they worked on our city water and now i'm getting no hot water... before that it worked but i don't think to capacity.. it wouldn't fill the tub before getting cold.... it is a rheem 50 gallon electric .. not sure if i need a new one or not.. any advice appreciated

As long as the water heater is not leaking or not big enough that would be the only reason to replace heater. If you are running out of hot water or it's cold, check the power source first to make sure you have power to heater. Then check the reset button on the top thermostat and make sure it's not tripped if it is it wil not heat. If so press red button aloow it a little time check for hot water.
Next step woul dbe to turn power off and drain water to replace both elements out. Once changed out turn water back on and open a faucet to remove air out of the wtare lines. Once you get water flowing out of water lines now you are ready to turn power back on. allow about 30 to 40 monutes and you should have hot water.

Hi, I also have a SHS43E08GB/43 and need to replace the instantaneous water heater element. I can see that people have asked for some help with getting access to the unit. any chance of a 'heads up' on that one too. I've checked the circuitry and there doesn't seem to be any burnt out connections so the instantaneous water heater is next on my list. Any and all hep gratefully received Chris

Replacing the Water Heater Element Step 1: Turn Off the Power
  • Turn the circuit breaker off at your electrical panel, and use a voltage tester to check if power is still reaching your water heater. You will be working with electricity and water, so it is critically important that the water heater is turned off and is no longer receiving electricity.
Step 2: Attach Hose to Drain Valve
  • Attach a hose to the drain valve and turn the knob to open the valve. At this point, we do not want to drain the tank, only to make sure that the drain valve is not clogged.
  • If your tank is clogged, you will need to address this issue first.
  • Do NOT drain your tank yet.
  • It is possible to change the heating element without draining your tank, although it can be a bit more challenging. If you would like to try, this video will show you how.
Step 3: Turn off Water to the Water Heater and Release Pressure
  • Turn OFF the water supply to the water heater, by closing the cold-water inlet valve which is located above the water heater.
  • Release the hot water pressure by allowing air into the tank. To do this, open a nearby faucet in a bathroom or kitchen. Only open the hot water valve, not the cold. Leave the valve open.
Step 4: Remove the Access Panel
  • Use a screw driver to remove the access panel. The upper panel houses the upper water heater element, and the lower panel houses the lower element.
  • There is usually insulation between the panel door and the thermostat, set the insulation aside in a dry place.
  • The thermostat should have a plastic cover, gently remove the cover.
  • Check the wires with a volt meter to ensure that there is no power.
  • Inspect the wiring. Has any of the wires been damaged? Are there any melted parts? Wiring can be damaged if sediment has caused an element to overheat. Any damaged wiring must be repaired.
  • Loosen the screws and disconnect the 2 element wires from the heating element.
Step 5: Remove Heating Element
  • Use a heating element wrench to remove the element. The element wrench can be purchased for about $5 at your local hardware store. It is designed specifically to remove electric water heater elements, and has a wide mouth that will fit over the exposed part of the element.
  • While the tank is still full of water, slightly loosen the element in a counter-clockwise motion. The water's weight will help keep the tank in place.
  • Once you know you can loosen the heating element, you can now drain the tank by opening the drain valve. Depending on the size of your tank it could take between 30 to 60 minutes to fully drain.
  • Remove the element. There will be a rubber gasket or "O" ring that seals the tank. Be sure you remove the O ring with the element.
Step 6: Install New Heating Element
  • Wipe down the threads and gasket area of the new element so that they are free of dirt or debris.
  • Attach the new O ring onto the new element. DO NOT use the old O ring.
  • Gently push the element into the tank and tighten with the element wrench.
  • Attach the 2 wires under the element screws. Be sure that the wires are secure and will not slip.
Step 7: Refill Tank
  • Close the water heater's drain valve.
  • Turn ON the water to the water heater.
  • Do NOT turn the power ON at this time. The tank must be full of water before turning on the power or you will damage the heating elements.
  • Check the newly installed water heater element for leakage. If leakage is present, turn off the cold water supply and tighten the element. It may be necessary to remove the element and reposition the O ring.
  • As the tank fills, water will begin to sputter from the open faucet tap that was left open from Step 3. The water is pushing the air out of the line. Once there is a steady flow of water, the faucet can be turned off.
  • Replace the plastic thermostat covers, insulation and access panel covers.
  • Once the water heater tank has filled with water, you can turn the power back ON to the water heater by flipping the circuit breaker ON.
?It's not uncommon for the hot water faucets throughout the house to sputter, as they will likely have air in the line. This will go away in a short period of time, you can open each faucet until you have a steady flow of water if you prefer.

how do I change the heating element on my 50 gallon electric Reliance 501 hot water heater? Where can I get the heating elements?

Buy elements at local hardware store or home center, like Lowes
Look at label on side of tank.
Label shows element wattage.
Element is also printed on end of element in tiny letters-numbers.
Typical elements are 4500 and 5500 watts.
Tank needs 10 gauge wire and 30 amp breaker for 5500 watt element.

Water heaters are fully repairable by homeowner.

1) Have you tested water heater to see if element is problem? You need cheap multi-meter from Home Depot.

2) To change element
a) turn off power
b) drain water from drain valve ... once it starts draining, loosen element slightly while tank still has weight to hold against you turning element wrench.
Here's what to do if water heater won't drain:
c) open covers on tank, remove element using element-wrench from hardware store or home center.
If element won't come out:
d) Clean out tank if needed.
e) Replace element.
f) Fill tank entirely with water before turning on power or element will burn out.
g) Once tank is filled, and water flows steady out of tub spout, turn on power.
Each steps above is shown on following link:

3) You need to buy some things:
Screw-in type (not bolt-in type) Element that matches wattage on tank label. New Element comes with washer.
Inexpensive Element wrench.
Inexpensive multimeter if you are going to test parts first.
Some pieces of pipe and hose if tank sediment needs to be cleaned out.
Washing machine hose if tank will not drain (return after job is done).

4) Also:
You need flat tip and phillips screwdriver.
Lighting to work on tank
Some WD-40 if element is stuck in place.
Garden hose to drain tank.
Shop vac and duct tape if you need to vacuum out sediment.
Tarp to protect floor and carpet
Maybe a knife to cut back insulation on wire if wire is burned at element.

Web links above go through entire process step by step.
Add a comment if you need more help, I'll be back around 5 CST

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.

leaking water tp valve

Turn the fuel source off to the water heater (gas/elect).Shut the water supply off at water heater, connect a hose to the drain **** at bottom of tank. Open the drain **** remove the T&P drain line . When hose starts draining slow open up T&P and unscrew it from tank replace it with the proper T&P.Use a thred compound rated for temps above 210 deg F Put on male threds, install same as removal. The T&P valves drain must have 1 air gap ! fill water heater with water check for leaks,turn power source back on. P.S.check the T&P at least once a year for defects. Good Luck
