SOURCE: Keep getting error codes and have to reset too often

This paticular problem your having is specific to the jumper in the heater. The jumper is for condensing heaters. Your heater does not have the specific wiring or computer for condensing. So they added a jumper in the wiring. It is failed or failing. It should ohm out at about 120ohms. sometimes its just a loose connection. Check this out, and called 1-800-642-3111, they have been very busy, but leave them a message and they will call you back.

SOURCE: Noritz tankless water heater not producing hot water

I called Noritz error code 16 is a overheat problem. Noritz say's to flush your coil with vinegar or CLR.
Use a small pump to recirculate the CLR or vinegar through the system for 45 minutes and flush with fresh water. This worked for me.

did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

SOURCE: My Paloma tankless water heater flashes C2 11 error code

I just had the same problem and I fixed it in about an hour or 2. First shut off the gas,water and power(unplug it) Take off the cover There are about 20 screws above the electrical circuit board. You have to remove all of those screws to remove plate that is covering the burner assembly. The burner assembly has these 3 pins that look like number 7's these are covered with build up and gas can't flow right. That's why you get the c211 error not enough gas. Take a wire brush and gently remove any build up, I also cleaned the thermocoupler which is next to the burners. It looks like a metal pin with a couple of wires coming out of it this was also very dirty. I took a can of air and basically freshened it up It works perfect now. Email me with any Q's at Mario@myredr.com Good Luck All that you need is a long phillips screw drive and a drill because its about 25 screws
The burner assembly has 2 screws all the in back underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

We are receiving error code E27


The manual states E28 is a Mixing valve initialization failure.
With all failures on this model, make sure your condensate line and check valve are clean and clear. I see many different issues that come up that seem to go away after removing, cleaning and replacing the condensate line.

Rinnai RL94i - Produces hot water for 3 minutes, then stops


I just had this exact problem. It kept getting worse until we had no water. Our Rinnai tankless hot water heater started the same way though, with hot water for a few minutes and then would shut off with an error code 10. We just had to shut the hot water off and then back on, wait a minute or so and we had hot water back for a few minutes. Our unit would come on with a loud vibrating noise and remain until it shut off with an error code 10 (air flow fault). The solution was to remove the blower fan and blow out the squirrel cage. Ours had moths in it. We also vacuumed out the fan housing. Be careful to mark any wires you disconnect and take pictures before removal. Our unit is now almost silent when it comes on and supplies endless hot water.

Eternal GU-195S Hybrid water heater


Is this new installation? Or old installation that stopped working?
Here's the 100% solution. And it applies to all brands, models, types, of tankless water heater, no matter which error code:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html
People should avoid complicated water heaters that claim 'energy star' and '98% efficiency' while proclaiming 'endless hot water' as if the laws of physics, economics and common sense can suddenly be suspended if only the customer would buy expensive, complicated water heater that cannot be maintained or repaired by customer, and there are no qualified technicians who live in your area.
Otherwise you need a service manual, or contact eternal manufacturer. 1-866-946-1096
http://eternalwaterheater.com/pdf/downloads/GU100.pdf
Error E02 does not show in manual.
E2 is ignition failure, which on other brands can be failed PC board... and inadequate incoming air supply, or venting, or failed sensor, dirty combustion parts, air or water in gas line, low gas pressure, wrong gas, etc, or multiples from list above.
