How to reset Samsung P1253 washer?

My samsung washer model P1253,had a blockage in the pipe from the drum to the pump,i have cleared the blockage and cleaned the pump out but when you switch the power on most of the red lights come on and the clock shows 2hrs, if you press any of the buttons it just beeps,the washer was halfway through a programme when it would not empty because of the blocked pipe,any ideas if it is possible to reset the panel?
