Check the breaker and top thermostat and make sure they are not tripped. Move onto replacing elements if above is not the problem.
Turn water and power off to heater and attach a water hose to bottom of heater to drain down tank. May have to open hot side on a facuet to get it to drain.
Once drained remove elements with 1 1/2" found at local hardware stores. once elements removed and new ones in place. Turn water on and get the air out of the system. Once water is flowing from the hot side from all of facuet's in house.
Once all air is out now yaou are resady to turn power onto heater.

SOURCE: my husband replaced both elements on our water

The tank has to be completely full of water before turning on electricity or elements will instantly burn out:
http://waterheatertimer.org/How-it-works.html

I would take 40 minutes and do complete troubleshoot before replacing anything else.
This requires $5 multimeter from home center.
Put battery in multimeter.
When testing voltage, rotate multimeter dial to 240-250-277VAC
When testing continuity and elements, rotate multimeter dial to Ohms

There are a lot of words on the page, but everything is simple and anybody can fix their own electric water heater.
After that, water heater is no longer a mystery and you can save money instead of ever calling service technician again.

Also take advantage of fixya phone service.

Checking ohms on whirlpool dishwasher heating element


http://waterheatertimer.org/images/ohm-reading-for-emements.jpg
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

I tested my hotwater heater and my heating element ohms read 15.6 / 240 volts do i need to replace the element?


http://waterheatertimer.org/How-to-test-water-heater-element.html
What is wattage rating of element?... printed on end of each element
If element is rated 3500 watt, then 15.6 is ok
4500 watt should be around 12.3
BUT you also have to test element for short to ground, as shown in link above

Electric Water Heater blows fuse, but only every few years


Your residential water heater is not 9000 watts. Or it would blow the fuse every day and melt the wire. Instead, you have dual-element non-simultaneous 4500 watt water heater.
http://waterhatertimer.org/How-it-works.html
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html
Look at label for 'total connected watts'
http://waterheatertimer.org/images/Whirlpool-energy-smart-watt-rating-IMG_2600.jpg
25 amp breaker or fuse and 10 gauge wire is minimum acceptable for 4500 watt water heater.
http://waterheatertimer.org/Color-code-wire.html
Troubleshoot blowing breaker or fuse:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#trip-breaker
Why does it blow fuse once each year?? I don't know.
Fuses and breakers trip when overheating occurs on wire.
Each fuse or breaker is rated for heat, and over time, it will get hot and then cool and then get hot again ... this action weakens fuse or breaker.
To solve problem: install 3500 watt elements (and clean sediment out of tank). Wire will run cooler, and fuse will last longer. Whole fuse box will demand less power, and run cooler, and will last longer as a result. So there is less stress on electric service panel.
http://waterheatertimer.org/How-to-replace-water-heater-element.html
3500 watt element will heat water to same temperature, but takes longer. For example: 4500 watt heats 21 gallons per hour, while 3500 watt heats 17 gallons per hour.

Can i replace 4500watt elements with 5500watt on a 606 model


1) Manufacturer's warranty will be voided, and I've never seen recommendation that suggests better heating or saving money from replacing 4500W with different wattage element.

2) That being said, you have 240V water heater.
4500Watts divided by 240 = 18.75 amps
5500Watts divided by 240 = 23 amps

20 amp circuit breaker with 12 gauge wire is rated for 80% of load = 16amps
30 amp circuit breaker with 10 gauge wire is rated for 80% of load = 24amps.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

3) You can use 5500Watt element if you have 30 amp breaker and 10 gauge wire.

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.

Upper thermostats are generic and interchangeable:

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.

I need to know if i have the right element for my water heater. i have the reliance 501 4500w/240v id # 5 40 2ort0 w i want to know if i need the long 1 or the bent 1. would love a pic if possible. i...


Either element will work ... straight or bent.
4500 Watt element will work, buy you can also substitute 3500, or 1500 Watt.
Stepping up wattage larger than water heater nameplate is not recommended, because wiring may not carry more watts.

Element wattage is printed on end of each element.

Reliance is AO Smith company
http://www.aosmith.com/OperatingUnits/Detail.aspx?id=138&ekmensel=c580fa7b_12_0_138_3

Reliance 501 manual is not available on Reliance site.
The 501 used to be standard model, but now it's the 600 series.
http://www.reliancewaterheaters.com/prod/elec.html

600 series manual is similar to your product.
page 22 shows element replacement, and says not to use greater wattage than rating plate on water heater.
http://www.reliancewaterheaters.com/lit/om/manuals/185761-000.pdf

Age of Reliance heater is on serial number. First character is letter. Next two characters are numbers corresponding to year. So C05222,,, serial number is made in 2005.
