Have sta kleen 805 , have power,240 v no hot water

1 Answer

If I understand correctly, your water heater circuit tested for 240 Volts.

1) If circuit has power on one leg of the 240V circuit, water heater can appear to have electricity, but won't turn on since 240V needs both legs to complete the 240V circuit. Solution: test for 240 across top two screws on upper thermostat.

2) ECO reset button tripped on upper thermostat. Solution, push in reset button. If reset will not reset, then replace upper thermostat. I usually replace both upper and lower thermostats at same time: cost $28. Buy parts from home center or hardware store. Be sure to put factory-insulation and covers back so thermostat is not exposed to cooler outside temperatures, that cause hotter water than set point.

3) If ECO reset button keeps tripping, then keep resetting until you can test water heater parts. Spend 30 minutes and do complete troubleshoot on tank.
Buy cheap multi-meter from home center. When test calls for checking voltage, rotate dial to 240-250-277 VAC. When test calls for checking continuity or elements, rotate dial to Ohms (upside down horseshoe is ohms).

We have a reliance sta kleen 805 lp water heater that we installed used and it will not let us go through the start up procedure. i assume its in some kind of lock out mode, it does not respond to hot...


Used, Reliance 805 is power vent gas
10 year old water heater that is newly installed.
Unknown gas control valve.
I'm not a fan of installing old power vent water heaters.
Usually these things are so expensive that old one is only replaced when it fails.

120Volt Outlet must have correct polarity and unit must be grounded between ground prong on cord to manifold tube connected to bottom of gas control valve. Test for continuity with multimeter.

Is this an early FV model with air intake located on bottom?
If air intake is clogged with dust, then combustion chamber overheated and tripped FV system. The older heaters need replacement parts and new gas control valve, or entire heater must be replaced.

Replace gas control valve.

Replace thermocouple gas water heater


Thank you for the brand. Approx how old is water heater? 2nd and 3rd digit of serial number are year of manufacture.
For general instructions:
http://waterheatertimer.org/How-to-replace-thermocouple.html

Reliance is AO Smith, and air intake is located on bottom of tank.
Inspect and Clean intake.
Do NOT underestimate need to keep air intake clean because the arrestor screen is fine mesh and once clogged will cause heater to fail. Older models might need full replacement and at least parts.
http://waterheatertimer.org/images/Flame-trap-inspection-325.jpg

Product manual?
These gas water heaters are changing quickly today. The Reliance site shows the 909 but not 805
http://www.reliancewaterheaters.com/lit/om.html
The older designs are different, but instructions shown above will help.

Rheem rte13 standby (green) light not on


You might have crossover problem caused by bad faucet cartridge.
http://waterheatertimer.org/Crossover.html

The green standby light should come on when 240Volt power is applied. Page 6 manual.
Both red lights should come on when tankless is activated. Page 6 manual

RTE 13 requires 60 amp breaker and 6 gauge wire
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html
http://waterheatertimer.org/pdf/Rheem-TanklessElectricUC_AP15447.pdf

Factory temperature setting is usually default 120 degrees.
Adjust temps page 11 manual
Thermostat calibration is always approximate.
120 degrees is not hot enough to burn the skin.
Exceptionally cold incoming water temperature can cause tankless not to heat enough hot water: install tempering tank to preheat water to room temperature.
Tankless cannot be exposed to more than 11 grains hardness in water. Delime tankless yearly, clean water filter monthly, do not install low-flow restrictions or conserve water since the flow rate must remain high for tankless to activate.
Rheem does not post service manuals for their tankless water heaters.

I have a Reliance Sta-Kleen 805 Electric Water Heater that is leaking from the cold valve but the water is coming out hot. How do I repair it?


If I understand correctly you have residential electric water heater, and your shut off valve located above water heater on cold-water line is leaking?

1) Hot water would come out of this valve if it's leaking because water inside tank is hot and under pressure ... also remember, hot water rises so tank is probably heating the water inside the cold line during hours when no hot water is being used.

2) You probably need to replace the valve. But if water is leaking because a pipe is rusted, the valve may be ok, and just the pipe needs to be replaced.
Take a photo of your problem to hardware store or home center.
I used to work in those stores and could help folks get the right parts.

3) Here are some steps for replacing the valve.
Shut off main water source into house. This is usually located underground in same box where meter-reader looks at meter.
Your water heater shut off valve is called a gate valve, and it will be 3/4"
All water heater pipes are 3/4"
You will need two 10-12" pipe wrenches, maybe a new gate valve, maybe a new flex connector, probably short 3/4 pipe pieces, teflon tape for each threaded pipe.
Hardware store or home center can get you the right materials, just take a photo over to hardware store

4) When you get started, turn off water heater circuit breaker for a couple hours so water will cool down. You don't want to get scalded with hot water.
Do NOT drain the tank.
Simply open a bathtub faucet on hot side to release pressure.
When finished, turn on the water, and make sure water is flowing out of tub spout in full stream before turning circuit breaker ON

I replaced all parts but water heated won't get hot


You have electric water heater.
You replaced elements and thermostats but heater still won't work.
And tank was completely full of water, and water was running out of a faucet before turning power ON.
If elements are not fully immersed in water, they will instantly burn out.
If upper element is burned out, then tank will have NO hot water.
If lower element is burned out, and upper element is not burned out, then tank will have some hot water.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-it-works.html

If elements did not burn out, then that leaves 1 main suspect: the electricity.

1) Push in ECO red reset button on upper thermostat. If ECO is tripped out, then heater will not work.

2) Click circuit breaker all the way one direction and then back the other direction to make sure breaker is latched.

3) If tank has 2 elements, then it is 240volt.
If 1 leg of 240Volt circuit is not working, then 240V appliance will not work.
240Volt circuit needs both hot wires to complete the circuit:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html#120-240

Buy cheap multimeter from Home Center and set dial to 240-250-277VAC
Tape tester leads to woods sticks to keep hands away from power.
Power is ON
Test across top 2 screws on upper element should show 220-240 volts.
If you have 240 at top two screws, then skip down to step 6.
If no reading across top two screws, then move to top of tank.

4) Open connection point where wire connects to heater.
Test across both insulated wires should get reading of 220-240 volts.
If no reading, move to circuit breaker box.

5) Mark water heater breaker.
Turn off all breakers except water heater breaker and main breaker. (and breaker to light fixture where box is located)
Do not hold or touch or lean against anything metal.
Stand on dry boards and wear dry clothes.
If main breaker is OFF, the big wires that connect to main breaker are still HOT.

Remove box cover.
240Volt breaker has 2 wires connected with screws.
Test across both screws for 240Volt.
See if wires are loose.
If there is no reading, then breaker is not working on one leg.
To double check, move water heater wires to another same-size 240V breaker and then put ear against water heater to listen for bubbly-fizzing sound.

6) If you are getting 240 to water heater, then wire inside tank could be loose.
Do 30 minute troubleshoot:

Hot water heater


Absolutely no hot water indicates the top element or thermostat on the heater. Check to make sure that you have 240 volts on the top two terminals of the top thermostat. If you do then check the top element for voltage. It should also read 240 volts between the two screws. If you have 240 volts there shut off the power, drain the heater to a point below the top element and change the top element. When the element is installed turn your WATER back on and let the air bleed out of several hot faucets in the house. When the faucets stop spitting air you can turn them off. Check for leaks around the element. If you have no leaks turn the power back on the the heater and replace the covers.

That should get you 'back in hot water' in two hours.

No hot water


If the water does not heat, then you have to troubleshoot to find the problem. With a voltmeter determine if 240VAC is actually getting to the water heater. Take care here - a defective circuit breaker can give a false 240 volt reading - check for the 240 volts across the upper element (i.e. when the 240 volts has a live load on it, not just an open circuit test).
Also, remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.
