SOURCE: I tried to drain my electric water heater. After

The "sacrificial rod" is actually there to prevent the heating elements from being eaten away. by electrolysis. If the deposits in the bottom of the tank are simply from sediment from your water, the tank may be fine. You won't know though until you get the tank drained and inspect the elements. The drain valve screws in just like any other piece of pipe if that helps you get it drained, or a piece of wire through the valve may work but you might damage the rubber washer in the valve. Once drained, and the element removed, inspect the element. There should not be any fissures in the element if you have an otherwise healthy tank. visible blowout usually means the rod has failed.
The presence of heavy deposits indicates hard water, which results in shortened tank life.

SOURCE: Our electric water heater doesn't work.

make sure it is wired correctly, check circuit breaker, check breaker built on to element. If all fails, and it is determined your not getting power to it, you may need a electrician. Be careful. good luck.

SOURCE: TRYING TO REPLACE MY OLD RHEEM WATER HEATER MODEL

I would say your water heater is from the fury series; new model number 82V52-2. I've included a link with my solution that you should take a look at. You could also look at water heaters of a different brand if this one isn't available in your area. Kenmore, GE, and Hotpoint are all very good brands of water heaters.

I cannot find your model number
The serial number seems to show it was made in 1994, so the spec sheet would be difficult to find
You must have bought a good heater and taken care of it for it to last that long.

Typical 40 gallon Reliance electric:
18" x 59-1/2"

Self-cleaning type Reliance 40 gallon

The size of your heater can be determined by measuring the height, and then measure across the top to get the diameter. Your measurements will be close to the numbers shown above.

HOW LONG DOES IT TAKE AFTER INSTULATION TO HEAT WATER


Electric water heater typically makes 21 gallons hot water per hour.
Gas heater makes 41 gallons per hour.
If you use a timer on electric heater, it will make enough hot water for shower in about 15 minutes summertimer and 30 minutes wintertime. So incoming water temperature is a factor.

If your water heater is not full of water before turning on electricity, then elements will burn out.
Also the ECO might be tripped out: open top cover and push in red reset button.

I have a 40 gallon rheem water heater for a mobil home that is leaking from the top.


If water heater is leaking, then open following 2 links to avoid tank rupture and troubleshoot leak:
http://waterheatertimer.org/Emergency-steps-for-leaking-water-heater.html
http://waterheatertimer.org/Water-heater-is-leaking.html

Open following link if you want to install your own gas water heater:
http://waterheatertimer.org/How-to-install-gas-water-heater.html

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

Our water heater is doing the same thing. . Before I replaced the board I checked the elements, both were about 13.5 ohms, after checking I made sure to replace all insulation and closed the access covers...


1) You have given good diagnostic information ... except brand and model number of water heater are missing.
Locate this information on label on side of tank.

2) 2 flashes for high temperature indicate you have Whirlpool or Craftmaster Energy Smart.
You have dual element 240V tank-type electric water heater with electronic control board and temperatures sensors.
Sensors can be ordered separately for $30 each.
Sensors seem like best suspect since elements test out and you have new control board.

3) Did you test elements for short to ground through center of element?
http://waterheatertimer.org/How-to-test-water-heater-element.html

4) Energy smart requires 10 gauge wire and 30 amp breaker. If wire or breaker are undersized, then I would expect chronic problems with electronics. I believe the requirement is so element draw or other factors don't starve electronic control board.

5) How it works: Energy smart is non-simultaneous water heater. Non-simultaneous means upper element turns on first. When upper temperature sensor is satisfied, control board cuts power to upper element and sends power to lower temperature sensor and element. So both elements are never ON at same time. Lower element runs until lower temperature sensor is satisfied. I do not know decision tree for how microchip processes the information.

6) I have examined this water heater and read the manual. I wrote following page, but have not conducted electrical testing on unit simply because it is controlled by micro-chip.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

7) Sample Energy Smart manual:
Manual does not show how to test temperature sensors, but manufacturer might have more information. Manufacturer might have information how changing meter can affect their electronics.
I would guess undersized wiring would have greater impact than electricity turning off for 1 minute.
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf
Whirlpool 1-877-817-6750

8) 4500 Watt elements should test 12.3 ohms, so your elements check out fine.
Be sure to test for short to ground by setting multimeter to ohms, remove wires from element, and test each screw to bare metal part of heater and to metal base of element.
http://waterheatertimer.org/images/ohm-reading-for-emements.jpg
http://waterheatertimer.org/How-to-test-water-heater-element.html

9) The water heater industry changes very fast, so current manual is best place to start troubleshooting.
If you have different brand than shown above, then open following link to identify manufacturer's website:

Energy smart hot water heater not giving ample amount of hot water both elements ohm at 12.5


element-connection-450.jpg
For images and product information
For manual


You checked ohms, did you check for 240V across lower element when lower element is turned on?

Energy smart electric water heater
has a control box on top of unit. Water heater does not have typical thermostats that can be tested and replaced. Temperature sensors located above each element send information to control box through small black and red wires. Temperature sensor sells for about $40, but there is no test listed that shows how to determine when sensors fail.

Potential problems:
-Temperature sensor is not reading correct temp
-Control box not processing correct temperature information
-Selector on control box set to 2, 3 or 4
-Thermostat temp on control box set lower than 120 degrees F
-Sediment build-up starting to surround lower element so water doesn't circulate (see if drain valve runs full-open
