If you have ran out of hot water, chances are you will need some water heater repair done or if your water heater cannot be repaired, you will need to replace your water heater.
Repairing a Water Heater
Before any water heater repair can begin, the electrical panel needs to be checked to make sure that the circuit breaker is in the “On” position. If any fuses are blown, they will need to be replaced. Once blown fuses are replaced and circuit breaker is in the “On” position, you will have to wait anywhere from 30 to 60 minutes to allow the water to warm up. If the water does not get warm after an hour has elapsed, there is more troubleshooting that can be done in order to found out what is causing the problem.
At this point it is important that the power being supplied to the water heater is shut off. This is because voltages, which can cause shock, burns, and sometimes-even death when in contact with your body, are being supplied to the water heater. Before beginning any water heater repair, either the fuse for the water heater needs to be removed or the circuit breaker needs to now be in the “Off” position. It is important to tag the circuit breaker or place a note on the panel notifying others that work is being performed, in order to prevent any injuries.
The upper access panel and lower, if there is one, will need to be removed. A voltage meter can be used to make sure that there is no power in the wires to the tank. At this time, the water heater should be inspected for any signs of damage, leaks, or rust caused by leaks. If there are any signs of short circuit or water damage to any parts, it is important that those parts be replaced, to prevent even more damage or possible injury.
There is a high temperature limit switch that has a reset button. There is a set of terminals that controls the upper controls and lower controls. The thermostat, which is located below the high temperature limit switch, should be checked to see what the temperature is set at. The heating element is usually attached to the thermostat and the wires connect the two, should be checked.
There is a lot of electrical troubleshooting involved with water heater repair and it is important that if you do not know what you are doing, that you call a professional plumber to check and repair your water heater.
