There is a possibility that the heating element is now burned up, you can refill the tank and try to heat water,, if the water is not getting hot then I would say that you need to replace the element. also check the circuit breaker and wall outlet for power just incase the element did blow the fuse.

Electric water heater stopped working


The unit doesn't like to drain without air coming in on top of water, so flushing with pressure applied is the preferred way. Be careful, see if you have power coming into unit. Turn off power and open the connection connection plate I would suspect that if the breaker is supplying power, sometime I have found that the connections are not properly made.. . If you a timer to limit operational hours take it out and go directly to romex from breaker panel.I f water starts hot and then go cool very quickly the bottom heating element and or thermostat is not working. Remove lower element cover and with power off check element resistance you can compare upper and lower element readings. From experience I never repair water heaters: time and material is more than new unit. You will need to buy element socket heating element(s) and or thermostat(s). In the end you still and old water heater.

Over heats and shuts off


The top thermostat controls your water heater meaning if it is not working you wont have any hot water. If the top t-stat needs to be reset by pushing button in then check the element with POWER OFF and remove wires from element. check ohms should be around 12 to 19 ohms. If ok then reconnect wires and check amps. turn on power and use clamp on meter for amps. 15 to 20 amps should be ok. if not drain heater and pull out element. while you are at it drain all the water and pull lower element. if replaced and you have some hot water then quickly cool or cold then you have a broken dip tube located under the cold side of the supply line. they are cheap and easy to replace. I hope this helps.

Hot water recover time


No.
Fold-back elements are low-watt-density, so element does not burn out as easily since heating is spread across more surface area. But recovery remains 16 gallon per hour.
20 amp breaker and 12 gauge wire: max 3800 watts
30 amp breaker and 10 gauge wire: max 5800 watt.
4500 watt element heats 20 gallons per hour.

Instead of changing elements: Set thermostats higher so more cold is added to hot water, and then you have more hot water available inside tank.

How to replace water heater element will water cme out when you remove element does tank have to be drained


Safest method:
Shut off electricity to heater.
Shut the water valve.
Drain heater to below the level of the element, open hot water valve in house to vent heater to speed draining.
If the element is on top, you don't have to empty the heater.
Remove old element, install new element.
Leave hot water valve open somewhere in the house.
Turn water on.
Once air is removed at hot water valve, turn electric on.
Shut water valve.

What cause the water heater to take more than an hour to heated up and unable to last longer. Usually its take about 15 min. to heat up and can last longer.


'Rheem 81VP15S point of use' is a single-element, 15 gallon, 120V electric.
Other 'point-of-use' sizes range from 2-1/2 to 6 gallon to 20 gallon.

Electric water heaters have 2 parts: thermostat and element. One is not functioning correctly. Most likely the element caused by sediment build-up.

How to determine if tank has element or thermostat problem:
Do not turn off water going into tank. Put hose on drain valve. Open drain valve. Does water come out like open spigot? If water does not flow, then heater is likely clogged with sediment.

Solution 1: If water flows out like a spigot, the thermostat is probably bad. Read: How to replace thermostat.

Solution 2: Water does not flow, so element is surrounded by sediment build-up and cannot heat water. You need to clean out tank with shop vac, and put in new element ... plan full day and 3 trips to hardware store. Simply draining tank will not remove sediment. Sediment is chunky and will not come out voluntarily.

Buy element before starting:
-Turn off electricity
-Open cover on side of tank, remove insulation (these have to be put back for proper operation of thermostat)
-The are 2 electrical parts >>the element and the thermostat which is located above element
-Element wattage is printed on element and also shows on label on side of tank
-I think Rheem element is held in place with 4 hex bolts
-Take photo of element to hardware store so you have part on hand before removing old element
-If element is 1-1/2' diameter hex type, you need inexpensive element wrench from hardware store + the element

Drain tank and clean sediment:
-Read: To open drain on water heater so water comes out
-Read: How to clean sediment out of water heater

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 own a Bradford White Corp. Electric Hot Water Heater. It has two thermostats, one upper and one lower. Model # M-1-40S6DS 13, ser# XK0300351. My problem is the red button on the upper control trips...


Hello. If you turn off the power and drain the tank then examine each of the heating elements you will find that the upper element is deteriorated. The fix is to replace the heating element. Actually though my practice is when one is bad the other isn't far behind so for a few dollars I change both when I have the tank drained. Joe

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.

Whirlpool temp control on electric water tank


Most electric water heaters have 2 heaters - an upper and a lower, each with it's own thermostat. These are readily accessible by removing the screw covers on the side of the tank. Careful - the thermostats have 240VAC on the terminal screws (unless you have a small 120VAC heater) if the circuit breaker or fuses feeding the heater are still on - turn them off before proceeding. After removing the two screw covers and pulling back the insulation you will see temperature (screw) adjustments for the upper and lower thermostats, with a temperature indicating pointer attached to each screw. Set both thermostats to 125 degrees or so. Push the insulation back in place, replace the covers and turn the circuit breaker back on that feeds the water heater. You should have warm water within 15 minutes and hot water within a hour or so.

If the water still does not heat, then you have to troubleshoot to find the problem. With a voltmeter determine if 240VAC is actually getting to the water heater. Remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.
