Question about Water Heaters

1 Answer

I have a rheem electric 40 gal tank that keeps burning out the heater elements was every 3 months now every other weekend. We have tried both stainless steel rods and copper neither are lasting. I just installed a copper one today but don't have high hopes that it will see next weekend alive. Everyone is saying it's the other fault. Water people say it's heater-- Rheem says it water. HELP! i've shelled out over 80 bucks now for heater elements... My sister is ready to sell house and I need answers now!

Sounds to me as if you have an electrical problem, such as low voltage that is creating an over amperage and burning up the elements.Consult an electrician

I have a rheem 40 gal electric water heater. The GFI on the tank keeps popping do you know what could be causing this


10-23-12
Your tank has a GFCI circuit breaker?
Maybe you mean ECO reset button located on upper thermostat?

If GFCI circuit breaker is tripping, turn power off, open covers inspect for burned parts, and test elements. Copy following link for troubleshoot walk-thru:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#trip-breaker

If ECO reset button is tripping, then replace both thermostats, and test elements.

Rheem 49 gal model 81V400B - hot water lasting only 5-10 minutes then takes an hour to heat back up.


Ordinary tank-type electric water heaters are fully repairable by homeowner.

A) Basic info on Rheem
Rheem electric water heater website:
http://www.rheem.com/products/tank_water_heaters/electric_water_heaters/
Find age of Rheem: look 2nd and 3rd digit of serial number, for example 06 is 2006

B) Water heater has some hot water.
That says certain things: upper element is working, water heater electricity is working, reset button is not tripped, and heater is not experiencing run-away overheating event.
http://waterheatertimer.org/How-it-works.html

C) That leaves 4 suspects that cause lower amount of hot water.

1) TP valve is running hot water out of tank -or- leaking faucet is running hot water out of tank.
Check for leaks
http://waterheatertimer.org/How-to-replace-TP-valve.html

2) Lower element is burned out.
Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

2) Upper or lower thermostat is bad.
Replace both thermostats for about $25.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

3) Burned or shorted wire located between upper and lower sections of tank.
Turn off power. Open covers on side of tank. Remove insulation. Inspect parts for signs of high heat and burning. Especially check lower element. Tighten any loose wires. Replace part that shows signs of burning.
Put insulation and cover back over thermostats so cooler outside temperature doesn't cause thermostat to misread tank temperature.

Not getting enough hot water


You posted under Rheem 40 gallon tank-type electric water heater.

You have some hot water so that says specific things:
-Upper element is working.
-Electricity to water heater and circuit breaker are good
-You don't report a leak so TP valve is good
-You are not experiencing overheating event
-ECO reset button is not tripped
-Insulation and covers are in place so thermostat not exposed to cooler temperatures that would cause thermostat to misread temperature and cause overheating.

That leaves 6 suspects listed in order of difficulty:
1) Leaking faucet or broken water line that is running hot water all the time and tank cannot keep up.

2) Thermostats set too low. Turn power OFF, open covers and check each thermostat.
http://waterheatertimer.org/How-to-adjust-temperature-on-water-heater.html

3) Loose screw, loose wire at upper thermostat, lower thermostat, or lower element. Turn power OFF and tighten screws, and look for signs of high heat and burning, especially on lower element.

4) Upper or lower thermostat. Replace both thermostats for $28 and see if that corrects problem.
Parts available at home center, hardware, or plumbing supply
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

5) Defective wire between upper and lower sections of tank: If this is the case, and water heater has 2" foam insulation, then tank usually replaced since insulation is too dense to drop another wire. Call for manufacturer for warranty information. Do a full troubleshoot using multimeter.
http://waterheatertimer.org/Water-heater-manufacturers.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

6) Lower element is burned out. Test lower element. Replace lower element. Rheem elements are 4500 Watts and are available at home center, hardware, or plumbing supply

Hello, i need to know how to change the lower element in my rheem 40 gal. water heater


Rheem uses a 4-bolt 4500 Watt element available at hardware store and some home centers:
To confirm wattage, see label on side of tank. Also note you label shows gallons, and show a serial number that has date of manufacture in fist 4 digits, for example 0605.. is June 2005.

The element is removed using a wrench. Remove 4 bolts. If bolts are stuck, then use WD40 and ratchet with extension. You can also drill out the bolt and re-tap holes with new thread. Don't drill through wall of tank which is about 1/4" thick.

For generic step by step for replacing water heater element and cleaning out tank:
http://waterheatertimer.org/How-to-replace-water-heater-element.html
Link shows how to drain tank, check if electricity is off, and general sequence of steps.
Rheem element that you buy comes in package with specific step by step for replacing that element. Be sure to clean opening of any debris before installing new element.

I am only receiving half of the normal amount of hot water.


You have electric water heater.
Electric water heaters are fully repairable by homeowner, excluding hybrid type.

Rheem electric water heaters:
http://www.rheem.com/products/tank_water_heaters/electric_water_heaters/
Rheem fury series manuals and models
http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619

Age of Rheem water heater is shown first 4 digits of serial number located on side of tank: for example 0705 means July 2005.
Serial number also shows model number & wattage of elements in case you need to buy new generic 4-bolt type 4500 Watt element from hardware store.

A) If your water heater receives very cold incoming water, it may not heat fast enough to keep tank warm.
Add a tempering tank.
http://waterheatertimer.org/Tempering-tank.html
Add insulation over entire water heater except TP valve. Insulate pipes completely.
Read more information:
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html

B) 40 or 50 gallon water heater is 240Volts and tank will have 2 access panels on front.
Rheem ships all water heaters with 4500 Watt elements.

Narrow down the suspects:
C) Water heater has some hot water.
This tells us upper element is working.
And that water heater electricity is working.
And that reset button is not tripped.
And that heater is not experiencing run-away overheating event.

That gives us 3 solid suspects.
1) lower element is burned out. Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:
This will restore water heater to full 99% efficiency.
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

2) Upper or lower thermostat is bad. Replace both thermostats for about $25.

If you want to test thermostats and all parts before replacing anything:

3) Burned or shorted wire. Turn off power. Open covers on side of tank. Remove insulation. Inspect parts for signs of high heat and burning. Especially lower element. Tighten any loose wires. Replace part that shows signs of burning.

My water is not heating in my Rheem 40 gallon electric. I pushed the reset button, but when I turn off the breaker and then on again, I do not hear the elements heating up.


Electric water heater can be repaired by homeowner
If I understand correctly, water heater is producing no hot water.
Reset button clicks in, but still no heat.

Three initial things can be causing this:
1) No power to water heater. Test across top two screws on upper thermostat for 240V. Red and black wire are attached to these screws. Screws are marked 1 and 3. Upper thermostat is same that has reset button. If power tests 120 across screws, then breaker may be off on one leg. If no power, then start testing at breaker.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

2) Upper thermostat is bad. Replace thermostat with generic upper thermostat available at hardware store.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

3) Upper element is bad. Test and replace element using Rheem 4500 watt element available at hardware store. Image shown below. Look at label on side of tank for element wattage. Rheem puts 4500 watt elements into all their 240V electric water heaters.
http://waterheatertimer.org/How-to-test-water-heater-element.html

If upper element is burned out the tank will not heat any water.

Water is not hot, doesn't last long. Thermostats turn elements on when turned up. Elements show 230 when on.


Lower element can be burned out and still read 230V across screws

1) We know thermostats are working because elements test 230V.
2) We know upper element is working because tank has some hot water.
If upper element is burned out, tank will have no hot water.
http://waterheatertimer.org/How-it-works.html

3) Here's how to test lower element:
http://waterheatertimer.org/How-to-test-water-heater-element.html

4)Here's how to replace element
Rheem element is 4500Watt bolt-in type
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

5) Rheem manual says: Heaters furnished with standard 240 volt AC, single phase non-simultaneous wiring, and 4500 watt upper and lower heating elements.
