2 flashing lights at the what seems to be the end of cycle?

i recently had a problem with my diplamate ADP8352. 3 lights would flash about 10 minutes into a cycle. i then found this site and somebody said i had a water leak which i have since fixed. but now the dishwasher it seems to do a cycle and the dishes are clean but it bleeps several times stops then bleeps again. when i open the door the first 2 panel lights flash, so if you close the door it sound like a pump or something is still going like it hasnt finshed properly. but it then starts to bleep again. thanks daryl
