What happens when the bottom of a water heater fails?
This is a sign that the bottom element has failed. If the upper unit is still working, water at the top of the heater will heat. You’ll get a little bit of hot water before the supply runs out.
Why does my hot water heater change between hot and cold?
If your hot water temperature changes between hot and cold unpredictably, you may need to test the lower hot water heater element. On home water heaters, there is an upper and lower thermostat, and the upper one diverts power to the lower one when the water at the top of the tank reaches the correct temperature.
What causes an element in a water heater to burn out?
Heating elements can burn out. Sometimes one element fails causing the other element to work overtime. A burnt-out element is a common cause of water heater woes.
What should I do if my water heater is not heating properly?
To drain the tank, shut off the inlet water valve, attach a hose to the drain valve, open the drain valve and hot water faucet and wait until the water is lower than the heater element. Remove the element with a socket or element wrench, and ensure that the new gasket is secure in place as you tighten the new element.

What happens when an element overheats in water?
When the elements get coated, or when the lower element is buried under mineral sediment, it has to work harder to heat the water. Sometimes, the element overheats and the water absorbs this heat. The element typically fails and burns out not long after overheating.
