Popcorn, labels from food jars, film covers and broken glass, as well as scraps of food, could all block the machine filter. Clear film may also be hard to see if you don’t look closely.
Remove the filter and give it a thorough wash before replacing it. Not all dishwashers have their filter in the same place so you might need to refer to the instruction manual for this.
