Steps in Testing and Repairing Electric Water Heater in Pre Manufactured Homes
Electric water heaters are the crucial components of most pre manufactured homes. They are essential devices in most new manufactured homes that generate hot water that is ideal for bathing. Water heaters are commonly prone to malfunctioning that can result in less heating or no heating at all. Moreover, a malfunctioning water heater will consume far greater amounts of current thereby increasing your monthly utility costs. Testing the heater is the first step to carry out for evaluating the issue that is persisting in the heater.
The heating element is the crucial component of an electric water heater that can be the cause of any heating problems. It is involved in heating the water and is a highly resistive material that converts the electric current that is passing through to generate heat. Any breakage in the element can cause disruption in the passing electricity, thereby affecting the heating function.
Repairing heating elements is easier and only requires strictly following the instructions. The following are the steps involved in testing and repairing the electric water heater.
- First, disconnect the heater from the power source and use a screwdriver to remove the cover that shields the thermostat and heating element. Strip away the plastic that shields the elements connections and check if the heater is successfully disconnected from the power.
- Disengage the wires that are connected to the element and use a meter probe set to measure ohms or resistance. Gently touch the terminals of the meter to the element screws and if the meter emits a beep or if the needle is moving, you can be sure that the element is in perfect working condition.
- If the meter does not move or beep, there could be an issue with the heating element, which requires replacing the entire unit. For this purpose, purchase a new heating element designed specifically for the type of heater that you have at home. Drain out the remaining water from the tank and disengage its wires before unscrewing the heating element.
- Install the new element into the screw it properly and then connect the wires to its terminals. Then fasten the cover of your heater and connect the water inlet and outlets terminals. Allow the tank to be fully filled with water before switching on the heater.
Other issues that water heaters will have other than the heating elements are with the thermostats. In such a scenario, carry out testing with the meter probe to determine if the thermostat is allowing current to reach the heating element. If the test fails, consider replacing the thermostat completely.
