DIPLOMAT ADP 8352 All lights on plus beeping dry tray ,salt light on?

Hi Lara, all the lights coming on are because you have opened the door.Can you see the lights that are on when the door is closed.Only then will it give you a true error code of lights.When you start the dishwasher, the drain pump comes on,then it fills.If the bleeps start in 5 to 10 seconds,it may be that the drain pump has a fault.When you turn it on does it make a humming sound,If yes,then the drain pump is jammed.If you can hear the drain pump then it could be the water tap is off,the fill hose is kinked or the valve is open circuit.Hope this helps. All the best.
