Condensation on electric water heater

I changed both elements on my electric water heater as the bottom one was defective so now it is back to normal and I have hot water.
But I now have also condensation which I do not have before for sure. I removed the element access covers and they are wet inside and there is rust on them now.
The condensation seems to be between the covers and the fiberglass. If I do not put back the 2 element access covers then I do not notice condensation.

Any ideas about what it could be?

Thanks in advance.

Did you put the gaskets in with the elements, there should be a rubber gasket on both elements, if you did and it is just the tank condensating, when you took out the element was it easy or did you have to apply alot of pressure, if you had to apply alot of pressure you may have even cracked the tank, and it is not condensation but water comming out of the tank,, and if you are sure that you didn't then your water comming in must be real cold and you will have to wait for the water in the tank to heat up to stop the condensation,, cold water comming in comes from the bottom thru a dip tube that takes the cold water to the bottom of the tank and force the hot water out the top, if you are on well water it will be vary cold comming in,, these are the only things it could be,, by the way did you fill the tank with water till it came out of the faucet at full pressure before turning on the electric? if not you could have also burnt up both elements and the water can be seeping out of the elements beings they are plastic and when they are fried the plastic melts, so turn off the electric pull out the element check it to make sure it is intact then if not get another new one reinstall it, fill with water till it comes out of the hot side on your faucet, then turn on the electric

Water Heater Issues


An electric water heater contains two elements (usually upper and lower). Normally hot water is maintained at a certain temperature to assure an immediate supply. When hot water is turned on at the fixture, the second element is turned on to boost the temperature. From your description one of the heating elements may be defective or set to incorrect temperature.

MY Rheem 81SV40D Water Heater (47 gal) does not heat enough water. Approximately one bath worth.


You have dual-element 240Volt electric water heater.
Since you have some hot water, then we know upper element is good, and that circuit breaker and electricity to water heater are good.
Not enough hot water is probably bad lower element, and possibly sediment build-up in bottom of tank.
Test element:

Replace 4500 watt element available at local hardware, and clean out bottom of tank:

Rheem electric water heater 50 gallon, lukewarm water. Water is warm but not hot, where should we look for problem?


Luke warm water is the result of top element bad and the bottom is the only one heater. The best solution I can reccomend is to change both out due to the fact the bottom element may go bad and since you have to change one you might as well change both.

Turn power and water off, drain heater down and once water is drained out change them out. Once new ones installed turn water on to fill heater and open faucets and get air out on the hot side of each faucet once water is flowing out of each faucet you are now ready to turn power back on.

I awoke to no hot water, my heater is three yrs old and i just changed my upper and lower element and upper thermostat, still no hot water then i checked to see if i was getting power and i am, is there...


Your water heater has 2 elements so its 240Volts.

1) If breaker is delivering power on one leg of the 240Volt circuit, then water heater can appear to have electricity, but tank is receiving 120V. Both 120Volt legs are needed to complete the 240V circuit. Double check for 240Volts.

2) Review electric Load.
Water heater label shows wattage of tank.
If tank is 4500Watts for example, you installed 3500 or 4500 watt elements.
With 5500 Watt elements you need 30 amp breaker and orange-colored 10 gauge wire
With 4500 Watt elements you can get by on 20 amp breaker and 12 gauge wire up to 75 feet away.

3) Check ECO red reset button on upper thermostat. If reset is tripped, then ECO is reading high temperatures. Suspects at this point are defective upper thermostat, shorted wire or bad lower element.

4) Also note that insulation and cover must be re-installed over thermostat. Thermostat reads temperature through wall of tank. If outside air circulates around thermostat, that can cause a mis-read and cause tank to overheat and ECO trips.

If you don't want to test the heater, replace both thermostats for about $25. Return the upper thermostat for a refund. Then see of problem persists.

Here's what I would do.
1. Check breaker for 240
2. Check water heater for 240 across 1 and 3 screws on upper thermostat
3. Note wiring and breaker size.
4. Note label on side of tank.

5. Look at end of new element to see wattage printed on each element. Look for sings of high heat and burning. Tighten screws on elements.

6. Check ECO reset button. Look for high-heat and burning. Tighten screws on thermostat.

7. Test upper thermostat as follows:
http://waterheatertimer.org/images/Electric-diagram-water-800.jpg
Test left-side #1 screw to right-side middle #4 screw. Test should read 240V at all times. If not, then ECO is tripped, thermostat is bad, or electricity is OFF

8) Water heater is cold so upper element should be ON. Test upper thermostat.
Test right-side #3 screw to left-side bottom #2 screw and it should read 240V
Test right-side #3 screw to right-side bottom #4 screw and it should read 0 volts

8. If upper thermostat checks out. Test upper element for 240 across both screws. If upper element does not read 240 when water is cold, then element is bad or there is a shorted wire between element and upper thermostat.

The controls of electric water heaters are designed so that at no time are both the top and bottom heating elements energized. Nearly all electric water heaters of this capacity in the US & Canada (other places, too) operate on 240 Volts.

When the water in the tank is below the set point of the thermostat (in your case - 120 degrees), the top heating element is expected to be on - (unless there is an issue with the top thermostat or limit switch). The top most control is the "high temperature limit". It is identified by the reset button on it. Make sure this isn't tripped by depressing the button. If it clicks - it was tripped and should start to make hot water at this point. If not tripped, you should check for the presence of 240 Volts between the heating element terminal screws. Do not measure from ground to a terminal screw and believe 120 Volts is "good". To make heat, you need 240 Volts - not 120 Volts measured across the terminals - not to ground. The amount of heat created running at 120 Volts is only 1/4 of what it will do at the correct voltage.

If you don't measure 240 Volts on the top element, check the bottom element in the same manner described for the top element.

If unable to measure 240 volts on any element, either there is a problem with the power source (blown fuse or circuit breaker), high temp limit switch, or thermostat(s).

If 240 Volts is present on either heating element, and water is not warm / hot in 30 minutes or so, a defective heating element is suspect. You can change controls without draining a tank, but replacing elements will require draining the tank first. Do not power the water heater without first filling it.

You can read a very detailed "how to" article about checking water heaters here.

I hope this helps - and good luck!

Lower element will always test 120V to ground since thermostats turn off one hot wire.

Listed below are suspects in order of ease.

1) Check that hot water is not running out of TP valve and down into a drain.
This will cause water heater to run all the time but not be able to keep up.

2) Test elements before replacing anything:

3) Test electricity to water heater:
http://waterheatertimer.org/Test-electricity-to-water-heater.html

4) Replace both thermostats.

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.

Tank no getting hot enogh


It sounds like the lower element is defective from the factory. There is an 800 number on the heater, and they will ask for a serial number. The temp range on the heating elements will not affect the performance of the water heater, as it is filled from the bottom
