Customer Question

Have Model 800 Aprilaire. Fill lite turns red. Manual says 'high water probe does not detect water after fill value is energized'. Is the filter just bad and needs to be replaced?

Yes just sounds like a plugged filter on the unit and then the probe is not detecting the water. Replace the filter and you should be good to go!

Can I just replace replace the filter while you stay on the line?
Customer: replied 7 months ago.
Replaced the filter with a new one. The one I took out looks brand new. No deposits, clean. Was wet, so water was getting into it. I don't see anything plugging it. Replaced the filter about 30 minutes ago. Have power On lite green, Fill lite green and Steam lite green. When I reset it this morning, it took about 40 minutes before the Fill Lite turned red.
