The Kogan Series 9 Freestanding Dishwasher's seal can become loose if cutlery or other utensils hang outside the basket.
The seal is a rubber strip on the inside of the dishwasher that fits in a metal seam on the dishwasher.
If the seal is dislodged, it can be easily reinstalled by aligning with the crease in the dishwasher and slowly pressing it back into place.
