make sure it is wired correctly, check circuit breaker, check breaker built on to element. If all fails, and it is determined your not getting power to it, you may need a electrician. Be careful. good luck.

the hot water tank may be filled with scale buildup on the inside. drain a few gallons out of tank until the water runs clear. it is best to drain out water heater at least 2 times a year.

Possible thermostat problem. Are you experienced enough in that area to do some testing. Have a multimeter? If not experienced, don't try it, too dangerous. Call in a service person.

The elements may be burnt out you can check them by an electrical light tester. There is a lower and an upper element. If the tester lights up element is good. I hope this helps, please rate if the answer was helpful. Have a great day. Jeff

You should have two panels on the front of your water heater most likely painted blue. Each of these panels contains a heating element. The top panel contains the reset switch. Unscrew and remove the top panel and you'll see the reset switch - it is the red button. Press it to see if it clicks. If so, your hot water should last longer.
If it does not last longer than you stated, then you most likely have a bad heating element. The problem is that unless you remove both elements, you won't know which one is bad. If you don't feel comfortable turning off the water valve to the heater, turning off the power to your water heater at the circuit breaker box, draining the heater of it's water using a garden hose, removing the wires from the elements, removing the elements and installing new ones from your home improvement store then you may want to hire a plumber to do it.
The process is fairly easy but time consuming. The most time is draining the water heater. If you do choose to do it yourself, you will need to get a special "wrench" from your home improvement store to remove the heating elements first. The store can help you with the element(s) you need once you take them in.
