out fast.
That points to a weak burner, a failing gas control valve or a tank with heavy sediment.
The flame is yellow, orange or sooty.
A healthy burner flame is mostly blue. Yellow flames or soot around the top of the unit suggest poor combustion and need prompt attention.
The unit rumbles, pops or takes longer to heat.
Sediment on the tank bottom insulates the water from the burner, so the tank overheats in spots and the burner runs longer.
There is rust at the base or rust-colored water.
Corrosion low on the tank can mean the tank itself is failing, which changes the repair-or-replace answer.
Seeing one of these?
Call and describe it. A technician will tell you what to expect.
What usually causes gas water heater problems
| What you notice | Usual cause | Usual repair |
|---|---|---|
| Pilot won't stay lit | Worn thermocouple or flame sensor, drafts, blocked vent | Replace the sensor; clear or correct the venting |
| Pilot lit, burner won't fire | Failed gas control valve or dirty burner orifice | Clean the burner or replace the gas control valve |
| Water never gets hot | Failed thermostat inside the gas control, low gas supply | Replace the gas control; check gas supply |
| Not enough hot water | Sediment buildup or a broken dip tube | Flush the tank; replace the dip tube |
| Rumbling or popping | Sediment hardened on the tank bottom | Flush; if heavily scaled, weigh replacement |

Repair or replace a gas water heater?

Questions about gas water heater repair
Still have a question? Call and ask a technician directly.
Is it safe to relight my own pilot light?
Most heaters print lighting instructions on the label, and following them is generally fine. If the pilot will not stay lit, or you have ever smelled gas near the unit, stop and call a technician instead of retrying repeatedly.
How long does a gas water heater repair take?
Many repairs finish in a single visit. Timing depends on the diagnosis and whether the part is on the truck or has to be ordered.
Can a bad gas water heater cause carbon monoxide problems?
Yes. Blocked vents, poor combustion or cracked flue parts can let combustion gases into the home. Working carbon monoxide alarms matter, and any suspected CO problem should be treated as urgent.
Why does my gas water heater pilot light keep going out?
Usually a worn thermocouple or flame sensor, a draft, a dirty pilot orifice, a partly blocked vent or a failing gas control valve. How soon it goes out after lighting helps tell them apart, and a technician confirms the cause by testing.
Do you repair every brand?
We service the major brands, including Rheem, A. O. Smith, Bradford White and State. Have the model number from the rating label ready when you call.
