User Suggested Solutions

Inspect the broken rail support lock and remove any remaining pieces. Purchase a replacement lock from an authorized Miele dealer. Install the new lock by aligning it with the rail and securing it in place. Test the rail for stability before use.
Check the alignment of the rail and ensure it is not bent or damaged. If misalignment is found, adjust the rail to ensure it is straight before replacing the lock.
If the lock is not available, consider using a temporary fix with strong adhesive to hold the rail in place until a replacement can be obtained.
