We have a new potting on the circuit board and new circuitry underneath that causes a humming noise. Armed with this knowledge it was easy to deduce that the element was the cause. If you are hearing a high pitched sound then check out these possible solutions. High pitched noise since this type of noise often involves pressure in your water heater the first step to solve the issue is to check the pressure relief valve and if it is working as it should the temperature will be lowered to lessen the pressure.

As sediments accumulate at the bottom of the tank your water heating system exerts more effort and energy in warming water. High pitched whine from electric water heater the noise i thought was coming from my ac this morning even though it seemed loudest near my water heater was actually my water heater.

Thus the high pitched noise is produced. Another cause for a noisy water heater either on gas or electric can be a plugged check valve. Possibly a loose connection on the water heater that is connected to the heat element or it could be the temp and pressure valve making that noise. It also only happened during the heating process when the electrical heating element was active.
