My Navien NCB180E combi has stopped producing water flow from the condensation drain tube. it used to oroduce a half gallon a month. Is something plugged or is there a filter i should be checking?

    1/2 gallon a month? that is not much. How do you know this? Does the drain spill into a bucket that you empty manually?

    If there is very little condensation, then maybe there is less due to the air intake. the change in season may provide different conditions resulting in less condensation.What is connected to your boiler? indirect water heater? baseboard radiators? cast iron radiators? Radiant floor tubing?

    After you make that expensive repair and you still have the same problem, What will you check next?
