Diagnosis Electric Hot Water Tank Problems and Repair It

I understand that you electric hot water tank is not producing hot water. To diagnosis the problem we will need a few tools. Here is a list of the tools you will need.

Screw driver (Flat and Philips)
¼ inch nut driver or ratchet and socket
5/16 inch nut driver or ratchet and socket

Diagnosis Electric Hot water tank problems:

1. First you will need to remove the service panels on the side of the hot water tank to expose the thermostat and heating elements. Careful as power is still on to the unit. Now that you have removed the service panels we need to proceed to the next step.

2. On the thermostat there are two wires coming into the top two screws these are line one and line two they are the main power feed. Take your probes from the multi-meter and touch to each screw and you should receive a reading of 220 volts. If you receive this reading then move to the next step. If you do not get a 220 reading then your breaker is tripped or bad.

3. Got the proper power then you will want to check the thermostat reset button. In the middle of the thermostat is a red button press it in and see if it clicks. If the button clicks it means that the thermostat has tripped do to over heating. Wait an hour and see how your hot water is doing. If still the same replace the thermostat.

4. Use your multi meter to check for power to the heating elements. The heating elements have two screws with wires on them. You will want to take one probe to each screw and see what the VAC reading is (if power is present you should receive 220 volts) if you do not get the correct reading then the thermostat needs replaced. You will need to do the same thing to the lower element.

5. To check the heating elements turn off the power to the unit at the breaker. Check to make sure the power is off by using your meter at the thermostat. Remove the wires off of the element and check it for continuity if not continuity then the element is bad and needs replaced.

Replacing the Thermostat

1. Turn off the power.
2. Label and remove all wires from the thermostat
3. Pull clips forward on sides and pull thermostat upward to remove
4. Install new thermostat in reverse

Replacing the Element(s)

1. Turn off power to the unit
2. Turn off water to hot water tank and drain
3. Remove element from tank
4. Slide new element in tank
5. Turn water supply on and check for leaks
6. Reconnect wires
7. Turn on hot water faucet some where in the house to allow air to escape from tank.
8. Turn power on once hot water tank is full.

Water heater supplies about a pint of hot water than turns cold?? what is th eproblem

Hello Rsjohnson164,

I understand that you are having a problem with your hot-water tank not producing any amount of hot-water. I would suggest that you turn off the cold water supply to your hot water tank and drain the tank and see how much water comes out of it.

Flush the tank:
1. Turn off the cold water supply
2. Hook a water hose to the boiler valve (spicket on the bottom of the tank) and turn on the valve
3. Turn on the cold water inlet line and let it run for about 15 minutes or until you get good pressure coming out.

Check the Elements:
1. Turn off the power to the hot-water tank
2. Remove the service panels
3. Remove one wire from the element and use a multi-meter to check continuity
4. If no continuity replace one or both elements

If you do all of this and still have a problem repost to this thread and we will check your thermostats to make sure they are working properly.

Thank you for choosing

Bought a hot water heater made by whirlpool for 2 weeks only had enough hot water to fill 1/4 of the tub then the water turned cold . They have replaced the hot water heater and still has same problem....

The down tube in the tank has fallen off or the hot and cold lines are reversed at the tank. I'm going to assume it is gas , if its electric you need to test the heating elements for continuity and temp settings. as well as the down tube in the top of the tank that sends the cold water feed to the bottom of the tank..

Water Too Hot

needs new thermostat(s) If the whole tank is heating( next time it trips, before using any hot water check the lower tank thru the lower element access(breaker off) If the lower tank is hot-you need a new lower thermostat. if just the upper part of the tank is heating -you need an upper thermostat.

I have a giant hot water heater which is 12 years old and it provides hot water for only one normal shower. Why so little heat? Does it need to be replaced or is there something else that should be...

You probably need to replace the water heater. Water heaters accumulate a build up of lime and other mineral deposits that are present in water. This covers the bottom of the tank and heating elements over time, and makes them operate inefficiently. Draining the tank periodically helps prevent this from happening, but once it has reached to point you explained, it is best just to replace it with a new one.

Warm water only

You can eliminate the shower control knob possibility by turning on your hot water anywhere else in the house. If you get hot water in other places, then it could be the knob causing it. A substantial lime buildup in the tank can also cause poor heat transfer from the elements to the water.

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.

Hot water lasts half the time

How old is the heater?

It may be something as simple as just needing to flush the tank to remove any sedemints....and hopefully so because this is the easiest/cheapest thing to do.

If this is not the case go ahead and remove the heating elements and check for wear. Replace them if necessary. I would also replace the thermostats that accompany each of the elements.

Checking and replacing both of this requires you to drain the tank completely and should be close to $25 total....last time I checked.

Rinse not hot enough

145 degree is just your hot water temp and that your dishwasher hot water booster is not working assuming that this machine has worked in the past to produce final rinse water above 180 degrees. Remove the bottom panel and to the right you will see the booster tank, look for a nickel size component with a small red button on it. Try pushing on it to reset it. If that does not work, check for voltage at your heating element on your booster tank. (the thicker wires) If voltage is present then your heating elements need replacing.
