I have noticed that some of the recovery boots’ chambers don’t fill properly. How to solve this?
First, check if any hose is not loosely connected to the boots.
Check to see if accidentally sat on hose tubes, or if they are bent or blocked in any way.
If nothing works, manually test all the hose tubes by unplugging them from the boots and then turn on mode D. This ensures full pressure from all holes. If you see some holes have uneven pressure, their hoses may be bent or blocked or accidentally stepped on.
