Cut power off and take off cover to reveil element with number on it's side to give you info to get another one rated the same to go back in.
Make sure power supply is off to water heater and then turn water off to water heater. Then open a faucet's hot side and connect a water hose to drain and drain down water out of water heater to keep from getting water on floor. After heater is drained you are now ready to remove wires and element with a socket 1 3/8 "..

Replace new element in place and turn water back on and fill heater back up with all air out of system before cutting power on. Once air is out and water running from all facuet's hot sides throughout house now you can turn power back on.

One more thing when draining tank if it doesn't want to drain good open lever on relief valve to allow water drain faster.

Our Titan N-120 stopped heating suddenly so they suggested we change the elements. My husband bought 2 elements but apparently he didn't realize 1 is 5000W and the other 5500W. Now could this stil

the bigger wattage elements will heat quicker and consume more power
If they fit , they will work but you may have to check the amperage capacity of the circuit breaker
I imagine you are meant to replace the existing elements which woukd have been half what was purchased

Hello - I have a 6-7 yr old Whirlpool EnergySmart 50 gallon 5500 watt water heater. (Two control boards fried and were replaced free). Symptom now is not enough hot water. No 'error codes' are blinking...

1) Residential water heaters are non-simultaneous. Only one element works at a time.
Upper element comes on until top of tank is heated, and then lower element is switched on until lower part of tank is heated. Lower element keeps tank hot during standby hours

2) Typical Whirlpool energy smart has 4500Watt elements. Look at label on side of tank
If both elements were ON, that would draw 9000Watts or 37.5 amps, requiring 50 amp breaker and 8 gauge wire. V x A = Watts.
All dual-element tanks are 240V.
Whirlpool energy smart requires 10 gauge wire and 30 amp breaker so electronics are not starved during operation. If your wire or breaker are undersized, that is suspect for repeated failure.

3) Typical electric water heater heats 21 gallons per hour. First hour delivery is higher since elements heat water as you use it. Overall however, electric water heater cannot re-heat as fast as gas because gas water heater burner carries more BTU punch per minute than electric element. Gas heats about 41 gallons per minute, with higher first hour delivery.

4) IF YOU HAVE OLDER energy smart and installed newer board, then you could have non-simultaneous operation is reversed so that lower element comes on first.
Read following post at Fixya:
Contact Whirlpool 1-877-817-6750

5) Another potential problem is that you have sediment inside tank and that is reducing efficiency of lower element.

Add a comment with your experience so others with same-similar problem can benefit.

The electric element doesn't work.It has power to the plug in but does not heat. The gas works fine. Where is the heating element on the tank?

It will be on back side of water heater, follow hydro wires into metal or plastic cover. (shut breaker off before proceeding) remove that cover and you will find element. Double check thermostat and ECO for tripped reset switch (little button in center of it) while cover is off as well, before going through trouble of changing element.

New Rheem electric 50 gallon not heating

Check the elements, if you have access to a meter to check them. If they are getting power to elements and you have no hot water.
The elements are not working correctly. I had some elements check out ok till the thermostat's turned on and the elements didn't heat.
Sounds like the elements are bad.

How do i change the element in my water heater

The most important step is to turn the power off. If you still have the manual it is the best to follow the instructions provided in a book.

If not, learn about electric water heaters, how to test the heating elements, how they work and are they OK, than follow the instructions:

Once the power is off, turn the water supply off, attach the hose and drain the water heater.

Unscrew the terminals from the heating element and unbolt the elements from the water heater.

New heating elements has to be with same specs as the old one.

Before turning the water heater on it is VERY IMPORTANT to refill the tank.

I have change the bottom heatern and the bottom thermostat but the bottom heate do not have current even if the top heater and thermostat have current.

There will be no current to bottom element until top element shuts off. then top thermostat will send current to bottom element only after the top half of the water heater has heated up and shuts off current to top element. Only one element at a time can be on. If current still does not go to bottom AFTER top element shuts off, the top stat could be bad.
