GE water heater makes popping or rumbling noises during heating.

Safety: Turn off power or gas and allow water to cool before flushing.

Steps to reduce popping noises:

• Flush the tank: Turn off cold supply, connect a garden hose to the drain valve, open a hot faucet, and open the drain valve to flush sediment until water runs clear.
• Repeat if needed: Close drain, open cold supply to stir sediment, then drain again.
• Inspect elements (electric): Remove and inspect heating elements for heavy scale. Replace with GE-compatible elements if badly coated.
• Consider water treatment: In hard water areas, consider a softener or schedule regular flushing (every 6–12 months).
