Why does my water heater have a thermostat?

Water that gets into the compartment for any reason may also cause the thermostat to short out. In the case of a damaged thermostat, you will need to replace it.
Why is my water cold?
Perhaps the most common reason for water to remain cold in a busy home is an empty tank. Water heaters work hard to heat an amount of water which fills the tank , but this tank has a limited capacity.
How to tell if a tank is fully drained?
Every few minutes, pause the draining process and fill a bucket. Let this sit for a few minutes and examine the bottom for any signs of sediment. Clear, sediment-free water means you may stop the process completely. Conversely, cloudy water or visible sediment on the bottom of the bucket means the tank is not yet fully flushed.

Unmanageable Hot Water Demand
One of the more common issues that can impact the temperature of the water is the current demand within the household.
Sediment Build-Up
Homeowners that regularly deal with hard water problems are likely familiar with sediment build-up in the bottom of the hot water tank. Over time, minerals in the water sink to the bottom of the tank and stick to the heating elements, reducing the amount of heat transferred from the heating elements to the water.
Leaking Hot Water Tank
A leak from the hot water heater needs to be fixed as soon as possible. Not only can a leak reduce the temperature of the water, but it can also cause severe injury to unsuspecting individuals who may step in or touch the leaking hot water.
Damaged or Displaced Dip Tube
