SOURCE: The Pilot burner flame is large & yellow

the pilot is getting too much air and is an indicaiot of dirty or air/ fuel ratio imbalance. The pilot is wimpy and the thermocoupler has alot to do with the gas . Make sure your thermocoupler is on the tip of the flame. You may end up replacing it. because it is showing signs of eminnt failure. When it fals your curners won't fire up. Good luck.

SOURCE: cold water ok, no water flow from hot water lines.

Bypass valve incorrectly set
obstruction or dirty tank
plugged line - lime or other! does cold flow into tank ok?
Tank is split water going somewhere you can't see - this should be obvious.

There is not really anything to obstruct the flow normally so there
would have to be an obstruction somewhere. Lime, junk, garbage etc build up .
On my coach I have lots of pressure on the cold side so hot would have to have the same unless there is an obstruction into or out of the tank. If in the bypass position you have sufficient flow than the lines are ok and the problem or obstruction is in the tank itself. Drain the tank, leave the bottom plug out, open up the pressure relief valve. Turn on the water and see if you get a lot of water draining from the drain hole on the tank. There should be a lot of water coming out of the drain hole. If so that tells you that your getting sufficient flow into the hot water tank. If so your problem is the water getting out of the tank. Like a clogged return line or an obstruction from the water tank to the faucet. A dirty scale lined tank can do a number on tank water flow. Also check to see if the water is going somewhere else, your tank could be split and you just can't see where the water is going!

SOURCE: I have a Bosch Aqua

It sounds to me like you tried about everything I would. So I think you're already thinking about what I would do next. Try the flame sensor,and as last resort check all connection . Remove wires one by one clean and reattach. If all else fails change cotrol board. It's very hard to fix when it's not consistent. Good luck. Thanks

Clean air intake located on bottom of heater using compressed air or feather duster. Use auto inspection mirror and flashlight to see under the unit.

Age of water heater appear on label on side of tank.
Look for serial number.
Powerflex is American water heater product (AO Smith)
First 2 digits of serial number is year of manufacturer, digits 3-4 are week during year.

It often flashes ea or af and doesnt want to light


Before calling service technician, open following links for troubleshoot resources including common error codes, Bosch contact information, link to service manuals, and possible product manual
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/2400ESTechSupport/Troubleshooting/tabid/1295/Default.aspx

Call Bosch 800-642-3111
Multiple error codes can mean PC board failure.
AF might be A9, but not sure.
EA is 'no flame ionization detected with water flow'
  1. Verify that all manual gas shut off valves are open.
  2. Check gas type.
  3. Reset error code and open a water tap to cycle the heater in an effort to purge air on new installations. Cycling hot water tap on and off multiple times may be necessary. If heater still faults with EA error code, have a licensed gas technician properly purge air out of the gas line leading to the water heater.
  4. Check three wire connections to ignition group on the lower front of the heat exchanger are secure.
  5. Check gas pressure.
  6. Check venting specifications are met. Improper venting may cause premature failure of the flame sensor rod.
  7. Check that the minimum power fan speed has been adjusted to the proper value.
  8. Observe inside the viewing window of the heat exchanger when a hot water tap is opened. Sparking should be followed by a steady blue flame. If flame is unstable or yellow with proper gas pressure.

Bosch aquastar Aq125-hx does not produce hot water. Pilot is ok. Gas and Flame heat is ok. water pressure is ok. Just no hot water getting to the faucets. Help.


That particular tankless water heater has hydro-generated ignition. In order for it to function, it requires a certain water pressure and velocity. You can try turning on the hot water in two location in your house to see if that gets it started. If it does, try getting a higher flow shower head, or removing the limiters in your faucets.

I barley start a shower and run out of hot water! How can I fix the problem?


If you have electric heater, bottom element might be burned out, or a thermostat is bad.
I wrote a troubleshoot page for electric:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

If your tank is gas, run some hot water and see if burner turns on. See if flame is light blue, or if it's burning yellow. If flame is yellow, the gas valve or burner might be bad. If burner does not stay ON very long, the thermostat attached to gas valve might be bad. Replace gas valve. If the flame is blue and the burner turns on, the tank could be filled with sediment, and it's time to clean it out or buy another tank.

My model 501, 30 gal, LPG water heater only makes warm water, is this fixable, or should I think replacement?


Look at the flame and see if it's burning blue or yellow. And then see if it's burning all the time. If the flame is yellow and water heater does not make hot water, the thermostat may keep the flame going all the time and use up your gas.

Poor flame color means you should clean the burner or replace the burner. If water heater is exposed to trace amounts of some chemicals, like bleach or pool chemicals or wax, these chemicals get pulled into the burner and will shorten life of burner assembly and combustion chamber.

If the flame is blue and the water is not hot, then the thermostat is the best suspect. The thermostat is part of the gas valve. The gas valve has a copper tube that extends into the water and reads water temperature. If thermostat reads incorrect temp, then the gas valve needs to be replaced with gas valve from local plumbing supply of Lowes.

If the flame is blue, and it runs all the time, then your tank may have a layer of sediment between the flame and the water, and the sediment has caused water heater to become very inefficient.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

Now to answer your question:
You can turn up the thermostat dial located on front of tank.
Check your flame and how often burner comes on to determine where problem is.
You can buy a gas valve from Lowes for $65 or from plumbing supply and then replace >> you need a couple wrenches and pipe joint compound and about half a day.
You can clean the burner with wire brush and shop vac.
Remove chemicals from same room as water heater.
If the water heater has sediment build-up, then a new water heater is probably best choice.

You can do some things yourself. If the do-it-yourself steps don't work, then get a new water heater, and you know more about maintaining a water heater because you worked on the old one. Save the new water heater manual. Read the manual because it has ordinary information that will save you money long-term.

Bradford White hot water heater - burner lights only 30 seconds


The slightly warm water makes me think of a thermostat problem. The fact that the heater is 10 years old I wonder how hard your water is. Calcium build up kills water heaters. But the yellow flame you mention could be the results of dirty orfices. May want to have a Pro look at that.
