Just went on a water furnace for maintenance and an error code. Asked what code was , don’t remember. It takes a couple days to show up but if reset system and turn fan from auto to on error doesn’t happen ?? Maybe a drain issue ? Drain was slimy but not holding water in pan. Loop needed juicing. Added maybe a pint to get back up to 30 psig. 18* temp drop (air). Without knowing the code I’m really at a loss. And why with fan on instead of auto would error go away. Been running fine for a month keeping setpoint.

Any ideas?
Lol. Figured why I didn’t get a response. As cruddy as drain was I just wonder if running blower continuously help stop it ? Who knows. Told them to run it in auto and call me with error if it occurs again.
If they don't tell you about the bug anymore, then everything works fine.
