There is a four hour reset, however that will not fix your problem. You need a new burner assembly.

I just looked up the specs. It is only permitted up to 6560 ft above sea level and for that an altitude chip is required to be purchased.

2) Unit can have internal part failure for example PC board, and result is that you get no error code.
This would explain why re-setting the tankless works.

3) Unit could also have loose wire or loose connection.
Or maybe the heat exchanger needs to be de-limed.
Or incoming gas, or incoming air, or vent problem.
Or water pressure, or water flow.

4) Without an error code, the problem can be household plumbing problem.

Hi,
If you are getting the C7 code you should also be getting another code after that..like a 76 or a 79...
If you are not getting anything else then the best possibility is that your control board is bad...

There have been quite a few of these boards going bad and that would be my first guess as to your problem...
Some have been replaced by the factory for free...I would call them and see if you can get a new board from them...
At least call their tech. support first and let them walk you through some tests so that they can verify that the board is bad...they often will send you a new board on the spot then.
I have also found that the customer can often get further with the company then the contractor can..

Please comment back if you have any further questions..

Hi,
The problem is in the second stage heating element....or you have too light of wiring and breaker...
Did it just start to do this or is this a new install??

If it is new then the breaker may be bad or is too light...

If this just started to happen on a existing install then an element is bad...

please comment back with more details...

try cleaning your spark rod inside the unit and the other rod next to the spark rod on the side of the unit. Takagi use a emery cloth, rheem brass brush, noritz a emery cloth. but make sure that both of the rods that are in the flame chamber are very clean. It miss reading because of build up on the rods.

check for carbon build up on the flame rod or qualified technician to check it

thats a ignition failure.. Check for Gas to the unit.. or have a qualify technician check it

Hello. Move your thermocouple closer to the flame. If that doesn't solve it, replace the thermocouple. J.

Always shut down anything electrical low voltage or other BEFORE attempting anything. The two wires attached to the remote can be extended with longer wire and wire nuts. If you look at your owners manual it will tell you that you can hook up additional controllers (up to four I believe) and have one in each bath, at the kitchen and at the unit. Pressing the priority button at whatever remote you are at will make that remote control new temps to unit and display at all remotes.Don't get crazy with too many wire nuts!

Some tankless water heaters do not have a pop-off valve. It will be on the top or side if it has one.
