Rated voltage squared divided by rated wattage = ohms
Element rated for 240 volts and 3500 watts
240 x 240 = 57600
57600 divided by 3500 = about 16 ohms

SOURCE: new rheem water heater only gives about 5 minutes

Given that both elements are in working order, and the unit was filled before the elements were powered up. Here are a few other areas to troubleshoot.

Note: Electric water heaters contain high voltage, so care and safety must be employed when attempting any service or repair. Do not attempt any service, if you are not secure in your abilities.
Quality non-conductive gloves and eye protection should be worn.

First check that power is being supplied to each thermostat and then to the element when the thermostat is active. Make final temperature adjustments evenly, so as to not over work one element.

Next, check that trapped air is purged from the tank, by placing a catch pan under the TPRV (temperature and pressure relief valve) and quickly engaging it to see if air escapes, if it does then continue until only water is released.

Finally check to be sure that during installation, the cold water feed and the hot water supply lines were installed to their proper locations at top of tank.


Good luck...Let me know the results of your tests.

SOURCE: I had a water heater that stoped heating. I

WHEN THE ELEMENTS R OHM'ED OUT, THEY SHOULD READ "0", INDICATING THERE IS CONTINUITY. ANY OTHER READING IS A FAULTY ELEMENT. U CAN ALSO OHM THE T-STAT 2 SEE IF THAT IS OR ISN'T THE PROBLEM AS WELL.

1) You posted under Rheem-GE electric water heater.
If upper element is burned out, then water heater will not heat any water.

Replacing sensor on whirlpool water heater

Water heaters only have a top and bottom thermostats which seldom go bad. Heating elements wear out most often. If you are running out of hot water too quickly kill the power drain the tank and remove bottom heating element using a special large socket. Visual inspection should tell you if it is melted. If it is ok check the top heating element. If the heater was on and the tank not full the top element will go first. Elements never operate at the same time

We can't get our hot tub to heat. The heater light comes on but the heater still won't heat.

heating elements are resistors that get hot
one end will have 115 volts but the other end should be considerable less because the resistance of the heating element drops the voltage
if you used a ohm meter you should be reading a resistance of 500-1000 ohms for a good heater element but with your readings , there will be no resistance so the element is faulty

I have a 85 gal rheem water heater-one of the heating elements is not working how do i find out which one it is

Get a volt/ohm meter. Turn the power off to the water heater. Take the wire off both elements. Check for continuity using the ohm part of the meter. Put red lead where one wire was and black lead where the other wire was on same element. Meter should move when you attach leads. If the meter does not move that is the element that is bad.

Replaced my Disposal forgot to push the punch out, the dishwasher never had a chance to drain. The heat element no longer works. Does whirlpool Quiet 1 series have a default breaker of reset button?

there is no breaker but there is a thermostat limit under unit where you also have to access the wires to the heater on this unit. may have tripped out this device it will be round small metal, it should not have damaged if water was left in unit i am willing to bet the heater just has failed. if you get to bottom of unit and remove wires to heater test and see if you have contuinity through heater should read through it. if no contuinity then it is bad and will need replaced...

To check the elements hot water hearter stop heating.whirlpool electric

While the power is off to the water heater it's safe to remove the access panels. Once the elements are exposed a multimeter that is set on the Ohms can be used. The average reading of a good element is around 12 ohms. This can range a few ohms up or down. If you don't get a good reading the element will need to be replaced.
If the water heater has two elements the top element should be checked first. When a Whirlpool heater has two elements and the top goes out this will cause the water heater not to heat at all.
If both elements show they are good it would be recommended to contact the manufacturer. The technical support line for the Whirlpool water heaters is 1-877-817-6750.

Whirlpool model # ee3jd40rd045v electric water heater is not working?

First do you have 220 volt power to the heater?
Second do you have 220 volt power to both elements?
Third do a ohm test on both elements with the wires disconnected
if it shows OL then your element is blown
Forth if you have power to only one element then your control is bad.
Good Luck

The heat control valve appears to have stuck, the water is only luke warm

I do not know what heat control valve you are referring to on an electric water heater. On an electric water heater it has two heating elements in most cases. One at the top and one on the bottom. One of these is more than likely defective. Turn the power to the water heater off at the service panel or at a disconnect switch. Now take the covers off both heating elements. Check each one with a ohm meter to see if you have continuity. If your meter reads nothing that heating element is bad and needs replacing. On each heating element is a thermostat to set the temperature. Set the upper element to 120 degrees and the lower element to 130 degrees.

We just bought a new water heater and it's not heating up water.

The heating element was bad. It's hard to believe that a brand new water heater would have a burn element, but that's the problem. I replace the heating element and its started working properly.

I need to know exactly how to hook the wires up to the elements

Have you checked that you have the proper voltage to the unit? You can do an ohms check and it should read 5 to 10 ohms on the elements. If this reading is good then the elements are good. Putting in new thermostats should have been sufficient. You need to start at he breaker box and start there checking voltages then work your way to the water heater. Somewhere you are not getting power to the unit. Both elements and both thermostats can't be bad at he same time. Too much of a coincidence.

Limited hot water

Some checks are surely possible but PLEASE make sure that the 220VAC is absolutely shut down.
In a home we built in 1977, circuit breakers were improperly marked and I, with decades of experience, believed I had turned off the power to our water heater only to find that it was still 'hot' and blew away a screwdriver tip before thinking to check across terminals to see if the voltage was in fact OFF.
You may have the same problem I had twice over ~30 years; that the lower heating element is open/failed. These typically will gather a coating of mineral deposits and eventually be unable to transfer their heat to water fast enough to avoid overheating and failing.
The limited hot water comes from the fact that the thermostat is checking for temperature at the exit point of the heater; the top. The thermostat turns on both elements but with only the top one still working it heats 10-15% of the tank capacity and then shuts off.
With your meter set to the lowest Ohms scale (typically 200 Ohms), measure across the element terminals. You should measure pretty much a short since the elements have an extremely low resistance; on the order of 10-20 ohms, if you measure anything that goes 'off-scale' on the 200 ohm range (normally blinking), the element is shot.
Don't forget to drain the tank before pulling out the element!      
If you are in the US, near any city, check your white pages for: Johnstone Supply or check their website to see if one is near you.You will pay 1/3-1/2 hardware store prices for the replacement element - buy two, store the second one. They are 'wholesale' to the trade but have never been refused.
If you don't feel like wading through their extensive website, you can take the element with you and they can give you what you need.
