Water Heater Stopped Working? Here’s What to Check
A water heater that suddenly stopped working is usually caused by a tripped breaker or reset button, a pilot light that went out (gas), or a failed heating element, thermostat, or gas valve. Start with the breaker and reset button. If there’s still no heat, the unit needs service. In Westminster, call (443) 247-4113 for same-day repair.
Why did my water heater stop working?
Electric: tripped breaker, popped reset button, burned-out element, or bad thermostat.
Gas: pilot light out, failed thermocouple, gas supply issue, or bad gas control valve.
Either: a leaking tank, heavy sediment, or a unit that’s simply reached end of life.
A water heater can absolutely “just quit” — almost always one of the causes above, not bad luck.
What you can check yourself
- Breaker (electric) — flip fully off, then on.
- Reset button (electric) — press the red button on the upper thermostat. If it trips again, stop and call a pro.
- Pilot light (gas) — if out, relight per the tank’s label; if it won’t stay lit you likely need a thermocouple.
- Gas supply (gas) — confirm the valve is open and other gas appliances work.
- Thermostat — set around 120°F.
⚠️ Smell gas? Leave the house and call your gas utility first. Reset keeps tripping or water around the unit? Call a pro — don’t keep resetting.

FAQs
Why did my water heater stop working?
Most often a tripped breaker or reset (electric) or a pilot light that went out (gas), followed by a failed element, thermostat, thermocouple, or gas valve. Check power/pilot first; if there’s still no heat, it needs service.
Can a water heater just stop working?
Yes — they fail suddenly when an element, thermostat, thermocouple, or gas valve goes, or when a breaker trips. It’s almost always a fixable cause.
How do I know if my water heater is dead?
If it has power/gas, the breaker and reset are fine, the pilot is lit, and it still makes no hot water, the heating components or tank have likely failed. A tech can confirm whether it’s worth repairing.
How do I reset a water heater?
Electric: turn off the breaker, open the upper access panel, press the red reset button. If it trips again immediately, call a pro.
