Aprilaire Flow-Thru humidifiers have a solenoid with a small strainer filter in the body. These strainers should be inspected and cleaned when replacing the water panel. If the strainer becomes clogged the water pressure will tear it and pieces will jam the solenoid or loose pieces will block the orifice.
