Call or text: 323-509-4738In West Hollywood and already know you need it replaced?

Safety first: if you smell gas, leave the house and call for help. Do not poke at gas or electrical parts inside the unit. The checks below are the safe, outside-the-unit ones only — a pro decides repair vs replacement.
Why there's no hot water at all
Usually the heat source stopped, not the whole tank. On a gas unit, that's often a pilot light that's out, or a thermocouple / igniter that won't stay lit. On an electric unit, it's often a tripped breaker, a tripped high-limit reset, or a failed upper heating element — if the upper element fails, the cycle never gets to the lower one, so you get nothing hot.
Why it runs out fast
That's usually capacity lost inside the tank, not the burner. Sediment builds up at the bottom over years and steals usable volume. A failed lower element gives you a short burst of hot water, then cold, because only the top of the tank is heating. A broken dip tube can also mix cold water into the hot outlet. On a tankless unit, the same complaint usually means scale in the heat exchanger cutting heat transfer.
Tank vs tankless — they break differently
Tank: fails mostly by corroding, leaking, or filling with sediment. A tank leaking from the tank itself, not a valve or pipe, usually means replacement, not repair.
Tankless: fails mostly by scale, flow, or ignition problems. Low flow may not even trigger it, and hard water scale can cause lukewarm swings or shutdowns until it's descaled.
Other signs, plainly
- Popping / rumbling: usually sediment on the tank floor trapping steam bubbles.
- Lukewarm at every tap: thermostat setting, or a failed thermostat / element.
- Too hot: thermostat set too high — scald risk, turn it down and get it checked.
- Rusty / brown water: often internal corrosion, or a worn anode rod.
- Rotten-egg smell: bacteria reacting with the magnesium anode rod in the tank.
- Leaking from the top: often a valve or inlet connection. Leaking from the tank seams is a different, bigger problem.
When is it repair, and when is it toasted?
Many units can be repaired — a thermostat, an element, a thermocouple, a descaling. But an old, corroded, leaking tank often can't be saved, and that's when replacement is the honest answer. Age, leaks, and repeated failures are the clues a pro uses. No page can diagnose your unit from here — that's what the call is for.
FAQs
Why do I have no hot water suddenly?
Most often: pilot out (gas), breaker tripped (electric), or a failed element / thermostat. Check the breaker and the pilot viewing window only if it's safe to do so.
Why does my hot water run out in the shower?
Usually sediment, a failed lower element, a broken dip tube, or a tank that's too small for the household now.
Why is my water heater making popping noises?
Usually sediment buildup. It needs attention before it gets worse, but it's not automatically an emergency unless it's leaking.
Should I repair or replace it?
If it's leaking from the tank, very old, or keeps failing, replacement is usually the call. A pro who sees the unit makes that call, not a website.
