Greetings!! My heater will show "heat" for about 9-10 seconds and then stop showing heat. I'm getting no error codes. Any help would be greatly appreciated. Thank you!

Usually if one of the safety devices stops the heater it would show up as a light or error indication somewhere. This could be from low flow or from overheating (temp too high). Perhaps bumping this thread up may get you a better response.
