Fresenius Liberty Cycler Drain Cycle Problems Resolved?

I have more or less accepted that the Fresenius Liberty Cycler, while a life-saving piece of hardware, indeed does have extensive design faults. I have previously documented in this blog on numerous occasions that on more than half of the nights, I receive drain alarms. These alarms are beyond bothersome in that they require me to wake up, get out of bed, silence the alarm at the cycler, and stay upright until the drain cycle is complete, some 10-15 minutes usually, before I can return to bed and hopefully sleep. Try getting awakened every couple of hours by a Klaxon-type noise two or three times a night and see how you feel the next day. It is akin to being awakened by the General Quarters alarm aboard US Navy ships, where I have endured many.

I MAY have found a solution. I am, at this point, three nights into testing it and have gone three-for-three with no alarms. The solution is simple and obvious. I have provided four pictures below to illustrate what I am doing differently in setting up the Cycler initially which seems to have made a difference.

It involves snapping the cassette into the Cycler a little bit differently. In the past, I placed the plastic top of the cassette into the screw-heads in the Cycler and pressed the cassette at the area of the toggle to “snap” it in. I did not always hear a “snap” noise but the door closed and the Cycler went on with its setup with no further ado.

For the last three nights, I am still putting the top of the cassette under the two protruding screws in the Cycler, but then holding down the toggle clamp at the bottom with my finger (it is spring-loaded) before sliding the cassette into position, then releasing the toggle. This ensures the cassette is flat against the Cycler and the bottom is resting well within the toggle which is fully snapped in position.

The next four pictures are for clarification and are of my Cycler.
