ᐅ Ikea Siphon Atlant – Siphon rotates

Hey IKEA enthusiasts!

I designed and assembled a kitchen myself at IKEA, and I’m more than satisfied!
However, a “small” issue is driving me crazy just before completion:

The trap under the sink keeps rotating and disconnecting the drain pipe from the wall.
I could go insane, honestly! Everything itself fits well and is watertight. But after a few minutes, there is a loud click and the drain under the sink twists away. This damages the silicone seal between the drain and the wall.
I can’t figure out why, since there’s no tension on the hose and everything is securely fixed to the sink.

Does anyone have any advice? :/

Best regards, Kathrin

Hello,
maybe the hose has not been cut to the correct length. Perhaps a picture could help with troubleshooting.

That's right, a picture would be very helpful...
