Why wont takagi tk jr doesnt heat


Flowmeter.....Gas Pressure.....Ignition?
I'm not psychic.
Tk-Jr is a dependable 140-145,000 BTU 2nd Gen Unit SS Vent , <.82 EF.
Failure is a Tech Service issue and the Tech may need Factory Support from California. This is probably a pre-A.O. Smith/Takagi unit
Does the igniter spark 3 times than shut down and fan purge HE? Can you smell gas tracer (remember NG/LP is odorless w/o mercapthan in it)? Tech will need a digital Manometer for Line and Manifold Pressure Test. And a Multi-Meter Toll Free # on Unit or in Manual

Error message : e01 f09


First try holding down the cancel button for 10 seconds and releasing (might have to do this 2~3 times). The technician manual is located under the lower front panel. I've heard that locating the CCU (brain box, in lower right) freeing it up and giving it a couple of wacks has worked. F09 is pressure switch, E01 is Thermistor. The tech manual will be a great help!!

Richmond powervent model 6G40PV-40F Lockout 4-2 blink. What's wrong. What do I replace to fix?


1) Rheem-Richmond does not post service manuals:
Copy following link to identify service manual by type of gas control valve:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

2) For lockout, the air intake might be clogged or combustion parts dirty, causing overheating which will break TRD glass vial. Gas control may need to be replaced. Reset gas control by rotating knob to lowest temp for at least 6 seconds.

3) Call Rheem or local service tech.

Rtg74pvn2 rheem tankless water heater gas problem


1) You want the truth: Forget tankless.
There are many tankless water heaters with insoluble problems.
And endless problems.
Rheem knows it.

2) Do you really expect your home computer to work flawless after replacing motherboard?
Get your money back from Rheem, or get a full replacement.

3) OR fix water heater yourself today: Install tank-type gas water heater for $350 from local box store.
FYI: Do not buy Rheem, Richmond, Ruud, GE as these units from Rheem have problems that require service technicians.
Instead buy Whirlpool, American, State, Craftmaster, Reliance, Kenmore, as these units from AO Smith have fewer problems and can be repaired by homeowner using simple part replacement.

You ask for free nudge:
I have links for resourceful do-it-yourselfer since tankless is large and developing field that can take years of study.
For example tankless are prone to lime build-up and must be de-limed each year. Search utube for 'delime tankless' to help restore efficiency.

Best place to start is troubleshoot section in your product manual.

Have Error code FO, no hot water. Press reset and water gets warm for few seconds then goes off again.


1) BOSCH website shows error codes.
FO does not appear:
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/2400ESTechSupport/Troubleshooting/tabid/1295/Default.aspx

2) I do not see FO error code listed on Internet search
Other FO questions at fixya seem to have no answer:
http://www.fixya.com/tags/error_f0_bosch

3) At this point, I would suggest calling a service technician.
While waiting for service, read manual cover to cover several times.

4) Your manual is valuable resource, and shows the word 'maintenance' and 'troubleshoot' frequently.
Tankless are maintenance heavy, and should be de-limed each year.
U-tube search "delime tankless water heater."

5) Also explore Bosch website for your manual and other valuable information.

6) When service tech arrives, ask that person for tips and tricks about your unit that will help you maintain your water heater.

7) All costs are energy. Install DIY tank-type gas water heater and avoid the whole headache.

Makes low rumble noise when 2 or more faucets running hot water. New installation. Inlet vent: 3 feet with 3 Ls. Outlet vent 3 ft with 1 L. Gas: 3/4" all the way(no flex).


CALL BOSCH TECH SUPPORT, THE NUMBER IS BEHIND THE COVER, THERE ARE A SERIES OF DIP SWITCHES FOR THIS WATER HEATER THAT HAVE TO BE SET ACCORDING TO YOUR ELEVATION, VENT LENGTH, AND USAGE. THIS IS FIVE MINUTE FIX.
