In the las few days I've noticed my circ. pump getting very loud. You could never hear it running, but now you can almost hear it humming/click sound in the house. I pulled the panel hopeing it was just loose but it's not and it seems the motor is pretty warm. Is this an indication it's on the was out?? Also for any dealers or anyone that has had this does it have to die for the warranty? At least it's warm now.
