Whirlpool dishwasher with 8 programs

Peace be upon you and the mercy of Allah and His blessings Used Whirlpool Italian brand dishwasher with 8 programs. It has an issue: when I turn it on, a sound comes out as if the door is not properly closed, and it does not start washing. I asked about the problem and was told that the button card needs to be replaced. Other than that, the dishwasher is in good condition. Selling to the highest bidder, please do not undervalue the item. O Allah, provide for me and through me
