If the root cause of a problem is diagnosed properly, it is as good as solving it. Once the cause of a problem is recognized, it is easy to nullify that cause. The list of common water heater problem is not very long. Even if some of them will need the help of a professional, most of them are simple enough for a resourceful layman to solve them.
Water is not hot enough
If your gas tankless water heater does not heat up the water, you’d better see if the pilot light is on. If not, you can re-light it following the manufacturer’s instruction manual. Usually, if you work the temperature control dial up and down a few times, the pilot light will come on by itself. If that does not happen, you may have to get a professional to check the thermocouple.
Sometimes the pilot light is relit but it does not stay lit for long. This means your burner is clogged and needs an immediate cleaning. Take out the burner and using a wire, clean its pores which are clogged with dirt and debris.gas-tankless-water-heater-problems
If the gas line you are using is below the required size, it will also cause problems in providing the burner with adequate supply of gas. It is imperative that you should use the size recommended by the manufacturer.
If the tankless water heater is an electrically operated one you need to check the electric connections that feed the water heater. It is a good idea to check whether the circuit breaker has tripped. If it has, try flipping it up. If it doesn’t work, there is some hitch in the wiring or the switch. Call in an expert.
Sometimes it is not advisable for the water heater to share the same circuit with another appliance. It may cause a blown fuse. If the high temperature cut-off of the heater does not work properly, it will cause a broken circuit and power will not reach the heater. This also is the job of a professional.
A clogged water filter will cause fluctuation in water flow and temperature. It is easy to remove the filter once in a while and clean it under a tap.
A lot of water heater problems can be put down to hard water issues. If your ground water is hard, it can form mineral deposits inside the water heater and render the water heater less efficient. Apart from periodic flushing of your heater, it is better to install a water softener.
Hot water heater leaking
This is another usual problem with the water heaters. But this is much simpler than electrical problems. First of all you have to resolve the source of the leakage. It can be leakage in the condensation valve. Modification in the leaky fittings will cure the problem.
If the water is discharged through the heating element gasket, replacing the part will solve the problem.
If you detect water on the floor of your bathroom or room where the water heater is installed, check for the source of it. If it is a leaky pipe, you can easily remedy it by sealing it off.hot-water-heater-linking
If the leakage is from the tank, you may have to call in a professional to check on it. It is possible that your tank has corroded because of age in which case, it may have to be replaced.
Water heater leaking can be prevented if the fittings used are of the correct size and all the joints are secured with proper washers.
Check which water smells. If it is the cold water, the problem is with your groundwater. Install a water purifier. On the other hand if the hot water smells of rotten egg, it is caused by the sulfur in your groundwater and the anode of your water heater, reacting with each other to produce hydrogen sulfate which is foul smelling. Replace your anode with aluminum or zinc one.
