First thing I would do is clean and rebuild the watervalve. The watervalve on this heater mandates everything. This watervalve has a maintenance schedule in the manual. She be rebuilt every 3 years. Also sounds like the diaphram in the watervalve may be damaged.

Need help with Bosch hydropower 13h tankless hot water system


when you turn on the hot water tap there is a pressure switch in the line that sends a signal to a gas solenoid to pass the gas and at the same time to the pizo to start the flame
I would have that pressure switched checked as it may be sticking ( internal contamination) or have dirty corroded points
as gas is involved I would suggest a gas technician do the jib
when you turn off the tap, that pressure switch is shut off so the gas is turned off at the solenoid and the pizo is stopped.

On A.O. Smith water heater model BTH 199 100 where is the heat sensor rod located ?


Parts list:
http://www.hotwater.com/lit/partslists/197728-004.pdf
Flame rod, flame sensor sits next to igniter inside combustion chamber. This can be cleaned with sandpaper. Do not touch with fingers. Purpose of flame rod is to detect whether ignition has caused actual, sustainable fire inside the combustion chamber.
If sensor is bad, or no ignition is detected after 2-3 attempts, then 'no ignition' error is given.
Bad gas control valve, bad-or-dirty flame rod-sensor, low gas pressure, misaligned rod, dirty combustion parts, etc

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 GWH 715 ES flashing EA code. This unit was working fine for over a year so I am assuming gas pressure can't be the problem? The spark is flashing and the unit lights for about 2 seconds then...

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 have a Nortitz natural gas water heater, model #N-063s-1. Acouple of days ago it stopped heating the water. what can I do myself to fix this matter. Thanks, lynnatheana@hotmail.com


There are many reasons a tankless heater will stop heating water. The first thing I would look for is a flashing red light on the burner indicator. The flash break down goes as follows

continuous blinking - typically means ignition failure or the unit is overheating; look for visible water inside the unit, have your gas pressure checked, or check the flame rod/igniter for buildup of debris

three blinks - typically indicates 16 error code; typically resolved by performing a descale

4 or 5 blinks - exotic error codes; for these you should definitely contact Noritz tech support

If there is no flashing light, first check your filter for debris. If the filter is clean, your flow sensor is probably stuck. Again I'd recommend contacting Noritz tech support to help you clean the flow sensor.

The electronic ignition on a gas water heater will not heat up and glow red to ignite the gas to heat the water atwood r/v water heater


You won't see any red glow until the burner ignites and burns for a while. Its only an ignitor and flame sensor, not a glow plug style.The ignitor has to provide spark for gas to ignite, then it also senses the flame and keeps gas flow coming. What exactly is happening when you turn it to on?

Hi Our gas water heater is not igniting


you need to replace the thermocouple its an electronic device that keep the gas flowing . the pilot light is always on and the thermo couple controls the flame. if it goes bad the flame goes out and the burner wont come on to heat the water, they are easy to replace and available at all home depot or a lowes kind of store.
