For many homeowners, heater repair may be a challenging task that requires experience and skills. However, it isn’t that hard. There are many reasons why a hot water heater in your house fails, such as leaky valves, broken water tanks, damaged elements or inefficient thermostats – yet you can easily address these problems in some simple steps.
Before getting started, make sure to prepare the following tools:
– Teflon tape
– Replacement elements
To ensure safety while repairing a heater, it is always better to turn the circuit breaker off. Otherwise, the 240V currents might cause a deadly electrical shock when you make a mistake.
Fix the valve
First, you should lift the spring lever and examine the drain or relief valves to look for any damage or leaks. If the relief valves just allow a few drops of water to come out or do not flow out any water, then they need to be changed.
To fix a leak, simply use a wrench to remove the valve and pipe tape, then cover this area with new Teflon tape. Make sure to wrap at least 3 times and re-install the valve.
If you need to replace it, empty the tank and use a wrench to pull it out. Buy a new valve and place it in the same location.
Fix the thermostat
Use the service manual to find out the location of the thermostat in your heater. To reach this part, you might need to remove the access panel.
To know whether the thermostat fails, the best way is to take a continuity test. First, remove the wiring and find all terminals of this element, then use the multimeter to measure resistance.
If the multimeter indicates infinity, the thermostat on your heater is still operating properly. But if the result is zero, it’s time to buy a new one and re-install it.
Fix other heating parts
If neither the thermostat nor the valve is the reasons for your water heater’s failure, it’s time to check other heating parts. Just like the previous step, use a service manual to locate and remove the access panel to reach these elements. Pull out a wire and use the multimeter to measure an RX1000-resistance. If the result is zero, you need to replace it.
The replacement process of heating parts is very simple. First, make sure to drain all of the water in the tank. Then, you need to detach the part by removing the bolts that keep it in a fixed position. Place the new one in the same location and wire it to the water heater properly. If you aren’t sure how to insert it, keep in mind to follow simple steps that are described in the service manual. Lastly, do not forget to change the installation gasket as well.
As you can see, heater repair can be very simple with the help of a service manual. By following our guide, you will not need to be worried about any problems with your heater in this winter season.
