Bosch gas Analyzer

My 15 year old bosch Gas analyzer has lost its memory because a small button battery that I did not know it even had has gone flat. I have fitted a new battery but can not reset the program. the manufacture Bosch say that it needs a new board as it can not be reset by the user.but the board is not available and it seems an awfull shame to scrap such a good machine just because it needs the programe reloading. Can anybody help.

    thanks for your help I have tried most of your suggestions but not the 5 second shift I'll try that in the morning I am sure there must be a sequence of options on the various buttons to reset this but no one seems to want to let me in on the secret.
    thanks again...hawkmount

Hmm....interesting issue. Let me try to point you in some directions that "might" help. First of all, with a computer motherboard, removing the battery and replacing it is the equivalent of shortening the pins to reset the "bios"....that funny name would be the equivalent to your software in all probablilty.....so having said that are there a couple of pins next to the battery and do you see a black or white (usually) small removable pin connector. If so, try moving it to another position...count to five...continue that process until you have covered all combinations and then return it to the original position. The boot (turn on) your machine again. Do this with power off obviously. If that fails ask Bosch how much to reset your board...just for drill but who knows it might be cheap. Also try to get to a "real" tech. The guys behind the front line help support. Most of them I suspect would give you the procedure unless company policy and $'s dictate an unhealthy policy. Failing that write a letter (polite) to the company....in fact send it to a number of people and locations including a few up the food chain (as in board of director's)....express your satisfaction with the machine, blah blah...and then wait.

I assume there is nothing on their website nor on the internet but you might check the former if not done and google the internet with a variety of search statements. You might get lucky.

Also...most EE's (electrical engineers) would not intentionally design a product that "died" when the battery life ran out. You might want to try pressing various combinations of keys on your analyzer...the reset feature is more than likely there. If not then it was apparently an intentional design ....in other words their way of getting you to buy new.

Two last things....depending on usage (I am guessing it's not used significantly) if you have less than 3-4 years continuous usage pursing all the above is worth it. If you have 7 or more then the "solid state" portion of the device may be nearing it's end of life...MTBF....mean time between failures. If you have 4 to 7 it's up to you. You might also put a "want it" on Ebay and similar sites and just store it for a while. You might come up with another machine...working...cheap.

Hope the above helps....Tango.

1999 regal buick using alot of gas terrible gas milege


It has fuel injection and something has gone wrong with the injection system. This is not something that can be fixed by pushing a button or with a hammer and pliers. Someone who knows what they are doing is going to have to hook it up to a real analyzer, not a 30 dollar autozone toy, diagnose the problem and fix it.

A dealer or a real repair shop come to mind.

Igniter can be ordered, but that may or may not be the issue.
Your tankless unit -and- plumbing system need total check-up by trained service technician.
Open following links for Bosch troubleshooting resources including contact Bosch, manuals, error codes, water flow etc.
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
http://waterheatertimer.org/pdf/No-Error-Code.pdf
Check electrical outlet with circuit analyzer to make sure polarity is correct.
Typically, gas water heaters, and especially tankless water heaters require yearly maintenance by service technician who can check the gas pressure and supply, venting, electrical connections, PC board, sensors, burner orifices and igniter parts are clean and positioned correctly, vent is draining correctly and not dripping back into combustion chamber, correct temperature is achievable, incoming water temperature is not too cold for temp setting, proper incoming air supply, adequate air supply, no chemicals stored in air supply pathway, filters are clean, plumbing check valves, mixing valves, pressure valves etc are permitting one-way flow of hot water, water is softened to less than 11 grains hardness, water is filtered and not dirty, aerators and other faucet parts are clean and support water flow necessary to activate burner.

Most gas water heater problems today can be solved with yearly maintenance that includes cleaning burner parts, clean air intake, check venting, check electrical connections, bleed gas line, and check gas pressure.
Gas water heater manuals recommend yearly maintenance by service technician.

In past years, gas water heaters required less maintenance, but they were less energy efficient and more dangerous to operate.

Sounds like you have Intellivent gas control valve thermostat.
Open following link to identify gas valve and see error codes:
http://waterheatertimer.org/pdf/Intelli-vent-gas-valve2.pdf
http://waterheatertimer.org/How-to-adjust-temperature-on-water-heater.html#intelli

Error light on vacation + 2 other lights = 3 possible conditions:
1) Wiring error: check outlet with circuit analyzer:
http://waterheatertimer.org/images/Typical-circuit-analyzer-15.jpg
2) Pressure switch tubing not connected, air intake obstructed (clean intake), or vent exhaust obstructed (check for proper venting).
http://waterheatertimer.org/images/Test-water-heater-vent-400.jpg
3) System in lockout: Low gas pressure, hot surface igniter not positioned correctly.

You can do some of this yourself.

Bosch vision 300 gas dryer shows error E12 evry few min. Checked and cleaned lint. Checked exhaust vent. Still E12 every 10-15 min. The dryer is only 6 months old.


A friend of ours has a bosch gas dryer and she had the similar problem. She called the Bosch repairman and he came out to her house and sprayed the lint filter with Greased Lightning to clean out the tiny holes in it. He charged $100 and left. He said it would take care of the problem. Has not had any problems since. http://www.greased-lightning.com/ It is worth a try. Good luck.

Error code E9


High pitched noise is from a very high CO2 level. Adjust the gas pressure to stay above 11" w.c. and have a gas technician with a calibrated CO2 analyzer adjust the CO2 levels.

I have a 250SX aquastar Bosch tankless hot water heater . It keeps going out on EC code; whats wrong? Also I've been running the unit for about a 9 months without hooking up the condensate dain line.


The 250 MUST have the condensate line connected. EC comes from gas supply problems and CO2 levels not being adjusted. LP units require 3/4" smooth gas pipe or 1" corrugated pipe minimum size. The LP regulator needs to be turned up to about 13 inches of water column and with all the gas appliances on, measure no less than 11 inches of water column. The CO2 levels must be measured by a qualified gas technician with a calibrated (with in 6 months) CO2 analyzer.

I get a ec code and have to reset it.


EC is no ionisation and is usually the result of a gas pipe or gas supply pressure problem. The other problem is the installer never adjusted the CO2 levels. If the yellow paint on the two screws inside the cabinet is still intact, the plumber did not do his job. Make sure this is done with calibrated CO2 analyzer that was calibrated within the last 6 months.

1600h same problem with ingiter


It is a control box issue but now I have to decide if I want to spend $270 to fix or for $299 buy a regular water heater. By my calculations being this is year three, the 15 year life expectancy of this 1600h water heater will cost me $1500 in parts alone.

Bosch HGS442UC Gas Oven won't light


Usually when an oven won't bake, it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself.

The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame.

Other causes Other reasons that your oven may not bake are:

  • The clock settings are incorrect (if you have timed baking or a self-cleaning oven).

  • The thermostat is defective.

  • The safety valve that prevents accidental gas flow is defective.

  • The selector switch is defective.
