The beeping is to alert you to the fact it has a fault. The error code will be flashing on the display. When you press a button you cancel the beeps but they will start up again some time later. Unless you can read the error code then you will not know what is causing the fault & nobody here can see for you. Best to call a technician. Good chance the fault will be something that would need the tech. anyway.
