Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
No gas smell? Note what the noise sounds like and when it happens, then turn the water heater’s gas control knob to OFF if it’s gas, or switch off its breaker if it’s electric.

Everything else about this problem
Is it an emergency?
Is a loud noise from an Amana water heater an emergency?
Usually not an emergency. A grinding, rattling or humming that has just started most often comes from a fan, motor, belt or loose panel. Stop using it and cut the power if the noise comes with a burning smell, smoke or sparks; if it runs on gas and you smell gas, leave and call the gas company or 911 from outside.
Symptoms & causes
Loud noises like rumbling, popping, or banging in an Amana water heater often indicate sediment buildup at the bottom of the tank. This sediment, typically calcium and magnesium deposits, superheats and then collapses as water boils around it, creating the disruptive sounds. Over time, excessive sediment can also reduce heating efficiency and potentially damage the heating elements or tank lining.
Tools & parts
You will need a garden hose for draining, a large bucket for initial water collection, and a flathead screwdriver or socket wrench for the drain valve. For more thorough flushing, a specialized water heater flush kit with a descaling solution can be beneficial. Additionally, a new anode rod, if replacement is needed, can extend the life of your Amana unit.
Safety first
Always begin by shutting off the gas supply to your Amana water heater at the main valve or turning off the circuit breaker for electric models to prevent accidental ignition or electrocution. Ensure the hot water supply valve is closed and allow the water to cool sufficiently before draining to avoid severe burns from scalding water. Wear appropriate personal protective equipment, including gloves and eye protection, to safeguard against hot water, sediment, and potential chemical splashes during descaling.
When to call a pro
If the loud noises persist after thorough flushing, or if you observe water leaks around the tank or connections, it indicates a more serious internal issue. A failing heating element or a compromised tank lining, especially in older Amana models, can produce similar sounds but requires professional testing and repair. Furthermore, issues with the pressure relief valve or a corroded dip tube are complex problems that are best addressed by a licensed plumber to ensure safety and proper function.
Questions people ask
Why does my Amana water heater make a popping sound?
Popping sounds are typically caused by sediment buildup at the bottom of the tank. As the heating element heats the water, trapped pockets of water within the sediment boil and then burst, creating the popping noise.
Can I ignore the loud noises from my Amana water heater?
Ignoring loud noises is not recommended as it can lead to decreased efficiency, higher energy bills, and potential damage to the heating elements or the tank itself. Addressing the issue promptly, usually through flushing, can prevent more costly repairs.
How often should I flush my Amana water heater to prevent noise?
It is generally recommended to flush your Amana water heater annually, or even semi-annually in areas with very hard water, to prevent sediment accumulation. Regular maintenance significantly extends the lifespan and efficiency of the unit.
