My ariston 80L water heater not heating water anymore, what's wrong?


You need to replace the heating element or sometimes they have two heading elements. Make sure you turn off the breaker, drain the water, before you remove elements....Do NOT turn breaker back on until water tank is filled with water.

How to replace water heater element will water cme out when you remove element does tank have to be drained


Safest method:
Shut off electricity to heater.
Shut the water valve.
Drain heater to below the level of the element, open hot water valve in house to vent heater to speed draining.
If the element is on top, you don't have to empty the heater.
Remove old element, install new element.
Leave hot water valve open somewhere in the house.
Turn water on.
Once air is removed at hot water valve, turn electric on.
Shut water valve.

How do i replace the heating elements of a rheem model 71-305 electric water heater


Not familiar with this model but most are generic.
Turn the water off;
Release the pressure with the pressure relief valve and leave it open;
Undo the cold water inlet assembly and drain the tank;
Disconnect the element wires from the thermostat;
The elements are held in by 4 bolts. Undo the bolts and remove element;
Installation is the reverse of above.

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...


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.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

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:
http://waterheatertimer.org/Water-heater-will-not-drain.html
c) open covers on tank, remove element using element-wrench from hardware store or home center.
If element won't come out:
http://waterheatertimer.org/How-to-remove-old-water-heater-element.html
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:
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

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

After connecting a drain line to the pressure relief valve of my MR85245 water heater, I now have water leaking badly out of the heating element door.


Turn off the electricity.
Turn off the water valve going into tank.
Open a bathtub spout to let hot water pressure off the tank.
Check top of tank for any leaks.
Open the top access panel and see if element is leaking.
Open bottom access panel and see if lower element is leaking.
The reduced pressure on the tank will slow the leak.

If element is the problem, you can squeak by for a while by turning on the hot water heater only when you need hot water.
Order the 'Marathon MR85245 replacement element' online
http://www.gpconservation.com/rheem/marathon-sp213670-titanium-4500w-lower-element
These elements may be available locally, but they are not the same as 'ordinary' tank-type electric heater elements that you buy at the hardware store.
Buy more than 1 element because the Marathon elements have problems.
One of the reported problems with marathon elements is the high price of stainless steel replacement elements.
Drain tank.
Replace element.

What cause the water heater to take more than an hour to heated up and unable to last longer. Usually its take about 15 min. to heat up and can last longer.


'Rheem 81VP15S point of use' is a single-element, 15 gallon, 120V electric.
Other 'point-of-use' sizes range from 2-1/2 to 6 gallon to 20 gallon.

Electric water heaters have 2 parts: thermostat and element. One is not functioning correctly. Most likely the element caused by sediment build-up.

How to determine if tank has element or thermostat problem:
Do not turn off water going into tank. Put hose on drain valve. Open drain valve. Does water come out like open spigot? If water does not flow, then heater is likely clogged with sediment.

Solution 1: If water flows out like a spigot, the thermostat is probably bad. Read: How to replace thermostat.

Solution 2: Water does not flow, so element is surrounded by sediment build-up and cannot heat water. You need to clean out tank with shop vac, and put in new element ... plan full day and 3 trips to hardware store. Simply draining tank will not remove sediment. Sediment is chunky and will not come out voluntarily.

Buy element before starting:
-Turn off electricity
-Open cover on side of tank, remove insulation (these have to be put back for proper operation of thermostat)
-The are 2 electrical parts >>the element and the thermostat which is located above element
-Element wattage is printed on element and also shows on label on side of tank
-I think Rheem element is held in place with 4 hex bolts
-Take photo of element to hardware store so you have part on hand before removing old element
-If element is 1-1/2' diameter hex type, you need inexpensive element wrench from hardware store + the element

Drain tank and clean sediment:
-Read: To open drain on water heater so water comes out
-Read: How to clean sediment out of water heater

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.

Hot water tank - the hot water shuts off even though there is power to the device


The circuit breaker keeps getting thrown yes? Alright then, you may have a bad element inside the water tank. If you don't know what a circuit breaker is then please call a plumber and do not go near the water heater as it may be a danger to your well being. However, if you do know, then go out there and throw the breaker to the water heater. If you are not sure about this or can not test the voltage at the water heater then do not proceed. However if you are sure, then take off the little covers from the side of the tank and look at the insulation as it may appear moist or wet. There is a heating element inside the tank which can break off, cause electrical shortout and allow water to leak out into the insulation. How to Fix: Shut off the cold water supply at the top of the water heater, then go to the nearest sink and turn on the hot water. There should be no water pressure if you shut the supply valve going into the tank. Now then, leave the hot water turned on at the sink as this will provide a vent for draining the water from your water heater. At the water heater there is a small valve at the bottom which when opened will drain the entire volume of the tank. I suggest that you find and connect a hose to this valve prior to opening it so that the escaping water goes outside rather than on your floor or you could just call servpro and let er rip. Either way, while the tank is draining look on the side of the water heater and find out if it is 240vac or 120vac and write this down. Now look to find the wattage of your heating elements. It might be 1500 watts, 4500 watts or 5500 watts, write down the wattage indicated for the heating element you are about to replace. Write down the brand and the model number along with the voltage and element wattage and go to your local hardware store. Ask one of the older guys (not the kid in electronics) if they would help you select the proper heating element for your make/model and also ask if you need an element wrench to install the heating element which you are purchasing. If the answer is yes, then get that to as you will be needing one very soon. Back home your tank should have drained completely. Now on the face of the old element will be two wires; remove them. Take your nifty little element wrench that you just bought and remove the old element. You will probably be amazed to find that the old element is like, in two pieces, and that's because the rest of it has fallen off inside the tank. If you can retrieve the part left in the tank then do so however it will not be a problem if you can not. Disregard the white hard water build up inside of the tank unless you have the time and capacity to dig all of it out through that little hole. Although, you may need to wallow it out a tad so that the new heating element can fit inside. The new one will replace just as the old one was removed and do not over tighten (it just needs to be snug not twisted off). Replace the two wires; either way don't matter. Then shut the drain valve and open up the water supply on top. Your hot water tap in the nearest sink should still be turned on and now you should hear the air escaping from inside the water heater tank as it is being filled with acid. No just kidding, it is filling with cold water. When the tank is full, water will run from the tap and only then may you shut off the tap. Now with the tank full and the new heating element wired up to the thermostat you can throw the circuit breaker back on. Congrats. Within in 30 mins you will either have very hot water or you will hear an explosion louder than anything you have ever heard in your life. As long as you followed the filling the tank till the water runs out your faucet bit, you should be good to go; go take a bath that is.

Hi..my name is Keith...you can try to blow air into the drain valve to unclog the debris and see if it will drain..but if it has that much debris i think i would replace the hot water heater..also it has a sacrificial rod inside of it..and if it is melted away then the water will eat at your heaters liner and will eventually eat a hole in it...i hope this has helped
