High pitched noise from rv water heater.

When the element is off the caked sediments trap water beneath them and the water heats until it makes a cracking or popping sound as it is forced through the deposits. This is not a defect with the water heater or components. This is more common on older units and the noise increases as the deposit layer thickens. This is normal in operations and will not affect the water heater s function or any components.

If you ever hear a high pitched noise coming from your water heater it could be an indication that the tank needs to be flushed already. Water heater troubleshooting is as matter of finding the problem by eliminating possible problems. Here s what you should do. Debris can get stuck in the hot water outlet creating a whistling noise.

Armed with this knowledge it was easy to deduce that the element was the cause. The noise was only present when the water heater was using electric power not lp gas. If it is hot to the touch this may be the source of the sound. As sediments accumulate at the bottom of the tank your water heating system exerts more effort and energy in warming water.

It also only happened during the heating process when the electrical heating element was active. 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. Thus the high pitched noise is produced. If you are hearing a high pitched sound then check out these possible solutions.

Sediments collect around the element tubes of a water heater. This noise may also be produced by a failing pressure relief valve or thermostat so they will have to be changed. Check this emergency relief valve. We have a new potting on the circuit board and new circuitry underneath that causes a humming noise.

Either way call your dealer asap. It happened again this afternoon and quit immediately when i pulled the disconnect on my electric water heater. Step 1 check the pressure relief valve. Try lowering the temperature.
