Rumbling, popping, or banging noises during heating

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Heavy mineral sediment on bottom of tank, scaled heating elements, high hardness water

Safety first: Turn OFF power or gas and allow water to cool.

Descaling procedure:

Connect a hose to the drain valve and drain several gallons, then close valve.
Open cold supply briefly to stir sediment, then drain again. Repeat until water runs clear.
For electric models, remove lower element and use a wet/dry vacuum with a small tube to remove sediment from the bottom.
Consider installing a water softener or performing annual flushes to prevent recurrence.
