Make sure all the valves at the water filter are open this has popped up on a lot of these issues. Don’t know how cold it is there is it possible a line is frozen? Sometimes the control valve handles slip and they look like they are set correctly but are not correct. Does your pump run? Did you fill the water filter housing with antifreeze? The pump can have a difficult time pumping all the air out of the housing.
Thanks, my fear is a line is frozen. Hoping not. I'll try filling up the filter with AF and see if that does anything. I checked the valves and tried different configurations, but got nothing. I'll keep plugging away till I figure it out, if you have any other ideas I am open to them.
Put a heater in the wet bay for several hours to see if you can get the pump warmed up. I keep a heater going in the wet bay anytime I don’t have antifreeze in the system. That way you can eliminate a frozen pipe in the wet bay. Good luck. And ask if you have any other questions.
