A loose water heater element can cause a humming sound
Electric water heaters don’t have gas burners. Instead, they have at least one electrically powered heating element associated with a thermostat.

Screeching sounds can signal restricted water flow
A screeching water heater noise is a sign that water flow is restricted, either at the valve letting water into the heater (the inlet control valve) or at a valve connected to water in the home.

Heat traps or check valves can create a ticking or tapping sound
Many water heaters have heat traps or check valves in pipes at the top of the heater to reduce wasted heat. These special-shaped valves trap hot water and encourage only cool water to flow back into the heater. This helps with water heater efficiency and ensures that water flows in the right direction.
