Electrolux Dishwasher catch or lock

Hi All

My electrolux integrated dishwasher door won't lock closed when shut. It's like it's not latching. The dishwasher still working - I jam a stool up against it when we turn it on. Problem is if one of the kids messes with the switches When the door is open it also turns on, 🙈. Obviously not ideal and went to look at a spare part today but not sure if I need a catch or lock. Both come up on espares when is seach the model number ESL66010. Any thought?

Cheers A
