It won't stop beeping and the lights keep flashing non-stop (see video). We had to shut off the power at the breaker to make it stop and when powered back up it starts again. I purchased this unit because it is very quiet and has a lot of power. I am hoping Cavaliere will respond with a solution. I understand that the unit is out of warranty but I believe a major appliance purchase such as this  one that has to actually be installed  should last longer than a year and a half.
