GE Dishwasher Door Seal Leak From Bottom

Have had a leak around the door for some time. First leaked on the bottom of both corners around door. Called in A&E repair.- They put a new seal around the door and then said if that does not fix it I will have to purchase a new door.- Now it is leaking around the top and started damaged the bottom of the counter. This is only 5 years old. Could the problem be the latch for the door? If so can you tell me part number and the price you sell it for? GE Dishwasher GDT580SSF6SS, Serial# MF819653B
