Why Is My Water Heater Making a Crackling Noise? Water Heater Troubleshooting
May 06, 2021
It’s easy to take a water heater for granted. It's not until you step into an ice-cold shower that you realize how vital it is in your daily life. If your water heater suddenly starts making strange noises—such as a crackling, popping, or humming sound—it’s time to pay attention.
But take heart; a noisy appliance doesn't always mean big fixes (and big money). Sometimes the noise is just related to the changes in temperature. Read on to know whether or not your water heater making a crackling noise is serious and what you need to do.
Maintenance is key
Maintenance is critical in keeping your water heater running smoothly and efficiently. When most homeowners think of maintenance, they think of their heating and cooling system, but spending time and a little money on routine maintenance for your water heater can help save you many headaches and big bucks down the road.
What's that noise?
If your water heater starts popping, crackling, or rumbling, it may signal that sediment build-up or mineral deposits are present at the bottom of the water heater’s tank. This can especially be a problem for homes with hard water (a water softener can help).
The best way to avoid this problem is to flush the tank of your water heater. Doing this once a year is a great way to increase the performance and efficiency of your unit, which can lead to a longer lifespan and lower energy bills.
Crackling or Sizzling
Crackling or sizzling noises may indicate that there is condensation on the burner. A leak could cause this, so it is essential to inspect the ground around your water heater for signs of moisture.
Humming
A humming sound generally is caused by water flowing around the heating element. Knocking and tapping sounds can be caused by pipes that rattle against the sides when water pressure is suddenly changed, like when a toilet is flushed or the dishwasher cycles on or off.
Screeching or Screaming
One sound that may worry homeowners the most is a screeching or scream-like sound. While it may be startling to hear, this is usually caused by a valve that is not fully released, forcing the water through too small of an opening.
