Signs of a malfunctioning water heater
Your water heater plays a crucial role in providing hot water for your daily needs. However, over time, it may encounter issues that can disrupt its performance. By being aware of the signs of a malfunctioning water heater, you can quickly identify problems and take the necessary steps to resolve them.
One common sign is a sudden loss of hot water. If you find yourself shivering in the shower despite having a properly functioning water heater, there may be an underlying issue. Additionally, strange noises coming from your water heater, such as rumbling or popping sounds, can indicate sediment buildup or a faulty heating element. Leaks around the water heater or rusty water coming from the taps are also red flags that something is amiss.
Don’t panic! Instead, read our water heater troubleshooting tips and the solutions to the most common water heater problems.
No Hot Water
Your idea of starting the day off right includes a cup of steaming coffee and a hot, luxurious shower. What do you do when the hot water runs out? The solution to your hot water dilemma depends on whether you have a gas or electric hot water heater. If it’s gas, the first thing you should do is make sure you have gas access. If you suspect there’s no gas, call the gas company.
Next, verify the pilot light hasn’t blown out. If it’s not the pilot light, check the thermocouple. The thermocouple is a safety device that stops gas flow when the pilot light goes out. Sometimes the thermocouple just needs an adjustment so that the tip lines back up with pilot light flame.
According to the experts in water heater repair, for electric hot water heaters, start troubleshooting with a quick reset. Turn off the water heater for a few minutes and then turn it back on. Wait about ½ hour and see if your water heats up. If that doesn’t work, perform a hard reset by shutting off power to the water heater at the circuit breaker box. Once you flip the switch back on, if it doesn’t remain fully on, you may have a bad circuit breaker.
Maybe you have hot water, but it doesn’t stay hot long enough for you to finish your shower. Continue reading and find out why that happens.
Not Enough Hot Water
When you run out of hot water before the shower is over, there may be more than one problem. The size of your hot water tank determines how much hot water you have available. If the tank is too small for your heating needs try the following tips:
- Don’t shower, run the dishwasher, and wash clothes at the same time.
- Turn your water heater temperature up to the 120-140 degree range.
- Keep track of hot water usage.
Keep in mind that your household needs 75% of your water heater’s capacity for hot water. If you need 30 gallons of hot water and you have a 40-gallon tank, you’re fine. If your hot water usage is more than 75% of the water heater’s capacity, consider installing a bigger water heater.
It’s also possible you have a burner problem. Look at the burner flame and note the color. The flame should be bright blue with a yellow tip. If not, you’re dealing with inefficient combustion. The burner is always checked as part of your routine water heater maintenance. If you haven’t scheduled your service appointment yet this year, you’ll want to make it a priority.
You Have Rusty Water
When you turn on the tap, you expect clear water, but what happens when it’s rusty brown? Rusty water usually means you have a build-up of sediment in the hot water heater. Sediment comes from traces of dirt and rust in your water supply. It accumulates and then settles on the bottom of the tank.
When you run the hot water, you disturb the sediment and get a blast of rusty water. This is an easy fix! Drain the water heater to flush out the rust. If that doesn’t work, you may need an anode rod replacement. When you can’t get rid of rusty water by flushing it out, it’s time for a call to your favorite plumber.
Temperature Too Hot or Cold
No one enjoys a shower when the temperature jumps back and forth between too hot and too cold. Try these troubleshooting tips for your wishy-washy hot water tank. First, check your thermostat settings. Didn’t know you could adjust the thermostat on your water heater? Then this is good news for you!
Generally, the ideal temperature for hot water heaters is 120 degrees Fahrenheit. Adjusting the temperature isn’t difficult, especially if you have a water heater with a dial thermostat. If your thermostat is hidden behind a panel, grab two screwdrivers—a Philips head and a flat head. After removing the panel with the Philips head screwdriver, use the flathead to adjust the thermostat.
A River Runs Through Your Home

- Rust build-up
- Broken drain valve
- Faulty T&P valve
- Condensation
Most pipe leaks have easy fixes that your plumber can handle for you. Unfortunately, if your water tank itself is leaking, it’s considered fatal and you’ll need a new hot water heater.
What’s That Awful Smell?
The smell of rotten eggs when you turn on the hot water usually means you have a problem with anaerobic bacteria. When this type of bacteria comes in contact with your anode rod, it stinks!
Try this easy DIY fix for the stench:
- Turn off the cold water valve.
- Drain some of the hot water.
- Disconnect the metal hose.
- Pour 1 cup of 3% hydrogen peroxide for every 10 gallons your water heater holds.
- Reconnect the metal hose.
- Turn the cold water valve on.
- Let it sit for several hours.

The Noisy Hot Water Heater
Water heaters are often ignored until they run out of hot water or make weird noises. Some noise is normal, like the crackling sounds made by a gas water heater. Others can indicate a need for action on your part. Popping sounds mean you have sediment build-up. Use the tips we shared about flushing the tank! If your water heater makes sizzling sounds, you may have a leak. The sizzling noise means water is dripping onto the burner. For this noise, call your plumber. If you hear screeching, check your inlet control valve. If it’s only halfway open, turn the valve so it’s wide open.
DIY solutions for water heater issues
Before calling a professional plumber, it’s worth attempting some do-it-yourself solutions to troubleshoot your water heater problems. Here are some step-by-step instructions to tackle common issues:
- Relighting the pilot light: If your gas water heater’s pilot light goes out, you can relight it by following these steps:
a. Turn off the gas supply to the water heater.
b. Locate the pilot light assembly and turn the control knob to the “pilot” position.
c. Press and hold the control knob down while using a long-reach lighter to ignite the pilot light.
d. Continue holding the control knob down for about a minute to allow the thermocouple to heat up.
e. Release the control knob and turn it to the “on” position. Your pilot light should stay lit now.
- Adjusting the thermostat: If your water temperature is not consistent, you can try adjusting the thermostat:
a. Locate the thermostat panel on your water heater.
b. Use a screwdriver or the designated tool to access the thermostat controls.
c. Gradually increase or decrease the temperature setting to achieve the desired water temperature.
d. Check the water temperature after a few hours to ensure it is at the desired level. Adjust further if necessary.
- Flushing the tank: To remove sediment buildup from your water heater tank, follow these steps:
a. Turn off the power supply for electric water heaters or gas supply for gas water heaters.
b. Connect a garden hose to the drain valve at the bottom of the tank and place the other end where the water can safely drain.
c. Open the drain valve and allow the water to flow out of the tank. Be cautious as the water may be hot.
d. After draining the tank, close the drain valve and refill the tank by turning on the water supply.
e. Turn on the power or gas supply and allow the water heater to heat up before using hot water.
Importance of regular inspections and servicing
Regular inspections and servicing are essential to maintain the optimal performance of your water heater. It’s recommended to have a professional plumber inspect your water heater annually or as recommended by the manufacturer. Here’s why regular inspections are important:
- Early detection of issues: A professional plumber can identify potential problems during an inspection before they escalate into major issues. Timely detection allows for prompt repairs, preventing further damage and costly repairs.
- Safety assurance: Water heaters, especially gas-powered ones, involve potential safety hazards. Regular inspections ensure that all safety features, such as the pressure relief valve and gas connections, are functioning correctly, reducing the risk of accidents.
- Prolonged lifespan: By addressing minor issues and conducting necessary maintenance tasks, regular servicing can significantly extend the lifespan of your water heater. This saves you money in the long run by delaying the need for a replacement.
- Warranty compliance: Some water heater manufacturers require regular inspections and maintenance to keep the warranty valid. Failing to comply with these requirements may result in voiding the warranty, leaving you responsible for repair costs.
Don’t overlook the importance of professional inspections and servicing, as they play a crucial role in keeping your water heater in top condition and ensuring your safety.
