By poorly do you mean the fan doesn't blow? Does the heater not get hot? Sometimes we just need tho clean the heater, you know get rid of the dust. Some heater also have a filter on the back..if this is dirty the heater won't pout out as much heat.

How do i fix my stiebel eltron tankless electric water heater?It stop working..


Th easy fix would be installing a new heating element that has burned out. You don't say what size this tankless heater but if it stopped working entirely you might have just one heating element inside. You can test it by (1) turning off the circuit serving the heater, disconnecting one of the wires to the heating element, then taking an ohmmeter to see what the resistance of the element is. If it is "infinity" then it is open and burned out. Replace element. If it is around 6 ohms (for a 10kW heater running at 240V) then the heating element is OK. Unfortunately those heating elements don't last forever. Check the repair manual on how to replace the heating element.

New water heater want heat


Need more information.
For example if electricity was turned on before tank was full of water, then elements will instantly burn out.
If upper element burned out, then tank will have no hot water.

New water heater will not heat


Water heater has to be full of water before power is turned on or elements will burn out.
If upper element is burned out, then no hot water.
Lower element burned out, not much hot water.
If tank has 2 elements, it is 240V. Water heater circuit may not be delivering 240V. Test for 240V at connections.

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.

Put in new elements was told they may be the problem that water heater just stopped working but hasn't come back on. Whats the correct process to put in new elements to insure operation of unit


Links below show step-by-step photos:
http://waterheatertimer.org/How-to-replace-water-heater-element.html
http://waterheatertimer.org/How-to-test-water-heater-element.html

If you turn power ON before tank is completely full of water, elements will instantly burn out.
For example if tank was half full, and power was turned ON, the upper element burns out, but lower element is still good.
If upper element is burned out, the tank will produce no hot water
If lower element is bad, and upper element is good, then tank produces some hot water.
http://waterheatertimer.org/How-it-works.html

Another thing to consider is the electric power going to water heater.
You mentioned elements, so you have 2 elements, which is 240Volt water heater.
Check wiring to water heater:

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.

Hot water runs out in 5 minutes it use to last 20minutes


Electric water heater can be repaired by homeowner.

Water heater has some hot water.
We know 3 things for sure:
- electricity is ok
- upper element is ok
- tank does not have overheating problem

Here are the suspects:
- Burned or loose wire
- Upper thermostat not working
- Lower thermostat not working
- Lower element not working

What to do:
1) Turn off power, open water heater covers and look for signs of burned or loose wire, especially on lower element. Burned wire on lower element says lower element is burned out.

2) Test lower element.
Lower elements burn out when sediment builds up inside tank.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html

3) If wires are ok. And you do not want to test parts, then replace upper and lower thermostat for 25$. If problem persists, replace lower element.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

4) If you want to test thermostats and elements before replacing anything:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

5) When finished, be sure to put insulation and covers back on tank so thermostats don't receive cool air and misread tank temperature. This will prevent overheating of tank that causes red reset button to trip.

I have a Reliance 501 water heater, when I take a shower now I only get about 5 min. of hot water is there something on the heater I have to reset? Thnx Mike


Electric water heater is fully repairable by homeowner.
Following information will tell you how.

1) Background on your heater:
Reliance is AO Smith company.
http://www.aosmith.com/OperatingUnits/Detail.aspx?id=138&ekmensel=c580fa7b_12_0_138_3

Age of water heater is shown in serial number. First character is letter. Second 2 characters are numbers, which are year of manufacture. For example 05 is year 2005.

The 501 manual is not shown on Reliance website:
http://www.reliancewaterheaters.com/prod/elec.html

2) Two things known for sure:
- electricity is OK
- upper element is working because there is some hot water.

3) Three things can cause problem you describe:
- Loose wire located from upper thermostat to lower element and thermostat.
- Upper or lower thermostat is bad
- Lower element is burned out

4) How to troubleshoot and repair
- Turn off power, open covers and look for loose and burned wiring, especially on lower element.
- When finished, put back insulation and covers so thermostat not exposed to cooler temperatures.
- Burned wire on lower element is evidence that lower element is burned out.

- If you do not want to follow testing steps below, next step is to replace both upper and lower thermostat for about 25$ and see if problem persists.
- If problem persists, replace lower element.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

5) Test lower element, before replacing anything
http://waterheatertimer.org/How-to-test-water-heater-element.html

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

1 Answer

I just installed a water heater about 11:00 am today but still do not have hot water what could it be


1) Many times people turn ON the electricity before the tank is filled with water.
This instantly burns out any element that is not submerged in water.
If the upper element is burned out, the lower element may be good, but the way the thermostats work, the upper element must heat top of tank before power is sent to lower element.
http://waterheatertimer.org/How-to-test-water-heater-element.html

2) My new electric water heater had same problem, and the red reset button, or ECO, was tripped on upper thermostat.
Open cover and check reset.
