Ddolphin triton plus bought 2016 doors arent shutting tight

Air is getting into my robot I believe because the doors around the filter cartridges are not clicking and closing shut. My machine power light turn on but then stop. The robot does not sink. How do I get the doors to click jn and shut properly again? Anyone else have this issue? It's a maytronics dolphin Triton plus 99991079-pc bought 2 years ago. Never have had any problems with it.
