It sounds like the element is burned out and needs to be replaced.

To do this the water supply to the tank needs to be turned off, as well as the power supply (Breakers) and the tank drained.

As a preventative measure replace them both while the tank in empty.

Note: do not power the unit until it is full of water and the tank is purged of all trapped air.

Good luck...

We just installed a hot water heater that's


1) Test elements, and if elements are good, then replace both thermostats.
Takes about 20 minutes. Power is off.

http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

2) Label on side of water heater shows volts and watts.
For 4500 watt elements, you need 30 amp breaker and 10 gauge wire.
Move water heater wires to different same-size breaker.

3) Open the links and do the work, or call plumber to do work, or call manufacturer for warranty coverage.
If your wire and breaker are problematic, then service is not free.

Newly installed Hott Rod in 6 gal RV water heater only heats to lukewarm. Has been on for 12 hours. Outside temperature is 60 degrees


Hott rod is 120Volt AC.
Check voltage supply for undervoltage, or reversed polarity, or tripped breaker.
Check that electric thermostat is set to 120 degrees.
Rotate thermostat temperature adjustment back and forth and see if you can hear water heater working.
Thermostats can be bad, or stick.
Check the ECO red reset button is not tripped out.
If tank was not full of water before power was applied, the element will instantly burn out.
Use continuity tester across bare element screws to see if element is good. Or use multimeter and test across bare element screws shows 29 ohm for 6 gallon, 18 ohms for 10 gallon.
More resources at Hott Rod, for troubleshoot and contact.

Hi...I have a Whirlpool water heater and the water only stays hot for a few minutes. How do I adjust the temperature or settings so that I can have hot water all the way through the shower instead of...


I am guessing this is an ele water heater and the temp setting are not the problem.
Problem: Not enough hot water or water temperature too low. When the top of the tank is hot the upper thermostat removes power from the upper heating element and transfers the power to the lower thermostat and heating element. If the lower thermostat is defective, then the lower portion of the tank will not be heated and the supply will be greatly reduced.
Check for power at the upper thermostat terminals where the power is sent to the lower thermostat and heating element. If there is no power then the upper thermostat should be replaced. If there is power then check for power at the lower heating element. If there is no power at the lower heating element then replace the lower thermostat.
If there is power to the lower heating element then it should be getting hot. If it is not, replace it. Another possibility is a broken dip tube. Check for a broken dip tube and replace if necessary.

The dip tub is located under the fitting where the hot water comes out.

You can open the top up again. I would not turn the temp higher than 130 degrees, maximum. However, there should be above the thermostat a red button. This is where the power wires connect to the thermostats and heating elements. Sometimes this button needs to be reset, press it and discern if you hear a click sound. This means that the high temperature safety switch has tripped open and you had to manually "reset" it. There are two thermostats by the way. The water heater usually works this way. There are two thermostats and two heaters. The upper tank heater turns on first and it heats the top half of the tank. Then when the thermostat above is satisfied it then allows the bottom heater to come on and heat the bottom half of the tank. You might want to set the bottom heater thermostat as well. This is made this way because it is actually faster and more efficient to heat the top half first and the bottom half secondly. Try this first with the reset button. We could check voltages, but that requires a level of knowledge and safety that I am not sure that you are comfortable with. Pictures of the upper and lower thermostats and connections will help if the "reset" does not do the trick. By the way, not meaning or implying anything, but did you move the thermostat in the right direction? Sometimes the dials can be confusing.

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.

Electric hot water heater gives lukewarm water


replace upper thermostat and hi limit switch. These are usualy made in one piece. On a two element heater, only one element comes on at a time

Water is lukewarm. Not hot! Two year old tank, 220 amp is present. Both sides of relay have 220.


Make sure you have power going to elements from thermostats. check lines going to elements.

Luke warm water is the result of an element gone bad most of the time. One at th etop gone will cause you to get just luke warm water and one at the bottom gone will give you real hot and then cold.


The elements are not to exspensive so if it has two you might as well replace both of them. If you just put 1 new one in it will work the old one till it goes.

Cut power off and cut water off to water heater and drain heater, open hot side on any faucet to help it drain. once drained remove element they have a tube type socket at hardware stores for the removal of it.

Put elements in and fill water heater till all air is out of lines before turning power back on. make sure water is flowing out of all faucets before turning power onto water heater.

The reason being is the elements has to be in water not open air in tank or it will blow new ones.

Water is no longer hot


A heating element is either good or bad and no inbetween. If your unit has two elements, then one of the elements is bad. If it is a single element unit then the thermostat has gone bad. Do a voltage check to see if you have power going to both elements and if you do then do a ohms test on the elements. They shoudl read 5 to 10 ohms. If one of them doens't, then you know it is bad. If by chance check the elements and everything is working, the only thing that can be left is that the dip tub has ruptured somewhere close to the top of the outlet. But I would put my money on a bad element.
