My BS3200 was working normally. I unplugged it for a day, plugged it back in, and now the only response from the machine is the red light on. No prompt for password, the only button that works is load, the doors open and the light comes on, but no other button gets a response. It appears to be stuck in standby mode. Any help greatly appreciated.

It's a fault in the eeprom, so you will need a new eeprom and microprocessor to get it working agian. thats a job only your dealer can do.

Just for a lark, unplug it again for about 10 minutes, and see what happens.
