The purpose
Of this tubing is it is all part of the complicated automatic control system which monitors suction before and after the bag compartment to trigger the automatic shut off and pop the bag door open when suction efficiency is reduced from the bag filling with dirt. I’ve never quite understood why they have the tube going back to the cordwinder except for that perhaps the system needs access to a point where there is no air being sucked in or blown out and that would occur inside the cord reel which has access to the air outside the cleaner through the hole where the cord comes out and was a better place to obtain this than placing a hole somewhere on the cleaner body which someone could come along and fill up or tape over for some reason thinking it shouldn’t be there. I’m sure the marvelous engineer who developed the system knows why and perhaps an Aerus repair person likely knows why it needs to be there as well. I think that tube goes direct from the back corner of the bag compartment to the cordwinder but I could be wrong, there’s several connections in and around the bag compartment for it all and another in the suction port where the hose attaches. It’s quite fascinating how it all works to me and I’d love to read a study on it someday.
Definitely hold the cord when you remove the cordwinder cover. It should be set on a table with the outside side (gold painted side) down when you do it, maybe ebpevn put it in a vice so it stays put so you have your hands free. The spring will not explode unless you attempt to remove the reel or if you let go of the cord it will likely whip around 3 more times or so..if you attempt to remove the cord spool...then that could happen as the spring is wrapped around a smaller spool that you will see a part of hiding behind the cord spool. It is not fastened in so if you pull off the cord spool the spring spool will come off with it and then it will indeed explode like the snake in a can unless you hold both pieces together, once the spring spool comes off itks mounting post, it can then unwind itself. But if you hold it you can slowly unwind the spring around the cord spool until it is unwound. But likely if there’s nothing wrong with the cordwinder spring system itself I would not bother to remove the spools at all, just count how many time ps you have to rotate the cord spool using the exit hole as your guide until the tension is reduced off the spool. You will need to reload this tension before reassembling.
Trust me, unit is a nightmare if it explodes and could cut your hands up and it is basically a “tape” of spring steel. There is a keyhole at either end where it fastens to each of the spools. One must not overwind it when reassembling or it could come off the spool when you pull the cord all the way out, but should be done about 3 additional spins of the cord spool reel once the cord is fully back on its spool to allow the spring to be tight enough to roll up even the last few feet of cord. Looks like your cord end has been replaced, if some of the cord was shortened you will actually have more rotations of the reel you can wind the spring, but it really depends on how many feet of cord has been deleted from the original length.
I’d consider having the cord replaced if it’s the original. Sometimes the cords short out where they are tied at the end of the reel. Note it is looped under itself from the factory, this is correct to prevent tension on the inner connection of the cord.
Clean the electrical racetracks on the spool when you have it opened and the contacts on the inside of the cover that make contact with the racetracks.
