Dishwasher keeps getting blocked!!

I was thinking we will have to buy a new dishwasher yet you have all inspired me to try and fix it. The pipe being squished would make complete sense

I just pour the vinegar in the dishwasher. I also cleaned out the filters that I could from inside the dishwasher and washed down the door & the seals etc...
