What to Do When Your Water Heater Stops Working

Don’t Panic, Rancho Cucamonga – Here’s How to Get Hot Water Flowing Again

Waking up to an icy cold shower is nobody’s idea of a good morning. If you’re a Rancho Cucamonga homeowner suddenly faced with a water heater that isn’t doing its job, don’t panic. Water heaters can stop working for a variety of reasons, many of which have simple solutions. Before you start worrying about needing a brand-new heater, follow these steps to troubleshoot the problem. With a bit of luck (and maybe a quick fix), you’ll have hot water back in no time. And if not, don’t worry – Rancho Plumbing Pros is just a phone call away to help with water heater repair across Rancho Cucamonga, Upland, Fontana, and the surrounding area.

1. Immediate Steps to Troubleshoot Your Water Heater

   1. Check the Power or Gas Supply: The first thing to do is make sure your water heater is actually receiving power or fuel. For electric water heaters, go to your electrical panel and see if the circuit breaker for the heater has tripped. A tripped breaker is a common cause of an “off” water heater – if it’s tripped, reset it (flip it off and on again). For gas water heaters, check that the gas supply valve is open and see if the pilot light is lit. Most modern gas heaters have a small viewing window; if you don’t see a small flame, the pilot may have gone out. Follow your heater’s instructions to safely relight it (usually printed on the tank) or refer to the manufacturer’s manual. Important: If you smell a strong gas odor, do not try to relight anything – turn off the gas supply, leave your home, and call the gas company or a 24/7 emergency plumber immediately.

   2. Adjust the Thermostat & Hit the Reset Button: Sometimes the fix is as simple as a twist of a dial or push of a button. Check the temperature setting on your water heater’s thermostat. It might sound basic, but occasionally someone might have accidentally lowered the temperature (or set an electric heater to “Vacation mode” or a gas heater to “Pilot”). Make sure it’s set to your desired temperature (around 120°F is a good target for most homes). If you have an electric water heater, it likely has a reset button (often a red button on the thermostat or control panel, usually behind a small cover). Press the reset button firmly. This can often restart the heating cycle if a safety limit was tripped. After resetting, give the heater about 30 minutes and then test your hot water again.

   3. Look for Signs of Leaks or Damage: Do a quick inspection around your water heater tank. Do you see any puddles of water, dripping, or rust and corrosion on the tank or pipes? A leaking water heater not only fails to provide hot water, but it can also cause significant water damage to your home. If the tank itself is leaking (for example, from the bottom), that’s a serious issue – likely the tank has corroded through and the water heater may need to be replaced. Also listen for unusual noises; a loud popping or rumbling sound when the heater was last running could indicate heavy sediment buildup. In Rancho Cucamonga and other Inland Empire areas, we have moderately hard water, which means mineral deposits can accumulate in tank heaters over time. Sediment buildup can cause the heater to overheat and shut down. If you suspect sediment is an issue (you hear boiling sounds or sizzling), you could carefully drain and flush the tank to remove sediment – but if you’re not comfortable doing this, it’s best to call a professional.

   4. If the Pilot Still Won’t Stay Lit (Gas Heaters): Let’s say you got the pilot light back on, but it keeps going out or the main burner still isn’t firing. This usually means an internal component has failed – often a bad thermocouple or gas control valve. Unfortunately, that’s not a quick DIY fix. At this point, it’s time to call a professional to repair or replace the faulty part. (For tankless water heaters, if you see an error code on the display that you can’t clear by resetting the unit, note the code and get a plumber’s help.)

   5. Still No Hot Water? Call in a Professional: If you’ve checked the power/gas, reset the system, and made sure there are no obvious leaks or simple fixes, and your water heater is still not working, it’s time to call a Rancho Cucamonga water heater repair expert. Water heaters involve electricity, gas, and hot water under pressure – a combination that can be dangerous if you’re not trained. Continuing to tinker without results could worsen the problem or create a safety hazard. The good news is that experienced help is available 24/7. A professional plumber can diagnose whether it’s a bad heating element, a broken thermostat, a gas valve issue, or something else, and get it fixed or advise if a replacement is needed.
      

   Know When to Repair vs. Replace

   One question many homeowners ask is whether they should repair the existing water heater or invest in a new one. As a rule of thumb:

   • If your water heater is relatively new (less than 8-10 years old) and this is the first time it has failed, it’s likely worth repairing. Common repairs include replacing heating elements, thermostats, or thermocouples, which can be done quickly by a qualified plumber.

   • If the unit is older (10-15+ years), or if it’s leaking from the tank, replacement is often the better choice. Newer water heaters are more efficient, and an old tank that’s corroded is a ticking time bomb for a major leak. Rancho Plumbing Pros can help you compare the costs and benefits of repair vs. replacement so you can make an informed decision.
