diplomat ADP8322 !!!!!!!!!!!!?

i have a diplomat ADP8322, evrytime i close the door it starts beeping but sounds like it starts up,after 5 seconds or so it stops working but carries on beeping, i open the door and the beeping stops but the start light just flashes continueously,there does not seem to be no pattern to this it just flashes endlessly,the rinse is highlighted,i have held the start button down and it stops flashing,it then allows me to choose a function but as soon as i close the door it goes back on to rinse and the beeping starts again...plase help because i am a tenant in the place and cant afford to get an engineer out...
