Product review (5 stars): Easy repair
Not much to say about this replacement water panel.  This was an easy job.  Open the door on the humidifier. Disconnect the water line - just pull it off, it's a rubber hose and is held on by friction.  Pull out the the old panel and holder  Remove the the original water panel from the holder.  Put the replacement panel into the panel holder and reinstall in humidifier.  Reconnect water hose, close humidifier door and you're good to go.  Took longer to write this then to perform the task.  The replacement panel comes with good instructions.
