No Hot Water? Here’s Why — and How to Get It Back
No hot water is usually caused by a tripped breaker or reset button (electric), a pilot light that’s gone out (gas), or a failed heating element, thermostat, or gas valve. Start by checking your breaker and the red reset button on the tank. If heat doesn’t come back, the unit needs service. In Westminster, call (443) 247-4113 for same-day help.

Why do I suddenly have no hot water?
The cause depends on whether your water heater is electric or gas:
Electric water heaters:
– Tripped breaker — the most common and easiest fix.
– Tripped reset button — the red button on the upper thermostat popped.
– Failed heating element — one or both elements burned out (you may get some warm water if only one failed).
– Bad thermostat — not signaling the elements to heat.
Gas water heaters:
– Pilot light out — a draft, dirty thermocouple, or gas interruption.
– Faulty thermocouple — won’t keep the pilot lit.
– Gas supply issue — closed valve or utility outage.
– Failed gas control valve.
Either type:
– Sediment buildup insulating the tank.
– Leaking tank dumping heated water (see water heater leaking).
– Unit at end of life — most last 10–15 years.
What you can safely check yourself
Try these before calling — they fix a surprising number of “no hot water” calls:
- Check the breaker (electric): flip it fully off, then on.
- Press the reset button (electric): remove the upper access panel; press the red button. If it trips again, stop — that’s an electrical fault for a pro.
- Check the pilot light (gas): if it’s out, follow the relight instructions on the tank’s label. If it won’t stay lit, you likely need a thermocouple.
- Confirm the gas is on (gas): make sure the supply valve is open and other gas appliances work.
- Check the thermostat setting: it should be around 120°F.
⚠️ Stop and call a pro if: you smell gas (leave the house first and call your gas utility), the reset button keeps tripping, you see scorching or water around the unit, or the breaker won’t stay on. These are safety issues — don’t DIY them.
When to call a pro

No hot water FAQs
Why do I suddenly have no hot water?
Most often a tripped breaker or reset button (electric), a pilot light that went out (gas), or a failed heating element or thermostat. Check the breaker and reset button first; if heat doesn’t return, the unit needs service.
How do I reset my water heater?
On an electric unit, turn off the breaker, remove the upper access panel and insulation, and press the red reset button. If it immediately trips again, call a pro — that indicates an electrical fault.
Why is there no hot water but the heater is on?
Likely a failed heating element or thermostat (electric) or a bad gas control valve (gas) — the unit has power but isn’t transferring heat to the water. Sediment buildup can also be the cause.
Can I get no hot water from a tripped breaker?
Yes. A tripped breaker cuts power to an electric water heater entirely. Reset it once; if it trips again, there’s an underlying fault that needs a technician.
Is no hot water an emergency?
It’s usually not dangerous, but it’s urgent for your household. If it’s paired with a gas smell, a major leak, or sparking, treat it as an emergency — shut off the unit and call for help.
