Getting a f76 code on model # ncc-199 sv


F76 is usually a communication error between the remote and the heater. you may have just unplugged something inside the unit while it had power (don't do that). Just unplug the unit from the wall (or flip the breaker) and wait 10 sec and plug it back in again and the problem should fix itself. Otherwise there my be a loose wire going to your remote. In which case, try unplugging the remote and unit for 10 sec and plug the unit (only) back in with the remote disconnected. run your hot water and see if it works. if so it could be a problem with the remote or its wiring.

Tankless water heater model # RTGL74PVN is blinking 38 what does this mean


Copy following link for general troubleshoot and error codes:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code 36 does not show in any resource, including 2008 service manual, or 2012 product manual.
Check that remote control display is illustrating the correct number.
For example there is error code 35.

Water not as hot as it was.


Tankless require yearly service to keep burner and combustion parts clean and check electrical connections, gas solenoid, gas pressure, venting, etc.
Read product manual for advisories and recommended maintenance.
Yes, aren't you glad you saved the manual.
Always check that local area has affordable and qualified service technician for your brand before buying tankless.
Before calling service technician, copy following link for general troubleshoot resources, including some manuals, and links to Bosch.
http://waterheatertimer.org/pdf/No-Error-Code.pdf
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

Try turning temperature down.
The fact there is no error code, and the gas is not firing correctly, means you have a small unit with no error codes and PC board has failed ... or it means you have a unit with error codes and possibly bad PC board.
If problem is the PC board, then Bosch will send you new board, and expect same level of repair success as though your computer's motherboard was replaced.

You can buy ordinary box-store tank-type heater and install yourself same day for about $325.
Then maintain and fix it yourself. I recommend AO Smith/American/State/Reliance/Kenmore/Whirlpool since these are easy to maintain with clear directions in manual, plus AO Smith posts service manuals for the whole line of products, and any local plumber can fix them with ez-to-locate generic parts.

Rheem model 41vrp40n flashes twice and stops working


Error code means that you have electronic gas control valve.

Copy following link to identify gas control valve, read error code meanings for each, and download service manual relevant to each gas control, but not specifically Rheem since rheem does not post service manuals.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

The fact that water heater restarts, means that water heater is getting gas, getting sufficient air for combustion, thermister is ok, gas pressure is good, etc.
The fact that you unplug and replug water heater and it works, shows that you have power vent model.
Since water heater worked correctly before, 2 flashes with Rheem power vent model could mean that pressure switch has failed.

My water heater error code 1 model ee3250rd055v what does this mean


Water heater is not 100% identified.
Unknown if this is gas or electric heater.

Problem posted under Whirlpool water heaters typically made by American water heater company.
Call Whirlpool 877-817-6750.
They will ask for model number and serial number located on label on side of tank.
Call is answered in USA by trained person who can answer specifics about that model, including warranty, age, regular maintenance, error codes, and possible solution for that specific model and serial number.
I have found these folks to be helpful.

Whirlpool manuals do not show that specific model:
http://www.whirlpoolwaterheaters.com/support/manuals.aspx

If you have the energy smart electric water heater with electronic control board, then error code explanation shows on the control board. Error 1 or a single flash, is start-up failure and requires tank to be full of water. Read page 10 of manual. Make sure water heater is full of water and water is coming full stream out of tub spout before turning on power. Also disconnect power from unit, make sure water heater is full, and then reconnect power to see if unit resets.

My Bosch Water Heater keeps going off. I reset it and then A7 keeps coming up. We had a power outage for about 6 days. I do not have the manual. Do you know what it is and how to fix it? Thank...


Questions might be asking for a manual, and asks what error A7 means, and asks how to fix error problem, but model number of Bosch heater is not given.
Error codes are start-point for troubleshooting, and can include multiple causes.
So following answer provides general do-it-yourself resources, without saying that problem can be 100% diagnosed or fixed by homeowner.

1) Error code A7 is outlet temperature sensor fault.
Problems include: need for descaling, dirty inlet water filter, debris in faucet aerators, dirty wiring terminals, bad wiring harness, or bad temperature sensor.
http://waterheatertimer.org/pdf/Bosch-GWH2400ES-error-codes.pdf

2) Before calling service technician who can test failed parts and catch tankless up on yearly maintenance, open following links for Bosch resources including error codes, phone number, possible manual, and descaling instructions, and cleaning inlet filter:
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Rheem-De-lime-tankless.pdf
http://www.boschhotwater.com/Portals/7/TechBulletins/TWH-G1-12_Cleaning_inlet_filter.pdf

3) Product manual: Question posted under model 125HX-LP
Open following link for possible manual:
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/125HXTechSupport/InstallationManuals/tabid/542/Default.aspx

4) Do it yourself service bullitens for 125HX-LP

I can't get my pilot light turned on. I have a Rheem powervent water heater and I can't turn it on. I keep getting an error message that says "FVD interface failure/miswiring". What do I have to do to...


Hello,
Most likely your flame sensor wiring is partially burn't or has an open circuit fault that's giving you the error message. This wire starts at the gas control and ends next to the pilot assembly. It can easily be replaced using a small wrench to unscrew the end connector from the control and the flame sensor rod at the pilot assembly. Call Rheem and see if the water heater is still under warranty, but even if it isn't they can most likely order the part you need for you. The phone # is on one of the data decals on the side of the water heater tank. They will need the model # and serial # to order the part. Be sure you unplug the unit before working on it! Douglas

What does F-76 code mean on a Noritz M-069 panel


F76 is a communication error. It usually occurs if you connect or disconnect a quick connect cable or remote control when the tankless heater is connected to electricity. (If you have a quick connect system, make sure you only have 1 remote and 1 quick connect cable.) To get rid of the code, try disconnecting electricity for 20 seconds, reconnecting electricity, and turning the remote on. If the code returns, you may need to replace your quick connect cable, remote cable, or even remote control

F76 is a communication error between two quick connected heaters. To clear the code, disconnect power from both heaters, wait 20 seconds, then reconnect power.
