Water fill/ power socket flap

[Kimmy]

Anyone got a fix for an issue I’m having with the small flappy door that keeps popping open? The door in question is the grey plastic cover that covers the water supply inlet and the power socket?

seems a friction fit but mine doesn’t want to stay closed. Bumps in the road etc cause it to fly open and get stuck in the up position. Anyone else experienced similar? What did you do to fix the issue?

we have the same problem so we bought some small magnets and glued them on the door and recess this definitely works
