An issue with adequate hot water could be related to the size of your electric water heater and not a maintenance problem. If your household demand for hot water is higher than 75% of the volume of your electric water heater, you may find yourself running out of hot water on a regular basis.

Problems with electric water heaters that produce little or no heat usually are caused by a failed heating element, an inexpensive part that is relatively easy to replace. Other problems may be due to improper settings, high home water pressure, or a lack of tank maintenance. Watch Now: How to Repair an Electric Water Heater

Look at the color of the water coming out of your faucets. If it is discolored, it is possible that there is a build up of sediment in the water heater that is preventing the water from getting hot. Drain the tank completely and flush it out with clean water to alleviate the problem.

A loss of water pressure causes water throughout your home to act oddly. For your water heater, the TPR valve may open and begin to release excess pressure if there’s too much water pressure in your lines leading to the tank. In extreme cases, this can cause your water heater to begin leaking as it seeks to regulate the pressure inside.

An electric water heater works essentially the same way as a gas water heater.It brings cold water in through the dip tube (1) and heats it using the electric heating elements (2) inside of the tank. The hot water rises in the tank and is moved throughout the home through the heat-out pipe (3).

If there's water in the drain tray or floor around your heater, with no apparent leak, it is likely that your temperature and pressure (T&P) relief valve is faulty and leaking water. These valves are designed to open and release high pressure above 150 psi for safety reasons and if the water temperature exceeds 210 F.
