I have a Necht dishwasher.

Question

I have a Necht dishwasher. The dishwasher door does not close therefore I can not get it to operate. Someone came to have a look at it and they said that it needs a replacement for the door latch. The problem is I do not know where I can find this replacement for this brand ( Necht). Can you tell me where I can burchase or order it from? a website or a shop.
