SOURCE: Pool heater leakage

Chances are that the header or manifold is cracked. usually the heat exchanger themselves are not damaged from freeze, but either the rear manifold (header) or the front header (the one that pipes go in and out of). Sometimes both. Replacing the entire heater is not necessary, about $200 in parts usually. We have a schematic diagram of the LJ heater here: http://www.poolcenter.com/parts_heaters_lite2_lj_2003-present_pg1.htm

SOURCE: heater will not heat

If you dont smell any gas make sure that all gas valves between the heater and the main gas meter are open, and the gas valve in the heater is in the on position. Try cleaning out the nozzles that the gas comes out of. Sometimes they can build up with cobwebs.

SOURCE: SPA Filter on while Spa is Heating

you have one jandy valve ( the suction valve in front of the pump) that is not working right when you press spa mode. have someone watch the valves to see if they move when you press spa mode and heat inside the house. if the one in front of the pump does not move and the switch is in operating mode then that valve is bad and will have to be replaced.

SOURCE: my spa won't blow bubbles but it will heat up. It

You opened the air valve??? Usually a round thingy on the edge of the tub.

I cant imagine how this would not work if it were open ... it works on the same idea as a carb on any gas engine. If the hole is open, the water stream will **** in air.

SOURCE: heater will fire, will heat for one hour then

you didn't indicate exact model but here is what the AGS is for.
Not sure if yours has a combustion blower or not, if so check that it's flow is not obstructed. If it doesn't make sure there are no debries in the flue area. Here is the troubleshooting from their manual. You can download a manual from www.jandy.com
AGS
(automatic gas shut-down)
1. Oscillating pump pressure. 1. Clean filter or identify and repair cause of pump
oscillation.
2. Low gas supply pressure. 2. Identify and repair incorrect supply pipe size or
pipe line blockage.
Refer to qualified service personnel.
3. No flame at burners. 3. Identify and correct loose wiring connections, or
problems with igniter, flame sensor , gas valve, or
ignition control.
Refer to qualified service personnel.

Why the hot water temperature couldn't reach the set temperature (130 degree) in Amtrol WHS80Z indirect water heater?


I have a couple of thoughts. You may have air in the boiler water circuit at the loop that feeds the tank. You'll have to find the vent in the loop to get it out. Second, the automatic valve that opens for hot water may not be opening fully. Have you felt both the boiler water lines that go in and out of the tank? If the water going in is hot and the line out is very cold you have very little boiler water going through the loop. Make sure the isolation valves on the loop are open. Is your boiler full of water? If the boiler loop lines are hot going in and coming out, the tank is full of rust or debris and no water can get to the fins on the internal tubing to pick up heat. If that's the case there is no repair and its time to get a new tank. Hope this helps good luck.

I have an 80 gallon Rheem Hot water heater #81V80D A. In the last 5 days it stopped heating water after 6PM. I have hot water all day, but none at night. What do you suggest?


1) I bet the water heater has hot water, but hot does not arrive at tap because of bad faucet cartridge or bad recirculation system check valve
http://waterheatertimer.org/Crossover.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#crossover

2) When cold water arrives at tap, go check if water heater has hot water. Then do the crossover test. Then add comment and say what you discover

3) Electric water heaters can be repaired by homeowner using generic off-the-shelf parts from local hardware store.

My reliance sta-kleen 502 is leaking. The water is dripping on top of the pilot light, extinguishing the flame . Please advise me with step by step instructions to diagnose and attempt fix this myself....


If you have a leaking water heater there is a serious problem.
http://waterheatertimer.org/Water-heater-leaking.html
Page shows how to limp along on a leaking water heater if your water heater needs replacement.

One of three things is causing the water:
1) Loose water connection on top of tank that is dripping down inside tank >> check pipes on top of tank.

2) The vent is clogged or not working correctly causing condensation inside flue pipe.
Condensation water is dripping back down inside tank.
Problem means possible CO poisoning if gas is not venting.
Look at vent pipe to see if joints are corroded.
Use long fireplace match > light match and put into draft hood at top of tank and see if smoke goes up.
Put hand at draft hood opening when water heater turns on to see if vent gas enters home.
Do same test when furnace turns on to see if furnace vent is pushing back into water heater.
Does water heater vent inside same pipe as furnace? You may need to set up separate vent for water heater if furnace gasses are pushing back into home.
Check furnace vent for obstructions.
Look at vent stack top of home to see if hood is in place.
Check if bird nest is built inside warm vent pipe.
Improper flue is top priority for getting fixed so vent gasses properly escape home.
You may have to call a plumber.
Professional plumbing forum:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

3) Your water heater is rusted out.
A rusted tank has to be replaced.
It cannot be repaired.
However, before replacing tank, you do not want a tank failure where tank ruptures and water runs inside home until water is shut off.
This will cause major damage.
Protect yourself first.
Turn off water valve above tank.
Move gas knob to 'pilot' so burner is not heating water.
Open tub spout on hot side to relieve pressure on tank so it will not rupture.

Now you're protected.
Link above shows how to limp along on failed tank until you can replace heater.

You need a new gas water heater from Lowes or Home Depot
Look at label on side of you tank for gallons and btu's of your water heater.
Measure height to flue pipe so you get same height water heater, so pipes don't have to be changed.
You need a pipe wrench and teflon tape which will be wrapped on each pipe thread when pipes are reassembled.

Step1) Drain water heater using valve at bottom of tank.
http://waterheatertimer.org/Water-heater-will-not-drain.html

2) Turn off gas valve going into heater.
When gas valve is perpendicular to gas line, then gas is off.
Dissemble gas line to water heater.

3) Disconnect flue pipe and support flue pipe with wire so it doesn't not fall down. Flue pipe joints should be held together at each joint with 3 screws.

4) Turn off water. Shut off valve is on COLD side.
Disconnect water pipes.

5) Move old water heater out of way.

6) Set new water heater in place. Put water heater in drip pan.

7) Connect water pipes >> cold goes to side marked cold.
Hot to hot.
Buy new flexible water connector pipes at home center for easy installation of water pipes.

8) Connect gas line exactly as it was connected before.
Home center sells flexible gas line connector for easy installation of gas line.
To test for gas leak after installation, mix liquid soap with water and put around gas line joints to see if there are bubbles.
Natural gas has less pressure than water lines, so gas pipes are easy to seal with ordinary wrench.

9) install TP pipe that runs to floor. Use old one off old heater.

10) Fill tank completely with water until water is coming out of tub spout.

11) Turn on gas, and light pilot as shown in manual.
New gas heater sometimes have small water leak when first fired up, so ignore a bit of water.

12) Save water heater manual like it is gold, and read everything in manual.

What is the energy factor for the mod.82V80-2? I have two seperate 30amp circuits, one for the top element and one for the bottom element, if that changes anything.


http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619
http://globalimageserver.com/fetchDocument.aspx?id=052c9e32-ce37-48d7-8990-9e430f23fef3

82V80-2 Energy factor is .86 according to water heater industry self-regulated standards.

Rheem pdf says these water heaters are wired for non-simultaneous operation.
Except special order water heaters.
Non-simultaneous operation uses single 240V circuit as described below.
If your water heater is wired for simultaneous operation, and each element is on a separate circuit, that makes your water heater special order. I would guess the reason is for higher first-hour delivery, which implies rapid heating and would likely affect energy factor.
You might want to get serial number off model and call Rheem for specs on that special order.

Your water heater energy factor may be the same because 'energy efficiency is based on the amount of hot water produced per unit of fuel consumed over a typical day.' This means an aircraft carrier can be considered highly efficient despite overall cost. And naturally the guys making the aircraft carrier are also doing the rating.
http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13000

Non simultaneous operation means the upper thermostat controls heating functions.
240V goes to upper thermostat first.
When water inside tank is cold, thermostat reads temperature through tank wall.
Upper thermostat turns on upper element until top 2/3 of tank reaches thermostat set point.
Once set point is reached, upper thermostat turns off upper element and sends power to lower thermostat and lower element.
Lower thermostat reads temperature through tank wall, and turns on lower element until bottom 1/3 of tank reaches thermostat set point.
As water cools inside tank, lower thermostat is first to respond since hot water rises.
Lower thermostat turns on lower element until tank again reaches set point.
When hot water faucet is turned on, hot water exits top of tank.
At same time, cold water enters bottom of tank through the dip tube.
The heating cycle repeats.
At all times, the electricity flows through upper thermostat. And upper thermostat is powered by one 240V circuit.

With simultaneous operation, the upper and lower thermostats work in same manner.
Except thermostats are wired separately.
Lower thermostat does not wait for upper part of tank to be heated first.
Lower thermostat turns on whenever lower part of tank cools.
The advantage is more hot water available rapidly when demand is high. This is called first hour recovery.

One method for reducing electric consumption is to set lower thermostat so it only turns on during certain times of day. For example Whirlpool Energy Smart operates in this manner and shaves a few bucks off the bill each month. This says that simultaneous operation is not an energy saver, unless that circuit controlling lower thermostat is set on a timer.

This is an error code 12, not 12 degrees. You have a short on your low voltage side by the sounds of it.. First disconnect the controllers inside the heater. Turn of the power first, 2 screws top and bottom to take the frnot panel off. Follow the low voltage wires (not the power point ones) to the PCB on the ride side and disconnect them both. Panel back on, power on and try the heater again. If this fixes it you have a short circuit in the controller or the wires leading to it. If not the most likely short circuit is on the thermal fuse which loops around the heat exchanger. This will need an expert, Perth has plenty north and south of the river. Give Rinnai a ring first, they have some good staff in Perth who might help.

Whirpool Quiet III Clean light blinks


You, my friend, have the dreaded 'blinking clean light.' This means that the electronic control has detected that for three consecutive cycles,
1. the heater hasn't come on
OR
2. the water hasn't come into the dishwasher
OR
2.5. the water came in, but wasn't spraying around inside.
OR
3. the heater came on, but the temperature probe did not detect a 3 F degree rise in temp in a certain alotted time. (Is the water supply unusually cold?)

Originally, this fault code could happen if any of these happened just once. Now they program the elec control to wait until the 3rd consecutive ocurrence.
First, let's clear that fault code.
Since you did not mention any unusual sounds, I will assume the water is filling and spraying around inside.
Press 'heated dry', 'normal', 'heated dry', 'normal'. This activated the test cycle, and clears any fault codes. After 10 seconds, press 'cancel'. Open the door and carefully see if the heating element came on. (It should be hot.)
If it did come on, it's an intermittent problem, and could be related to the door switch. Some earlier models would allow the dishwasher to run with only one of the two contacts closed, but the heater would not come on. Be careful to close the door tight each time. They have redesigned the switch (or is it the door latch?) to ensure both contacts get closed.
If the heater did not come on, then you might need (in order of higest to lowest probability) a heater, a heater thermostat, or the electronic control board (heater relay.)
I haven't ever seen a failed temperature sensor, though it is theoretically possible.
You can continue using your dishwasher until it is repaired. Though, you may have to reset the fault code 2-3 times a week.

Good luck!
