No Hot Water? What to Check Before You Call
Before you call for a repair, here are the safe checks any homeowner in Loudoun or Fairfax County can run on a gas or electric water heater with no hot water.
Start With Power and the Breaker
For electric water heaters, start at the electrical panel. A tripped breaker is the single most common reason a tank stops heating, and it is safe for any homeowner to check. Flip it fully off, then back on. If it trips again right away, stop there and call, because that usually means a short in the heating element or wiring.
Check the Pilot Light on Gas Units
Gas water heaters have a sight glass or a small window near the bottom of the tank where you can see if the pilot is lit. If it is out, most tanks have relight instructions printed right on the gas control valve. Follow them exactly and never force a valve that will not turn. If the pilot will not stay lit after a couple of honest attempts, or you smell gas at any point, stop and call us instead of trying again.
Check the Thermostat Setting
Sounds basic, but it happens constantly. Someone or something bumps the dial down, or a setting got changed during an unrelated repair. On both gas and electric units, the dial is usually behind a small access panel on the side of the tank. Set it to around 120 degrees and give it an hour or more before you assume the unit is broken.
The Reset Button and a Failed Element
Electric water heaters have a small red reset button, usually under an upper access panel, that trips when the water runs too hot. It is called the ECO, short for energy cutoff. Turn the water heater's breaker off first, since there is 240-volt wiring behind that panel, then open it and press the button once. If it trips again, or you have hot water that runs out fast, you are likely looking at a failed heating element, and that is a job for a licensed technician, not a DIY fix, because it means opening the tank's electrical side.
Signs of a Leak: Stop and Call
Water pooling at the base of the tank, rust-colored water, or a popping and rumbling sound are all signs you should stop checking and call. A leaking tank can fail completely with very little warning, and a water heater holds 40 to 50 gallons that will end up on your floor. If you see any of these signs, shut off the water supply valve above the tank and call us at (571) 761-5379 before it gets worse.
Common questions
Is it safe to relight a gas pilot myself?
Yes, on most tanks, as long as you follow the instructions printed on the gas control valve exactly and you do not smell gas. If it will not light after a few tries, or it keeps going out, stop and call us. That is usually a thermocouple or gas valve issue, not something to force.
My breaker keeps tripping when I reset it. What does that mean?
A breaker that trips again right away usually means a short in the heating element or the wiring, not a simple overload. Resetting it over and over risks real electrical damage. Call us so we can test the element and wiring safely.
How do I know if it's the thermostat or the heating element?
If you get no hot water at all and the breaker and reset button check out fine, a failed element is more likely. If the water is lukewarm instead of hot, or you run out fast, either a thermostat setting or a weak element could be the cause, and we will test both before replacing anything.
