Water Heater Help

Thanks for all the suggestions. I will play with it over the next week or so and look into some of these suggestions. I am confident it is not an air in the line issue. I am very familiar with what that looks like and this seems to be something else. I have not had a chance to check the model/brand of the unit yet, but is there a general location of the control board? Is that something I can access from the outside? I dont recall seeing it in an obvious location. I will check all connections and use the air compressor to blow everything out first. If I still have issues I'll start looking to test and replace parts.

Generally speaking, will appliance manufacturers ever honor warranty when you do your own work? Not sure how long the warranty is, but if it turned out to be a control board, has anyone had the brand cover the cost without taking it to the dealer?

Thanks again all!
